摘要

IRL 3461, N-butanesulfonyl-[N-(3, 5-dimethylbenzoyl)-N-methyl-3-[4-(5-isoxazolyl)-phenyl]- alanyl]-(L)-valineamide, a potent and bifunctional (ETA+ ETB)[Ki (ETA)= 1.8 nM, Ki (ETB)= 1.2 nM] antagonist was discovered by structural modification of IRL 2500, an ETB selective antagonist. IRL 3461 was found to be stable on incubation with human, rat, mous, and guinea pig plasmas.
