Genipin ((+)-Genipin) 是衍生自Gardenia jasminoidesEllis 果实的天然交联剂。Genipin 抑制细胞中的 UCP2 (解偶联蛋白 2)。Genipin 具有多种生物活性,包括蛋白质调节,抗肿瘤,抗炎症,免疫抑制,抗血栓形成和对海马神经元的保护。Genipin 也可用于 2 型糖尿病研究。
生物活性 | Genipin ((+)-Genipin) is a natural crosslinking reagent derived fromGardenia jasminoidesEllisfruits. Genipin inhibits UCP2 (uncoupling protein 2) in cells. Genipin has a variety of bioactivities, including modulation on proteins, antitumor, anti-inflammation, immunosuppression, antithrombosis, and protection of hippocampal neurons. Genipin also can be used for type 2 diabetes research[1][2]. |
体外研究 (In Vitro) | Genipin increases mitochondrial membrane potential, increased ATP levels, closed KATP channels, and stimulated insulin secretion in pancreatic islet cells. Genipin causes suppression of insulin signal transduction through hyperactivation of c-Jun N-terminal kinase (JNK) and subsequent serine phosphorylation of insulin receptor substrate-1 (IRS-1), thus impairing insulin-stimulated glucose uptake in 3T3-L1 adipocytes[1]. Genipin activates IRS-1, PI3-K, and downstream signaling pathway and increases concentrations of calcium, resulting in glucose transporter 4 (GLUT4) translocation and glucose uptake increase in C2C12 myotubes[1]. Cytochrome c content increases significantly in the cytosol of Genipin-treated FaO cells. Activation of caspase-3 and caspase-7 is ultimately responsible for Genipin-induced apoptotic process in hepatoma cells. ROS level notably increases in Hep3B cells treated with 200 μM Genipin[2].
