<p>Applications Roscovitine is a potent and selective inhibitor of cyclin-dependent kinases (CDKs). Roscovitine has been found to produce apoptosis in treated cancerous cells of non-small cell lung cancer (NSCLC) and other cancers. Studies show that Roscovitine displays increased anti-mitotic activity at the G1/S and G2/M phases of the cell cycle. Roscovitine maybe useful in the treatment of non-small cell lung cancer (NSCLC), leukemia, HIV infection, herpes simplex infection, and the mechanisms of chronic inflammation disorders.<br>References De Azevedo, W.F. et al.: Eur.
