KHK-IN-2

KHK-IN-2 is a highly potent and selective inhibitor of fructokinase (KHK) with an IC₅₀ of 0.45μM^[1]. KHK catalyzes the first step in fructose metabolism, and in animal models, KHK inhibition reduces hepatic de novo lipogenesis and steatosis and corrects many metabolic abnormalities associated with insulin resistance^[2]. KHK-IN-2 can be used to study fructose metabolism-related diseases such as non-alcoholic fatty liver disease (NAFLD), diabetes, and obesity^{[3, 4]}.

KHK-IN-2是一种高效，选择性的果糖激酶（KHK）抑制剂，IC₅₀为0.45μM^[1]。KHK催化果糖代谢的第一步，在动物模型中，KHK抑制可减少肝脏新生脂肪生成和脂肪变性，并纠正与胰岛素抵抗相关的许多代谢异常^[2]。KHK-IN-2能够用于研究果糖代谢相关疾病，如非酒精性脂肪肝病（NAFLD）、糖尿病和肥胖症^{[3, 4]}。
