Varenicline
Based on 1 publication(s) in Google Scholar
Varenicline (CP 526555) is an orally active partial agonist of α4β2 nicotinic acetylcholine receptor (α4β2 nAChR, IC50 = 250 nM), which is the principal mediator of nicotine dependence. Varenicline is also a partial agonist of α6β2 nAChR and a full agonist of α7β2 nAChR. Varenicline blocks the direct agonist effects of nicotine on nAChR while stimulates nAChR in a more moderate way, being widely used as an aid of smoking cessation.

EC50: 2.3 μM (α4β2 nAChR); 18 μM (α7 nAChR); 55 μM (α3β4 nAChR)[1]
Varenicline (200 μM, 24 h) shows no affection to cell viability of HUVEC cells[3].
Varenicline (100 μM, 24 h) lowers expression of VE-cadherin in HUVEC cells as Varenicline (100 μM, 30 min) significantly activates ERK1/2 and p38 signaling[3].
Varenicline (100 μM, 4 h) promotes migration of HUVEC cells by 2.4-fold[3].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
-
Cell Line:HUVEC
-
Concentration:100, 200, 300, 500 μM
-
Incubation Time:24 h
-
Result:Did not affect cell viability at 100 and 200 μM (96.8 ± 0.1% and 93.9 ± 1.8%, respectively). Decreased cell viability to 85.7 ± 7.5% and 57.8 ± 7.7% for 300 and 500 μM, respectively.
-
Cell Line:HUVEC
-
Concentration:100 μM
-
Incubation Time:1, 5, 10, 15 ,30 ,60 min, 24 h
-
Result:Significantly activated ERK1/2 and p38 signaling with peak activity at 10–15 min and 10–30 min after treatment, respectively, lowered expression of VE-cadherin at 24 h. MLA (100 nM) significantly reversed the Varenicline-induced effects.
-
Cell Line:HUVEC
-
Concentration:100 μM
-
Incubation Time:4 h
-
Result:Significantly increased the number of migrating cells by 2.4-fold compared with vehicle treatment. MLA (100 nM) completely blocked Varenicline-stimulated migration.
Varenicline (0.004–0.04 mg/kg/h, i.v.drip, 23h a day for 7-10 d) dose-dependently reduces self-administration of nicotine alone (0.0032 mg/kg/inj), and in combination with cocaine (0.0032 mg/kg/inj) with no significant effects on food-maintained responding in cocaine- and nicotine-experienced adult rhesus monkeys[5].
Varenicline (0.178-5.6 mg/kg, i.p., acute administration) shows antidepressant-like activity in the forced swim test in C57BL/6J and CD-1 mice[6].

Select the appropriate dissolution method based on your experimental animal and administration route.
- For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
- To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
- The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.
