摘要:
Compounds are described of the formulae (1a) and (1b) in which: -COR' is an ester group, n is 1 or 2, W is C 1-7 alkylene, X is cis or trans -CH= CH or -CH 2 CH 2 -, Y is a saturated heterocyclic amino group, R 2 is substituted or unsubstituted phenylalkyl, thienylal- kyl or naphthylalkyl or cinnamyl, and R' is -H or C 1-5 alkanoyl, including their salts. These compounds inhibit blood platelet aggregation and bronchoconstriction and may be formulated for use as antithrombotic or antiasthmatic agents.
in which -COR 1 is a complex ester or thioester group, W is alkylene, X is cis or trans -CH=CH or -CH 2 CH 2 -, n is 1 or 2, Y is a saturated heterocyclic amino group having 5 - 8 ring members, and R 2 is unsubstituted or substituted phenylalkyl, thienylalkyl, naphthylalkyl or cinnamyl, and their salts and solvates.
These compounds inhibit blood platelet aggregation and bronchoconstriction and may be formulated for use as antithrombotic and antiasthmatic agents.
