Biological Description
Chemical Properties
Storage & Solubility Information
Description Erismodegib diphosphate is an effective and selective Smo antagonist (IC50: 1.3 nM and 2.5 nM for mouse and human Smo in a binding assay, respectively).
Targets&IC50 hSmo:2.5 nM (IC50), mSmo:1.3 nM (IC50)
In vitro Erismodegib diphosphate, a small molecule, clinically investigated SMO inhibitor. Erismodegib diphosphate is used alone and in combination with Nilotinib, inhibits the Hh pathway in CD34+ chronic phase (CP)-chronic myeloid leukaemia (CML) cells, reducing the number and self-renewal capacity of CML leukaemia stem cell (LSC). In a similar fashion to cyclopamine, Erismodegib interacts directly with SMO, to reduce the expression of downstream Hh signaling targets. The IC50 values for Erismodegib diphosphate for the major human CYP450 drug-metabolizing enzymes are greater than 10 μM. Primary CD34+ CP-CML cells are cultured in serum-free media (SFM)±Erismodegib for 6, 24, and 72 hours (h). At 72 h, while there is variability between the biological samples, GLI1 is obviously downregulated following exposure to Erismodegib (10 nM; 0.78-fold and 100 nM; 0.73-fold, respectively (p<0.01)[2].
In vivo Erismodegib diphosphate is a weak base with a measured pKa of 4.2 and exhibits relatively poor aqueous solubility. Erismodegib diphosphate demonstrates dose-related antitumor activity after 10 days of oral administration of a suspension of the diphosphate salt, in the subcutaneous Ptch+/-p53-/- medulloblastoma allograft mouse model. Bone marrow cells and spleen cells from a subset of treated mice are transplanted into secondary recipient mice. Erismodegib diphosphate (5 mg/kg/day; once daily) obviously inhibits tumor growth, corresponding to a T/C value of 33% (p<0.05 as compared to vehicle controls). Erismodegib affords 51 and 83% regression respectively when dosed at 10 and 20 mg/kg/day qd [1]. Transplantation of either bone marrow (BM) or spleen cells from mice treated with Erismodegib diphosphate+ Nilotinib results in reduced white cell count (WCC) and reduces leukaemia development in secondary recipients compared to Erismodegib or Nilotinib alone[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
