A series of new 2-methoxy-4-(5-phenyl-4,5-dihydro-1H-pyrazol-3-yl)phenolderivatives, 4–13, were synthesized and tested for their human MAO inhibitory activity. All the compounds were found to be selective and reversible toward hMAO-A except 4, a selective inhibitor of hMAO-B and 12, a nonselective inhibitor. Compound 7 was found to be a potent inhibitor of hMAO-A with Ki = 0.06 ± 0.003 μM and was having
一系列新的2-甲氧基-4-(5-苯基-4,5-二氢-1- ħ吡唑-3-基)phenolderivatives,4 - 13,合成以及它们的人MAO抑制活性进行测试。发现除了hMAO-B的选择性抑制剂4和非选择性抑制剂12以外,所有化合物均对hMAO-A具有选择性和可逆性。发现化合物7是hMAO-A的有效抑制剂,K i = 0.06± 0.003μM ,选择性指数为(SI = 1.02×10 –5)。已发现它比标准药物莫氯贝胺(hMAO-A,K i =0.11±0.01μM),选择性指数SI = 0.049。进行分子对接模拟以了解负责选择性和效能的关键相互作用。
