Muscarine tosylate  (Synonyms: (+)-Muscarine tosylate)

Muscarine ((+)-Muscarine) tosylate is an agonist of prototype mAChR. Muscarine tosylate is a toxin that can stimulate the parasympathetic nervous system^[1][2].

Muscarine tosylate (100 µM) induces an intracellular calcium signal amplitude similar to the one triggered by 10 µM acetylcholine in brain miero vascular endothelial cells (BMVECs) and brain-derived Endothelial cells.3 (bEnd.3)^[1].
Muscarine tosylate (1-30 μM; 2 min) produces a dose-dependent hyperpolarization in a sub-population of the nucleus raphe magnus (NRM) cells that contain 5-hydroxytryptamine (5-HT) on the NRM neurons with an EC₅₀ value of 2.7 µM^[2].
