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.

How to use

In Vitro:

Roscovitine displays high efficiency and high selectivity towards some cyclin-dependent kinases with IC50 of 0.65, 0.7, 0.7 and 0.16 μM for cdc2/cyclin B, cdk2/cyclin A, cdk2/cyclin E and cdk5/p53, respectively. Roscovitine reversibly inhibits the prophaselmetaphase transition in the micromolar range of starfish oocytes and sea urchin embryos, inhibits in vitro M-phase-promoting factor activity and in vitro DNA synthesis in Xenopus egg extracts, and suppresses the proliferation of mammalian cell lines with an average IC50 of 16 μM. In mesangial cells, Roscovitine results in a dose-dependent reduction of CDK2 activity that at concentrations of 7.5, 12.5 and 25 mM, Roscovitine causes a 25, 50% and 100% decrease in CDK2 activity, respectively. A recent study shows that Roscovitine inhibits cdk5 kinase activity, cell proliferation, multicellular development, and cdk5 nuclear translocation in Dictyostelium discoideum, without affecting the expression of cdk5 protein during axenic growth.

In Vivo:

Roscovitine, at a dose of 50 mg/kg, significantly inhibits growth of The Ewing's sarcoma family of tumors (ESFT) xenografts. Roscovitine enhances the antitumor effect of doxorubicin without increased toxicity with a mechanism that involves cell cycle arrest rather than apoptosis in nude mice bearing established MCF7 xenografts.
