A class of N,N'-cycloalkyl/alkyl benzamides of certain 1H-imidazo[4,5-b]pyridine and 3H-imidazo[4,5-b]pyridine compounds is described for treating cardiovascular and immuno-inflammatory related disorders mediated by platelet activating factor (PAF). Compounds of particular interest are those of the formula: ##STR1## wherein each of X.sup.a and X.sup.b is independently selected from nitrogen atom and --CH--, with the proviso that when one of X.sup.a and X.sup.b is selected as nitrogen atom, then the other of X.sup.a and X.sup.b must be --CH--; wherein R.sup.1 is selected from hydrido, alkyl, hydroxyalkyl, alkoxyalkyl, phenyl, halophenyl, alkylsilyloxyalkyl, amino, monoalkylamino, dialkylamino, aminoalkyl, monoalkylaminoalkyl and dialkylaminoalkyl; wherein each of R.sup.5, R.sup.6, R.sup.7 and R.sup.8 is independently selected from hydrido, hydroxy, alkyl, alkoxy, fluoro, chloro, bromo, haloalkyl, alkylthio, alkoxyalkyl, hydroxyalkyl, alkylthioalkyl, cyano, amino, monoalkylamino and dialkylamino; wherein each of R.sup.9 and R.sup.10 is independently selected from hydrido, alkyl, cycloalkyl, bicycloalkyl, heteroaryl, aryl, alkenyl and cycloalkenyl, and wherein any of said R.sup.9 and R.sup.10 substituents may be further substituted or a pharmaceutically-acceptable salt thereof.
本文描述了一类特定的1H-咪唑[4,5-b]吡啶和3H-咪唑[4,5-b]吡啶化合物的N,N'-环烷基/烷基苯甲酰胺,用于治疗由血小板活化因子(PAF)介导的心血管和免疫炎性相关疾病。特别感兴趣的化合物是以下式子的化合物:##STR1## 其中X.sup.a和X.sup.b各自独立选择为氮原子和--CH--,但要注意,当X.sup.a和X.sup.b中的一个选择为氮原子时,另一个必须为--CH--;R.sup.1选择自氢基,烷基,羟基烷基,烷氧基烷基,苯基,卤代苯基,烷基硅氧烷基,氨基,单烷基氨基,双烷基氨基,氨基烷基,单烷基氨基烷基和双烷基氨基烷基;R.sup.5,R.sup.6,R.sup.7和R.sup.8各自独立选择自氢基,羟基,烷基,烷氧基,氟基,氯基,溴基,卤代烷基,烷硫基,烷氧基烷基,羟基烷基,烷硫基烷基,氰基,氨基,单烷基氨基和双烷基氨基;R.sup.9和R.sup.10各自独立选择自氢基,烷基,环烷基,双环烷基,杂环芳基,芳基,烯基和环烯基,其中任何一个R.sup.9和R.sup.10取代基都可以进一步取代,或其药学上可接受的盐。
