To identify new highly selective EP4-agonists, further modification of the 16-phenyl moiety of 1 was continued. 16-(3-methoxymethyl)phenyl derivatives 13-(6q) and 16-(3-ethoxymethyl)phenyl derivatives 13-(7e) showed more selectivity and potent agonist activity than 1. 16-(3-methyl-4-hydroxy)phenyl derivative 18-(14e) demonstrated excellent subtype selectivity, while both its receptor affinity and agonist
为了鉴定新的高选择性EP4-激动剂,继续对1的16-苯基部分进行进一步修饰。16-(3-甲氧基甲基)苯基衍生物13-(6q)和16-(3-乙氧基甲基)苯基衍生物13-(7e)比1具有更高的选择性和强效激动剂活性。16-(3-甲基-4-羟基)苯基衍生物18-(14e)具有出色的亚型选择性,而其受体亲和力和激动剂活性均不如13-(6q)。还讨论了构效关系(SAR)。
