Description and Uses

Checkpoint kinase 1 (Chk1) regulates S and G₂-M phase cell cycle checkpoints in response to DNA damage. CHIR124 is a cell-permeable, quinolone-based inhibitor of Chk1 (IC₅₀ = 0.3 nM in vitro). It demonstrates high selectivity for Chk1 by displaying inhibitory values 2,000-fold higher against Chk2 (IC₅₀ = 0.7 μM). In synergy with topoisomerase I poisons or ionizing radiation, CHIR124 can inhibit the growth of p53-mutant solid tumor cells both in vitro and in a xenograft model, potentiating tumor apoptosis.

CHIR 124 is a cell-permeable molecule with a quinolone-based structure. It inhibits checkpoint kinase 1 (Chk1) which regulates S and G2-M cekk cycle checkpoints in response to DNA damage. Application towards inhibition of tumor cell growth.
