Description Eplivanserin (SR-46349) is an effective and selective antagonist of 5-HT2A receptor with a Kd of 1.14 nM and an IC50 value of 5.8 nM in rat cortical membrane.
Targets&IC50 5-HT2 receptor:1.14 nM (ki), 5-HT2 receptor:5.8 nM (in rat cortical membrane)
In vitro Eplivanserin has inhibitory effects on rat cortex adrenergic α1 and α2, rat whole brain histammine H1, Na+ channel, and rat striatum dopamine D1 and D2, with IC50s of 3.4 μM, 1.0 μM, 5.0 μM, 39 μM, 9 μM and 28 μM, respectively. Eplivanserin displays >20-fold selectivity more selective for 5-HT2A than 5-HT2B and 5-HT2C with IC50s of 0.12 μM (Pig cortex 5-HT1C), 14 μM (Rat hippocampus 5-HT1A), and 16 μM (Rat stnatum 5-HT1B, Ox caudate nucleus 5-HT1D)[1].
In vivo In mice, Eplivanserin(0.097 mg/kg; i.p.) inhibits 5-HT2 receptor binding of [3H]ketanserin with an ED50 of 0.087 mg/kg[1]. In rats, SR 46349B (0.25-1 mg/kg; i.p.) blocks Cocaine-evoked hyperactivity following repeated Cocaine treatment[2].

Molecular Weight Calculator

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
