Naphthyl phosphoramidate derivatives of BVdU as potential anticancer agents: design, synthesis and biological evaluation.

ABSTRACT

The phosphoramidate technology we have developed has been recently applied to BVdU, leading to NB1011 (NewBiotics Inc., California), a novel potential anticancer compound recently entered into phase 2 of the clinical trials for colon cancer. We report in this work a new series of derivatives containing naphthol as aryl masking group on the phosphate moiety, which has shown a significant increase in anticancer activity in preliminary biological evaluations.
