Three series of 3-(2-aminoheterocycle)-4-benzyloxyphenylbenzamide derivatives, 2-aminooxazoles, 2-aminothiazoles, and 2-amino-6H-1,3,4-thiadizines were designed, synthesized and evaluated as β-secretase (BACE-1) inhibitors. Preliminary structure-activity relationships revealed that the existence of a 2-amino-6H-1,3,4-thiadizine moiety and α-naphthyl group were favorable for BACE-1 inhibition. Among the synthesized compounds, 5e exhibited the most potent BACE-1 inhibitory activity, with an IC50 value of 9.9 μΜ and it exhibited high brain uptake potential in Madin-Darby anine kidney cell lines (MDCK) and a Madin-Darby canine kidney-multidrug resistance 1 (MDCK-MDR1) model.
设计、合成了三个系列的3-(2-氨基杂环)-4-苄氧基苯基苯甲酰胺衍生物、2-氨基恶唑、2-氨基噻唑和2-氨基-6H-1,3,4-噻嗪并作为β-分泌酶(BACE)进行评价。 -1)抑制剂。初步的构效关系表明,2-氨基-6H-1,3,4-噻嗪部分和α-萘基的存在有利于BACE-1的抑制。在合成的化合物中,5e表现出最有效的BACE-1抑制活性,IC50值为9.9 μM,并且在Madin-Darby犬肾细胞系(MDCK)和Madin-Darby犬肾多药中表现出高脑摄取潜力电阻 1 (MDCK-MDR1) 型号。
