The present invention relates to biaryl derivatives of Formula 1, a method for preparing the same, a pharmaceutical composition comprising the same and use thereof. The biaryl derivatives of Formula 1 according to the present invention promote GLP-1 formation in the gastrointestinal tract and improve insulin resistance in the liver or in muscle due to anti-inflammatory action in macrophages, lipocytes, etc., and can accordingly be effectively used for preventing or treating diabetes, complications of diabetes, obesity, non-alcoholic fatty liver, steatohepatitis, osteoporosis or inflammation.

The anticonvulsant effect of a series of 6-alkoxy-N,N-disubstituted-2-pyridinamines is described. An investigation was carried out to optimize the activity/side-effect ratio in this series of compounds. The most desirable profile was seen with 1-[6-(2-methylpropoxy)-2-pyridinyl]piperazine, 6, and this compound was selected for a more complete pharmacological evaluation. Overall, 6 has a pharmacological
