A series of aromatic diketone derivatives were designed and synthesized as potential HIV-1 integrase (IN) inhibitors
and evaluated to determine their ability to inhibit the strand transfer process of HIV-1 integrase. The results indicate
that (Z)-1-(3-acetyl-2-hydroxy-4,6-dimethoxyphenyl)-3-hydroxy-3-(substituted)phenylprop-2-en-1-one (5a-5d) can
moderately inhibit HIV-1 integrase. The cyclization and condensation products (6a-6c and 7e-7f) of compounds 5a-5d
show poor inhibitory activity against HIV-1 integrase. The molecular docking results indicate that the different types of
compounds act on HIV-1 integrase in different ways, and these results can explain the differences in the inhibitory activities.
Keywords: Aromatic diketones, desmosdumotin D, HIV IN inhibitory activity, integrase inhibitor, molecular docking.
