Modulators of Proteins with Phosphotvrosine Recognition Units
Field of the Invention
The present invention relates to novel protein tyrosine phosphatase modulating
compounds, to methods for their preparation, to compositions comprising the
compounds, to their use for treatment of human and animal disorders, to their
use for
purification of proteins or glycoproteins, and to their use in diagnosis. The
invention
relates to modulation of the activity of molecules with phosphotyrosine
recognition
units, including protein tyrosine phosphatases (PTPases) and proteins with Src-

homology-2 domains, in in vitro systems, microorganisms, eukaryoic cells,
whole
animals and human beings.
Background of the Invention
Reversible phosphorylation of proteins is a prevalent biological mechanism
for modulation of enzymatic activity in living organisms. Tonks et al., J.
Biol. Chem.,
263(14):6722-30 (1988). Such reversible phosphorylation requires both a
protein
kinase (PK), to phosphorylate a protein at a particular amino acid residue,
and a
protein phosphatase (PP), to remove the phosphate moieties. See generally,
Hunter,
Cell, 80:225-236 (1995). Recently, it has been estimated that humans have as
many
as 2000 conventional PK genes, and as many as 1000 PP genes. Id.
One major class of PK's/PP's - the protein serine/threonine kinases and
protein
serine/threonine phosphatases - have been shown to play critical roles in the
regulation of metabolism. See generally, Cohen, Trends Biochem. Sci., 17:408-
413
(1992); Shenolikar, Ann. Rev. Cell Biol., 10:55-86 (1994); Bollen et al.,
Crit. .Rev.
Biochem. Mol. Biol., 27:227-81 ( 1992). As their name suggests, these enzymes
phosphorylate and dephoshphorylate serine or threonine residues of substrate

2
proteins. Inhibitors of protein serine/threonine phosphatases and kinases have
been
described. See, e.g., MacKintosh and MacKintosh, TIBS, 19:444-448 (1994).
The protein tyrosine kinases/phosphatases comprise a second, distinct family
of PK/PP enzymes of significant interest, and have been implicated in the
control of
normal and neoplastic cell growth and proliferation. See Fisher et al.,
Science,
253:401-406 ( 1991 ). Protein tyrosine kinase (PTK) genes are ancient in
evolutionary
origin and share a high degree of inter-species conservation. See generally
Hunter
and Cooper, Ann. Rev. Biochem., 54:897-930 (1985). PTK enzymes exhibit high
specificity for tyrosine, and ordinarily do not phosphorylate serine,
threonine, or
hydroxyproline.
More than 75 members of the PTPase family have been identified in
eukaryotes, prokaryotes, and even viruses. Tonks and Neel, Cell 87:365-368.
Protein
tyrosine phosphatases (PTPases) were originally identified and purified from
cell and
tissue lysates using a variety of artificial substrates, and therefore their
natural
I S functions and substrates were not obvious. However, their roles in
cellular processes,
including cell-cell contact and cell adhesion, and growth factor and antigen
signaling
events, have begun to be elucidated.
PTPases are generally grouped into two categories: those which have both an
extracellular domain and an intracellular catalytic domain, the receptor
PTPases (R-
PTPases); and those which are entirely intracellular. For R-PTPases much
effort has
been directed at determining the function of the extracellular domain. Most of
the R-
PTPases contain extracellular domains which are structurally similar to
domains
found in known adhesion molecules; these domains include fibronectin type III
repeats, immunoglobulin domains, and cadherin extracellular repeats. See
generally
Brady-Kalnay and Tonks, Curr. Opin. Cell. Biol. 7:650-657 (1995); Streuli,
Curr.
Opin. Cell. Biol. 8:182-188 ( 1996). This homology with proteins known to be
involved in adhesion suggested a role for these R-PTPases in regulating or
mediating
adhesion events. For several of the R-PTPases, this has now been demonstrated.

Cells form specialized structures at the sites of cell-cell contact (adherens
junctions) and cell-extracellular matrix contact (focal adhesion). Multiple
signal
transduction molecules are recruited to these sites, including several PTK's;
and these
sites are characterized by increased protein tyrosine phosphorylation. These
sites are
impermanent, and are created and destroyed as required for cell mobility. As
enhanced tyrosine phosphorylation is characteristic of the formation of
adherens
junctions and focal adhesions, it is Iikeiy that protein tyrosine
dephosphorylation by
PTPases serves to regulate the creation and destruction of the sites.
Supporting this,
several studies have shown that treatment with a general PTPase inhibitor
(vanadate)
resulted in increased focal adhesion formation and increased cell spreading.
Volberg
et al.) The EMBO J. 11:1733-1742 (1992); Bennett et al., J. Cell Sci. 106:891-
901
( 1993). Importantly, the broadly-expressed LAR R-PTPase has been demonstrated
to
localize to focal adhesions, apparently via the LAR-interacting protein LIP.1.
Serra-
Pages et al., The EMBO J. 14:2827-2838 (1995). As PTPB and PTPa, both R-
PTPases, also associate with LIP.1 [Pulido et al., Proc. Natl. Acad. Sci.
92:11686-
11690 ( 1995)], it is likely that these two phosphatases can also localize to
focal
adhesions. Most significantly, LAR only localized to the portion of the focal
adhesion which is proximal to the nucleus, and is thought to be undergoing
disassembly. Thus it is likely that these phosphatases act to negatively
regulate focal
adhesion formation, acting to enhance the destruction of the focal adhesion
site.
R-PTPases may also act to positively regulate adhesion. Adherens junctions
contain, among others, adhesion receptors termed cadherins which mediate cell-
cell
contact through homophilic binding; the cadherins associate with a-, (3-, and
y-
catenins, intracellular proteins which interact with cortical actin.
Association between
cadherins and catenins serves to stabilize the adherens junction and to
strengthen cell-
cell contact. See generally Cowin, Proc. Natl. Acad. Sci. 91:10759-10761 (
1994).
Association of cadherin with (3-catenin is decreased by tyrosine
phosphorylation of ~i-
catenin [Kinch et al., J. Cell. Biol. 130:461-471 ( 1995); Behrens et al.) J.
Cell. Biol.
120:757-766 (1993)]; moreover, treatment with the PTPase inhibitor vanadate
inhibits


CA 02275610 1999-06-15
WO 98/27065 PCT/tJS96/2050$
4
cadherin-dependent adhesion [Matsuyoshi et al., J. Cell. Biol. 118:703-714
(1992)).
Collectively, these data indicate that PTPase activity is critical in
maintaining
cadherin-mediated cell aggregation. The R-PTPases PTP~. and PTPx associate
intracellularly with cadherins, and colocalize with cadherins and catenins to
adherens
junctions [Brady-Kalnay et al., J. Cell. Biol. 130:977-986 (1995); Fuchs et
al.) J. Biol.
Chem. 2 71:16712-16719 ( 1996)]; thus PTP~t and PTPx are likely to enhance
cadherin
function by limiting catenin phosphorylation.
In addition to their catalytic function in regulating adhesion events, several
R
PTPases have direct roles in mediating adhesion through their extracellular
domains.
PTPx and PTPp. mediate cellular aggregation through homophilic binding [Brady
Kalnay et al., J. Cell. Biol. 122:961-972 (1993); Gebbink et al., J. Biol.
Chem.
268:16101-16104 ( 1993 ); Sap et al. , Mol. Cell. Biol. 14:1-9 ( 1994)] . The
neuronal
PTP~ (which has also been called R-PTP[i) binds to contactin, a neuronal cell
recognition molecule; binding of PTP~ to contactin increases cell adhesion and
neurite outgrowth. Peles et al.) Cell 82:251-260 (1995). A secreted splice
variant of
PTP~ (also known as phosphacan) binds the extracellular matrix protein
tenascin
[Barnea et al. J. Biol. Chem. 269:14349-14352 ( 1994)), and the neural cell
adhesion
molecules N-CAM and Ng-CAM [Maurel et al., Proc. Natl. Acad. Sci. 91:2512-2516
( 1994)]. As the expression of PTP~ is restricted to radial glial cells in the
developing
central nervous system, which are though to form barriers to neuronal
migration
during embryogenesis, it is likely that the interaction of PTP~ with
contactin,
tenascin, N-CAM, and/or Ng-CAM acts to regulate neuronal migration. This has
been demonstrated for a related R-PTPase, DLAR, in Drosophila [Krueger et al.
Cell
84:611-622 (1996)].
Because tyrosine phosphorylation by PTK enzymes usually is associated with
cell proliferation, cell transformation and cell differentiation, it was
assumed that
PTPases were also associated with these events. For several of the
intracellular
PTPases, this function has now been verified.


CA 02275610 1999-06-15
WO 98127065 PCT/US96120508
SHP 1 (which has also been called SHPTP l, SHP, HCP, and PTP-1 C [see
Adachi et al., Cell 85:15 (1996)]), an intracellular PTPase which contains two
amino-
terminal phosphotyrosyl binding Src Homology 2 (SH2) domains followed by the
catalytic PTPase domain, has been demonstrated to be an important negative
regulator
_ 5 of growth factor signaling events. See generally Tonks and Neel, supra;
Streuli,
supra. In mice, loss of SHP 1 function (the motheaten and viable motheaten
phenotypes) causes multiple hematopoietic defects resulting in
immunodeficiency and
severe autoimmunity; culminating in lethality by 2-3 weeks or 2-3 months
depending
on the severity of SHP 1 deficiency. Although these mice have reduced numbers
of
hematopoietic cells, suggesting defects in development and maturation, those
cells
which survive and enter the periphery are characterized by hyper-
responsiveness to
growth factors and antigen. This observation suggested a role for SHP 1 in
negative
regulation of hematopoietic signaling events.
This has now been well-established for the erythropoietin receptor (EpoR), a
member of the cytokine receptor family (which also includes the receptors for
interleukins 2, 3, 4, 5, 6, 7; granulocyte-macrophage colony stimulating
factor, and
macrophage colony stimulating factor). SHP 1 associates via its SH2 domains
with
tyrosine-phosphorylated EpoR, causing dephosphorylation and inactivation of
the
EpoR-associated Janus kinase 2 and termination of the cellular response to
erythropoietin. Klingmuller et al.) Cell 80:729-738 (1995). Mutation of the
tyrosine
on the EpoR to which SHP 1 binds results in enhanced cell proliferation to
erythropoietin in vitro [Klingmuller, supra]. In humans, mutation of the EpoR
resulting in loss of association with SHP 1 causes autosomal dominant benign
erythrocytosis, which is characterized by increased numbers of erythrocytes in
the
periphery and increased hematocrit. de la Chapelle et al., Proc. Natl. Acad.
Sci.
90:4495-4499 (1993).
SHP 1 also appears to be a negative regulator of the cellular response to
colony
stimulating factor-1 (CSF-l, a major macrophage mitogenic cytokine), as cells
from
viable motheaten and motheaten mice, which have reduced or absent SHP 1
function,


CA 02275610 1999-06-15
WO 98/Z7065 PCT/US96/20508
6
are hyper-responsive to CSF-1 in vitro. Reduced SHP1 expression also results
in
increased cellular response to interleukin 3 [Yi et al., Mol. Cell. Biol.
13:7577-7586
(1993)]. Collectively, these observations suggest that SHP1 functions to limit
the
cellular response to cytokines and growth factors by reversing the tyrosine
phosphorylation of key signaling intermediates in these pathways.
PTPases appear to play a homologous role in the insulin signaling pathway.
Treatment of adipocytes with the PTPase inhibitor vanadate results in
increased
tyrosine phosphorylation and tyrosine kinase activity of the insulin receptor
(InsR),
and enhances or mimics the cellular effects of insulin including increased
glucose
transport. See, e.g., Shisheva and Shechter, Endocrinology 133:1562-1568
(1993);
Fantus, et al., Biochemistry 28:8864-8871 ( 1989); Kadota, et al., Biochem.
Biophys.
Res. Comm. 147:259-266 ( 1987); Kadota, et al., J. Biol. Chem. 262:8252-8256
( 1987). Transiently induced reduction in expression of two PTPases, the
intracellular
PTPase PTP-1B and the R-PTPase LAR, resulted in similar increases in the
cellular
response to insulin. Kulas, et al., J. Biol. Chem. 270:2435-2438 { 1995);
Ahmad et al.,
J. Biol. Chem. 270:20503-20508 (1995). Conversely, increased cellular
expression of
several PTPases (PTPa, PTPe, CD45) in vitro has been demonstrated to result in
diminished InsR signaling [see, e.g., Moller, et al., J. Biol. Chem. 271:23126-
23131
( 1995); Kulas et al., J. Biol. Chem. 271:755-760 ( 1996)]. Finally, increased
expression of LAR was observed in adipose tissue from obese human subjects
[Ahmad, et al., J. Clin. Invest. 95:2806-2812 ( 1995)]. These data provide
clear
evidence that PTPases negatively regulate the insulin signaling pathway.
While many of the PTPases function to negatively regulate cellular
metabolism and response, it is becoming increasingly evident that PTPases
provide
important positive signaling mechanisms as well. Perhaps the best example of
such a
positive regulator is the hematopoietic R-PTPase CD45. See generally Streuli,
supra;
Okumura and Thomas, supra; Trowbridge, Annu. Rev. Immunol. 12:85-116 (1994).
CD45 is abundantly expressed on the cell surface of all nucleated
hematopoietic cells,
in several alternative splice variants. T and B lymphocytes which lack CD45

expression are incapable of responding normally to antigen, suggesting that
CD4S is
required for antigen receptor signaling. Genetically engineered mice which
lack
expression of CD4S exhibit severe defects in T lymphocyte development and
maturation, indicating an additional role for CD4S in thymopoiesis. The major
_ 5 substrates for CD4S appear to be members of the Src family of PTK's,
particularly
Lck and Fyn, whose kinase activity is both positively and negatively regulated
by
tyrosine phosphorylation. Lck and Fyn isolated from CD4S-deficient cells are
hyperphosphorylated on negative regulatory tyrosine residues, and their PTK
activity
is reduced. As CD4S can dephosphorylate and activate purified Lck and Fyn in
vitro,
these data suggest that CD45 maintains the activity of Lck and Fyn in vivo
through
dephosphorylation of these negative regulatory tyrosines and that this is an
important
mechanism for maintaining lymphocyte homeostasis.
A second PTPase which is now believed to play an important positive role in
signal transduction is the intracellular, SH2-domain-containing. SHP2 (which
has also
been called SHPTP-2, SHPTP-3, syp, PTP2c, and PTP-1D [Adachi, et al., supra]).
.See generally Saltiel, Am. J. Physiol. 270:E375-38S (1996); Draznin,
Endocrinology
13 7:2647-2648. SHP2 associates, via its SH2 domains, with the receptor for
platelet-
derived growth factor (PDGF-R), the receptor for epidermal growth factor (EGF-
R),
with the insulin receptor, and with the predominant substrate of the InsR,
insulin
receptor substrate 1 (IRS 1 ). Bennett, et al., Proc. Natl. Acad. Sci. 91:733

(1993). SHP2 PTPase activity is required for cellular response to EGF and
insulin, as
competitive expression of inactive forms of SHP2 results in diminished
signaling
2S events and reduced cellular responses to EGF and insulin. Milarski and

Due to the fundamental role that PTPases play in normal and neoplastic
cellular growth and proliferation, a need exists in the art for agents capable
of
modulating PTPase activity. On a fundamental level, such agents are useful for
elucidating the precise role of protein tyrosine phosphatases and kinases in
cellular
signalling pathways and cellular growth and proliferation. See generally
MacKintosh
and MacKintosh, TIBS, 19:444-448 ( 1994).
More importantly, modulation of PTPase activity has important clinical
significance. For example, PTP-1 B overexpression has been correlated with
breast
and ovarian cancers [Weiner et al., J. Natl. Cancer Inst., 86:372-8 (1994);
Weiner et
al., Am J. Obstet. Gynecol., 170:1177-883 ( 1994)], and thus agents which
modulate
PTP-1 B activity would be helpful in elucidating the role of PTP-1 B in these
conditions and for the development of effective therapeutics against these
disease
states. The important role of CD45 in hematopoietic development and T
lymphocyte
function likewise indicates a therapeutic utility for PTPase inhibitors in
conditions
that are associated with autoimmune disease, and as a prophylaxis for
transplant
rejection. The antibiotic suramin, which also appears to possess anti-
neoplastic
indications, has recently been shown to be a potent, irreversible, non-
competitive
inhibitor of CD45. See Ghosh and Miller, Biochem. Biophys. Res. Comm. 194:36-
44
( 1993). The negative regulatory effects of several PTPases on signaling
through
receptors for growth factors and cytokines, which are implicated in normal
cell
processing as well as disease states such as cancer and atherosclerosis, also
indicate a
therapeutic potential for PTPase inhibitors in diseases of hematopoietic
origin.
The PTPase Yop2b is an essential virulence determinant in the pathogenic
bacterium Yersinia, responsible for bubonic plague. Bliska et al., Proc. Natl.
Acad
Sci. USA, 88:1187-91 ( 1991 ), and thus an antimicrobial indication exists for
PTPase
inhibitor compounds, as well.
PTPases have been implicated in diabetic conditions. Experiments with one
family of PTPase inhibitors, vanadium derivatives, indicate a therapeutic
utility for
such compounds as oral adjuvants or as alternatives to insulin for the
treatment of

hyperglycemia. See Posner et al., J. Biol. Chem. , 269:4596-4604 ( 1994).
However,
such metal-containing PTPase inhibitors act in a fairly non-specif c fashion
and act
with similar potencies against all PTPase enzymes.
In addition to vanadium derivatives, certain organic phosphotyrosine mimetics
.. 5 are reportedly capable of competitively inhibiting PTPase molecules when
such
mimetics are incorporated into polypeptide artificial PTPase substrates of 6-
11 amino
acid residues. For example, a "natural" (phosphorylated tyrosine} PTPase

competitively inhibited PTP-1B. However, such hexapeptide inhibitors
nonetheless
possess drawbacks for PTPase modulation in vivo. More particularly, the
hexapeptide
inhibitors described by Burke et al. are sufficiently large and anionic to
potentially
inhibit efficient migration across cell membranes, for interaction with the
catalytic
10 domains of transmembrane and intracellular PTPase enzymes which lie within
a cell
membrane. A need exists for small, organic-molecule based PTPase inhibitors
having
fewer anionic moieties, to facilitate migration across cell membranes.
For all of the foregoing reasons, a need exists in the art for novel compounds
effective for modulating, and especially inhibiting, the phosphatase activity
of protein
tyrosine phosphatase molecules.

Biological Protocols
PTP-1B Gene Cloning and Protein Purification
The following procedure was conducted for recombinant production and
purification of protein tyrosine phosphatase PTP-1 B, for use as a substrate
in PTPase
inhibition assays.
A. Production of a PTP-1B cDNA
A human placental cDNA library was synthesized in a 50 ul reaction
containing 1 ug human placental poly(A)+ mRNA (Clontech, Palo Alto, CA), 4 ul
random hexamer primers, 8 ul of 1 OmM dNTPs (Pharmacia, Piscataway NJ), 1 ul
(200
U/ul) Moloney marine leukemia virus reverse transcriptase (Gibco-BRL, Canada),
0.5
ul (26 U/ul) RNAsin (Promega, Madison WI), and 12 ul Sx buffer (Gibco-BRL).
The
synthesis reaction was incubated at 37~C for one hour and then heat
inactivated at
95'C for five minutes.
A PTP-1B cDNA was amplified, using polymerase chain reaction (PCR),
from the cDNAs synthesized as described above. More particularly, based on the
published sequence of PTB-1 B, two PCR primers were synthesized to amplify a


CA 02275610 1999-06-15
VSO 98/27065 PCT/US96/2050$
88
portion of the PTP-1 B coding sequence known to encode a 321 amino acid
fragment
containing the PTP-1B catalytic domain and having PTPase activity. See Hoppe
et
al., Eur. J. Biochem., 223:1069-77 (1994); Barford, D., et al., J. Molec.
Biol.,
239:726-730 (1994); Chernoff et al., Proc. Natl. Acad. Sci. USA, 87:2735-2739
( 1990); Charbonneau et al. Proc. Natl. Acad. Sci. USA, 86: 5252-5256 ( 1989).
The
primers had the following respective sequences:
PTP-1B-A(S') (SEQ ID NO: 1)
5'CGCACTGGATCCTCATGGAGATGGAAAAGG3'
PTP-1B-B(3') (SEQ ID NO: 2)
5' CTCCCTGAATTCCTAATTGTGTGGCTCCAGG 3'
The first primer, which hybridizes to the non-coding strand, corresponds to
the 5'
portion of the PTP-1B coding sequence and encodes a BamH I restriction site
upstream of the initiation codon, to facilitate cloning. The second primer,
which
hybridizes to the coding strand, corresponds to the 3' portion of the PTB-1 B
fragment
of interest, and encodes a stop codon and an EcoR I restriction site
downstream from
the stop codon.
A 100 ~.1 PCR reaction mixture containing approx. 1 ug of the human
placental cDNA library, 0.2 mM of each dNTP, 30 uM of each primer, 1 x
Amplitaq
DNA polymerase buffer (Perkin-Elmer, Norwalk CT), and 5 units Amplitaq DNA
polyrnerase (Perkin-Elmer} was denatured at 94~C for 5 minutes and then
subjected to
25 cycles of amplification as follows: 1 ) 94~C denaturation for 1 minute; 2)
55'C
annealing for 1 minute; and 3) 72~C primer extension for 1 minute.
The PCR reaction product {992 bp) was digested with BamH I and EcoR I
(New England Biolabs, Beverly MA) to yield a 975 by product encoding the 321
amino acid PTP-1 B protein fragment, and having "sticky ends" to facilitate
cloning.

B. Production of a PTP-1B expression vector.
The 975 by PTP-1B partial cDNA was purified by agarose gel electrophoresis
and ligated into a BamH IlEcoR I-digested pGEX-3X plasmid vector (Pharmacia,
_ Piscataway, NJ). The pGEX vector is designed to produce a fusion of
glutathione-S-
transferase (GST) to a protein encoded by another DNA fragment inserted into
the
vector's cloning site. Complete sequencing of the insert of the resultant
plasmid,
designated pGEX-3X-PTP-1 B, confirmed the identity of the PTP-1 B cDNA, and
insertion in the proper orientation and reading frame.
C. Expression and Purification of GST/PTP1B fusion protein.
E. coli strain DHSa (Gibco-BRL) was transformed with plasmid pGEX-3X-
PTP-IB following the supplier's transformation protocol and grown at 37~C with
vigorous shaking in Luria-Bertani broth supplemented with 100 ug/ml
ampicillin.
When the cultures reached an O.D.6oo of 0.7-1, production of the GST/PTP-IB
fusion
protein was induced with 0.1 mM IPTG (Isopropyl b-D-Thiogalactoside). After 3
additional hours of culturing at 37~C, the bacteria were pelleted by
centrifugation.
The bacterial pellet was resuspended in IOx (w/v) lysis buffer consisting of
1 ?.5 mM HEPES, 2 mM EDTA, pH 7.0, 15 mM b-mercaptoethanol (bME) and 1 mM
PMSF. The lysate was sonicated (on ice) until slight clearing was observed
(approx.
three min.) and then centrifuged at 10,000 revolutions per minute (RPM) for 10
min.
The supernatant was diluted 1:4 with buffer A (25 mM HEPES, pH 7.0, and 15 mM
bME).
Primary purification was achieved using a S ml Hi-Trap pre-packed Q column
(Pharmacia). After loading the diluted supernatant onto the column, the column
was
washed with 10 bed volumes of buffer A. The GST/PTP-1 B fusion protein was
then
eluted using a linear gradient of Buffer A and Buffer B (buffer A + 1 M NaCI).
Eluted fractions containing protein were identified by SDS-PAGE and Coomassie
Blue staining (Pharmacia PhastSystem), and fractions containing PTP-1 B
activity
were identified using the PTP-1 B activity assay described below. Elution of
the
fusion protein occurred at about 30% Buffer B.


CA 02275610 1999-06-15
WO 98/27065 PCT/I1S96/20508
Fractions containing PTPase activity were pooled, diluted 1:4 with NET buffer
(20 mM Tris, pH 8.8, 100 mM NaCI, 1 mM EDTA and 15 mM bME), and loaded
onto a 10 ml GST-Sepharose 4B column (Pharmacia). After loading, the column
was
washed first with 3 bed volumes of NET buffer + 1 % NP40 (Sigma Chemical Co.,
St.
Louis, MO), then with NET buffer until O.D. at 280 nm was basal. The GST/PTP-
1B
fusion protein was eluted from the column using 10 mM glutathione in 33 mM
Tris,
pH 8Ø Elution of proteins was monitored at O.D.2go and fractions were
assayed for
activity and run on SDS-PAGE as described above. PTP-1B fusion protein eluted
after approx. 4-5 minutes (flow rate lml/min.).
The GST/PTP-1B-containing fractions from the GST-Sepharose 4B
purification were pooled, concentrated into a final storage buffer (0.2 M
NaCI, 25
mM HEPES, 1 mM EDTA, and 5 mM DTT, pH 7.0) using a 1 ml Hi-Trap Q column
(pre-packed, Pharmacia), and stored at -80~C (final concentration of 0.52
mg/ml).
The foregoing procedure yielded approximately Smg of PTP-1B fusion protein per
500 ml of cultured cells, purified to substantial homogeneity as assessed by
SDS-
PAGE.
Assay of PTP-1B Activity.
PTP-1B enzymatic activity of samples was assayed in microtiter plates as
follows.
The protein concentration of the PTP-1 B enzyme preparation was determined
using the Bio-Rad Protein Assay kit (Bio-Rad, Hercules CA). An aliquot from
each
sample was taken and diluted to 2 mg protein/ml using activity assay buffer (
100 mM
Sodium Acetate, pH 6.0, 1 mM EDTA, 0.1 % TX-100 (International
Biotechnologies,
Inc.) and 15 mM bME) to form a PTP-1B stock solution.
A 100 ul reaction mixture was prepared containing 10 ul of the PTP-1B stock
solution, 10 ul of 9 mM p-nitrophenylphosphate ((pNPP), Sigma Chemical Co.,
St.
Louis MO), and 80 ul of activity assay buffer ( 100 mM sodium acetate, pH 6.0,
1 mM
EDTA, 0.1% Triton X-100, 15 mM bME). Reactions were mixed gently and
incubated at 3 TC for 60 minutes. Enzymatic cleavage of phosphate from pNPP (a

tyrosine phosphate analog) is marked by a colorimetric change in this
substrate. See,

Biophys. Res. Comm. , 194: 36-44 ( 1993 }; Zanke et al. , Eur. J. Immunol.,
22: 23 5-3 9
( 1992).
Reactions were stopped by addition of 10 ul of a 0.5 M NaOH/50% EtOH
solution. To determine the enzymatic activity, absorbance readings of the
reactions
were measured at 405 nm using a Molecular Devices Thermomax Plate Reader
(Memo Park CA).
CD45 Gene Cloning and Protein Purification
The following procedure was conducted for recombinant production and
purification of protein tyrosine phosphatase CD45, for use as a substrate in
PTPase
inhibition assays.
A. Production of aCD45 cDNA, and production of a CD45 expression vector.
A human cDNA library was synthesized from RNA isolated from the human
Jurkat cell line, as described above for PTP-1B
CD45 cDNA was amplified, using polymerase chain reaction (PCR), from the
cDNAs synthesized above. Two PCR primers were synthesized to amplify the
coding
sequence of CD45. The primers had the following respective sequences:
CD45 (5') (SEQ ID NO: 3)
5'CTACATCCCGGGATGTCCTGCAATTTAGATG3'
CD45 (3') (SEQ ID NO: 4)
5'CATTTATGTCCCGGGCTATGAACCTTGAT3'
The first primer corresponds to the 5' portion of the CD45 coding sequence and
encodes a Sma I restriction site upstream of the initiation codon, to
facilitate cloning.


CA 02275610 1999-06-15
WO 98/27065 PCT/US96/20508
92
The second primer corresponds to the 3' portion of the CD45 sequence, and
encodes a
stop codon and a Sma I restriction site downstream from the stop codon.
The PCR reaction product ( 2127 bp) was digested with Sma I (New England
Biolabs, Beverly MA) to yield a 2110 by product. The pET24C plasmid vector
(Novagen, Inc., Madison WI) was digested with the BamH I restriction enzyme,
and
the "sticky" ends were filled using T4 DNA polymerise according to the
manufacturer's instructions (New England Biolabs, Beverly MA); the resulting
plasmid DNA was ligated to Sma I-digested CD45 PCR product. The pET24C vector
is designed to produce high levels of the protein encoded by cDNA inserted
into the
vector's cloning site (CD45), in bacterial hosts. Complete sequencing of the
insert of
the resultant plasmid, designated pET24C-CD45, confirmed the identity of the
CD45
cDNA, and insertion in the proper orientation and reading frame.
C. Expression and Purification of CD45 protein.
E. toll strain DHSa (Gibco-BRL) was transformed with pET24C-CD45
following the supplier's transformation protocol, plated onto Luria-Bertani
agar plates
supplemented with 30 ug/ml kanamycin and grown overnight at 37~C. A single
bacterial colony was transferred into 50 mls Luria-Bertani broth supplemented
with
30 ug/ml kanamycin and grown overnight with vigorous shaking. This overnight
culture was split into two equal parts, and added to 2L Luria-Bertani broth
supplemented with SO ug/ml kanamycin. When the cultures reached an O.D.6oo of
1,
production of the recombinant CD45 protein was induced with 0.1 mM IPTG
(Isopropyl b-D-Thiogalactoside). After 5 additional hours of culturing at
37~C, the
bacteria were pelleted by centrifugation.
The bacterial pellet (approximately S grams) was resuspended in Z Ox (w/v)
lysis buffer consisting of 12.5 mM HEPES, 2 mM EDTA, pH 7.0, 15 mM bME and 1
mM PMSF. The lysate was sonicated (on ice) until slight clearing was observed
(approx. three min.) and then centrifuged at 10,000 revolutions per minute
(RPM) for
min. The supernatant was filtered through 1 mm Wattman filter paper, and 9.7
grams (i. e., 194 grams/L) of ammonium sulfate were added to the solution on
ice to


CA 02275610 1999-06-15
WD 98127065 PCT/US96I20508
93
precipitate soluble proteins. After a 1 hour incubation on ice, the lysate was
spun at
10,000 RPM for 30 min. at 4 C; supernatant was removed, and an additional 7.6
grams (i.e., 151 grams/L) of ammonium sulfate were added. The resulting pellet
was
resuspended in 3 mls of buffer B (33 mM imidazole-HCl pH 8.0, 2mM EDTA, 10
mM bME, 0.002% PMSF) and stored on ice. After another 1 hour incubation on
ice,
the spin supernatant with ammonium sulfate was spun again at 10,000 RPM for 30
mins at 4 C. The resulting pellet from the second centrifugation was
resuspended in 2
mls of buffer B. The two pellet solutions were pooled and dialyzed overnight
against
buffer B.
Secondary purification was achieved using a Mono-Q column. (Pharmacia).
After loading the diluted supernatant onto the column, the column was washed
with
bed volumes of buffer B. The recombinant CD45 protein was then eluted using a
linear gradient of Buffer B and Buffer C (buffer B + 1 M NaCI). Eluted
fractions
containing protein were identified by SDS-PAGE and Coomassie Blue staining
(Pharmacia PhastSystem), and fractions containing CD45 activity were
identified
using the CD45 activity assay described below.
The CD45-containing fractions from the MonoQ column purification were
pooled and stored at 4 C.
Assay of CD45 Activity.
CD45 enzymatic activity of samples was assayed in microtiter plates as
follows.
A 100 ul reaction mixture was prepared containing 10 ul of the CD45 stock
solution, 10 ul of 9.3 mM p-nitrophenylphosphate ((pNPP), Sigma Chemical Co.,
St.
Louis MO), and 80 ul of activity assay buffer ( 100 mM sodium acetate, pH 6.0,
1 mM
EDTA, 0.1% Triton X-100, 15 mM bME). Reactions were mixed gently and
incubated at 37~C for 60 minutes. Reactions were stopped by addition of 10 ul
of a
0.5 M NaOH/50% EtOH solution. To determine the enzymatic activity, absorbance
readings of the reactions were measured at 405 nm using a Molecular Devices
Thermomax Plate Reader (Menlo Park CA).

In vitro PTPase Inhibition Assay
The ability of the compounds of the present invention, such as the cinnamic
acid derivative compounds of Example 2, to inhibit the PTPase activity of PTP-
1 B,
CD45, PTP-1 C, and PTPa was determined using modifications of the PTP-1 B and
CD45 activity assays described in Examples 3 and 4.
First, 0.001 mmol of the cinnamic acid derivative (or other PTPase inhibitor
compound) was dissolved in 100 ul of DMSO to create a 10 mM stock solution.
The
mM stock solution was used to add varying concentrations (100 uM, 33 uM, 10
uM, 3 uM, 1 uM, 0.3 uM, 0.1 uM, 0.03 uM, 0.01 uM or 0.003 uM) of the inhibitor
compound to a series of otherwise identical PTPase activity assay reactions (
100 ul
final volume in microtiter wells). Thus, each 100 ul reaction contained 10 ul
PTPase
enzyme stock solution (final phosphatase concentration of approximately 20
ng/well),
70 ul activity assay buffer, 10 ul pNPP stock solution (final pNPP
concentration of .9
mM for PTP-1B assay, 0.93 mM for CD45 assay, 0.5 mM for PTPa assay, and 8 mM
for PTP-1 C assay), and I 0 ul of the diluted inhibitor compound in DMSO.
Assay
buffers contained: for CD45 and PTP-IB assays, 100 mM sodium acetate at pH
6.0,
1 mM EDTA, 0.1 % Triton X-100, and 15 mM bME; for PTP-1 C assays, 100 mM
sodium acetate at pH 5.5, 0.1 % B SA, and 15 mM bME; for PTP a assays, 100 mM
sodium acetate at pH 5.25, 0.1% BSA, and 15 mM bME. Purified phosphatase was
added to the reaction mixtures to begin the reactions; the reactions were
incubated at
37C for 60 min. (for PTP-1 B and CD45 assays) or at 27 C for 60 min. (for PTP-
1 C
and PTPa assays), stopped, and colorimetrically analyzed as described above.
As
positive and negative controls, reactions were performed containing 10 ul DMSO
with no inhibitor compound or containing the known PTPase inhibitors vanadate
(final concentration .5 mM; for PTP- I B and CD45 assays ) or ammonium
molybdate
(final concentration i mM; for PTP-1 C and PTPa assays) substituted for the
inhibitor
compound of the invention.
The concentration of inhibitor compound required to inhibit 50% of the
PTPase activity (IC50) was determined as follows. First, absorbance readings
from


CA 02275610 1999-06-15
WO 98/27065 PCT/US96/20508
the negative control reactions were treated as a baseline and subtracted from
the
absorbance readings of the experimental reactions. Then, for each reaction, a
percent
inhibition was calculated using the following formula:
100 X [ 1 - ( O.D.4os reaction / O.D.4os DMSO) ]
For each inhibitor compound tested, an IC50 concentration was calculated from
a
best-fit computer analysis of the calculated percent inhibition for the vari
ous dilutions
of the compound.
Inhibitor compounds having an IC50 less than 10 uM (and optimally less than
SuM) for a particular PTPase were scored as highly effective inhibitors of
that PTPase
enzyme, and are preferred inhibitors of the present invention.

As it will be apparent to those persons skilled in the art, the foregoing
biological data is not absolute and will vary according to many factors such
as assay
conditions and the like.

The compounds of the present invention have asymmetric centeis and may
occur as racemates, racemic mixtures, and as individual enantiomers or
diastereoisomers, with all isomeric forms being included in the present
invention as
well as mixtures thereof.
Pharmaceutically acceptable salts of the compounds of Formula (A 1 ) thru
(A 11 ) where a basic or acidic group is present in the structure, are also
included
within the scope of this invention. When an acidic substituent is present,
such as -
COOH~ there can be formed the ammonium, sodium, potassium, calcium salt, and
the
like, for use as the dosage form. When a basic group is present, such as amino
or a
basic heteroaryl radical, such as pyridyl, an acidic salt, such as
hydrochloride,
hydrobromide, acetate, maleate, pamoate, methanesulfonate, p-toluenesulfonate,
and
the like, can be used as the dosage form.
Also, in the case of the -COOH being present, pharmaceutically acceptable
esters can be employed, e.g., methyl, tert-butyl, pivaloyloxymethyl, and the
like, and
those esters known in the art for modifying solubility or hydrolysis
characteristics for
use as sustained release or prodrug formulations.
In addition, some of the compounds of the instant invention may form solvates
with water or common organic solvents. Such solvates are encompassed within
the
scope of the invention.
The term "therapeutically effective amount" shall mean that amount of drug or
pharmaceutical agent that will elicit the biological or medical response of a
tissue,
system, animal, or human that is being sought by a researcher, veterinarian,
medical
doctor or other clinician. Generally, a daily dose of about O.Smg/Kg to
100mg/Kg
body weight in divided doses is suggested to treat PTPase related diseases.
Such
dosage has to be individualized by the clinician.
The present invention also has the objective of providing suitable topical,
oral,
and parenteral pharmaceutical formulations for use in the novel methods of
treatment
of the present invention. The compounds of the present invention may be
administered orally as tablets, aqueous or oily suspensions, lozenges,
troches,


CA 02275610 1999-06-15
WO 98/27065 PCT/tJS96/20508
100
powders, granules, emulsions, capsules, syrups or elixirs. The composition for
oral
use may contain one or more agents selected from the group of sweetening
agents,
flavouring agents, colouring agents and preserving agents in order to produce
pharmaceutically elegant and palatable preparations. The tablets contain the
acting
ingredient in admixture with non-toxic pharmaceutically acceptable excipients
which
are suitable for the manufacture of tablets. These excipients may be, for
example, ( 1 )
inert diluents , such as calcium carbonate, lactose, calcium phosphate or
sodium
phosphate; (2) granulating and disintegrating agents, such as corn starch or
alginic
acid; (3) binding agents, such as starch, gelatin or acacia; and (4)
lubricating agents,
such as magnesium stearate, stearic acid or talc. These tablets may be
uncoated or
coated by known techniques to delay disintegration and absorption in the
gastrointestinal tract and thereby provide a sustained action over a longer
period. For
example, a time delay material such as glyceryl monostearate or glyceryl
distearate
may be employed. Coating may also be performed using techniques described in
the
U.S. Patent Nos. 4,256,108; 4,160,452; and 4,265,874 to form osmotic
therapeutic
tablets for control release.
Formulations for oral use may be in the form of hard gelatin capsules wherein
the active ingredient is mixed with an inert solid diluent, for example,
calcium
carbonate, calcium phosphate or kaolin. They may also be in the form of soft
gelatin
capsules wherein the active ingredient is mixed with water or an oil medium,
such as
peanut oil, liquid paraffin or olive oil.
Aqueous suspensions normally contain the active materials in admixture with
excipients suitable for the manufacture of aqueous suspension. Such expicients
may
be: ( 1 ) suspending agent such as sodium carboxymethyl cellulose, methyl
cellulose, hydroxypropylmethylcellulose, sodium alginate,
polyvinylpyrrolidone, gum
tragacanth and gum acacia;
(2) dispersing or wetting agents which may be (a) naturally occurring
phosphatide such as lecithin; (b) a condensation product of an alkylene oxide
with a
fatty acid, for example, polyoxyethylene stearate; (c) a condensation product
of


CA 02275610 1999-06-15
WO 98/27065 PCTIUS96/20508
101
ethylene oxide with a long chain aliphatic alcohol, for example,
heptadecaethylenoxycetanol; (d) a condensation product of ethylene oxide with
a
partial ester derived from a fatty acid and hexitol such as polyoxyethylene
sorbitol
monooleate, or (e) a condensation product of ethylene oxide with a partial
ester
derived from fatty acids and hexitol anhydrides, for example polyoxyethylene
sorbitan monooleate.
The pharmaceutical compositions may be in the form of a sterile injectable
aqueous or oleagenous suspension. This suspension may be formulated according
to
known methods using those suitable dispersing or wetting agents and suspending
agents which have been mentioned above. The sterile injectable preparation may
also
a sterile injectable solution or suspension in a non-toxic parenterally-
acceptable
diluent or solvent, for example, as a solution in 1,3-butanediol. Among the
acceptable
vehicles and solvents that may be employed are water, Ringer's solution, and
isotonic
sodium chloride solution. In addition, sterile, fixed oils are conventionally
employed
as a solvent or suspending medium. For this purpose, any bland fixed oil may
be
employed including synthetic mono- or diglycerides. In addition, fatty acids
such as
oleic acid find use in the preparation of injectables.
Compounds of Formula (A 1 ) thru (A 11 ) may also be administered in the form
of suppositories for rectal administration of the drug. These compositions can
be
prepared by mixing the drug with a suitable non-irritating excipient which is
solid at
ordinary temperature but liquid at the rectal temperature and will therefore
melt in the
rectum to release the drug. Such materials are cocoa butter and polyethylene
glycols.
The compounds of the present invention may also be administered in the form
of liposome delivery systems, such as small unilamellar vesicles, large
unilamellar
vesicles, and multilamellar vesicles. Liposomes can be formed from a variety
of
phospholipids, such as cholesterol, stearylamine, or phosphatidylcholines.
For topical use, creams, ointments, jellies, solutions or suspensions, etc.,
containing the compounds of Formula (A1) thru (A11) are employed.
