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

Cyclin-dependent kinases (CDKs) are key regulators of the cell cycle and RNA polymerase II transcription. Several pharmacological CDK inhibitors (PCIs) are currently in clinical trials as potential cancer therapeutics since CDK hyperactivation is detected in the majority of neoplasias. Within

Tumorigenesis in different segments of the intestinal tract involves tissue-specific oncogenic drivers. In the colon, complement component 3 (C3) activation is a major contributor to inflammation and malignancies. By contrast, tumorigenesis in the small intestine involves fatty acid-binding protein 1

Overexpression of the MYC transcription factor causes its widespread interaction with regulatory elements in the genome but leads to the up- and down-regulation of discrete sets of genes. The molecular determinants of these selective transcriptional responses remain elusive. Here, we
