in vivo over both the nonselective inhibitor tolcapone 1 and the peripherally selective but short-acting entacapone 2. In this model, 35 retained 75% inhibition of peripheral COMT at 6 h after oral administration, yet significantly, only a minor reduction of central (cerebral) COMT activity was observed. Molecular modeling techniques were applied to review the analysis of the ternary enzyme-inhibitor
已经合成了一系列新型的,有效的,周边选择性的和长效的儿茶酚-O-甲基转移酶(COMT)抑制剂。发现在硝基邻苯二酚药效团的侧链上含有杂原子的取代基的引入和性质对小鼠的外周选择性和COMT抑制的持续时间都具有深远的影响。这种方法导致发现了1-(3,4-二羟基-5-硝基苯基)-3- [4- [3-(三氟甲基)苯基] -1-哌嗪基] -1-丙酮丙酮盐酸盐35(BIA 3-335 ),该药物在体内具有比非选择性抑制剂tolcapone 1和外周选择性但短效的entacapone 2优异的抑制特性。在该模型中,口服给药后6 h,35保留了对外周COMT的75%抑制,但是很重要的是 仅观察到中枢(大脑)COMT活性略有降低。应用分子建模技术来审查先前由X射线晶体学确定的三元酶抑制剂复合物的分析,并提供对该新系列中的结构活性关系的更深入的了解。此外,为了阐明与35的血脑通透性差有关的特定结构因素,采用了一
