Optically pure (+)-nicotine from (+/-)-nicotine and biological comparisons with (-)-nicotine
Abstract:
Optically pure (+)-nicotine has been obtained from (+/-)-nicotine using a combination of d-tartaric acid and di-p-toluoyl-l-tartaric acid. As the di-d-tartrate salt, (+)-nicotine is less potent than (-)-nicotine di-l-tartrate in producing lethality in mice, on blood pressure in anesthetized rats, and in the isolated guinea-pig ileum, indicating substantial stereospecificity for nicotine receptors. Potency ratios are 0.14, 0.06, and 0.019, respectively.

Cholinergic Receptors: Nicotinic
There are two types of nicotinic receptors: neuromuscular (NM/NM/N1) and neuronal (NN/NN/N2). The two families differ based on their location and selectivity to...
Drugs Acting on Autonomic Ganglia: Stimulants
Ganglionic stimulants activate NM nicotinic receptors in autonomic ganglia, falling into two categories: nicotine mimetics [e.g., lobeline, dimethylpiperazine, tetramethylammonium] and muscarinic receptor agonists [e.g., muscarine, methacholine]. The first category's action is rapid and blocked by nicotinic receptor antagonists, while the second category's action is delayed and blocked by atropine-like agents. Nicotine, an alkaloid, affects the heart rate by stimulating sympathetic or...
