摘要： Ethnopharmacological relevance: Koumine, an indole alkaloid extracted from Gelsemium elegans Benth, exerts anti-inflammation and antioxidant activities. However, the effects of koumine on intestinal injury induced by H2O2 and its potential molecular mechanisms need larger studies. Aim of the study: We established an IPEC-J2 cell damage model induced by H2O2 to explore the protective mechanism of koumine on intestinal injury.Materials and methods: In the experiment, cell damage models were made with hydrogen peroxide. To assess the protective effect of koumine on H2O2-induced IPEC-J2 cell injury, CCK-8, the release of LDH and ROS, trans-mission electron microscopy and Annexin V-FITC/PI were employed. Western Blot and Quantitative Real-time PCR were used to determine the potential alleviated mechanism of koumine on H2O2-trigged IPEC-J2 cell damage.Results: The results of CCK-8 and LDH implied that koumine has a mitigative effect on H2O2-induced cell damage via upregulating cell viability and suppressing cell membrane fragmentation. Simultaneously, koumine notably inhibited the level of pro-inflammatory factors (IL-1 beta, IL-6, IL-8, TNF-alpha and TGF-beta), the over-production of ROS along with decreasing the injury of mitochondrion, endoplasmic reticulum and lysosome induced by H2O2. Moreover, koumine dramatically attenuated H2O2-triggered IPEC-J2 cell apoptosis and autophagy. Subse-quently, Western blot analysis identified NF-Kappa B, PI3K and ERS as possible pathway responsible for the protective effect of koumine on H2O2-stimulated IPEC-J2 cell inflammation.
