Cyclopentane Derivatives, Process for their Production
and their Pharmaceutical Use
Description:
The invention relates to cyclopentane derivatives, process
for their production as well as their use as auxiliary agents for
pharmacological studies and as pharmaceutical agents.
Cyclopentane derivatives have been dealt with intensively in
recent years, since prostaglandins derived from the cyclopentane
system, such as, e.g., PGA2, PGBz, PGE2, 6-oxo-PGE1, PGD2, PGF2a,
PGJz and their analogs, have the most varied biological actions,
e.g., on the cardiovascular system, the central nervous system or
immune system.
It has been found, surprisingly, that by the introduction of
a fluorine atom or a hydroxy group in 9 position (prostaglandin
numbering system) of the prostaglandin skeleton in combination
with the most varied structural features in the lower chain as
well as in 11-position, chemically and metabolically stable
prostaglandin analogs are obtained which are able to antagonize
the pharmacological properties of unstable thromboxane A2 (TXA2)
or PGH2 as well as its stable analogs, such as, e.g., U46619 or
U44069 on the receptor.
The compounds of this invention therefore constitute
valuable auxiliary agents for selective treatment of diseases,
which are attributable to an excess of TXA2 or PGH2.

The release of functionally modified hydroxy groups R2, R3,
R4 and W takes place according to the methods known to one
skilled in the ar~. For example, the cleavage of ether
protecting groups is performed in an aqueous solution of an
organic acid, such as, e.g., acetic acid, propionic acid, citric
acid, i.a, or in an aqueous solution of an inorganic acid, such
as, e.g., hydrochloric acid, or in the case of tetrahydropyranyl
ethers with use of pyridinium-p-toluenesulfonate, preferably in
alcohols as solvent or with use of anhydrous magnesium bromide,
preferably in diethyl ether as solvent.

~88~
To improve the solubility, a water-miscible inert solvent is
suitably added with use of aqueous-acid reaction conditions.
Proven as suitable, there are, e.g., alcohols, such as methanol
and ethanol, ethers, such as dimethoxyethane, dioxane and
tetrahydrofuran, and tetrahydrofuran is preferably used.
The cleavage of silylether protecting groups takes place,
for example, with tetrabutylammonium fluoride according to the
methods known to one skilled in the art. As solvent, for
example, tetrahydrofuran, diethyl ether, dioxane, methylene
chloride, etc., are suitable. The cleavage is performed
preferably at temperatures between 20C and 80C.
The saponification of the acyl groups and ester in COORs of
the cyclopentane derivatives is performed according to the
methods known to one skilled in the art, such as, for example,
with basic catalysts, such as, e.g., with alkali or alkaline-
earth carbonates or hydroxides in an alcohol or the aqueous
solution of an alcohol. As alcohols, aliphatic alcohols, such
as, e~g., methanol, e~hanol, butanol, etc., but preferably
methanol, are suitable. As alkali carbonates and hydroxides,
lithium, sodium and potassium salts can be mentioned. The
lithium and potassium salts are preferred. As alkaline-earth
carbonates and hydroxides, for example, calcium carbonate,
calcium hydroxide and barium carbonate are suitable. The
reaction generally takes place at -10C to ~70C, but preferably
at +25C.
The introduction of ester group Co2R5 for R1 or C02R6 ~or Y,
in which R5 or R6 represents an alkyl group with 1-10 C atoms,
`
.:
', ' '~ :
.
2~8~
takes place according to the methods Xnown to one skilled in the
art. The carboxy compounds (Rs = H or R6 = H) are reacted, for
example, with diazohydrocarbons in a way known in the art. The
esterification with diazohydrocarbons takes place, e.g., in that
a solution of the diazohydrocarbon in an inert solvent,
preferably in diethyl ether, is mixed with the carboxy compound,
dissolved in the same or in another likewise inert solvent, such
as, e.g., methylane chloride. After completion of the reaction
within 1 to 60 minutes, the solvent is removed and the ester is
purified in the usual way. Diazoalkanes are either known or can
be produced according to known methods [Org. Reactions, Vol. 8,
pages 389-394 (1954)].
The introduction of ester group CO2Rs for R1 or CO2R6 for Y,
in which R5 or R6 represents a substituted or unsu~stituted aryl
group, takes place according to the methods known to one skilled
in the art. For example, the 1-carboxy compounds are reacted
with the corresponding arylhydroxy compounds with
dicyclohexylcarbodiimide in the presence of a suitable base, such
as, e.g., pyridine, DMAP, triethylamine, in an inert solvent,
su~h as, e.g., methylene chloride, ethylene chloride, chloroform,
ethyl acetate, tetrahydrofuran, but preferably with chloroform.
The reaction is performed at temperatures between -30C and
~50C, preferably at +10C.
The cyclopentane derivatives of formula I with Rs or R6
meaning a hydrogan atom can be convarted to salts with suitable
amounts of the corresponding inorganic bases with neutralization.
For example, by dissolving the corresponding acids in water,
. ...
~'
,: ~
2~8~ 1
which contains stoichiometric amounts of the base, the solid
inorganic salt is obtained after evaporation of the water or
after addition of a water-miscible solvent, e.g., alcohol or
acetone.
The production of the amine salts takes place in the usual
way. For this purpose, the acid is dissolved in a suitable
solvent, such as, e.g., ethanol, acetone, diethyl ether or
benzene and 1 to 5 equivalents of the respective amine is added
to this solution. In this case, the salt usually accumulates in
solid form or is isolated in the usual way after evaporation of
the solvent.
The functional modification of the free hydroxy groups takes
place according to the methods known to one skilled in the art.
For the introduction of the ether protecting groups, the reaction
is performed, for example, with dihydropyran or methyl vinyl
ether in methylene chloride or chloroform with use of catalytic
amounts of an acid condensing agent, such as, e.g., p-
toluenesulfonic acid. The respecti~e enol ether is added in
excess, preferably in 1.2 to 10 times the amount of the
theoretical requirement. The reaction normally takes place at -
10C to +30C and is completed after 2 to 45 minutes.
For the introduction of silylether protecting groups, the
reaction is performed, for example, with t-butyl-
diphenylchlorosilane or t-butyl-dimethylchlorosilane in
dimethylformamide with use of a base, such as, e.g., imidazole.
The respective silyl chloride is added in excess, preferably in
1.05 to 4 times the amount of the theoretical requirement. The
-
reaction normally takes place at 0C to 30C and is completed
after 1 to 24 hours.
The introduction of the acyl protecting groups takes place
by a compound of formula I being reacted in a way known in the
art with a carboxylic acid derivative, such as, e.g., acid
chloride, acid anhydride, etc.
Cyclodextrin clathrates are obtained analogously to the
instructions in WO 87/05294.
Liposomes are produced according to t~e production process
described in "Pharmazie in unserer Zeit [Pharmaceutics in Our
Time] 11, 98 (1982)."
All stereoisomeric forms are also part of the object of the
invention.

Biolo~ical Ac_ion and Ran~e of APplication of the New TXA2
Antagonists:
The compounds of this invention are suitable for treatment
of diseases of the cardiovascular system, the stomach, the
pancreas, the liver and the kidneys. They work in an
antihypertensive and bronchodilatory manner. They are
excellently suited for inhibition of the activation of platelets.
Consequently, the new TXA2 antagonists of formula I represent
valuable pharmaceutical active ingredients. Moreover, the
compounds are distinguished by higher selectivity, a
substantially longer effectiveness and a greater stability than
similar TXA2 antagonists.
The new TXA2 antagonists have the properties typical for
this family of compounds, such as, e.g., reduction of the
peripheral arterial, the coronary and the pulmonary vascular ~
resistance, reduction of the pulmonary blood pressure, reduction
of the systemic blood pressure without at the same time reducing
the cardiac output and coronary blood circulation, promotion of
the kidney blood circulation and the blood circulation of other
peripheral organs, increase of the cerebral blood circulation,
inhibition of the platelet activation and dissolution of blood
clots, inhibiti~n of bronchoconstriction, inhibition of gastric
acid secretion, cytoprotection of the heart, the stomach and
intestinal mucous membrane, the liver, cytoprotection in the
pancreas and in the kidneys as well as antiallergic properties.
Therefore, the new TXA2 antagonists are suitable on principle for
treatment of stroke, prophylaxis and treatment of coronary heart

diseases, for example, coronary thrombosis, for treatment of
myocardial infarction, peripheral arteriopathies, for prophylaxis
and treatment of other thromboembolic diseases and in
arteriosclerosis, in ischemic attacks of the central nervous
system and other disturbances of the blood circulation of the
brain, such as, e.g., migraine, for treatment of hypertonia and
for treatment of diseases which accompany an increase of the
pulmonary vascular resistance, such as, e.g., the pulmonary
hypertonia and for treatment of shock, asthma and allergic
rhinitis. They can further be used to inhibit labor pains and
for treatment of toxicoses in pregnancies.
Further, the new TXA2 antagonists can be used to improve the
organ function after transplantation, for example, in kidney
transplantation, to prevent rejection reactions, instead of
heparin or as adjuvant in the case of dialysis or hemofiltration
and in the case of storing dried blood plasma, for example, dried
blood platelets.
The new TXA2 antagonists have an antimetastatic action and
antiproliferative properties. They are suitable on principle for
treatment o~ neoplasias. The new TXA2 antagonists can be used in
combination with, for example, carbacyclins, prostacyclin and its
analogs, 7-oxoprostacyclins, prostaglandins and their derivatives
and 6-oxo-PGE1- and 6-oxo-9-fluoroprostaglandin derivatives, with
TXA2-synthetase inhibitors, with phosphodiesterase inhibitors,
with antagonists and receptor antagonists of various platelet
stimulators (e.g., ADP, thrombin, collagen, PAF, adrenaline,
serotonin, fibrinogen), with calcium antagonists, with
. .
:

fibrinolytic agents and thrombolytic agents, e.g., t-PA,
streptokinase, with heparin and other anticoagulants, with
cyclooxygenase inhibitors, e.g., acetylsalicylic acid, with
inhibitors of lipoxygenases as well as antagonists of
lipoxygenase products, with vasodilators, such as, e.g., nitro
compounds, with antihypertensive agents, such as, e.g., ~-
blockers or with diuretics.
The dose of the compounds is 0.1-1000 mg/day, preferably
0.1-500 mg/day, also in several partial doses, if they are
administered to human patients. The unit dose for the
pharmaceutically acceptable vehicle is 0.1-100 mg. For
parenteral administration, sterile, injectable aqueous or oily
solutions are used. For oral administration, for example,
tablets, coated t~blets, or capsules are suitable.
Thus, the invention also relates to pharmaceutical agents
based on the compounds of general formula I and usual auxiliary
agents and vehicles.
The active ingredients according to the invention are to be
used in connection with the auxiliary agents known and usual in
galenicals, e.g., for the production of antihypertensive agents.
The unit dose range for the ampule is 0.1-100 mg, for the
tablet 0.1-100 mg.
