Beschreibung
The Aurora kinases (A, B, and C) are a family of serine-threonine kinases that regulate various stages of mitotic function. With significant roles in cell cycle and cell division, Aurora kinase gene amplification and overexpression are linked to tumorigenesis. MK-0457 is a potent pan-Aurora kinase inhibitor but favors Aurora A (K_i = 0.6 nM) over Aurora B (K_i = 18 nM) or Aurora C (K_i = 4.6 nM). It shows selectivity against a panel of more than 190 different protein kinases. MK-0457 effectively inhibits proliferation of several different cell lines of clear cell renal carcinoma (IC₅₀s = <10 μM) and blocks the growth of tumors in a rodent model of cancer (80 mg/kg), inhibiting histone H3 phosphorylation and increasing apoptosis. By depleting Aurora activity, MK-0457 disrupts bipolar spindle formation during mitosis, arresting cell cycle progression at the G₂/M phase.

Definition
ChEBI: N-[4-[[4-(4-methyl-1-piperazinyl)-6-[(5-methyl-1H-pyrazol-3-yl)amino]-2-pyrimidinyl]thio]phenyl]cyclopropanecarboxamide is a N-arylpiperazine.
Biochem/physiol Actions
VX-680 is an ATP site-targeting potent aurora kinase inhibitor (Aurara A/B/C Ki(app) = 0.6/18/4.6 nM) that affects FLT3, BCR-Abl, BCR-Abl (T315I), Lck, ITK, Src, and Fyn only at higher concentrations (Ki(app) = 30, 30, 42, 80, 220, 350, 520 nM, respectively) and exhibits little inhibitory potency toward 52 other kinases (Ki(app) >1 μM). VX-680 exhibits potent antiproliferation activity in a wide variety of cancer cultures (IC50 from 15 to 113 nM) as a result of cell cycle arrest and apoptosis induction, as well as causes tumor retardation (by 98% on day 13; 75 mg/kg b.i.d i.p.; HL-60 in mice) and regression (2 mg/kg/h 3 d/wk i.v. infusion; HCT116 in rats) in vivo. Crystallography data reveal a tight association of VX-680 with a hydrophobic pocket present only in a closed, inactive kinase conformation, which forms the basis of its selectivity profile, including its activity toward wild-type and the Imatinib-resistant (T315I) Abl.
