Highly potent HIV-1 protease (HIVPR) inhibitors have been designed and synthesized by introducing bidentate hydrogen-bonding oxime and pyrazole groups at the meta-position of the phenyl ring on the P2/P2' substituents of cyclic ureas. Nonsymmetrical cyclic ureas incorporating 3(1H)-pyrazolylbenzyl as P2 and hydrophilic functionalities as P2' show potent protease inhibition and antiviral activities
通过在环状脲的P2 / P2'取代基上苯环的间位引入二齿氢键合肟和吡唑基,可以设计和合成高效HIV-1蛋白酶(HIVPR)抑制剂。包含3(1H)-吡唑基苄基作为P2和亲水性官能团作为P2'的非对称环状脲显示出强大的蛋白酶抑制作用和针对HIV的抗病毒活性,并具有良好的口服生物利用度。HIVPR.10A复合物的X射线结构证实,两个10A的吡唑环与HIVPR的Asp30 / 30'的侧链氧(C = O)和主链氮(NH)形成双齿氢键。
