生物信息
产品描述 Esculetin is an active ingredient extracted mainly from the bark of Fraxinus rhynchophylla. Esculetin inhibits platelet-derived growth factor (PDGF)-induced airway smooth muscle cells (ASMCs) phenotype switching through inhibition of PI3K/Akt pathway. Esculetin has antioxidant, antiinflammatory, and antitumor activities.
信号通路 PI3K/Akt; Cell cycle; Apoptosis
靶点 Caspase-3 Caspase-9 - - -
IC50 - - - - -
体外研究 Esculetin decreases cell proliferation by inducing G1 phase cell cycle arrest, which is associated with the down-regulation of cyclin D1/CDK4 and cyclin E/CDK2 complexes by the activation of p27KIP. Esculetin significantly inhibits proliferation of HCC cells in a concentration- and time-dependent manner and with an IC50 value of 2.24 mM. It blocks the cell cycle at S phase and induces apoptosis in SMMC-7721 cells with significant elevation of caspase-3 and caspase-9 activity, but does not affect caspase-8 activity. Esculetin treatment results in the collapse of mitochondrial membrane potential in vitro and in vivo accompanied by increased Bax expression and decreased Bcl-2 expression at both transcriptional and translational levels. Esculetin exerts in vitro and in vivo antiproliferative activity in hepatocellular carcinoma, and its mechanisms involved initiation of a mitochondrial-mediated, caspase-dependent apoptosis pathway.
体内研究 Esculetin significantly decreases tumor growth in mice bearing Hepa1-6 cells. Tumor weight is decreased by 20.33, 40.37, and 55.42% with increasing doses of esculetin. Of note, esculetin has no obvious toxicity in this animal study. In a rat experimental model of inflammatory bowel disease induced by trinitrobenzenesulfonic acid, esculetin at the dose of 5 mg/kg displays intestinal anti-inflammatory activity.
