CALMIDAZOLIUM CHLORIDE

Compound 48/80 (Poly-p-methoxyphenethylmethylamine) is widely used in animal and tissue models as a "selective" mast cell activator. Compound 48/80 acts at the mast cell membrane to stimulate trimeric G-proteins and induces degranulation via phospholipase C and D pathways[1][2].
