Description

Application

Flavopiridol hydrochloride hydrate has been used:

• as a cyclin-dependent kinase 9 (CDK9) inhibitor to study its effects on histone H3 methylation at lysine 36 (H3K36) and deactivation of transcription in porcine fetal fibroblasts
• as an RNA polymerase inhibitor to study its effects on hepatic cells
• as RNA transcription inhibitor to study its effects on euchromatin coarsening in zebrafish embryo

Biochem/physiol Actions

Flavopiridol hydrochloride is a potent CDK (cyclin-dependent kinase), and a CDC25 phosphatase family inhibitor.

Flavopiridol is a semi-synthetic flavone obtained from Dysoxylum binectariferum that acts as an anti-tumor agent against several cancers. It also shows anti-cancer properties due to which it has been studied in the treatment of acute myeloid leukemia (AML).
