Herein we report our efforts of developing reversible selective hMAO-B inhibitors based on isatin, a fragment in an X-ray crystal structure. Five different scaffolds were designed and many compounds were synthesized. Among them, compound A3 demonstrated very high potency and isoform selectivity against hMAO-B, 11 and 13 times more potent (IC50 = 3 nM) and 23.64 and 6.8 times more selective than the
在这里,我们报告了我们基于isatin(一种X射线晶体结构的片段)开发可逆的选择性hMAO-B抑制剂的努力。设计了五种不同的支架,并合成了许多化合物。其中,化合物A3对hMAO-B表现出非常高的效价和同工型选择性,效价(IC50 = 3 nM)高11和13倍,选择性强于标记药物司来吉兰和沙芬酰胺23.64和6.8倍。但是,将isatin的极性3-one基团(即在hMAO-B结合位点的疏水环境中)修饰成小的非极性疏水基团的努力并未带来改进的hMAO-B抑制剂,这可能会挑战我们的理解。系统中分子相互作用和分子识别的概念。
