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
