Synonyms: AZD-4573 | AZD4573 | compound 24 [PMID: 33306391]
PDB Ligand
Compound class: Synthetic organic
Comment: AZD4573 is a potent inhibitor of cyclin dependent kinase 9 (CDK9), that was designed for potential to treat haematological malignancies [1-3]. Inhibition of CDK9 disrupts the expression of cancer-promoting genes such as MCL-1, and induces apoptosis. The chemical structure of AZD4573 matches that of the INN zemirciclib (proposed INN list 130, Feb. 2024).
