• 产品描述： Entacapone (OR-611) 抑制儿茶酚-O-甲基转移酶(COMT)活性，IC50为151 nM。Entacapone 是一种 FTO demethylation 的抑制剂，IC50为3.5 μM，可用于代谢紊乱的研究

• 靶点： COMT:151 nM;Transferase

• 体外研究：
  Entacapone在不同组织中抑制catechol-O-methyltransferase(COMT)的IC50值大体相似，包括肝脏，十二指肠, 肾脏和肺, 但是entacapone在这些组织中抑制效果比tolcapone更好。 Entacapone (< 100 μM)可以有效抑制α-syn和β-amyloid (Aβ) 齐聚反应和原纤维生成同时可以保护PC12细胞免受这两种蛋白聚集诱导的细胞外毒性

• 体内研究：
  Entacapone administration reduced body weight and lowered fasting blood glucose concentrations in diet-induced obese mice.

• 细胞实验： Cell lines: PC12 cells Concentrations: 5 μM Incubation Time: 72 h Method: Cells were treated with various concentrations of drug for 72 h.

• 动物实验： Animal Models: Male C57BL/6 mice Dosages: 600 mg/kg Administration: p.o.
