Varenicline Hydrochloride
Based on 1 Customer Validation
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 α6β2 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.

Biological Activity
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].

-
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].

-
Animal Model:Eighty male Wistar rats (250-300 g)[1]
-
Dosage:0.5 mg/kg/day, 1 mg/kg/day or 2 mg/kg/day
-
Administration:Subcutaneous injection; twice daily; for 14 days
-
Result:Significantly higher DRD2/3 availability in the ventral striatum of approximately 11%, while only the rats treated with 1 and 2 mg/kg/day dose showed significantly higher DRD2/3 availability in the dorsal striatum by 12.5% and 13.2%, respectively.
