Quinazolin-2-ylamino-quinazolin-4-ols as novel non-nucleoside inhibitors of bacterial DNA polymerase III.

High throughput screening led to the discovery of a novel series of quinazolin-2-ylamino-quinazolin-4-ols as a new class of DNA polymerase III inhibitors. The inhibition of chromosomal DNA replication results in bacterial cell death. The synthesis, structure-activity relationships and functional activity are described.
