and improving biopharmaceutical properties. From this effort, (R)-14c was identified as a potent nonsteroidal MR antagonist (IC50 = 4.5 nM) with higher than 500-fold selectivity versus PR and other related nuclear hormone receptors, with improved solubility as compared to 2 and pharmacokinetic properties suitable for oral administration. (R)-14c was evaluated in vivo using the increase of urinary Na+/K+
报告了一系列新的非甾体类盐皮质激素受体(MR)拮抗剂,这些拮抗剂被确定为我们对临床候选药物PF-03882845(2)进行随访的策略的一部分。优化摆脱了先前描述的吡唑啉3a,并着重于提高对MR与孕酮受体(PR)的选择性,以此作为避免潜在的性激素相关副作用和改善生物药物特性的方法。从这一努力中,(R)-14c被确定为一种有效的非甾体MR拮抗剂(IC 50 = 4.5 nM),相对于PR和其他相关核激素受体的选择性高出500倍,与2相比,其溶解度有所提高和适合口服的药代动力学性质。使用大鼠中尿Na + / K +比的增加作为MR拮抗作用的机制生物标志物,对(R)-14c进行了体内评估。通过口服给药(R)-14c的治疗导致尿中Na + / K +比率显着增加,并证明该新型化合物可作为MR拮抗剂。
