Non-alcoholic fatty liver disease (NAFLD) is becoming the most predominant burden of chronic liver disease worldwide. Non-alcoholic steatohepatitis (NASH), the progressive form of NAFLD, can develop into cirrhosis and hepatocellular cancer. Unfortunately, current options for therapeutic treatment of NASH are very limited. Among multiple pathways in NASH, farnesoid X receptor (FXR), a nuclear bile acid receptor, is well-recognized as an important effective target. Here we report the synthesis and characterization of compound HEC96719 a novel tricyclic FXR agonist based on a prior high-affinity nonsteroidal molecule GW4064. HEC96719 exhibits excellent potency superior to GW4064 and obeticholic acid in in vitro and in vivo assays of FXR activation. It also shows higher FXR selectivity and more favorable tissue distribution dominantly in liver and intestine. Preclinical data on pharmacokinetic properties, efficacy, and safety profiles overall indicate that HEC96719 is a promising drug candidate for NASH treatment.

The invention discloses a preparation method of an intermediate for synthesizing huperzine A. The preparation method comprises the following steps: substituting 3-bromine-6-methoxy-2-methyl pyridine taken as a raw material with N-bromosuccinimide so as to obtain a substitution product; carrying out a reaction on the substitution product and methyl acetoacetate and then carrying out ring closing reaction under the action of cuprous iodide so as to obtain 2-methoxy-6-hydroxy-7,8-dihydro-5-quinoline carboxylic methyl ester. According to the method provided by the invention, the synthesis reaction cost is low, so that the production cost is effectively lowered; the reaction conditions are moderate, so that the safety of operating personnel is ensured; a refining process is convenient and simple to operate; the intermediate obtained via the reaction is good in quality, high in yield and good in environmental friendliness.
