New derivatives of N ‐benzo[ d ]isothiazol‐3‐yl‐benzamidine 6 a were synthesized as nonacidic anti‐inflammatory/antidegenerative agents. We investigated the influence of the amidines 6 a – j on the production of NO, PGE 2 , MMP‐3, COX‐2, ROS, and GAGs, key molecules involved in cartilage destruction in osteoarthritic diseases. The antidegenerative properties of the novel designed derivatives 6 b – j were improved with respect to N ‐benzo[ d ]isothiazol‐3‐yl‐benzamidine 6 a . All of the compounds 6 a – j promoted the reduction of most of the IL‐1β‐induced harmful effects. Derivatives 6 d , 6 h , and 6 j were the most potent of all the tested compounds, particularly in the human chondrocyte culture model.
