Discovery of IRL 3461: a novel and potent endothelin antagonist with balanced ETA/ETB affinity
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 ET, selective antagonist. IRL 3461 was found to be stable on incubation with human, rat, mouse, and guinea pig plasmas. (C) 1998 Elsevier Science Ltd. All rights reserved.
