A series of potent nonpeptide inhibitors of the HIV protease have been identified. Using the structure of compound 3 bound to the HIV protease, bis tertiary amide inhibitor 9 was designed and prepared. Compound 9 was found to be about 17 times more potent than 3, and the structure of the protein-ligand complex of 9 revealed the inhibitor binds in an inverted binding mode relative to 3. Examination
已经鉴定出一系列有效的HIV蛋白酶非肽抑制剂。利用与HIV蛋白酶结合的化合物3的结构,设计并制备了双叔酰胺抑制剂9。发现化合物9的效力是3的约17倍,并且9的蛋白质-配体复合物的结构显示抑制剂相对于3以反向结合模式结合。对9的蛋白质-配体复合物的检查表明有几种修饰在P1和P1'的口袋中。通过这些修饰,有可能将抑制剂的活性再提高100倍,从而突出了晶体学反馈在抑制剂设计中的实用性。发现这些化合物在细胞培养中具有良好的抗病毒活性,对HIV蛋白酶具有选择性,并且可以在三种动物模型中口服获得。
