Novel thiazole derivatives as inhibitors of superoxide production by human neutrophils: Synthesis and structure-activity relationships

Article abstract of DOI:10.1021/jm00002a017

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.
