Ketohexokinase
KHK
Ketohexokinase (KHK), a member of the ribokinase superfamily of kinases, catalyzes the conversion of fructose to fructose-1-phosphate in an ATP- and K+- dependent manner. This reaction is the rate-limiting first step in the fructose metabolic pathway. The Ketohexokinase gene gives rise to two isoforms, KHK-A and KHK-C, through alternative splicing. KHK-C, mainly expressed in the liver and small intestine, is responsible for the majority of fructose metabolism in these tissues, playing a key role in normal fructose-induced lipogenesis and other metabolic processes. In contrast, KHK-A, ubiquitously expressed in most tissues, has a relatively low enzymatic activity for fructose phosphorylation under physiological conditions. Dysregulation of Ketohexokinase activity, especially over-activation in the context of high fructose intake, is closely associated with a variety of metabolic disorders, including obesity, diabetes, non-alcoholic fatty liver disease (NAFLD), and non-alcoholic steatohepatitis (NASH) [1][2][3].

LY3522348
0 ImagesSynonyms: KHK-IN-3KHK-IN-3 (Example 1) is a ketohexokinase (KHK) inhibitor. KHK-IN-3 can be used in the study of kidney disease, nonalcoholic steatohepatitis (NASH), diabetes and heart failure. KHK is a rate-limiting enzyme and fructokinase involved in fructose metabolism. KHK catalyzes the phosphorylation of fructose to fructose-1-phosphate (FIP) at the expense of ATP. The lack of feedback inhibition of fructose metabolism triggers the accumulation of downstream intermediates such as lipogenesis, gluconeogenesis, and oxidative phosphorylation.
