Escin Ib

Escin Ib is a triterpene saponin that has been found in A. hippocastanum and has diverse biological activities. It inhibits HIV-1 protease (IC50 = 50 µM). Escin Ib (50-200 mg/kg) inhibits carrageenan-induced paw edema in rats and scratching behavior induced by compound 48/80 (Cay-22173) in mice. It inhibits ethanol absorption and increases glucose tolerance in rats. Escin 1b (10-50 mg/kg) also decreases mucosal lesion size and severity in a rat model of ethanol-induced gastric ulcers.Formal Name: (3beta,4beta,16alpha,21beta,22alpha)-22-(acetyloxy)-16,23,28-trihydroxy-21-[[(2Z)-2-methyl-1-oxo-2-buten-1-yl]oxy]olean-12-en-3-yl O-beta-D-glucopyranosyl-(1->2)-O-[beta-D-glucopyranosyl-(1->4)]-beta-D-glucopyranosiduronic acid.
