Product Introduction
Bioactivity
英文名: Varenicline Tartrate
描述: Varenicline Tartrate (CP 526555-18) 是α4β2 烟碱乙酰胆碱受体的部分激动剂,EC50为 2.3 μM。它是 α3β4 和 α7 乙酰胆碱受体完全激动剂,EC50值分别为 55 和 18 μM,用于戒烟方面的研究。
激酶实验: Kinase inhibition: Vandetanib is incubated with enzyme, 10 mM MnCl2, and 2 μM ATP in 96-well plates coated with a poly(Glu, Ala, Tyr) 6:3:1 random copolymer substrate. Phosphorylated tyrosine is then detected by sequential incubation with a mouse IgG anti-phosphotyrosine 4 g10 antibody, a horseradish peroxidase-linked sheep antimouse immunoglobulin antibody, and 2,2′-azino-bis(3-ethylbenzthiazoline-6-sulfonic acid). This methodology is adapted to examine selectivity versus tyrosine kinases associated with EGFR, PDGFRβ, Tie-2, FGFR1, c-kit, erbB2, IGF-1R, and FAK. All enzyme assays (tyrosine or serine-threonine) used appropriate ATP concentrations at or just below the respective Km (0.2–14 μM). Selectivity versus serine-threonine kinases (CDK2, AKT, and PDK1) is examined using a relevant scintillation proximity-assay (SPA) in 96-well plates. CDK2 assays contained 10 mM MnCl2, 4.5 μM ATP, 0.15 μCi of [γ-33 P]ATP/reaction, 50 mM HEPES (pH 7.5), 1 mM DTT, 0.1 mM sodium orthovanadate, 0.1 mM sodium fluoride, 10 mM sodium glycerophosphate, 1 mg/mL BSA fraction V, and a retinoblastoma substrate (part of the retinoblastoma gene, 792–928, expressed in a glutathione S-transferase expression system; 0.22 μM final concentration). Reactions are allowed to proceed at room temperature for 60 minutes before quenching for 2 hours with 150 μL of a solution containing EDTA (62 mM final concentration), 3 μg of a rabbit immunoglobulin anti-glutathione S-transferase antibody and protein A SPA-polyvinyltoluene beads (0.8 mg/reaction). Plates are then sealed, centrifuged (1200× g for 5 minutes), and counted on a Microplate scintillation counter for 30 seconds.
体外活性: Varenicline is a partial agonist with 45% of nicotine's maximal efficacy atalpha4beta2 nAChRs in HEK cells expressing nAChRs. [1] Varenicline is a potent, partial agonist at alpha4beta2 receptors, with an EC50 of 2.3 mM and an efficacy (relative to acetylcholine) of 13.4%. Varenicline has lower potency and higher efficacy at alpha3beta4 receptors, with an EC50 of 55 mM and an efficacy of 75%. [2]
体内活性: Varenicline has significantly lower (40-60%) efficacy than nicotine in stimulating [(3)H]-dopamine release from rat brain slices in vitro and in increasing dopamine release from rat nucleus accumbens in vivo, while it is more potent than Nicotine. Varenicline effectively attenuates the nicotine-induced dopamine release to the level of the effect of Varenicline alone, consistent with partial agonism. Varenicline reduces nicotine self-administration in rats and supports lower self-administration break points than nicotine. [1] Varenicline dose-dependently reduces nicotine self-administration and attenuates both nicotine prime and combined nicotine prime plus nicotine-paired cue-induced reinstatement. [3] Varenicline, a partial agonist at thealpha4beta2 nAChRs, reduces nicotine intake and was recently approved as a smoking cessation aid. Varenicline selectively reduces ethanol but not sucrose seeking using an operant self-administration drinking paradigm and also decreases voluntary ethanol but not water consumption in animals chronically exposed to ethanol for 2 months before Varenicline treatment.
