The present invention relates to a type of aryl benzofuran amidated derivatives, the medical use thereof, and the preparation method; said derivatives have antioxidation activity, and xanthine oxidase inhibitory activity, and can be used for antioxidation and for preparing compositions, drugs and health products and treating gout and hyperuricemia.

Compounds, and pharmaceutically acceptable salts thereof, useful as inhibitors of sodium channels are provided. Also provided are pharmaceutical compositions comprising the compounds or pharmaceutically acceptable salts and methods of using the compounds, pharmaceutically acceptable salts, and pharmaceutical compositions in the treatment of various disorders, including pain.

The present invention relates to a monascuspurpurone compound of formula (I): ##STR00001##
or a pharmaceutically acceptable derivative thereof as described in the specification, the process for preparation of the same, and the composition comprising the same. The uses of a monascuspurpurone compound for promoting adipocyte differentiation, for increasing the activity of PPAR and/or C/EBP, for lowering blood glucose, for preventing and/or treating a disease or disorder related to insulin resistance, and for preventing and/or treating metabolic syndrome or its complications are also provided.
