Description NIBR-0213, a potent and selective S1P(1) antagonist, has efficacy in experimental autoimmune encephalomyelitis.
Targets&IC50 S1P1:8.5 nM(GTPγ35S,mouse), S1P1:2.5 nM(Ca2+ mobilization), S1P1:2.3 nM(GTPγ35S,rat), S1P1:2.0 nM(GTPγ35S,human)
In vitro In Ca2+?mobilization assays, NIBR-0213 displayed an inhibitory activity on hS1P1?with an IC50?of 2.5?nM whereas it was inactive (IC50?> 10?μM) on S1P2, S1P3, and S1P4. In GTPγ35S assays, NIBR-0213 displayed potent and comparable potency on human and rat S1P1?(IC50?of 2.0?nM and 2.3?nM, respectively), whereas on mouse S1P1?a slightly reduced IC50?of 8.5?nM was?measured. NIBR-0213 showed an ~3,000-fold selectivity against human S1P5?in the GTPγ35S assay (Figure?3A). On S1P4, a weak agonistic activity was detected with an EC50?of 245?nM. Schild plot analysis indicated that NIBR-0213 is a competitive S1P1?antagonist with a calculated Kd?of 0.37?± 0.031?nM[2].
In vivo NIBR-0213 increased in a dose-dependent manner the leakage of?plasma proteins?into lung parenchyma, as measured by the increase in EBD in lung tissues at 6?hr posttreatment (time of Emax on PBL). A maximum of 4–5-fold EBD increase versus vehicle controls was observed with 0.3?mg/kg. An ED50?of ~0.1?mg/kg could be estimated, i.e., in the range of the ED50?for the effects on PBL counts[2]. NIBR-0213 given orally at 30 mg/kg to rats reduced the PBL counts by 75%–85% within 14 hr and maintained this effect up to 24 hr posttreatment[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.
