CHIR-124是一种新型有效的Chk1抑制剂,无细胞试验中IC50为0.3 nM。比作用于Chk2选择性高2000倍,比作用于CDK2/4和Cdc2活性高500到5000倍。
Information
CHIR-124 is a novel and potentChk1inhibitor withIC50of 0.3 nM in a cell-free assay. It shows 2,000-fold selectivity against Chk2, 500- to 5,000-fold less activity against CDK2/4 and Cdc2.
In vitro
CHIR-124 is a quinolone-based small molecule that is structurally unrelated to other known inhibitors of Chk1. CHIR-124 interacts synergistically with topoisomerase poisons (e.g., Camptothecin or SN-38) in causing growth inhibition in a variety of cancer cell lines, including breast carcinoma (MDA-MB-231 and MDA-MB-435) and colon carcinoma (SW-620 and Colo205), all of which contains the mutant p53 gene. CHIR-124 abrogates the SN-38-induced S and G2-M checkpoints and potentiates apoptosis in MDA-MD-435 breast cancer cells. The abrogation of the G2-Mcheckpoint and induction of apoptosis by CHIR-124 are enhanced by the loss of p53. CHIR-124 also potently targets other kinases such as PDGFR and Flt3 with IC50 of 6.6 nM and 5.8 nM, respectively.
In vivo
CHIR-124 potentiates the growth inhibitory effects of Irinotecan by abrogating the G2-M checkpoint and increasing tumor apoptosis in an orthotopic breast cancer xenograft model.
