摘要:
The design of a series of thromboxane receptor antagonists based on 3-(2-[{(4-chlorophenyl)sulfonyl}amino]ethyl)benzenepropanoic acid (1) is described. Addition of an arylmethyl group at the 5-position of 1 gave exceptionally potent agents in vitro and in vivo, with 13a (UK-147,535) giving complete blockade of the TxA(2) receptor for greater than 12 hours in dogs, following all oral dose of 0.1 mg/kg.
