YKL-5-124

YKL-5-124 is a novel potent, selective, and covalent CDK7 inhibitor (IC50=53.5 nM), inhibits CDK7/CycH/MAT1 enzymatic activity with IC50 of 9.7 nM; displays biochemical and cellular selectivity for CDK7 over structurally related kinases CDK12/13, and no significant activity against CDK2 and CDK9 (IC50>1 uM); targets and forms a covalent bond with CDK7- cysteine 312 (C312); inhibition of CDK7 by YKL-5-124 elicits a transcriptional signature distinct from that of THZ1, shows no discernible effect on RNA Pol II CTD phosphorylation; recapitulate THZ1-mediated effects on gene expression and CTD phosphorylation when combined with CDK12/13 inhibitor THZ531.
