The synthesis, evaluation, and structure-activity relationships of a class of acyl guanidines which inhibit the BACE-1 enzyme are presented. The prolinyl acyl guanidine chemotype (7c), unlike compounds of the parent isothiazole chemotype (1), yielded compounds with good agreement between their enzymatic and cellular potency as well as a reduced susceptibility to P-gp efflux. Further improvements in
介绍了抑制BACE-1酶的一类酰基胍的合成,评估和构效关系。与母体异噻唑化学类型(1)的化合物不同,脯氨酰基酰基胍化学类型(7c)产生的化合物在其酶促和细胞效能之间具有良好的一致性,并且对P-gp外排的敏感性降低。通过大环化策略实现了效力和P-gp比的进一步提高。给出了野生型小鼠体内的概况和大环类似物21c的P-gp效应。
