生物活性

Escin IIb, isolated from horse chestnut, the seeds of Aesculus hippocastanum L., has positive effects on acute inflammation in animals[1]. Escin IIb showed potent protective effects against ethanol-induced gastric mucosal lesions[2].

体内研究
(In Vivo)

Escins Ia, Ib, IIa, and IIb (50-200 mg/kg) inhibit the increase of vascular permeability induced by both acetic acid in mice and histamine in rats. Escins Ib, IIa, and IIb (50-200 mg/kg) also inhibit that induced by serotonin in rats, but escin Ia didn’t. Escins Ia, Ib, IIa, and IIb (200 mg/kg) inhibit the hind paw edema induced by carrageenin at the first phase in rats. Escin Ia (200 mg/kg) and escins Ib, IIa, and IIb (50-200 mg/kg) inhibit the scratching behavior induced by compound 48/80 in mice, but escin Ia was weakest[1].
Escin IIb (10-50 mg/kg; p.o.) potently inhibits ethanol-induced gastric mucosal lesions[2].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Model: Male Sprague–Dawley rats (Ethanol-induced gastric mucosal lesions in rats)[2]
Dosage: P.o.
Administration: 10-50 mg/kg
Result: Showed a potent protective effect against ethanol-induced gastric lesions in rats.

生物活性

Cucurbitacin IIb is an active component isolated from Hemsleya amabilis, induces apoptosis with anti-inflammatory activity. Cucurbitacin IIb inhibits phosphorylation of STAT3, JNK and Erk1/2, enhances the phosphorylation of IκB and NF-κB (p65), blocks nuclear translocation of NF-κB (p65) and decreases mRNA levels of IκBα and TNF-α[1].
