Product Overview

Alternative Names
Tozasertib VX 680

MK 0457 is a potent pan-Aurora kinase inhibitor but favors Aurora A (Ki = 0.6 nM) over Aurora B (Ki = 18 nM) or Aurora C (Ki = 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.
