Novel Chlorogenic Acid Derivatives and Composition for Treating Inflammatory Disease Comprising the Same
-
Paragraph 0144-0146, (2021/05/22)
The present invention relates to a novel chlorogenic acid derivative compound having anti-inflammatory activities and to an anti-inflammatory composition including the same as an active ingredient. The chlorogenic acid derivative compound of the present invention controls the overproduction of nitrogen oxide (NO) derived by the treatment of LPS in histiocytes. The chlorogenic acid derivative compound of the present invention inhibits the activation of NF-κB which is an important signal transmittal intermediated transcription factor in oxidant stress and inflammation promoting routes. The chlorogenic acid derivative compound of the present invention has a high possibility of being developed into an agent for treating various inflammatory diseases by inhibiting the overproduction of NO and the activation of NF-κB.

A one-step conversion of alcohols into thioesters under solvent-free conditions is reported. The alcohols were reacted with primary thioamides in the presence of p-toluenesulfonic acid under solvent-free conditions to produce the corresponding thioesters in good to excellent yields.

Neutrophils have an important role in the self-defense systems of organisms through the production of superoxide. On the other hand, it has been proposed that abnormal amounts of superoxide produced by neutrophils are a serious factor in tissue injury. A series of novel thiazole derivatives was prepared and evaluated inhibitory effect on superoxide production by human neutrophils in vitro. Among these compounds, 6-[2-(3,4- diethoxyphenyl)thiazol-4-yl]-pyridine-2-carboxylic acid (OPC-6535) was selected as one of the most promising compounds. The synthesis and structure- activity relationships of these compounds are reported herein.

The reaction of haloketones, obtained from Arndt-Eistert reaction on the acid chlorides of 1-adamantane, 5-nitrofuroic acid and pyrazine-2-carboxylic acid, with different thioamides and thioureas affords the title thiazoles (I-III).Some of them exhibit interesting antitubercular activity at 6.25 to 0.38 μg/ml concentration against H37Rv strain of M. tubercolosis in vitro testing.The structure activity relationship (SAR) has also been discussed.
ELECTRON DEFICIENT HETEROAROMATIC AMMONIOAMIDATES, XVIII. THE SYNTHESIS AND PHOTOCHEMISTRY OF SOME N-ISOQUINOLINO(THIOAMIDATES)

Thioacylation of isoquinolinioamide furnished the N-isoquinolinio(thioamidates) 2a-2c.Depending on the solvent, 2c exists either as a mixture with its tricyclic tautomer 5, or exclusively as the latter.The NMR and mass spectra, and the photochemistry of compounds 2a-2c are discussed.The photoproducts obtained include 3,4-dimethoxybenzonitrile, 3,4-dimethoxy(thiobenzamide), O-ethyl thiocarbamate, 1(2H)-isoquinolinethione (7a), 1(2H)-isoquinolinone (7b) and thiadiazoloisoquinolin-4-ium-2-olate (8a).Differences between the fragmentation upon electron impact and the photochemistry of the thioamidates of Types 1 and 2, as well as between the photochemistry of the thioamidates 2 and their amidate counterparts of Type 3 are discussed.Potassium permanganate oxidation of thiadiazoloisoquinolin-4-ium-2-thiolate (8b) furnishes the olate 8a and 1-isoquinolyl thiocyanate (12).
