THZ1(免费)产品是THZ1 is a potent, cell-permeable, and selective covalent CDK7 inhibitor (IC₅₀ = 3.2 nM) that preferentially diminishes transcription in cancer cells. It displays unprecedented ability to target a remote cysteine residue located outside of the canonical kinase domain, providing an unanticipated means of achieving selectivity for CDK7.
