通过计算设计了一系列含有稠环或联芳基部分的 β 分泌酶 1 和 2 (BACE1, 2) 抑制剂的过渡态类似物,以探测 S2 口袋,进行合成并测试 BACE1 和 BACE2 抑制活性。研究表明,与联芳基类似物不同,稠合环部分成功地容纳在 BACE1 结合位点中,从而使配体具有优异的抑制活性。在用瑞典人 APP 稳定转染的 N2a 细胞中,配体 5b 降低了 65% 的 Aβ40 产量。
A series of transition-state analogues of beta-secretases 1 and 2 (BACE1, 2) inhibitors containing fused-ring or biaryl moieties were designed computationally to probe the S2 pocket, synthesized, and tested for BACE1 and BACE2 inhibitory activity. It has been shown that unlike the biaryl analogs, the fused-ring moiety is successfully accommodated in the BACE1 binding site resulting in the ligands with excellent inhibitory activity. Ligand 5b reduced 65% of Aβ40 production in N2a cells stably transfected with Swedish human APP.
