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.

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 ', ' ' ' . ' ' ` : ~ ~

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 . .

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 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 ', ' ' ' . ' ' ` : ~ ~

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 . .
