KHK-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[1].
