- Novel compound and composition for prevention, improvement or treatment of fibrosis or non-alcoholic steatohepatitis comprising the same
-
The present invention relates to a novel compound and a composition for prevention, improvement, or treatment of fibrosis or nonalcoholic steatohepatitis comprising the same as an active ingredient. More specifically, the present invention relates to a novel compound of chemical formula 1 which has an excellent effect for prevention, improvement, or treatment of fibrosis and a composition for prevention, improvement, or treatment of fibrosis or nonalcoholic steatohepatitis comprising the same as an active ingredient. A novel compound of the present invention effectively controls expression of snail and vimentin which are a controlling element of Epithelial Mesenchymal Transition (EMT) and controls activation of EMT, and thus effectively prevents, improves, or treats fibrosis accordingly. Additionally, a novel compound of the present invention has a very excellent pharmacokinetic characteristic, and thus can perform fast drug delivery to the body through oral administration, stably displays an effect in the body, and is secure to use without a big side effect. Moreover, since a novel compound of the present invention can effectively block fibrosis of a hepatic cell, nonalcoholic steatohepatitis can effectively improved or treated.(AA) Chemical formula 1COPYRIGHT KIPO 2018

- USE OF CHROMONE DERIVATIVE AS PHARMACEUTICAL COMPOSITION FOR PREVENTION AND TREATMENT OF FIBROSIS USING EMT INHIBITORY ACTIVITY
-
A pharmaceutical composition contains the chromone derivative of Chemical Formula 1 and a pharmaceutically acceptable salt as an active ingredient, thus effectively inhibiting the activation of EMT to thereby enable the effective suppression of a disease caused by fibrosis of an organ or tissue in vivo due to the activation of EMT.

- 5, 7-dihydroxy-6-production of polymethoxyflavones
-
PROBLEM TO BE SOLVED: To provide an efficient production method of 5,7-dihydroxy-6-methoxyflavones in a short step. SOLUTION: The production method of 5,7-dihydroxy-6-methoxyflavones includes a step of demethylating 5,6,7-trimethoxy-8-acylflavones expressed by general formula (II). In the formula, n represents an integer of 0 to 5; R2represents a hydroxyl group or the like and when n is 2 or more, a plurality of R2may be the same or different from each other; and R3represents a 1-4C straight-chain or branched alkyl group or the like.
