Description SNAP-94847 is a selective and competitive MCH1 receptor (MCH1-R) antagonist (Ki: 2.2 nM). It has anxiolytic and antidepressant activity and reduces food intake in mice.
Targets&IC50 MCH1 receptor:2.2 nM (Ki, cell free)
In vitro SNAP-94847 showed a favorable combination of MCH1 receptor affinity (Ki: 2.2 nM) and human R1A receptor (>80-fold) and D2 (>500-fold) selectivity [1].
In vivo SNAP-94847 (10 mg/kg, p.o.) had no effect on basal water consumption measured over 2 h: vehicle-treated (2.0 mL); 16g-treated (2.3 mL). MCH-evoked water intake was inhibited significantly by SNAP-94847 at doses of 1.0, 2.5, and 10 mg/kg [1]. BALB/c mice treated for 21 days with fluoxetine or SNAP 94847 (20 mg/kg/day) showed marked increases in quinpirole-induced locomotor activity, with the onset of hyper-locomotion appearing earlier in the time course after SNAP 94847 compared to fluoxetine. Administration of either compound for 7 days was also sufficient to augment the quinpirole response in BALB/c mice [2]. The intra-locus coeruleus and intracerebroventricular injections of melanin-concentrating hormone and chronic injections of corticosterone increased immobility time in the forced swim test and decreased sucrose preference in the sucrose preference test. All these depressive-like behaviors were reversed by an intra-locus coeruleus microinjection of SNAP-94847 [3].
Animal Research Chronically treated Sprague–Dawley rats were administered fluoxetine (18 mg/kg/day) or SNAP 94847 (20 mg/kg/day) via oral gavage in 20% beta-cyclodextrin for 2 weeks (1 injection, 6 h into light cycle). For acute treatment, drugs were given orally in 20% betacyclodextrin 1 h before testing. On each test day, locomotor activity was recorded during a 60 min habituation to the novel locomotor cage, after which the rats were administered quinpirole (0.3 mg/kg, i.p.) and returned immediately to the cage, where locomotor activity was measured for an additional 180 min. In each case-control animals were administered the corresponding vehicle, without drug [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

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
