(-) -Enitociclib

(-) -Enitociclib ((R) -Enitociclib) is an enantiomer of Enitociclib (HY-103019E) with an optical rotation of (-) . Enitociclib is a selective CDK9 inhibitor and apoptosis inducer. Enitociclib inhibits CDK9 activity and reduces the phosphorylation of Ser2 in the carboxyl-terminal domain (CTD) of RNA polymerase Pol II, thereby downregulating the transcription of key oncogenes such as MYC and MCL1. Enitociclib has anti-proliferative activity targeting MYC+ lymphoma and multiple myeloma (MM) cells, and has synergistic effects with Bortezomib (HY-10227) and Lenalidomide (HY-A0003), and can be used in the research of hematological malignancies[1][2].
