SCH-1473759

CAS No. : 1094069-99-4

MCE 站：SCH-1473759

产品活性：SCH-1473759是多靶点的的极光激酶 (aurora) 抑制剂，对极光激酶A和B的IC₅₀ 值分别为4 和13 nM。

研究领域：Cell Cycle/DNA Damage  |  Epigenetics

作用靶点：Aurora Kinase

In Vitro: SCH-1473759 directly binds to aurora A and B with K_ds of 20 and 30 nM, respectively. SCH-1473759 also inhibits the Src family of kinases (IC₅₀<10 nM), Chk1 (IC₅₀=13 nM), VEGFR2 (IC₅₀=1 nM), and IRAK4 (IC₅₀=37 nM). It does not have significant activity (IC₅₀>1000 nM) against 34 other kinases representing different families of the kinome. SCH-1473759 inhibits HCT116 cells proliferation with an IC₅₀ 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 IC₅₀ values <5 nM.

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.
