NS3861

NS3861
NS3861 is an agonist of nicotinic acetylcholine receptors (nAChRs) that binds with high affinity to heteromeric α3β4 and α4β2 nAChRs, displaying β-subunit preference and no activation at α4-containing receptors. The maximal efficacy of NS3861 depends on the ligand-binding domain, and a serine to threonine substitution in the principal subunit may explain the lack of activation at α4-containing receptors.

Description
NS3861 is an agonist of nicotinic acetylcholine receptors (nAChRs) that binds with high affinity to heteromeric α3β4 and α4β2 nAChRs, displaying β-subunit preference and no activation at α4-containing receptors. The maximal efficacy of NS3861 depends on the ligand-binding domain, and a serine to threonine substitution in the principal subunit may explain the lack of activation at α4-containing receptors.

α4β4 (4:1):1.2 μm(Ki), α3β2:1.6 μm(Ki), α3β4:1 μm(Ki), α4β4 (1:4):1.9 μm(Ki)
In vitro
NS3861 was found to activate wild-type α3β4 nAChRs (Figs. 3R and 4) but did not activate wild-type α4β2. Whereas NS3861 was a partial agonist at α3β4, it proved to be a full agonist at α3β2 albeit with ~10-fold lower potency consistent with the binding affinities. Efficacy at the α3/α4 + β4/β2 receptor was almost identical to that of wild-type α3β4, whereas no efficacy could be seen at α4/α3 + β2/β4[1].

In Vivo Formulation Calculator (Clear solution)

Please enter your animal experiment information in the following box and click Calculate to obtain the mother liquor preparation method and in vivo formula preparation method:
TargetMol | Animal experimentsFor example, your dosage is 10 mg/kg Each animal weighs 20 g, and the dosage volume is 100 μL . TargetMol | Animal experiments A total of 10 animals were administered, and the formula you used is 5% TargetMol | reagent DMSO+30% PEG300+5% Tween 80+60% ddH2O. So your working solution concentration is 2 mg/mL。
Mother liquor preparation method: 2 mg of drug dissolved in 50 μL DMSOTargetMol | reagent (mother liquor concentration of 40 mg/mL), if you need to configure a concentration that exceeds the solubility of the product, please contact us first.
Preparation method for in vivo formula: Take 50 μL DMSOTargetMol | reagent main solution, add 300 μLPEG300TargetMol | reagent mix well and clarify, then add 50 more μL Tween 80, mix well and clarify, then add 600 more μLddH2OTargetMol | reagent mix well and clarify
For Reference Only. Please develop an appropriate dissolution method based on your laboratory animals and route of administration.
