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

Flavopiridol, a pan-cyclin-dependent kinase (CDK) inhibitor, was recently identified as an effective antitumor agent for several cancers. We investigated the antitumor effect of flavopiridol on cholangiocarcinoma (CCA), in vitro and in vivo. A methylthiotetrazole assay revealed that the proliferation of

Genome-wide profiling of nascent RNA has become a fundamental tool to study transcription regulation. Unlike steady-state RNA-sequencing (RNA-seq), nascent RNA profiling mirrors real-time activity of RNA polymerases and provides an accurate readout of transcriptome-wide variations. Some species of nuclear RNAs
