Description: Seliciclib, also known as roscovitine and CYC202, is a n orally bioavailable, small-molecule cyclin-dependent kinase (CDK) inhibitor with potential proapoptotic and antineoplastic activities. Seliciclib primarily inhibits CDK2/E, CDK2/A, CDK7 and CDK9 by competing for their ATP binding sites, leading to a disruption of cell cycle progression. In addition, this agent appears to interfere with CDK-mediated phosphorylation of the carboxy-terminal domain of RNA polymerase II, inhibiting RNA polymerase II-dependent transcription, which may result in the down-regulation of antiapoptotic proteins such as induced myeloid leukemia cell differentiation protein Mcl-1.

Additional Information

Phase I trial of Selicilib: Fifty-six patients received a total of 218 cycles of seliciclib. Dose-Limiting Toxicities (DLT) consisting of nausea, vomiting, asthenia and hypokalaemia occurred at 1600 mg bid for schedule A and in schedule C, DLT of hypokalaemia and asthenia occurred at 1800 mg bid. The evaluation of longer treatment duration in schedule B was discontinued because of unacceptable toxicity at lower doses. Other adverse events included transient serum creatinine increases and liver dysfunctions. Pharmacokinetic data showed that exposure to seliciclib and its carboxylate metabolite increased with increasing dose. Soluble cytokeratin 18 fragments allowed monitoring of seliciclib-induced cell death in the blood of patients treated with seliciclib at doses above 800 mg/d. One partial response in a patient with hepatocellular carcinoma and sustained tumour stabilisations were observed. The MTD and RD for seliciclib are 1250 mg bid for 5d every 3 weeks and 1600 mg bid for 3d every 2 weeks, respectively. ( Eur J Cancer. 2010 Dec;46(18):3243-50. ).
