| Bioactivity | Lobeline (α-Lobeline; L-Lobeline), a lipophilic alkaloidal, is a nicotinic receptor agonist. Lobeline inhibits d-methamphetamine self-administration with no dopaminergic toxicity. Lobeline rescues d-amphetamine abuse induced addictive effect. Lobeline increases dopamine (DA) release by inhibiting DA uptake into synaptic vesicles, and altering presynaptic DA storage[1][2][3]. |
| Invitro | Lobeline (0.1-100 μM) 诱导 [3H]DA 溢出呈非钙依赖性[1]。Lobeline 抑制 [3H]DA 被突触小体 (IC50=80 μM) 和囊泡 (IC50=0.88 μM) 摄取[1]。Lobeline (0.1-1μM; 1 h) 抑制 1 μM d-methamphetamine 诱导的纹状体切片释放多巴胺[2]。 |
| In Vivo | Lobeline (0.3-3.0 mg/kg; 皮下注射; 单剂量) 降低模型大鼠 d-methamphetamine 的自我给药能力[3]。Lobeline (3 mg/kg; 皮下注射; 7 个周期，共 7 次) 以非竞争性的方式特别降低大鼠对 d-methamphetamine 的反应，并增加耐受性发展[3]。 Animal Model: |
