Cdk4 inhibitor III   Click here for help

GtoPdb Ligand ID: 5952

Synonyms: ryuvidine
Compound class: Synthetic organic
Comment: CDK4 inhibitor III (ryuvidine), as its name suggests was originally reported as a selective inhibitor of CDK4, albeit a weak inhibitor [6]. However, to date (October 2018) there is no published data showing cellular inhibition of CDK4 by this compound, but some evidence of action at another target(s) that regulates the S phase of the cell cycle has been reported [5]. This latter effect may be due to CDK4 inhibitor III-induced inhibition of the lysine methyltransferase SETD8 [2,4].
