Design and synthesis of novel pyrimidone analogues as HIV-1 integrase inhibitors

A series of novel pyrimidone analogues have been designed and synthesized as HIV-1 integrase (IN) inhibitors. This study demonstrated that introducing a substituent in the N1-position of the pyrimidone scaffold does not significantly influence IN inhibitory activity. Molecular docking studies showed these compounds could occupy the IN active site and form pi–pi interactions with viral DNA nucleotides DC16 and DA17 to displace reactive viral DNA 3′OH and block intasome activity.
