YKL-5-124 TFA(CAT: I045972) is a potent, selective, covalent, and irreversible inhibitor of CDK7 with IC₅₀ values of 53.5 nM (CDK7) and 9.7 nM (CDK7/Mat1/CycH). It demonstrates >100-fold selectivity for CDK7 over CDK9 and CDK2, and shows no activity against CDK12/13. YKL-5-124 induces strong cell-cycle arrest by inhibiting E2F-driven gene expression, while exerting minimal effects on RNA polymerase II phosphorylation. In HAP1 cells, it causes G1 and G2/M accumulation with S-phase reduction and suppresses CDK1 and CDK2 T-loop phosphorylation. YKL-5-124 TFA is a valuable chemical probe for dissecting CDK7-dependent transcriptional and cell-cycle control in cancer and mechanistic research.
