Description

Biochem/physiol Actions

Potent and selective pan-aurora kinase inhibitor that binds aurora kinase in the DFG-in conformation and exhibits anticancer efficacy in vitro and in vivo.

SNS-314 is a potent pan-aurora kinases inhibitor (IC50 = 9/31/3 nM against aurora kinase A/B/C or aurora 2/1/3) that binds aurora kinase in the DFG-in conformation and exhibits great selectivity against a panel of 219 kinases (>5-, >12-, >14-, >15-, >82-, >84-fold selectivity for aurora A over TrkB, TrkA, Flt4, Fms, DDR2, Axl, respectively; >100-fold selectivity over c-Raf and the remaining kinases). SNS-314 downregulates cellular histone H3 Ser10 (HH3 Ser10) phosphorylation (IC50 <16 nM) and exhibits potent antiproliferation activity in HCT116 human colon cancer cultures in vitro (IC50 = 5 nM). When applied in vivo, HCT116 likewise reduces pHH3 (Ser10) level in tumor tissue (by 75-100% 6 hrs post 50 mg/kg i.p. dosage) and suppresses tumor growth (100 mg/kg/day, 5 days on, 9 days off; 150 mg/kg biweekly x3), as well as potentiates docetaxel antitumor efficacy in a mouse HCT116 xenograft model in vivo (42.5 mg SNS-314/kg followed by 10 mg docetaxel/kg 24 hr later; biweekly x3).
