Storage & Solubility Information
Description SCH-1473759 is an inhibitor of the aurora (IC50s: 4 and 13 nM for Aurora A and B, respectively).
Targets&IC50 Aurora A:4 nM, Aurora B:13 nM
In vitro SCH-1473759 inhibits HCT116 cells proliferation (IC50: 6 nM). SCH 1473759 inhibits tumor cell lines from different tissues (breast, ovarian, prostate, lung, colon, brain, gastric, renal, skin, and leukemia). 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). SCH-1473759 directly binds to aurora A and B with Kds of 20 and 30 nM, respectively. It does not have significant activity (IC50>1000 nM) against 34 other kinases representing different families of the kinome. The most sensitive cell lines include A2780, LNCap, N87, Molt4, K562, and CCRF-CEM with IC50 values <5 nM [1][2].
In vivo SCH-1473759 shows good exposure in all species with the clearance being high in rodents and moderate in dog and monkey. SCH 1473759 dose- and schedule-dependent anti-tumor activity in four human tumor xenograft models. SCH-1473759 at a low dose of 5 mg/kg (i.p., 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(i.p., bid) is well-tolerated in an intermittent schedule (5 days on, 5 days off) and gave 69% TGI on day 16. The half-life is also moderate, but tissue distribution is high [1][2].

Molarity Calculator allows you to calculate the

  • Mass of a compound required to prepare a solution of known volume and concentration
  • Volume of solution required to dissolve a compound of known mass to a desired concentration
  • Concentration of a solution resulting from a known mass of compound in a specific volume
See Example

An example of a molarity calculation using the molarity calculator
What is the mass of compound required to make a 10 mM stock solution in 10 ml of water given that the molecular weight of the compound is 197.13 g/mol?
Enter 197.13 into the Molecular Weight (MW) box
Enter 10 into the Concentration box and select the correct unit (millimolar)
Enter 10 into the Volume box and select the correct unit (milliliter)
Press calculate
The answer of 19.713 mg appears in the Mass box


Calculator the dilution required to prepare a stock solution

Calculate the dilution required to prepare a stock solution
The dilution calculator is a useful tool which allows you to calculate how to dilute a stock solution of known concentration. Enter C1, C2 & V2 to calculate V1.

See Example

An example of a dilution calculation using the Tocris dilution calculator
What volume of a given 10 mM stock solution is required to make 20ml of a 50 μM solution?
Using the equation C1V1 = C2V2, where C1=10 mM, C2=50 μM, V2=20 ml and V1 is the unknown:
Enter 10 into the Concentration (start) box and select the correct unit (millimolar)
Enter 50 into the Concentration (final) box and select the correct unit (micromolar)
Enter 20 into the Volume (final) box and select the correct unit (milliliter)
Press calculate
The answer of 100 microliter (0.1 ml) appears in the Volume (start) box

Definitions of molecular mass, molecular weight, molar mass and molar weight:
Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed n the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)
Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol.
