A series of 1-methyl-3,5-diphenyl-4,5-dihydro-1H-pyrazoles (3a–k and 4a–u) were designed, synthesized, and evaluated for their inhibitory efficacy towards the two hMAO isoforms. Most of the derivatives were found to be potent and selective hMAO-B inhibitors. In particular, derivative 3g showed greater hMAO-B affinity than selective inhibitor selegiline coupled with high selectivity index (SI = 145)
设计,合成了一系列1-甲基-3,5-二苯基-4,5-二氢-1 H-吡唑类化合物(3a - k和4a - u),并评估了它们对两种hMAO同工型的抑制作用。发现大多数衍生物是有效的和选择性的hMAO-B抑制剂。尤其是,衍生物3g与选择性抑制剂司来吉兰相比具有更高的hMAO-B亲和力,并具有高选择性指数(SI = 145)。最具选择性的hMAO-B抑制剂是3-甲基类似物3f,SI高于909。
