1. A compound of the formula: ##STR1## wherein the symbol of a solid line with a broken line means a single bond or a double bond, R and R' are independently selected from the group consisting of hydrogen atom, halogen atom, lower alkyl, nitro, unsubstituted amino and substituted amino, A and B are independently selected from the group consisting of hydrogen atom, lower alkyl optionally substituted with a lower cycloalkyl, aryl optionally substituted with one or more halogen atoms and the group: -Y-R.sup.2 wherein Y is lower alkylene and R.sup.2 is the group: ##STR2## wherein m is integer of 1 to 3, n is 0 or 1, Z is >N-, >CH-- or >C=, R.sup.3 is diaryl (lower) alkyl optionally substituted with one or more halogen atoms or is condensed heterocyclic group optionally substituted with oxo, with the proviso that (a) at least one of A and B is the group -Y-R.sup.2 and (b) when A is hydrogen atom and B is the group -Y-R.sup.2, then Z is >CH-- or >C= if R.sup.3 is condensed heterocyclic group optionally substituted with oxo and n is O or a pharmaceutically acceptable salt thereof. The compounds of the above formula have antiallergic activity.
一种化合物的化学式:##STR1## 其中,实线和虚线符号表示单键或双键,R和R'分别独立地选自氢原子、卤素原子、低级烷基、硝基、未取代氨基和取代氨基的群体,A和B分别独立地选自氢原子、低级烷基(可选择性地取代为低级环烷基)、芳基(可选择性地取代为一个或多个卤素原子)和群体:-Y-R.sup.2,其中Y是低级亚烷基,R.sup.2是群体:##STR2## 其中m为1至3的整数,n为0或1,Z为>N-、>CH--或>C=,R.sup.3是取代为一个或多个卤素原子的二芳基(低级)烷基或可选择性地取代为氧代的紧缩杂环基,条件是(a)A和B中至少有一个是群体-Y-R.sup.2,(b)当A为氢原子,B为群体-Y-R.sup.2时,如果R.sup.3是可选择性地取代为氧代的紧缩杂环基,那么Z为>CH--或>C=,n为O或其药学上可接受的盐。上述化合物具有抗过敏活性。
