Application

Roscovitine has been used:
  • an inhibitor of p34cdc2/cyclin B kinase to preculture porcine oocytes
  • as a supplement in TCM199 medium for in vitro prematuration of cumulus-oocyte complexes (COCs) of adult goats
  • in astrocyte conditioned media as an inhibitor of cyclin-dependent kinase 5 (CDK5)
  • as a CDK2 inhibitor in culture media to treat hESCs

Biochem/physiol Actions

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

Discover Bioactive Small Molecules for Apoptosis

Apoptosis, or programmed cell death (PCD), is a selective process for the removal of unnecessary, infected or transformed cells in various biological systems. As it plays a role in the homeostasis of multicellular organisms, apoptosis is tightly regulated through two principal pathways by a number of regulatory and effector molecules.

Discover Bioactive Small Molecules for Cell Cycle Research

n proliferating cells, the cell cycle consists of four phases. Gap 1 (G1) is the interval between mitosis and DNA replication that is characterized by cell growth. Replication of DNA occurs during the synthesis (S) phase, which is followed by a second gap phase (G2) during which growth and preparation for cell division occurs. Together, these three stages comprise the interphase phase of the cell cycle. Interphase is followed by the mitotic (M) phase.
