FLAVOPIRIDOL HYDROCHLORIDE Chemical Properties,Usage,Production

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 K_i 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
