Design and Optimization of Tricyclic Phtalimide Analogues as Novel Inhibitors of HIV-1 Integrase
摘要:
Human immunodeficiency virus type-1 integrase is an essential enzyme for effective viral replication and hence a valid target for the design of inhibitors. We report here on the design and synthesis of a novel series of phthalimide analogues as integrase inhibitors. The short synthetic pathway enabled us to synthesize a series of analogues with a defined structure diversity. The presence of a single carbonyl-hydroxy-aromatic nitrogen motif was shown to be essential for the enzymatic activity and this was confirmed by molecular docking studies. The enzymatically most active compound from this series is 743,4-dichlorobenzyl)-5,9dihydroxypyrrolo[3,4-g]quinoxaline-6,8-dione (151) with an IC50 value of 112 nM on the HIV-1 integrase enzyme, while ((7-(4-chlorobenzyl)-5,9-dihydroxy-pyrrolo[3,4-g]quinoxaline-6,8-dione (15k)) showed an EC50 of 270 nM against HIV-1 in a cell-based assay.

method for the synthesis of cyclicimidesfrom nitriles and diols was developed. The method utilizes a Ru-catalyzed transfer-hydrogenation reaction in which the substrates, diols, and nitriles are simultaneously activated into lactones and amines in a redox-neutral manner to afford the corresponding cyclicimides with evolution of H2 gas as the sole byproduct. This operationally simple and catalytic
