Abstract: The present invention provides a 2-pyridone derivative having a structure represented by formula I, or a stereoisomer or pharmaceutically acceptable salt thereof. Activity experiment results show that the 2-pyridone derivative provided in the present invention has higher activity and selectivity, and can be used to treat thyroid hormone receptor-related diseases.

Abstract: The present invention provides a 1,2,4-triazine-3,5-dione compound, a preparation method therefor, and an application thereof. The 1,2,4-triazine-3,5-dione compound having a structure represented by formula (I) provided by present invention has a selective agonistic effect on THR?, and the activity, selectivity, and metabolic stability thereof have significant advantages over disclosed compounds, and can function as a therapeutic and/or preventive drug for thyroid hormone receptor related diseases, comprising, but not limited to, obesity, diabetes, hypercholesterolemia, hyperlipidemia, hypertriglyceridemia, liver steatosis, non-alcoholic fatty liver disease, nonalcoholic steatohepatitis, familial hypercholesterolemia, dyslipidemia, atherosclerosis, hypothyroidism, and thyroid cancer.

Abstract: The present invention relates to an alkyne derivative, a preparation method for same, and applications thereof in medicine. Specifically, the present invention relates to the alkyne derivative as represented by formula (I), the preparation method for same, a pharmaceutically acceptable salt thereof, and uses of them as a therapeutic agent, specifically as a phosphoinositide 3-kinase ? (PI3K?) inhibitor, where the definitions of the substituents in formula (I) are identical to the definitions in the description.

Abstract: The present invention relates to a cyano-substituted heteroarylpyrimidinone derivative represented by formula (I), a preparation method therefor and a use thereof as a therapeutic agent, in particular a use as an acetyl-CoA carboxylase (ACC) inhibitor, and the definition of each substituent in formula (I) is the same as the definition in the description.
