ATP-citrate lyase (ACLY) converts cytosolic citrate from the tricarboxylic acid cycle (TCA cycle) into acetyl coenzyme A (acetyl-CoA), which is a building block for cholesterol and fatty acid synthesis. Abnormally high expression of ACLY is associated with multiple metabolic diseases including dyslipidemia, atherosclerosis and non-alcoholic steatohepatitis (NASH), making ACLY an appealing target. In previous work, we discovered 326E, featuring an alkenyl dicarboxylic acid scaffold as a novel ACLY inhibitor. 326E can be potentially used to treat hypercholesterolemia and is currently undergoing phase II clinical trials. In this study, we have developed a series of diacids containing conjugated diene based on impurities in manufacturing process of 326E in GMP condition, which represented a unique structural type different from known ACLY inhibitors. Among synthesized all eight possible isomers, compound 43ZZ and 52EE exhibited significant inhibitory effect on de novo lipogenesis and gluconeogenesis in vitro and 43ZZ showed favorable pharmacokinetics. Furthermore, oral administration of 43ZZ and 52EE demonstrated a marked reduction of hepatic lipogenesis, along with lowered plasma levels of triglyceride and cholesterol, thereby confirming that these diene diacids as novel ACLY inhibitors have therapeutic potential for hyperlipidemia.
