Synthesis of symmetrical pseudopeptides as potential inhibitors of the human immunodeficiency virus-1 protease
摘要:
It is demonstrated that HIV-1 protease is essential for the assembly and infectivity of the acquired immunodeficiency syndrome (AIDS) virus. This protease is an aspartyl protease with a 2-fold symmetry axis. Potential inhibitors were synthesized and consisted of a spacer linking 2 peptidic chains. They had to satisfy the following constraints: a C-2 symmetry axis, a backbone similar to the peptidic substrates, and side-chains filling the subsites S-n...S'(n). The compounds were synthesized via peptidic synthetic methods and evaluated in an enzymatic test with HIV-1 protease. Several compounds displayed an inhibitory activity at 10 mu M. They possessed the spacers CO, CO-CO, CO-CH2-CHOH-CO and the terminal chain Phe-O-iC(4)H(9). However, the structural-variation-based optimization of these different compounds failed and no potent inhibitors were prepared.
