(R)-CR8 trihydrochloride (CR8, (R)-Isomer trihydrochloride) is a CDK1/2/5/7/9 inhibitor that acts as a molecular glue degrader with neuroprotective activity and induces apoptosis.

Mevociclib (SY-1365) is a highly selective covalent inhibitor of CDK7, possessing therapeutic potential in both hematological and solid tumors.

THZ1-R is a non-covalent active analogue of THZ1, with the acrylamide group removed from THZ1, losing its ability to covalently bind to the C312 cysteine residue of CDK7. Its CDK7 inhibitory activity is weaker than that of THZ1.

1-NM-PP1 (PP1 Analog II) is a cell-permeable PP1 analog that acts as a potent and selective inhibitor of mutant kinases over their wild-type progenitors.

YKL-5-124, a potent, selective and covalent CDK7 inhibitor with an IC50 of 9.7 nM, 1300 nM and 3020 nM for CDK7/Mat1/CycH, CDK2 and CDK9 respectively, displays biochemical and cellular selectivity for CDK7 over CDK12/13.

Flavopiridol hydrochloride (MDL 107826A) is a synthetic N-methylpiperidinyl chlorophenyl flavone compound. As an inhibitor of cyclin-dependent kinase, alvocidib induces cell cycle arrest by preventing phosphorylation of cyclin-dependent kinases (CDKs) and by down-regulating cyclin D1 and D3 expression, resulting in G1 cell cycle arrest and apoptosis. This agent is also a competitive inhibitor of adenosine triphosphate activity.

THZ1 2HCl (THZ1 Dihydrochloride) is a selective, covalent, and allosteric inhibitor of CDK7 with an IC50 of 3.2 nM. THZ1 2HCl has antiproliferative effects on a variety of cancer cell lines.
