Synonym: 2-(R)-[[9-(1-Methylethyl)-6-[(phenylmethyl)amino]-9H-purin-2-yl]amino]-1-butanol, 6-(Benzylamino)-2(R)-[[1-(hydroxymethyl)propyl]amino]-9-isopropylpurine



Biochem/physiol Actions

Roscovitine is a potent, selective inhibitor of cyclin-dependent kinases.

Roscovitine is a purine derived inhibitor. It stimulates apoptosis in cancer cells. It has inhibitory action on mitogen activated protein kinase (MAPK) and M-phase promoting factor (MPF) kinase activity. Roscovitine is known to arrest meiosis and thus, prevent embryonic development.
