Varenicline dihydrochloride  (Synonyms: CP 526555 dihydrochloride)

Cat. No.: HY-10019A Purity: 99.21%
COA Handling Instructions

Varenicline (CP 526555-18) 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.

Description

Varenicline (CP 526555-18) 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[1][2][3][4][5].

IC50 & Target

EC50: 2.3 μM (α4β2 nAChR); 18 μM (α7 nAChR); 55 μM (α3β4 nAChR)[2]

In Vitro

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 Viability Assay[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.

Western Blot Analysis[3]

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 Migration Assay [3]

Cell Line: HUVEC
Concentration: 100, 200, 300, 500 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.
In Vivo

Varenicline (0.5, 1mg/kg, s.c., acute administration) dose-dependently reverses Fentanyl-induced respiratory depression in rats while slightly alleviates Fentanyl-induced sedation[4].
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].

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
