| | FLAVOPIRIDOL HYDROCHLORIDE Usage And Synthesis |
| Description | Flavopiridol is an orally bioavailable inhibitor of cyclin dependent kinases (IC50s = ~100, ~100, ~100, and 300 nM for Cdk1, Cdk2, Cdk4, and Cdk7, respectively). It also inhibits TEFb, a complex composed of Cdk9 and cyclin T1, with a Ki value of 3 nM. Flavopiridol inhibits transcription of a CMV promoter in HeLa nuclear extract (IC50 = 34 nM), Tat-stimulated transcription of an HIV-1 promotor (IC50 = 7 nM), and HIV-1 replication in HEK239T cells (IC50 = <10 nM). In vivo, flavopiridol (5 mg/kg, i.p.) induces apoptosis and cyclin D1 depletion and delays tumor growth in an HN-12 head and neck carcinoma mouse xenograft model. It also suppresses synovial hyperplasia and joint destruction in a mouse model of collagen-induced arthritis. | | Chemical Properties | Yellow Powder | | Uses | An inhibitor of cyclin-dependent kinases; the (-)-cis form induces apoptosis in certain tumor cells. | | Uses | 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
| | Definition | ChEBI: A hydrochloride salt resulting from the formal reaction of equimolar amounts of alvocidib and hydrogen chloride. A cyclin-dependent kinase 9 (CDK9) inhibitor, it has been studied for the treatment of acute myeloid leukaemia, arthritis and atherosclerotic p
aque formation. | | Biochem/physiol Actions | 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). | | storage | Store at +4°C | | References | [1] G KAUR.
