Pharmacological properties of Y-19,432. I. Anti-allergic effect

Anti-allergic properties of curine, a bisbenzylisoquinoline alkaloid.

Curine is a bisbenzylisoquinoline alkaloid isolated from Chondrodendron platyphyllum (Menispermaceae). Recent findings have shed light on the actions of curine in different models of allergy and inflammation. Here we review the properties and mechanisms of action of curine focusing on its anti-allergic effects. Curine pre-treatment significantly inhibited the scratching behavior, paw edema and ...

Isolation and Characterisation of Anti-diabetic Pharmacological Activities of Phytoestrogens

Anti-allergic effect of Fructus cnidii ethanol extracts

This study was mainly to observe the anti-allergic effect of Fructus cnidii ethanol extract. Three methods were chose to observe the anti-allergic effect of Fructus cnidii including rat Passive Cutaneous Anaphylaxis (PCA) tests, rat skull periosteum mast cell degranulation tests, and histamine released factors in rat peritoneal mast cells sensitized mast cells with vitro techniques. The PCA inh...

Pharmacological study of anti-allergic activity of Syzygium cumini (L.) Skeels.

Myrtaceae is a plant family widely used in folk medicine and Syzygium and Eugenia are among the most important genera. We investigated the anti-allergic properties of an aqueous leaf extract of Syzygium cumini (L.) Skeels (SC). HPLC analysis revealed that hydrolyzable tannins and flavonoids are the major components of the extract. Oral administration of SC (25-100 mg/kg) in Swiss mice (20-25 g;...

Pharmacological activities of glycyrrhetinic acid derivatives: analgesic and anti-type IV allergic effects.

Glycyrrhetinic acid (Ia) and fourteen derivatives of glycyrrhetinic acid were examined to estimate the antinociceptive activity (tests on writhing and vascular permeability induced by 0.7% acetic acid) and anti-type IV allergic effects in mice. Among them, three dihemiphthalate compounds (IIf, IIIc, IVc) derived from, deoxoglycyrrhetol (IIa), showed strong inhibition of writhing and dye leakage...
