  • Patent number: 6420561
    Abstract: An amide compound of the formula (I): wherein R is amino and the like, A is alkylene and the like, X is O, S and the like, M is arylene and the like, R1, R2, R3 and R4 are H, hydroxy and the like, R5 is H, alkyl and the like, m is an integer of 0-6, R6 is an optionally substituted aryl and the like, and R7 is H, an optionally substituted alkyl and the like, a pharmaceutically acceptable acid addition salt thereof and a pharmaceutical containing same as an active ingredient. The amide compounds exhibit superior suppressive effects on cytokines directly or indirectly involved in inflammations, such as IL-8, IL-1, IL-6, TNF-&agr;, GM-CSF and the like, and are useful for the prophylaxis and treatment of rheumatic diseases, arthritis due to gout and the like.
