Abstract
A new class of PARP-1 inhibitors, namely substituted fused uracil derivatives were synthesised. Starting from a derivative with an IC(50)=2microM the chemical optimisation program led to compounds with more than a 100-fold increase in potency (IC(50)<20nM). Additionally, physicochemical and pharmacokinetic properties were evaluated. It could be shown that compounds bearing a piperazine or phenyl substituted betaAla-Gly side chain exhibited the best overall profile.
