摘要:
Optimization studies using an HIV RNase H active site inhibitor containing a 1-hydroxy-1,8-naphthyridin-2(1H)-one core identified 4-position substituents that provided several potent and selective inhibitors. The best compound was potent and selective in biochemical assays (IC(50) = 0.045 mu M, HIV RT RNase H; 13 mu M, HIV RT-polymerase; 24 mu M, HIV integrase) and showed antiviral efficacy in a single-cycle viral replication assay in P4-2 cells (IC(50) = 0.19 mu M) with a modest window with respect to cytotoxicity (CC(50) = 3.3 mu M).
