Compound 48/80 trihydrochloride is a mixture of condensation products of N-methyl-p-methoxyphenethylamine with formaldehyde[1].Compound 48/80 trihydrochloride is also a histamine releaser and a mast cell degranulator[2]. Compound 48/80 was first reported in 1951 as an active histamine-releasing agent[3] that can cause redness, itching, and itching of human skin [4]. Compound 48/80 was later used as a classical mast cell activator for IgE-independent G proteins and is the most commonly used activation method in pseudoallergy studies[5]. HIS secreted by mast cells induces vasodilation, edema, pruritus, and hypothermia. Compound 48/80 trihydrochloride (C48/80 trihydrochloride) inhibits both cytosolic and particulate phosphatidylinositol-specific phospholipase C activities with a similar efficiency; IC50 values are 2.1 μg/ml (supernatant) and 5.0 μg /ml (particulate fraction). The aggregation of human platelets induced by ADP and PAF-acether is inhibited by Compound 48/80[1].Compound 48/80 inhibits phosphatidylinositol-specific phospholipase C activity from human platelets[6].
In vitro，Time-course analysis of dTCTP secretion by Compound 48/80 treatment demonstrated a rapid release of dTCTP within 5 min after Compound 48/80 treatment and persistent release of dTCTP during mast cell degranulation induced by Compound 48/80[7].
In vivo，In In the analysis of systemic anaphylaxis, the body temperature of the model group (Compound 48/80) was significantly lower than that of the control group. Compound 48/80 induced increased serum concentrations of HIS, TNF-α and IL-8[8]. Compound 48/80-induced MC degranulation produced anticonvulsive effects against PTZ-induced epileptic seizures by extending the onset time of both myoclonic-jerk and generalized tonic–clonic seizure, and by shortening the duration of generalized tonic–clonic seizure[9].
