Description
Sources: https://www.ncbi.nlm.nih.gov/pubmed/15958589 | https://www.ncbi.nlm.nih.gov/pubmed/26987072 | https://www.ncbi.nlm.nih.gov/pubmed/19938906

Seliciclib (CYC202, R-roscovitine) is a second-generation orally available cyclin-dependent kinases (CDKs) inhibitor that competes for ATP binding sites on these kinases. It is a direct inhibitor of cyclin CDK2/E, CDK2/A and it has inhibitory effects on cyclin H/CDK7, CDK5, and CDK9. CDKs are enzymes that are central to the process of cell division and cell cycle control and play pivotal roles in cancer cell growth and DNA damage repair. Seliciclib exerts an anti-proliferative effect via several key mechanisms: selective downregulation of proliferative and survival proteins and upregulation of p53, leading to growth arrest or apoptosis. The second one is decreasing phosphorylation of Rb and modulating E2F transcriptional activity leading to growth arrest or apoptosis. Seliciclib is currently in phase II clinical trial as a drug candidate for the treatment of Cushing's disease and as a potential therapeutic agent for the treatment of cystic fibrosis (CF). In addition, it is in Phase II trials for non-small cell lung cancer and nasopharyngeal carcinoma.

Sample Use Guides

In Vivo Use Guide

Cushing Disease: R-roscovitine 400 mg oral administration twice daily for 4 days every week for total of 4 weeks. cystic fibrosis: 200 or 400 mg roscovitine (8) or placebo (4) once daily for 4 cycles of 7 days (4 days "on" and 3 days "off")

Route of Administration: Oral

In Vitro Use Guide

CDK2 inhibitors have been proposed as effective anti-cancer therapeutics. It was shown that CYC202 (R-roscovitine) is a potent inhibitor of recombinant CDK2/cyclin E kinase activity (IC(50) = 0.10 microM) with an average cytotoxic IC(50) of 15.2 microM in a panel of 19 human tumour cell lines, and was also demonstrated selectivity for rapidly proliferating cells over non-proliferating cells. A study of the cell cycle effects of CYC202 in Lovo colorectal carcinoma cells showed that the major effect was not the predicted arrest in one part of the cycle, but rather an induction of cell death from all compartments of the cell cycle.
