In this funding period we have extended our studies outlined in Tasks 1 and 2 of the approved Statement of Work with the development of a novel and versatile strategy to synthesize focused chemical libraries against DNA repair enzymes. A high-throughput screen of this focused library yielded several potent and specific inhibitors of human uracil DNA glycosylase. Investigations into the effects of inhibiting uracil DNA glycosylase with these small molecules on the cytotoxicity and mechanism of 54luorouracil are ongoing. This work has resulted in two publications during this funding period.
