A carboxylic acid compound of the formula (I-a)
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.
The carboxylic acid compound of the formula (I-a) can be used for making an amide compound of the formula (I):
wherein R, A, X, R1, R2, R3 and R4 are as described above and 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-α, GM-CSF and the like, and are useful for the prophylaxis and treatment of rheumatic diseases, arthritis due to gout and the like.
式(I-a)的羧酸化合物
其中 R 是氨基等,A 是亚烷基等,X 是 O、S 等,M 是芳基等,R1、R2、R3 和 R4 是 H、羟基等。
式(I-a)的羧酸化合物可用于制造式(I)的酰胺化合物:
其中 R、A、X、R1、R2、R3 和 R4 如上所述,R5 为 H、烷基等,m 为 0-6 的整数,R6 为任选取代的芳基等,R7 为 H、任选取代的烷基等。这些酰胺化合物对直接或间接参与炎症的细胞因子,如 IL-8、IL-1、IL-6、TNF-α、GM-CSF 等具有卓越的抑制作用,可用于预防和治疗风湿性疾病、痛风引起的关节炎等。
