Substituted 2-pyrrolinone inhibitors of HIV-1 integrase

The β-diketoacid class of HIV-1 integrase (IN) inhibitors represent the first potent class of compounds specific for the strand transfer catalytic activity of the viral enzyme. Previously, utilizing a β-diketoacid pharmacophore as a search query, we identified a substituted 2-pyrrolinone with modest IN inhibitory activity from a database of small-molecules [Dayam, R.; Sanchez, T.; Neamati, N. J. Med. Chem.2005, 48, 8009]. In efforts to optimize this class of IN inhibitors, we carried out a structure–activity relationship analysis around the 2-pyrrolinone core. Here, we present a new class of 2-pyrrolinone IN inhibitors.
