Dihydroxybenzamide derivatives, having anti-inflammatory activity and therefore useful in medecine, are represented by the formula (I):
wherein R' represents hydrogen or alkyl of 1 to 4 carbon atoms and R2 represents straight chain-alkyl of 4 to 12 carbon atoms, branched chain-alkyl of 4 to 12 carbon atoms, cyclo- alkyl of 4 to 12 carbon atoms,
wherein n is an integer of 1 to 6, or substituted or unsubstituted pyridyl, or R' and R2 together with the nitrogen atom to which they are attached represent a group of the formula -N-X-Y wherein X represents nitrogen or methine and Y represents hydrogen, alkyl of 1 to 6 carbon atoms or phenyl.
二羟基苯甲酰胺衍生物具有抗炎活性,因此可用于医疗,其代表式为 (I):
其中 R' 代表氢或 1 至 4 个碳原子的烷基,R2 代表 4 至 12 个碳原子的直链烷基、4 至 12 个碳原子的支链烷基、4 至 12 个碳原子的环烷基、
其中 n 为 1 至 6 的整数,或取代或未取代的吡啶基,或 R' 和 R2 与它们所连接的氮原子一起代表式 -N-X-Y 的基团,其中 X 代表氮或甲烷,Y 代表氢、1 至 6 个碳原子的烷基或苯基。
