thz1

Description: THZ1 is a novel, potent, selective and covalent CDK7 inhibitor with an IC50 of 3.2 nM. It has exceptional ability to target a remote cysteine residue located outside of the canonical kinase domain, providing an unanticipated means of achieving selectivity for CDK7. THZ1 covalently modifies CDK7 by targeting C312 residue outside of the kinase domain, providing an unanticipated means of achieving covalent selectivity. THZ1 potently inhibits proliferation of Jurkat and Loucy T-ALL cell lines with IC50 values of 50nM and 0.55nM, respectively. In the kinase binding assay, THZ1 shows a good binding affinity with IC50 value of 3.2nM.
