GtoPdb Ligand ID: 7379

Synonyms: SCH727965
Immunopharmacology Ligand
Compound class: Synthetic organic
Comment: Dinaciclib is a potent cyclin-dependent kinase (CDK) inhibitor, inhibiting the CDK4 and 6 isoforms [6]. Dinaciclib has also been reported to interact with the acetyl-lysine recognition domain of the bromodomain testis-specific protein BRDT [6]. BRDT is a member of the BET family of bromodomain-containing proteins which are considered to be atypical kinases.

SARS-CoV-2: SARS-CoV-2 may regulate the host cell cycle to enhance viral replication, and in vitro phosphoproteomics analysis suggests that viral hijacking of the CDK signalling pathway may, at least in part, mediate this mechanism [2]. Pharmacological inhibition of the CDK pathway with dinaciclib has anti-SARS-CoV-2 activity in two model cells lines, A549-ACE2 cells (IC50 32 nM) and Vero E6 cells (IC50 127 nM).

Bioactivity Comments
In in vivo mouse studies, dinaciclib treatment causes tumour inhibition in a dose responsive manner [6], and is active against many human tumour cell lines in vitro [6].
