SCH-1473759 hydrochloride is an aurora inhibitor with IC 50 s of 4 and 13 nM for aurora A and B, respectively. In Vitro SCH-1473759 directly binds to aurora A and B with K d s of 20 and 30 nM, respectively. SCH-1473759 also inhibits the Src family of kinases (IC 50 1000 nM) against 34 other kinases representing different families of the kinome. SCH-1473759 inhibits HCT116 cells proliferation with an IC 50 of 6 nM. SCH 1473759 inhibits tumor cell lines from different tissues (breast, ovarian, prostate, lung, colon, brain, gastric, renal, skin, and leukemia). The most sensitive cell lines includ A2780, LNCap, N87, Molt4, K562, and CCRF-CEM with IC 50 values In Vivo SCH-1473759 at a low dose of 5 mg/kg (ip, bid) is well-tolerated in a continuous dosing schedule and shows 50% tumor growth inhibition(TGI) on day 16. A higher dose of 10mg/kg(ip, bid) is well-tolerated in an intermittent schedule (5 days on, 5 days off) and gave 69% TGI on day 16. SCH-1473759 shows good exposure in all species with the clearance being high in rodents and moderate in dog and monkey. The half-life is also moderate, but the tissue distribution is high . SCH 1473759 dose- and schedule-dependent anti-tumor activity in four human tumor xenograft models. Further, the efficacy is enhanced in combination with taxanes and found to be most efficacious when SCH 1473759 is dosed 12-h post-taxane treatment. MCE has not independently confirmed the accuracy of these methods. They are for reference only. Animal administration Mice: Anti-tumor efficacy of SCH 1473759 dosed i.p. is evaluated in mice bearing established A2780 ovarian tumor xenografts. Three schedules are tested at their respective maximum tolerated doses: 10 mg/kg bid (twice daily), 20 mg/kg qd (daily), and 100 mg/kg day 0, 4, 7. Additionally, 60 mg/kg day 0, 4, 7 is tested . aladdin has not independently confirmed the accuracy of these methods. They are for reference only.
