Abstract

A series of pyrimidodiazepines was identified as potent Polo-like kinase 1 (PLK1) inhibitors. The synthesis and SAR are discussed. The lead compound 7 (RO3280) has potent inhibitory activity against PLK1, good selectivity against Other kinases, and excellent in vitro cellular potency. It showed strong antitumor activity in xenograft mouse models.
