Alkylidene-Tetrahydronaphthalene Derivatives, Process for Their Production and
Their Use as 4ntiInflammatory Agents
The'invention relates to alkylidene-tetrahydronaphthalene derivatives, process
for their production and their use as anti-inflammatory agents.
Open-chain, non-steroidal anti-inflammatory agents are known from the prior
art
WO 02/10143 and WO 03/082827. In the experiment, these compounds show
,_.. .l
dissociations of action between anti-inflammatory and undesirable metabolic
actions and
are superior fo the previously described nonsteroidal glucocorticoids or
exhibit at least
just as good an action.
The selectivity of the compounds of the prior art compared to the other
steroid
receptors still requires improvement, however.
It was therefore the object of this invention to make available compounds
whose
selectivity is improved but is at least comparable relative to the other
steroid receptors.
f.... ,~. This object is achieved by the compounds of this invention,
explained in the
~ . ~ claims.

The binding of substances to the glucocordcoid receptor (OR) and other steroid-
hormone receptors (mineral corticoid receptor (MR), progesterone receptor (PR)
and
androgen receptor (AR)) is examined with the aid of recombinantly produced
receptors.
Cytosol preparations of Sfzl cells, which had been infected with recombinant
baculoviruses that code for the GR, are used for the binding studies. In
comparison to
CA 02577861 2007-02-21
24
the reference substance [3H]-dexamethasone, the substances show a high
affinity to the
GR IC50(GR) = 20 nM and IC5a(PR) > I lvl were measured for the compound from
Example 1, and ICso(GR) = 30 nM and= IC5o(PR) > I M were measured for the
compound from Example 2.
The GR-mediated inhibition of the transcription of cytokines, adhesion
molecules, enzymes and other pro-inflammatory factors is considered to be an
essential,
molecular mechanism for the anti-inflammatory action of glucocorticoids. This
inhibition is produced by an interaction of the GR with other transcription
factors, e.g.,
AP-1 and NF-kappa-B (for a survey, see Cato, A. C. B., and Wade, E., BioEssays
18,
37I-378, 1996).
The compounds of general formula I according to the invention inhibit the
secretion of cytokine IL-8 into the human monocyte cell line THP-1 that is
triggered by
lipopolysaccharide (LPS). The concentration of the cytokines was determined in
the
supernatant by means of commercially available ELISA kits. The compound of
Example I showed an inhibition ICso(IL8) = 6.4 nM at a 90% efficiency relative
to [3H1-
dexamethasone as a standard.
The anti-inflammatory action of the compounds of general fonnula I was tested
in the animal experiment by tests in the croton oil-induced inflammation in
rats and mice
(J. Exp. Med. (1995),182, 99-108). To this end, croton oil in ethanolic
solution was
applied topically to the animals' ears. The test substances were also applied
topically or
systemically at the same time or two hours before the croton oil. After 16-24
hours, the
ear weight was measured as a yardstick for inflammatory edema, the peroxidase
activity
as a yardstick for the invasions of granulocytes, and the elastase activity as
a yardstick
for the invasion of neutrophilic granulocytes. In this test, the compounds of
general
CA 02577861 2007-02-21
- 25
formula I inhibit the three above-mentioned inflammation parameters both after
topical
administration and after systemic administration.
One of the most frequent undesirable actions of a glucocorticoid therapy is
the
so-called "steroid diabetes" [cf., Hatz, H. J., Glucocorticoide:
Immunologische
Grundlagen, Pharmakologie und Therapierichtlinien, [Glucocorticoids:
Immunological
Bases, Phannacology and Therapy Guidelines], Wissenschaftliche
Verlagsgesellschaft
mbH, Stuttgart, 1998]. The reason for this is the stimulation of
gluconeogenesis in the
liver by induction of the enzymes responsible in this respect and by free
amino acids,
which are produced from the degradation of proteins (catabolic action of
glucocorticoids). A key enzyme of the catabolic metabolism in the liver is
tyrosinamino
transferase (TAT). The activity of this enzyme can be determined from liver
homogenates by photometry and represents a good measurement of the undesirable
metabolic actions of glucocorticoids. To measure the TAT induction, the
animals are
sacrificed 8 hours after the test substances are administered, the livers are
removed, and
the TAT activity is measured in the homogenate. In this test, at doses in
which they
have an anti-inflammatory action, the compounds of general formula I induce
little or no
tyrosinamino transferase.
Because of their anti-inflammatory action, and, in addition, anti-allergic,
immunosuppressive and antiproliferative action, the compounds of general
formula I
according to the invention can be used as medications for treatment or
prophylaxis of the
following pathologic conditions in mammals and humans: In this case, the term

acid is
added. It is stirred for 10 minutes, extracted with ethyl acetate, washed with
saturated
sodium bicarbonate and sodium chloride solution, dried on sodium sulfate, and
the
solvent is removed in a vacuum. The separation on silica gel (hexane/ethyl
acetate 5-
50%) by column chromatography yields 6.4 g of 3-(2-fluorophenoxy)-
propionitrile. 6.4
g (38.8 mmol) of 3-(2-fluorophenoxy)-propionitrile is refluxed in 38.6 ml of
concentrated hydrochloric acid over 2 hours. At room temperature, it is
diluted with ice
water and stirred for 10 minutes. It is extracted with ethyl acetate, washed
with
saturated ammonium chloride solution and dried on sodium sulfate. After the
solvent is
removed in a vacuum, 6.5 g of 3-(2-fluorophenoxy)-propionic acid is obtained.
6.5 g
(35.6 nunol) of 3-(2-fluorophenoxy)-propionic acid is added to 39 g of
polyphosphoric
acid and stirrrnd for four hours at 70 C. After cooling overnight, it is
poured into ice
water. It is extracted with ethyl acetate, washed with saturated sodium
bicarbonate and
sodium chloride solution and dried on sodium sulfate. After the solvent is
removed in a
vacuum, 5.5 g of 8-fluorochroman-4-one is obtained as a crystalline solid.

mixture is
carefully added to a mixture of 4 M hydrochloric acid and ice. The phases are
separated,
extracted with diethyl ether, washed with water, dried on sodium sulfate, and
the solvent
is removed. The crude product is purified by column chromatography on silica
gel
(hexane/isopropyl ether 0-20%), and 0.81 g of 8-fluoro-4-methylene-chroman is
obtained.
0.98 ml (0.49 mmol) of a 0.5 M titanium tetraisopropylate solution in toluene
is
added to 281 mg (0.98 mmol) of 1,1'-bi-2-naphthol, and the red solution is
stirred for 2

and
1.21 ml (9.8 mmol) of ethyltrifluoropyruvate are added, and the mixture is
heated over 3
hours to 120 C. After cooling, it is immediately purified by column
chromatography on
S
silica gel (hexane%thyl acetate 0-20%), and 0.69 g of 3-(8-fluoro-2H-chromen-4-

ethyl
ester is cooled in 10 ml of diethyl ether to -5 C, and 78 mg (2.0 mmol) of
lithium
aluminum hydride is added in portions in solid form over 10 minutes. It is
stirred for 2
