Biochem/physiol Actions

GSK461364 is an imidazotriazine derivate that inhibits polo-like kinase 1 (Plk1) in a potent, reversible, ATP-competitive, and highly selective manner (Kiapp <0.5 nM vs. 0.86 μM for Plk2 and 200 μM for Plk3; ATP Kmapp = 16 μM), exhibiting much reduced or little potency toward a panel of 262 kinases. GSK461364A inhibits the growth of various cancer cultures (IG50 <100 nM) as a result of either growth arrest (cytostasis) or cytotoxicity in vitro and effectively suppresses the expansion of various human tumor exnografts in mice in vivo (25 or 50 mg/kg i.p. q2dx12).

Polo-like kinase 1 (Plk1) is a conserved serine/threonine kinase that plays an essential role in regulating the many processes involved in mitotic entry and progression. In humans, Plk1 is expressed primarily during late G(2) and M phases and, in conjunction

Few therapeutic strategies exist for the treatment of metastatic tumor cells in the brain because the blood-brain barrier (BBB) limits drug access. Thus the identification of molecular targets and accompanying BBB permeable drugs will significantly benefit brain metastasis patients. Polo-like
Yan Degenhardt et al.
Molecular cancer therapeutics, 9(7), 2079-2089 (2010-06-24)
Polo-like kinases are a family of serine threonine kinases that are critical regulators of cell cycle progression and DNA damage response. Predictive biomarkers for the Plk1-selective inhibitor GSK461364A were identified by comparing the genomics and genetics of a panel of
