Compounds of the general formula: ##SPC1## Wherein X represents a 5-[1H]-tetrazolyl group, R.sub.1 represents a hydrogen atom, a halogen atom, a hydroxyl group or a group --OR.sub.2, (in which R.sub.2 may be a lower alkyl or alkenyl group containing from 1 to 6 carbon atoms optionally substituted by one or more hydroxy groups, an aryl group, an aryloxy group, an alkoxy group or a dialkylamino group) or a group --NR.sub.3 R.sub.4, in which R.sub.3 and R.sub.4 which may be the same or different, represent a hydrogen atom, a lower alkyl group containing from 1 to 6 carbon atoms, optionally substituted by a hydroxy group, or R.sub.3 and R.sub.4 together with the nitrogen atom may form a ring which may optionally be substituted with another heteroatom and pharmaceutically acceptable salts thereof. These compounds have useful immunological activity and inhibit the release of spasmogen mediators.
通式为:##SPC1## 其中X代表一个5-[1H]-四唑基团,R.sub.1代表氢原子、卤原子、羟基或基团--OR.sub.2,(其中R.sub.2可以是含有1至6个碳原子的较低烷基或烯基基团,可选地被一个或多个羟基取代,芳基、芳氧基、烷氧基或二烷基氨基基团)或基团--NR.sub.3 R.sub.4,其中R.sub.3和R.sub.4可以相同也可以不同,代表氢原子、含有1至6个碳原子的较低烷基基团,可选地被羟基取代,或R.sub.3和R.sub.4与氮原子一起可以形成一个环,该环可以可选地被另一个杂原子取代,以及其药用盐。这些化合物具有有用的免疫活性,并抑制痉挛原介质的释放。
