title: In vitro studies of some 2,4-disubstituted thiazolyl-aminoketones with anti-inflammatory activity. Correlation with lipophilicity and structural characteristics.
abstract: A number of ring and chain substituted aminothiazole derivatives with strong anti-inflammatory activity were studied for their antiproteolytic and oxygen radical scavenging properties. Their interactions with the stable free radical 1,1-diphenyl-2-picrylhydrazyl was determined. Their inhibition of the soybean 12-lipoxygenase and beta-glucuronidase enzymes was evaluated. They scavenged superoxide anion and inhibited proteolysis to a non appreciable extent, whereas no activity on beta-glucuronidase and lipoxygenase was found. Their reducing ability was found to be low. Good correlation was obtained between the anti-inflammatory activity and clog P (theoretically calculated lipophilicity) and between anti-inflammatory activity and proteolytic inhibition. RM values were also determined.
