Description
Catalpol is an iridoid glycoside that has been isolated from
R. glutinosa and has diverse biological activities, including anti-apoptotic, pro-angiogenic, and radioprotective properties. It protects against mitochondrial pathway-dependent apoptosis in PC12 rat adrenal pheochromocytoma cells and H9c2 rat embryonic ventricular myocardial cells when used at a concentration of 10 μM. Catalpol pretreatment reduces apoptosis and improves viability in AHH-1 human lymphocyte cells exposed to ionizing radiation and reduces intestinal damage induced by radiation in mice when used at concentrations and doses ranging from of 25 to 100 μg/ml and 25 to 100 mg/kg, respectively. In a rat model of stroke, catalpol (5 mg/kg, i.p.) increases the expression of erythropoietin and VEGF and improves angiogenesis in the brain.
in vivo
Catalpol (25-100mg/kg; intraperitoneal injection; once) treatment clearly reduces blood urea nitrogen, serum creatinine levels and the expression of KIM-1 in renal ischemia/reperfusion-injury (IRI) mice. Catalpol markedly reduces the expression of PI3K, Akt and eNOS levels, and suppresses the TNF-α, IL-1β, IL-6 and IL-10 activities[1].
