Biochem/physiol Actions

CHIR124 is a potent and selective inhibitor of checkpoint kinase 1 (Chk1)( IC50 = 0.3 nM) that produces G2-M abrogation which induces chemosensitisation. It also inhibits PDGFR and FLT3 (IC50 = 6.6 nM and 5.8 nM respectively). CHIR-124 inhibits Pgp activity in multidrug-resistant cell lines KB-V1 and A2780-Pac-Res.

Combination of cytotoxic therapy with emerging DNA damage response inhibitors (DDRi) has been limited by tolerability issues. However, the goal of most combination trials has been to administer DDRi with standard-of-care doses of chemotherapy. We hypothesized that mechanism-guided treatment scheduling
