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).

Mechanism Of Action and Pharmacodynamic Effects Click here for help
The CDK4/6 pathway is key to regulating cell growth in many types of human cancer [1,7-8], such as genetic subtypes of non-small cell lung cancer (NSCLC, [3,7,9], melanoma, Mantle cell lymphoma (MCL), and ovarian and breast cancers [3-4]. Inhibiting this pathway prevents cell cycle transition from G1 to S phase, induces cell senescence and in some cases results in apoptosis [3].
