A novel orally active inhibitor of IL-1 generation: synthesis and structure-activity relationships of 3-(4-hydroxy-1-naphthalenyl)-2-propenoic acid derivatives
A new series of 3-(4-hydroxy-l-naphthalenyl)-2-propenoic acids was prepared and the inhibitory activities of its members on IL-1 generation were evaluated both by in vitro systems using human monocytes and/or rat exudated macrophages stimulated with LPS, and by an in vivo system using the rat CMC-LPS air-pouch model. Many compounds in this series were found to be potent inhibitors of IL-1 generation both in vitro and in vivo. ...
