Design and synthesis of novel β-diketo derivatives as HIV-1 integrase inhibitors.

A series of novel β-diketo derivatives which combined the virtues of 1,3-diketo, 1,2,3-triazole and polyhydroxylated aromatics moieties, were designed and synthesized as potential HIV-1 integrase (IN) inhibitors and evaluated their inhibition to the strand transfer process of HIV-1 integrase. The result indicates that 3,4,5-trihydroxylated aromatic derivatives exhibit good inhibition to HIV-1 integrase, but dihydroxylated aromatic derivatives and corresponding methoxy aromatic derivatives appear little inhibition to HIV-1 integrase.
