Compound 48/80, powder

Compound 48/80 used to induce degranulation of GnRH-like immunoreactivity of mast cells in the brain and mesentery and for elucidating the mechanism by which anti-allergic medications suppress conjunctivitis.
Potent histamine releasing agent, primarily from mast cells, with a subsequent depletion of tissue histamine. It is the action of mast cell mediators on the cardiovascular system that leads to circulatory collapse. The toxicity is due to more than histamine release. It is a potent inhibitor of phospholipase C. Activates G proteins by a mechanism analogous to that of mastorparan. Inhibits calmodulin and human platelet PLC and exhibits a concentration dependent biphasic modulation of human platelet PLA2.
Soluble in water (100 mg/mL-clear solution.)
