TITLE
4,4-DISUBSTITUTED-3,4-DIHYDRO-2(1H)-QUINAZOLINONES USEFUL AS
HIV REVERSE TRANSCRIPTASE INHIBITORS
FIELD OF THE INVENTION
This invention relates generally to 4,4-disubstituted-
3,4-dihydro-2(1H)-quinazolinones which are useful as
inhibitors of HIV reverse transcriptase, pharmaceutical
compositions and diagnostic kits comprising the same, methods
of using the same for treating viral infection or as assay
standards or reagents, and intermediates and processes for
making the same.
BACKGROUND OF THE INVENTION
Two distinct retroviruses, human immunodeficiency virus
(HIV) type-1 (HIV-1) or type-2 (HIV-2), have been
etiologically linked to the immunosuppressive disease,
acquired immunodeficiency syndrome (AIDS). HIV seropositive
individuals are initially asymptomatic but typically develop
AIDS related complex (ARC) followed by AIDS. Affected
individuals exhibit severe immunosuppression which
predisposes them to debilitating and ultimately fatal
opportunistic infections.
The disease AIDS is the end result of an HIV-1 or HIV-2
virus following its own complex life cycle. The virion life
cycle begins with the virion attaching itself to the host
human T-4 lymphocyte immune cell through the bonding of a
glycoprotein on the surface of the virion's protective coat
with the CD4 glycoprotein on the lymphocyte cell. Once
attached, the virion sheds its giycoprotein coat, penetrates
into the membrane of the host cell, and uncoats its RNA. The
virion enzyme, reverse transcriptase, directs the process of
transcribing the RNA into single-stranded DNA. The viral RNA
is degraded and a second DNA strand is created. The now
double-stranded DNA is integrated into the human cell's genes
and those genes are used for virus reproduction.
CA 02284996 1999-09-27
WO 98/45276 PCT/US98/06733
At this point, RNA polymerise transcribes the integrated
DNA into viral RNA. The viral RNA is translated into the
precursor gag-pot fusion polyprotein. The polyprotein is
then cleaved by the HIV protease enzyme to yield the mature
viral proteins. Thus, HIV protease is responsible for
regulating a cascade of cleavage events that lead to the
virus particle's maturing into a virus that is capable of
full infectivity.
The typical human immune system response, killing the
invading virion, is taxed because the virus infects and kills
the immune system's T cells. In addition, viral reverse
transcriptase, the enzyme used in making a new virion
particle, is not very specific, and causes transcription
mistakes that result in continually changed glycoproteins on
the surface of the viral protective coat. This lack of
specificity decreases the immune system's effectiveness
because antibodies specifically produced against one
glycoprotein may be useless against another, hence reducing
the number of antibodies available to fight the virus. The
virus continues to reproduce while the immune response system
continues to weaken. Eventually, the HIV largely holds free
reign over the body's immune system, allowing opportunistic
infections to set in and without the administration of
antiviral agents, immunomodulators, or both, death may
result.
There are at least three critical points in the virus's
life cycle which have been identified as possible targets for
antiviral drugs: (1) the initial attachment of the virion to
the T-4 lymphocyte or macrophage site, (2) the transcription
of viral RNA to viral DNA (reverse transcriptase, RT), and
(3) the processing of gag-pol protein by HIV protease.
Inhibition.of the virus at the second critical point,
the viral RNA to viral DNA transcription process, has
provided a number of the current therapies used in treading
AIDS. This transcription must occur for the virion to
reproduce because the virion's genes are encoded in RNA and
the host cell reads only DNA. By introducing drugs that
2
CA 02284996 1999-09-27
WO 98/45276 PCTIUS98/06733
block the reverse transcriptase from completing the formation
of viral DNA, HIV-1 replication can be stopped.
A number of compounds that interfere with viral
replication have been developed to treat AIDS. For example,
nucleoside analogs, such as 3'-azido-3'-deoxythymidine (AZT),
. 2',3'-dideoxycytidine (ddC), 2',3'-dideoxythymidinene (d4T),
2',3'-dideoxyinosine (ddI), and 2',3'-dideoxy-3'-thia-
cytidine (3TC) have been shown to be relatively effective in
halting HIV replication at the reverse transcriptase (RT)
stage.
An active area of research is in the discovery of non-
nucleoside HIV reverse transcriptase inhibitors. As an
example, it has been found that certain benzoxazinones and
quinazolinones are active in the inhibition of HIV reverse
transcriptase, the prevention or treatment of infection by
HIV and the treatment of AIDS.

Even with the current success of reverse transcriptase
inhibitors, it has been found that HIV patients can become
resistant to a single inhibitor. Thus, it is desirable to
develop additional inhibitors to further combat HIV
infection.

The phrase "pharmaceutically acceptable" is employed
herein to refer to those compounds, materials, compositions,
and/or dosage forms which are, within the scope of sound
medical judgment, suitable for use in contact with the
tissues of human beings and animals without excessive
toxicity, irritation, allergic response, or other problem or
complication commensurate with a reasonable benefit/risk
ratio.
"Prodrugs" are intended to include any covalently bonded
carriers which release the active parent drug according to
formula (I) or other formulas or compounds of the present
invention in vivo when such prodrug is administered to a
mammalian subject. Prodrugs of a compound of the present
invention, for example formula (I), are prepared by modifying
functional groups present in the compound in such a way that
the modifications are cleaved, either in routine manipulation
or in vivo, to the parent compound. Prodrugs include
compounds of the present invention wherein the hydroxy or
amino group is bonded to any group that, when the prodrug is
administered to a mammalian subject, cleaves to form a free
hydroxyl or free amino, respectively. Examples of prodrugs
include, but are not limited to, acetate, forrnate and
benzoate derivatives of alcohol and amine functional groups
in the compounds of the present invention, and the like.
"Stable compound" and "stable structure" are meant to
indicate a compound that is sufficiently robust to survive
isolation to a useful degree of purity from a reaction
mixture, and formulation into an efficacious therapeutic
agent. Only stable compounds are contempleted by the present
invention.
"Substituted" is intended to indicate that one or more
hydrogens on the atom indicated in the expression using
"substituted" is replaced with a selection from the indicated
group(s), provided that the indicated atom's normal valency
is not exceeded, and that the substitution results in a
stable compound. When a substituent is keto (i.e., =O)
group, then 2 hydrogens on the atom are replaced.

"Therapeutically effective amount" is intended to
include an amount of a compound of the present invention or
an amount of the combination of compounds claimed effective
to inhibit HIV infection or treat the symptoms of HIV
infection in a host. The combination of compounds is
preferably a synergistic combination. Synergy, as described
for example by Chou and Talalay, Adv. Enzyme Regul. 22:27-55
(1984), occurs when the effect (in this case, inhibition of
HIV replication) of the compounds when administered in
combination is greater than the additive effect of the
compounds when administered alone as a single agent. In
general, a synergistic effect is most clearly demonstrated at
suboptimal concentrations of the compounds. Synergy can be
in terms of lower cytotoxicity, increased antiviral effect,
or some other beneficial effect of the combination compared
with the individual components.

which may be prepared by the methods desribed in Schemes 1
and 2, is treated with trimethylsilyl isocyanate in dry
tetrahydofuran in the presence of dimethylaminopyridine
followed by tetrabutylammonium fluoride to give the hydroxy-
S urea 2. The hydroxy-urea 2 is then dehydrated with a
dehydrating agent such as 4~1 molecular sieves in refluxing
toluene or xylenes to give the ketimine 3. A substituted
acetylenic R2 group is added by treating the ketimine 3 with
a lithium acetylide, which is prepared in a separate vessel
by reacting the corresponding substituted acetylene with n-
butyllithium in dry tetrahydrofuran, to give the 4,4-
disubstituted 3,4-dihydro-2(1H)-quinazolinone 4_, a compound
of formula I. The acetylenic bond of the compound 4 may be
reduced, e.g., by catalytic hydrogenation, to give the
corresponding alkenyl group (not shown) or the saturated
compound 5_.
Other R2 groups may also be introduced by directly
reacting the imine 3_ with a lithiate RZLi or a Grignard
reagent R2MgX in the presence or absence of Lewis acid
catalyst, such as BF3 etherate. See also Huffman et al, J.

In certain instances, one enantiomer of a compound of
Formula I or II may display superior activity compared with
the other. inlhen required, separation of the racemic material
can be achieved by HPLC using a chiral column as exemplified
in Examples 27-34 (Scheme 4) or by a resolution using a
resolving agent such as camphonic chloride as in Thomas J.
Tucker, et al, J. Med. Chem. 1994, 3 7, 2437-2444. A chiral
compound of Formula I may also be directly synthesized using
a chiral catalyst or a chiral ligand, e.g. Mark A. Huffman,
et al, J. Org. Chem. 1995, 60, 1590-1594.

Step 1. Synthesis of II-a from I-a.
To a solution of compound I-a (4.55 g, 20.2 mmol) in
anhydrous THF (40 mL) was added dimethylaminopyridine (0.25
g, 2.02 mmol) and trimethylsilyl isocyanate (6.05 g, 7.11 mL,
52.5 mmol). The mixture was stirred at room temperature for
26
CA 02284996 1999-09-27
WO 98/45276 PCT/US98106733
approximately 16 hours, then tetrabutylammonium fluoride (21
mL of 1 M solution in THF) was added. The thick slurry was
diluted with additional THF (20 mL) and stirred at room
temperature for 0.5 hours. The THF was removed under reduced
S pressure, the residue was taken up in EtOAc (100 mL) and
washed sequentially with I N HC1 (70 mL), saturated aqueous
NaHC03 (70 mL) and saturated aqueous NaCl (50 mL). The
organic phase was dried over MgS04, filtered and concentrated
under reduced pressure to afford a light yellow solid. The
yellow color was removed upon trituration with hexanes to
afford IIa (5.09 g, 94~) as a white solid: 1H NMR (300 MHz,
acetone-ds) 8 9.06 (br s, 1 H), 7.48 (s, 1 H), 7.40 (br s, 1
H), 7.34 (dd, J = 8.8, 2.6 Hz, 1 H), 6.97 (d, J = 8.8 Hz, 1

Step 2. Synthesis of III-a from II-a.
A suspension of II-a (5.09 g, 19.1 mmol) in toluene (150
mL) containing 4 ~ molecular sieves (approximately 100 mg)
was heated at reflex for 16 hours. The resulting clear
yellow solution was cooled to room temperature, the
precipitated solids were dissolved in acetone and the
molecular sieves were removed by vacuum filtration. The
filtrate was concentrated under reduced pressure, and
triturated with hexanes to afford III-a (4.25 g, 89g) as a
yellow solid: 1H NN~ (300 N~iz, acetone-d6) 8 7.86-7.82 (m, 2
H), 7.61 (d, J = 8.8 Hz, 1 H); 19F NMR (282 MHz, acetone-d6) $

Step 3. Synthesis of IV-a from IIIa.
A solution of cyclopropylacetylene (13.0 mL of 30 wt~
solution in toluene/THF/hexanes, 59.0 mmol) in anhydrous THF
(118 mL) was cooled to -78 °C, treated with n-BuLi (32.8 mL
of 1.6 M solution in hexanes, 52.4 mmol), warmed to 0 °C in
an ice bath, and aged for 0.5 h. To a solution of III-a

added the lithium acetylide over approximately 10 minutes.
To this was added boron trifluoride etherate (0.89 g, 0.80
mL, 6.28 rnmol), followed by removal of the cooling bath. The
reaction was allowed to reach room temperature and stirred at
room temperature for 4 hours before quenching with 1 M citric
acid (100 mL). The mixture was concentrated under reduced
pressure to 1/2 original volume, diluted with EtOAc (200 mL),
the aqueous phase was removed and the organic phase was
sequentially washed with saturated aqueous NaHC03 (100 mL),
and saturated aqueous NaCl (100 mL). The organic phase was
dried over MgS04, filtered and concentrated under reduced
pressure. The crude material was purified by flash
chromatography (3~ MeOH/CH2C12) to afford a thick yellow oil

Preparation of (+)-4-E-Cyclopropylethenyl-5,6
difluoro-4-trifluoromethyl-3,4-dihydro-2(1H)
guinazolinone
To a solution of XII-b (200 mg, 0.632 mmol) in anhyd.
THF (1.3 mL) at rt was added a solution of lithium aluminium
hydride (1.3 mL of 1.0 M solution in THF). The resulting
mixture was stirred at rt overnight. The reaction was
quenched by addition of 10~ NaOH (3 mL) and water (3 mL).
The mixture was diluted with EtOAc (30 mL) and the phases
were separated. The organic phase was washed with sat. aq.
NaCl, dried over MgS04, filtered and concentrated. The title
compound was purified by regular phase HPLC (41.4 mm Rainin
Dynamaxt~ column using 60 ~ silica): 2.5~ MeOH/CH2C12 for 24
min, increase to 30$ MeOH/CH2C12 over 4 min, 30~ MeOH/CHZC12

HIV RNA Assav
DNA Plasmids and in vitro RNA transcri,~ts:
Plasmid pDAB 72 containing both gag and pol sequences of
BH10 (bp 113-1816) cloned into PTZ 19R was prepared according
to Erickson-Viitanen et al. AIDS Research arid Human
Retroviruses 1989, 5, 577. The plasmid was linearized with
Bam HI prior to the generation of in vitro RNA transcripts
using the Riboprobe Gemini system II kit (Promega) with T?
RNA polymerase. Synthesized RNA was purified by treatment
with RNase free DNAse (Promega), phenol-chloroform
extraction, and ethanol precipitation. RNA transcripts were
dissolved in water, and stored at -70°C. The concentration
of RNA was determined from the A260
2S Probes
Biotinylated capture probes were purified by HPLC after
synthesis on an Applied Biosystems (Foster City, CA) DNA
synthesizer by addition of biotin to the 5' terminal end of
the oligonucleotide, using the biotin-phosphoramidite reagent
of Cocuzza, Tet. Lett. 1989, 30, 6287. The gag biotinylated
capture probe (5-biotin-CTAGCTCCCTGCTTGCCCATACTA 3') was
complementary to nucleotides 889-912 of HXB2 and the pol
biotinylated capture probe (S'-biotin -CCCTATCATTTTTGGTTTCCAT
3' ) was complementary to nucleotides 2374-2395 of HXB2.
Alkaline phosphatase conjugated oligonucleotides used as
reporter probes were prepared by Syngene (San Diego, CA.).
The pol reporter probe (5' CTGTCTTACTTTGATAAAACCTC 3') was
complementary to nucleotides 2403-2425 of HXB2. The gag
114
r ,.
CA 02284996 1999-09-27
WO 98/45276 PCT/US98/06733
reporter probe (5' CCCAGTATTTGTCTACAGCCTTCT 3') was
complementary to nucleotides 950-973 of HXB2. All nucleotide
positions are those of the GenBank Genetic Sequence Data Bank
as accessed through the Genetics Computer Group Sequence
Analysis Software Package (Devereau Nucleic Acids Research
1984, 12, 387). The reporter probes were prepared as 0.5 ~1.M
stocks in 2 x SSC (0.3 M NaCl, 0.03 M sodium citrate), 0.05 M
Tris pH 8.8, 1 mg/mL BSA. The biotinylated capture probes
were prepared as 100 ~tM stocks in water.
Streptavidin coated pl es:
Streptavidin coated plates were obtained from Du Pont
Biotechnology Systems (Boston, MA).
c~e7 ~ s and virus stocks:
MT-2 and MT-4 cells were maintained in RPMI 1640
supplemented with 5~ fetal calf serum (FCS) for MT-2 cells or
10~ FCS for MT-4 cells, 2 mM z-glutamine and 50 ~1g/mL
gentamycin, all from Gibco. HIV-1 RF was propagated in MT-4
cells in the same medium. Virus stocks were prepared
approximately 10 days after acute infection of MT-4 cells and
stored as aliquots at -70°C. Infectious titers of HIV-1(RF)
stocks were 1-3 x 107 PFU (plaque forming units)/mL as
measured by plaque assay on MT-2 cells (see below). Each
aliquot of virus stock used for infection was thawed only
once.
For evaluation of antiviral efficacy, cells to be
infected were subcultured one day prior to infection. On the
day of infection, cells were resuspended at 5 x 105 cells/mL
in RPMI 1640, 5~ FCS for bulk infections or at 2 x 106/mL in
Dulbecco's modified Eagles medium with 5~ FCS for infection
in microtiter plates. Virus was added and culture continued
for 3 days at 37°C.
HIV RNA assav:
Cell lysates or purified RNA in 3 M or 5 M GED were
mixed with 5 M GED and capture probe to a final guanidinium
isothiocyanate concentration of 3 M and a final biotin
115
CA 02284996 1999-09-27
WO 98/45276 PCT/US98/06733
oligonucleotide concentration of 30 nM. Hybridization was
carried out in sealed U bottom 96 well tissue culture plates
(Nunc or Costar) for 16-20 hours at 37°C. RNA hybridization
reactions were diluted three-fold with deionized water to a
final guanidinium isothiocyanate concentration of 1 M and
aliquots (150 ~tL) were transferred to streptavidin coated
microtiter plates wells. Binding of capture probe and
capture probe-RNA hybrid to the immobilized streptavidin was
allowed to proceed for 2 hours at room temperature, after
which the plates were washed 6 times with DuPont ELISA plate
wash buffer (phosphate buffered saline(PBS), 0.05 Tween 20.)
A second hybridization of reporter probe to the in~unobilized
complex of capture probe and hybridized target RNA was
carried out in the washed streptavidin coated well by
addition of I20 ~.1 of a hybridization cocktail containing 4 X
SSC, 0.66 Triton X 100, 6.66 deionized formamide, 1 mg/mL
BSA and 5 nM reporter probe. After hybridization for one
hour at 37°C, the plate was again washed 6 times.
Immobilized alkaline phosphatase activity was detected by
addition of 100 N.L of 0.2 mM 4-methylumbelliferyl phosphate
(MUBP, JBL Scientific) in buffer 8(2.5 M diethanolamine pH 8.9
(JBL Scientific), 10 mM MgCl2, 5 mM zinc acetate dihydrate
and 5 mM N-hydroxyethyl-ethylene-diamine-triacetic acid).
The plates were incubated at 37°C. Fluorescence at 450 nM
was measured using a microplate fluorometer (Dynateck)
exciting at 365 nM.
Mi~rot~late based compound evaluation in HIV-1 infected MT-2
c 1 s:
Compounds to be evaluated were dissolved in DMSO and
diluted in culture medium to twice the highest concentration
to be tested and a maximum DMSO concentration of 2~. Further
three-fold serial dilutions of the compound in culture medium
were performed directly in U bottom microtiter plates (Nunc).
After compound dilution, MT-2 cells (SO N,L) were added to a
final concentration of 5 x 105 per mL (1 x 105 per well).
Cells were incubated with compounds for 30 minutes at 37°C in
a C02 incubator. For evaluation of antiviral potency, an
116
CA 02284996 1999-09-27
WO 98/45276 PCT/US98/06733
appropriate dilution of HIV-1 (RF) virus stock (50 ~,L) was
added to culture wells containing cells and dilutions of the
test compounds. The final volume in each well was 200 ~.L.
. Eight wells per plate were left uninfected with 50 ~1L of
medium added in place of virus, while eight wells were
infected in the absence of any antiviral compound. For
evaluation of compound toxicity, parallel plates were
cultured without virus infection.
After 3 days of culture at 37°C in a humidified chamber
inside a C02 incubator, all but 25 ~,L of medium/well was
removed from the HIV infected plates. Thirty seven ~.L of 5 M
GED containing biotinylated capture probe was added to the
settled cells and remaining medium in each well to a final
concentration of 3 M GED and 30 nM capture probe.
Hybridization of the capture probe to HIV RNA in the cell
lysate was carried out in the same microplate well used for
virus culture by sealing the plate with a plate sealer
(Costar), and incubating for 16-20 hrs in a 37°C incubator.
Distilled water was then added to each well to dilute the
hybridization reaction three-fold and 150 ~.L of this diluted
mixture was transferred to a streptavidin coated microtiter
plate. HIV RNA was quantitated as described above. A
standard curve, prepared by adding known amounts of pDAB 72
in vitro RNA transcript to wells containing lysed uninfected
cells, was run on each microtiter plate in order to determine
the amount of viral RNA made during the infection.
In order to standardize the virus inoculum used in the
evaluation of compounds for antiviral activity, dilutions of
virus were selected which resulted in an IC90 value
(concentration of compound required to reduce the HIV RNA
level by 90$) for dideoxycytidine (ddC) of 0.2 ~,g/mL. IC90
values of other antiviral compounds, both more and less
potent than ddC, were reproducible using several stocks of
HIV-1 (RF) when this procedure was followed. This
concentration of virus corresponded to -3 x 105 PFU (measured
by plaque assay on MT-2 cells) per assay well and typically
produced approximately 75~k of the maximum viral RNA level
achievable at any virus inoculum. For the HIV RNA assay,

ICgO values were determined from the percent reduction of net
signal (signal from infected cell samples minus signal from
uninfected cell samples) in the RNA assay relative to the net
signal from infected, untreated cells on the same culture
plate (average of eight wells). Valid performance of
individual infection and RNA assay tests was judged according
to three criteria. It was required that the virus infection
should result in an RNA assay signal equal to or greater than
the signal generated from 2 ng of pDAB 72 in vitro RNA
transcript. The IC9p for ddC, determined in each assay run,
should be between 0.1 and 0.3 E.tg/mL. Finally, the plateau
level of viral RNA produced by an effective reverse
transcriptase inhibitor should be less than 10~ of the level
achieved in an uninhibited infection. A compound was
considered active if its ICgQ was found to be less than 20~.tM.
For antiviral potency tests, all manipulations in
microtiter plates, following the initial addition of 2X
concentrated compound solution to a single row of wells, were
performed using a Perkin Elmer/Cetus ProPette.

Protein Binding and Mutant Resistance
In order to characterize NNRTI analogs for their
clinical efficacy potential the effect of plasma proteins on
antiviral potency and measurements of antiviral potency
against wild type and mutant variants of HIV which carry
amino acid changes in the known binding site for NNRTIs were
examined. The rationale for this testing strategy is two
fold:
1. Many drugs are extensively bound to plasma proteins.
Although the binding affinity for most drugs for the major
components of human plasma, namely, human serum albumin (HSA)
or alpha-1-acid glycoprotein (AAG), is low, these major
components are present in high concentration in the blood.
Only free or unbound drug is available to cross the infected
cell membrane for interaction with the target site (i.e.,
HIV-1 reverse transcriptase, HIV-1 RT?. Therefore, the
effect of added HSA+AAG on the antiviral potency in tissue
culture more closely reflects the potency of a given compound
118
CA 02284996 1999-09-27
WO 98/45276 PCT1US98/06733
in the clinical setting. The concentration of compound
required for 90~ inhibition of virus replication as measured
in a sensitive viral RNA-based detection method is designated
the IC90. The fold increase in apparent IC90 for test
compounds in the presence or added levels of HSA and AAG that
reflect in vivo concentrations (45 mg/ml HSA, 1 mg/ml AAG)
was then calculated. The lower the fold increase, the more
compound will be available to interact with the target site.
2. The combination of the high rate of virus
replication in the infected individual and the poor fidelity
of the viral RT results in the production of a quasi-species
or mixtures of HIV species in the infected individual. These
species will include a majority wild type species, but also
mutant variants of HIV and the proportion of a given mutant
will reflect its relative fitness and replication rate.
Because mutant variants including mutants with changes in the
amino acid sequence of the viral RT likely pre-exist in the
infected individual's quasi-species, the overall potency
observed in the clinical setting will reflect the ability of
a drug to inhibit not only wild type HIV-1, but mutant
variants as well. We thus have constructed, in a known
genetic background, mutant variants of HIV-1 which carry
amino acid substitutions at positions thought to be involved
in NNRTI binding, and measured the ability of test compounds
to inhibit replication of these mutant viruses. The
concentration of compound required for 90~ inhibition of
virus replication as measured in a sensitive viral RNA-based
detection method is designated the IC90. It is desirable to
have a compound which has high activity against a variety of
mutants.
Dosaae and Formulation '
The antiviral compounds of this invention can be
administered as treatment for viral infections by any means
that produces contact of the active agent with the agent's
site of action, i.e., the viral reverse transcriptase, in the
body of a mammal. They can be administered by any
conventional means available for use in conjunction with
119
CA 02284996 1999-09-27
WO 98/45276 PCT/US98/06733
pharmaceuticals, either as individual therapeutic agents or
in a combination of therapeutic agents. They can be
administered alone, but preferably are administered with a
pharmaceutical carrier selected on the basis of the chosen
route of administration and standard pharmaceutical practice.
The dosage administered will, of course, vary depending
upon known factors, such as the pharmacodynamic
characteristics of the particular agent and its mode and
route of administration; the age, health and weight of the
recipient; the nature and extent of the symptoms; the kind of
concurrent treatment; the frequency of treatment; and the
effect desired. A daily dosage of active ingredient can be
expected to be about 0.001 to about 1000 milligrams per
kilogram of body weight, with the preferred dose being about
0.1 to about 30 mg/kg.
Dosage forms of compositions suitable for administration
contain from about 1 mg to about 100 mg of active ingredient
per unit. In these pharmaceutical compositions the active
ingredient will ordinarily be present in an amount of about
0.5-95~ by weight based on the total weight of the
composition. The active ingredient can be administered
orally in solid dosage forms, such as capsules, tablets and
powders, or in liquid dosage forms, such as elixirs, syrups
and suspensions. It can also be administered parenterally,
in sterile liquid dosage forms.
Gelatin capsules contain the active ingredient and
powdered carriers, such as lactose, starch, cellulose
derivatives, magnesium stearate, stearic acid, and the like.
Similar diluents can be used to make compressed tablets.
Both tablets and capsules can be manufactured as sustained
release products to provide for continuous release of
medication over.a period of hours. Compressed tablets can be
sugar coated or film coated to mask any unpleasant taste and
protect the tablet from the atmosphere, or enteric coated for
selective disintegration in the gastrointestinal tract.
Liquid dosage forms for oral administration can contain
coloring and flavoring to increase patient acceptance.

In general, water, a suitable oil, saline, aqueous
dextrose (glucose), and related sugar solutions and glycols
such as propylene glycol or polyethylene glycols are suitable
carriers for parenteral solutions. Solutions for parenteral
S administration preferably contain a water soluble salt of the
active ingredient, suitable stabilizing agents, and if
necessary, buffer substances. Antioxidizing agents such as
sodium bisulfite, sodium sulfite, or ascorbic acid, either
alone or combined, are suitable stabilizing agents. Also
used are citric acid and its salts, and sodium EDTA. In
addition, parenteral solutions can contain preservatives,
such as benzalkonium chloride, methyl- or propyl-paraben and
chlorobutanol. Suitable pharmaceutical carriers are
described in Rernington's Pharmaceutical Sciences, supra, a
standard reference text in this field.
Useful pharmaceutical dosage-forms for administration of
the compounds of this invention can be illustrated as
follows:
Capsules
A large number of unit capsules can be prepared by
filling standard two-piece hard gelatin capsules each with
100 mg of powdered active ingredient, I50 mg of lactose, 50
mg of cellulose, and 6 mg magnesium stearic.
Soft Gelatin Capsules
A mixture of active ingredient in a digestible oil such
as soybean oil, cottonseed oil or olive oil can be prepared
and injected by means of a positive displacement pump into
gelatin to form soft gelatin capsules containing 100 mg of
the active ingredient. The capsules should then be washed
and dried.
T a
A large number of tablets can be prepared by
conventional procedures so that the dosage unit is 100 mg of
active ingredient, 0.2 mg of colloidal silicon dioxide, 5
milligrams of magnesium stearate, 275 mg of microcrystalline
121
CA 02284996 1999-09-27
WO 98/45276 PCT/US98/06733
cellulose, 11 mg of starch and 98.8 mg of lactose.
Appropriate coatings may be applied to increase palatability
or delay absorption.
Sust~ension
An aqueous suspension can be prepared for oral
administration so that each 5 mL contain 25 mg of finely
divided active ingredient, 200 mg of sodium carboxymethyl
cellulose, 5 mg of sodium benzoate, 1.0 g of sorbitol
solution, U.S.P., and 0.025 mg of vanillin.
In~ectable
A parenteral composition suitable for administration by
injection can be prepared by stirring 1.5~ by weight of
active ingredient in 10~ by volume propylene glycol and
water. The solution is sterilized by commonly used
techniques.
C9mbination of components (a1 and lb)
Each therapeutic agent component of this invention can
independently be in any dosage form, such as those described
above, and can also be administered in various ways, as
described above. In the following description component (b)
is to be understood to represent one or more agents as
described previously. Thus, if components (a) and (b) are to
be treated the same or independently, each agent of component
(b) may also be treated the same or independently.
Components (a) and (b) of the present invention may be
formulated together, in a single dosage unit (that is,
combined together in one capsule, tablet, powder, or liquid,
etc.) as a combination product. Vdhen component (a) and (b)
are not formulated together in a single dosage unit, the
component (a) may be administered at the same time as
component (b) or in any order; for example component (a) of
this invention may be administered first, followed by
administration of component (b), or they may be administered
in the revserse order. If component (b) contains more that
one agent, e.g., one RT inhibitor and one protease inhibitor,
122
r i
CA 02284996 1999-09-27
WO 98/45276 PCT/US98/06733
these agents may be administered together or in any order.
V~Then not administered at the same time, preferably the
administration of component (a) and (b) occurs less than
about one hour apart. Preferably, the route of
administration of component (a) and (b) is oral. The terms
oral agent, oral inhibitor, oral compound, or the like, as
used herein, denote compounds which may be orally
administered. Although it is preferable that component (a)
and component (b) both be administered by the same route
(that is, for example, both orally) or dosage form, if
desired, they may each be administered by different routes
(that is, for example, one component of the combination
product may be administered orally, and another component may
be administered intravenously) or dosage forms.
As is appreciated by a medical practitioner skilled in
the art, the dosage of the combination therapy of the
invention may vary depending upon various factors such as the
pharmacodynamic characteristics of the particular agent and
its mode and route of administration, the age, health and
weight of the recipient, the nature and extent of the
symptoms, the kind of concurrent treatment, the frequency of
treatment, and the effect desired, as described above.
The proper dosage of components (a) and (b) of the
present invention will be readily ascertainable by a medical
practitioner skilled in the art, based upon the present
disclosure. By way of general guidance, typically a daily
dosage may be about 100 milligrams to about 1.5 grams of each
component. If component (b) represents more than one
compound, then typically a daily dosage may be about 100
milligrams to about 1.5 grams of each agent of component (b).
By way of general guidance, when the compounds of component
(a) and component (b) are administered in combination, the
dosage amount of each component may be reduced by about 70-
80~ relative to the usual dosage of the component when it is
administered alone as a single agent for the treatment of HIV
infection, in view of the synergistic effect of the
combination.

The combination products of this invention may be
formulated such that, although the active ingredients are
combined in a single dosage unit, the physical contact
between the active ingredients is minimized. In order to
minimize contact, for example, where the product is orally
administered, one active ingredient may be enteric coated.
By enteric coating one of the active ingredients, it is
possible not only to minimize the contact between the
combined active ingredients, but also, it is possible to
control the release of one of these components in the
gastrointestinal tract such that one of these components is
not released in the stomach but rather is released in the
intestines. Another embodiment of this invention where oral
administration is desired provides for a combination product
wherein one of the active ingredients is coated with a
sustained-release material which effects a sustained-release
throughout the gastrointestinal tract and also serves to
minimize physical contact between the combined active
ingredients. Furthermore, the sustained-released component
can be additionally enteric coated such that the release of
this component occurs only in the intestine. Still another
approach would involve the formulation of a combination
product in which the one component is coated with a sustained
and/or enteric release polymer, and the other component is
also coated with a polymer such as a lowviscosity grade of
hydroxypropyl methylcellulose or other appropriate materials
as known in the art, in order to further separate the active
components. The polymer coating serves to form an additional
barrier to interaction with the other component. In each
forniulation wherein contact is prevented between components
(a) and (b) via a coating or some other material, contact may
also be prevented between the individual agents of component
(b) .
Dosage forms of the combination products of the present
invention wherein one active ingredient is enteric coated can
be in the form of tablets such that the enteric coated
component and the other active ingredient are blended
together and then compressed into a tablet or such that the
124
r
CA 02284996 1999-09-27
WO 98145276 PCTIUS98106733
enteric coated component is compressed into one tablet layer
and the other active ingredient is compressed into an
additional layer. Optionally, in order to further separate
the two layers, one or more placebo layers may be present
such that the placebo layer is between the layers of active
ingredients. In addition, dosage forms of the present
invention can be in the form of capsules wherein one active
ingredient is compressed into a tablet or in the form of a
plurality of microtablets, particles, granules or non-perils,
which are then enteric coated. These enteric coated
microtablets, particles, granules or non-perils are then
placed into a capsule or compressed into a capsule along with
a granulation of the other active ingredient.
These as well as other ways of minimizing contact
between the components of combination products of the present
invention, whether administered in a single dosage form or
administered in separate forms but at the same time or
concurrently by the same manner, will be readily apparent to
those skilled in the art, based on the present disclosure.
Pharmaceutical kits useful for the treatment of HIV
infection, which comprise a therapeutically effective amount
of a pharmaceutical composition comprising a compound of
component (a) and one or more compounds of component (b), in
one or more sterile containers, are also within the ambit of
the present invention. Sterilization of the container may be
carried out using conventional sterilization methodology well
known to those skilled in the art. Component (a) and
component (b) may be in the same sterile container or in
separate sterile containers. The sterile containers of
materials may comprise separate containers, or one or more
multi-part containers, as desired. Component (a) and
component (b), may be separate, or physically combined into a
single dosage form or unit as described above. Such kits may
further include, if desired, one or more of various
conventional pharmaceutical kit components, such as for
example, one or more pharmaceutically acceptable carriers,
additional vials for mixing the components, etc., as will be
readily apparent to those skilled in the art. Instructions,
