Synthesis and in vitro activity of various derivatives of a novel thromboxane receptor antagonist, (.+-.)-(5Z)-7-[3-endo[(phenylsulfonyl)amino]bicyclo[2.2.1]hept-2-exo-yl]heptenoic acid
Several sulfonyl derivatives (13a-t) of (+/-)-(5Z)-7-(3-endo-aminobicyclo[2.2.1]hept-2-exo-yl)heptenoic acid (VI) were synthesized via its methyl ester 10. Sulfonylation of 10 with 11a-t followed by saponification yielded 13a-t. Inhibitory concentrations (IC50) of the corresponding sodium salts 14a-t for plateletaggregation were measured with rat washed platelets (WP) and rabbit platelet-rich plasma
