In vivo SCH66336 inhibits HTBI77 human lung carcinoma xenograft growth in nude mice in a dose-dependent fashion. [1] SCH66336 dosed at 50 mg/kg p.o. bid by oral gavage inhibits tumor growth with up to 69% growth inhibition after 21 days of treatment in NOD/SCID mice bearing s.c. flank XEN01, XEN05 or XEN08 GBM xenografts. [3]
Kinase Assay FPTactivity is determined by measuring the transfer of [3H]farnesyl from [3H]farnesyl PPi to trichloroacetic acid-precipitable Ha-Ras-CVLS. GGPT-1 activity is similarly determined using [3H]geranylgeranyl diphosphate and Ha-Ras-CVLL as substrates[1].
Cell Research
The cells are seeded in 96-well cell-culture cluster plates at a density that allowed control cultures to grow exponentially for 5 days. After 24 hours, the cells are treated with different concentrations of SCH66336. SCH66336 is dissolved in DMSO. Control cultures received the same amount of DMSO as the treated cultures do. Cell numbers are estimated after 5 days of treatment by SRB assay. The percentage of growth inhibition is calculated by using the equation: percentage growth inhibition = (1 − At/Ac) × 100, where At and Ac represent the absorbance in treated and control cultures, respectively. The drug concentration causing a 50% cell growth inhibition (IC50), is determined by interpolation from dose-response curves.(Only for Reference)

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
