| | CHIR-124 Usage And Synthesis |
| Description | 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. | | Uses | 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. | | references | [1]. tse an, rendahl kg, sheikh t, et al. chir-124, a novel potent inhibitor of chk1, potentiates the cytotoxicity of topoisomerase i poisons in vitro and in vivo. clinical cancer research, 2007, 13(2): 591-602.
