用途: Catharanthine inhibits nicotinic receptor mediated diaphragm contractions with IC50 of 59.6 μM.Target: nAChRCatharanthine evokes a concentration-dependent attenuation of carbachol responses in the rat ileum preparation, producing rightward curve displacements and decreases in maximal agonist responses. The mixture of serpentine, plus ajmalicine and catharanthine reveals a concentration-dependent inhibitory effect of acethylcholinesterase (AchE), with an IC50 at ca. 2.25 μg/Ml [1]. Catharanthine can induce the self-association of tubulin into linear indefinite polymers with an efficacy that is 75% that of vinblastine or vincristine. Catharanthine binds to tubulin alpha-beta dimer with binding constant of 2.8 mM [2]. Catharanthine stimulates release of amylase from pancreatic fragments and to cause extensive degranulation of pancreatic acinar cells with accumulation of membrane material in the Golgi region. Catharanthine induces a delayed release of Ca2+ from prelabeled pancreatic fragments as compared to bethanechol [3]. Catharanthine inhibits epibatidine-induced Ca(2+) influx in TE671-α, -β, -γ, -δ cells in a noncompetitive manner with similar potencies IC50 of 17 mM-25 mM. Catharanthine inhibits [3H]TCP binding to the desensitized Torpedo AChR with higher affinity compared to the resting AChR. Catharanthine enhances [3H]cytisine binding to resting but activatable Torpedo AChRs, suggesting desensitizing properties [4]. 物理化学性质: CAS号:2468-21-5 常用中文名:长春质碱 常用英文名:Catharanthine 分子式:C21H24N2O2 分子量:336.427 密度:1.3±0.1 g/cm3 沸点:491.5±45.0 °C at 760 mmHg 熔点:138-140ºC 闪点:251.1±28.7 °C 储存条件:库房低温通风干燥 |
