R&D Systems™ Adavosertib

Adavosertib is a potent and selective Wee1 inhibitor (IC50 = 5.2 nM). In a panel of 223 serine/threonine or tyrosine kinases, Adavosertib is highly selective for Wee 1 over all except 8 kinases. In particular Adavosertib shows >100-fold selectivity over human Myt1. Adavosertib blocks CDC2Y15 phosphorylation and Gemcitabine (Cat. No. 3259)-induced DNA damage checkpoint, leading to premature mitotic entry and apoptosis in p53-deficient tumor cell lines. Adavosertib also potentiates the cytotoxic effects of Pemetrexed (Cat. No. 6185), Doxorubicin (Cat. No. 2252), Camptothecin (Cat. No. 1100) and Mitomycin C (Cat. No. 3258) in vitro. Adavosertib synergizes with gemcitabine to achieve tumor regressions, selectively in p53-deficient pancreatic cancer xenografts.
