摘要

We have demonstrated that quinazolin-4 (3H)-one, a nicotinamide (NI) mimic with PARP-1 inhibitory activity in the high micromolar range (IC50= 5.75 μM) could be transformed into highly active derivatives with only marginal increase in molecular weight. Convenient one to two synthetic steps allowed us to explore extensive SAR at the 2-, and 5-through 8-positions of the quinazolin-4 (3H)-one scaffold. Substitutions at the 2-and 8-positions were found to ...
