M. Sato et al., SYNTHESIS AND EVALUATION OF NOVEL THIAZOLIDINE DERIVATIVES AS THROMBOXANE-A2 RECEPTOR ANTAGONISTS, Chemical and Pharmaceutical Bulletin, 42(3), 1994, pp. 521-529
A series of 3-benzoyl or 3-phenylsulfonyl-2-substituted thiazolidine d
erivatives were synthesized, and evaluated for their thromboxane A2 (T
XA2) receptor-antagonizing effect on pha,9alpha-(epoxymethano)prosta-5
(Z),13(E)-dienoic acid (U-46619)-induced aggregation of rabbit platele
t-rich plasma (PRP). A simple 2-arylthiazolidine derivative, -benzoyl-
2-(4-hydroxy-3-methoxyphenyl)thiazolidine (5a), showed mild TXA2 recep
tor antagonist activity. Modification of 5a led to henylsulfonyl)thiaz
olidin-2-ylmethyl]phenoxyacetic acid (29d), which showed 10 times more
potent TXA2 receptor antagonist activity than 5a.
