structure of human nonpancreatic secretory phospholipase A2 (hnps PLA2). Their inhibition activities against hnps PLA2 were improved compared to that of the monofunctional protocompound. These bivalent ligands not only inhibited hnps PLA2 but also drove the dimerization of hnps PLA2. Their dimerization ability correlated with the linker length and position. Further study on the potent compound 5 (1
根据酶的结构设计合成了一系列新型的双吲哚化合物1,ω-双(((3-乙酰氨基-5-甲氧基-2-甲基吲哚)-2-亚甲基)苯氧基)烷烃。人非胰腺分泌性磷脂酶A2(hnps PLA2)的表达。与单功能原化合物相比,它们对hnps PLA2的抑制活性有所提高。这些二价配体不仅抑制了hnps PLA2,而且还推动了hnps PLA2的二聚化。它们的二聚能力与接头长度和位置相关。对有效化合物5(1,5-双(((3-乙酰氨基-5-甲氧基-2-甲基吲哚)-2-亚甲基)苯氧基)戊烷,IC50 = 24 nM)的进一步研究表明,两者之间存在协同结合相互作用酶分子也有助于三元复合物的稳定性。
