synthesized and evaluated as inhibitors of phenylethanolamine N-methyltransferase (PNMT; EC 2.1.1.28) and as inhibitors of the binding of clonidine at the alpha(2)-adrenoceptor. 4-Fluoro-THBAs 13-15 displayed selectivity ratios (alpha(2) K(i)/PNMT K(i)) greater than 75 and 4-fluoro-8-nitro-THBA (13) was found to be one of the most selective inhibitors of PNMT known, with a selectivity ratio of greater
合成了少量的4-氟-8-取代的2,3,4,5-四氢-1H-2-苯并氮平(4-氟-THBAs; 12-15)并作为苯基乙醇胺N-甲基转移酶的抑制剂进行了评估( PNMT; EC 2.1.1.28)和可乐定在α(2)-肾上腺素受体上的结合抑制剂。4-氟THBAs 13-15的选择性比(alpha(2)K(i)/ PNMT K(i))大于75,而4-氟-8-硝基THBA(13)是其中之一已知大多数PNMT选择性抑制剂的选择性比都大于900。这些化合物也具有亲脂性,根据该实验室先前的结果,该化合物应能够穿透血脑屏障。这些4-氟代THBAs在开发新的,选择性更高的PNMT CNS活性抑制剂中代表了重要的线索。
