Drug compound for treating hepatopathy and application thereof
-
Paragraph 0364-0366, (2019/10/15)
The invention discloses a drug compound for treating hepatopathy and application thereof. The drug compound specifically serves as a compound shown in general formula (I) or an optical isomer or a pharmaceutically-acceptable salt of the compound. The compound or the optical isomer or the pharmaceutically-acceptable salt of the compound has a good curative effect and low toxicity on hepatopathy, especially fatty liver. Experiments show that the compound has an obvious protective effect on zebrafish nonalcoholic fatty liver, so that the drug compound has a good application prospect in medicinesfor treatment or prevention of hepatopathy, especially fatty liver or liver fibrosis or liver cirrhosis.

A systematic investigation of the human metabolism of hydroxycinnamic acid conjugates was carried out. A set of 24 potential human metabolites of coffee polyphenols has been chemically prepared, and used as analytical standards for unequivocal identifications. These included glucuronide conjugates and sulfate esters of caffeic, ferulic, isoferulic, m-coumaric and p-coumaric acids as well as their dihydro derivatives. A particular focus has been made on caffeic and 3,4-dihydroxyphenylpropionic acid derivatives, especially the sulfate conjugates, for which regioselective preparation was particularly challenging, and have so far never been identified as human metabolites. Ten out of the 24 synthesized conjugates have been identified in human plasma and/or urine after coffee consumption. A number of these conjugates were synthesized, characterized and detected as hydroxycinnamic acid metabolites for the first time. This was the case of dihydroisoferulic acid 3′-O-glucuronide, caffeic acid 3′-sulfate, as well as the sulfate and glucuronide derivatives of 3,4-dihydroxyphenylpropionic acid.
