formation in infected C8166 cells, with no evidence of cytotoxicity. The compounds showed no activity against other aspartyl proteinases (renin, pepsin, and cathepsin D). Structure-activity relationships support a symmetrical interaction with the enzyme. Pharmacokinetic evaluation of the ethylamide 3 revealed it was subject to rapid plasma clearance and had low oral bioavailability.
通过随机筛选将C2对称二酯1鉴定为HIV-1蛋白酶的新型抑制剂。这导致了从容易获得的青霉素制备一系列相关的更有效的酰胺。许多化合物在感染HIV-1的MT-4细胞中显示出有效的抗病毒活性,并具有在感染的C8166细胞中抑制合胞体形成的能力,而没有细胞毒性的证据。该化合物对其他天冬氨酰蛋白酶(肾素,胃蛋白酶和组织蛋白酶D)无活性。结构-活性关系支持与酶的对称相互作用。乙酰胺3的药代动力学评估表明,乙酰胺3血浆清除迅速,口服生物利用度低。
