摘要:
What is disclosed are prostacyclin analogs of the general formula I ##STR1## which have a more specific action and/or a longer action than the naturally occurring prostacyclin PGI.sub.2, as well as intermediate products for their preparation and a process for their preparation. The compounds of formula I are distinguished by inhibitory action on thrombocyte aggregation and by relaxation of the vascular walls, in particular of the coronary arteries. They can thus be used as medicaments.
摘要:
What is disclosed are prostaglandin-analogous cyclopentane derivatives of the formula I ##STR1## wherein R.sup.1 is hydrogen or a linear or branched, saturated or unsaturated aliphatic or cycloaliphatic radical having from 1 to 8 carbon atoms, or an araliphatic radical having from 7 to 9 carbon atoms, or a physiologically tolerable metal, NH.sub.4 or substituted ammonium ion derived from a primary, secondary or tertiary amine;R.sup.2 is a linear or branched, saturated or unsaturated aliphatic hydrocarbon radical having from 1 to 8 carbon atoms;R.sup.3 is hydrogen or a R.sup.4 CO group wherein R.sup.4 is a hydrogen atom or a linear or branched alkyl group having up to 10 carbon atoms;A is a saturated, linear or branched alkylene group having from 2 to 5 carbon atoms, and a process for the manufacture thereof.
摘要:
The present invention relates to pyrrolidones which are analogues of prostaglandins and to a process for their manufacture. The compounds of the invention have prostaglandin-like pharmacological properties and can therefore be used as pharmaceutical compositions.
摘要:
The present invention relates to cyclopentane derivatives similar to prostaglandins. Due to their antiprostaglandin effect they have valuable properties as medicaments.
摘要:
What is disclosed are compounds of the formula ##STR1## which are structurally related to natural prostaglandins and a process for their manufacture. The compounds have valuable pharamacological properties and, therefore, they can be used as medicaments.
摘要:
A description is given of compounds I ##STR1## with R(1) equal to H, alkyl, alkoxy, Hal, NO.sub.2, OH, acetamido or amino; R(2) equal to H, alk(en)yl or phenylalkyl; R(3) equal to H, (cyclo)alk(en)yl(alkyl), phenyl or phenylalkyl; R(4) equal to H, alkyl, alkoxy, Hal CF.sub.3, NO.sub.2, OH, acetamido or amino; A equal to --C.tbd.C-- or --CH.dbd.CH--; R(5) equal to various amines; m and n equal to 1-3; and their salts. Preparation processes are also described. Compounds I are excellent calcium agonists or calcium antagonists. They also act to regulate the blood glucose.
摘要:
The invention relates to new prostaglandin derivatives of the 6-keto-PGE.sub.1 series, to processes and intermediates for their manufacture and to their use as medicaments.
摘要:
The present invention relates to new cyclopentane derivatives having the formula ##STR1## and to a process for their manufacture. The compounds can be used as medicaments due to their antiprostaglandin effect.
摘要:
The present invention relates to novel not naturally occurring analogues of prostanoic acids of the formula ##STR1## as well as a process for their preparation. The compounds of the invention have valuable pharmacological properties similar to those of the natural prostaglandins and therefore can be used as medicaments.
