Fragment-based lead discovery has been successfully applied to the aspartyl protease enzyme beta-secretase (BACE-1). Fragment hits that contained an aminopyridine motif binding to the two catalytic aspartic acid residues in the active site of the enzyme were the chemical starting points. Structure-based design approaches have led to identification of low micromolar lead compounds that retain these
基于片段的先导发现已成功应用于天冬氨酰蛋白酶β-分泌酶(BACE-1)。化学起始点是含有结合到酶活性位点的两个催化天冬氨酸残基的氨基吡啶基序的片段命中。基于结构的设计方法已导致鉴定出保留这些相互作用并另外占据活性位点相邻疏水口袋的低微摩尔铅化合物。这些导线形成两个子系列,代表化合物4(IC50 = 25 microM)和6c(IC50 = 24 microM)。在后一个系列中,进一步的优化导致了8a(IC50 = 690 nM)。
