Novel dibenz [b,e] oxepin derivatives represented by the general formula: ##STR1## wherein R.sub.11 represents an alkyl group containing 1 to 5 carbon atoms, an alkoxy group containing 1 to 5 carbon atoms, a halogen atom, a cyclohexyl group or a phenyl group; and R.sub.21 represents ##STR2## wherein X represents a hydrogen atom, a hydroxy group, an amino group or a substituted aralkyl group containing 7 to 20 carbon atoms, and n represents 0 or an integer of 1 to 3 ##STR3## or (3) --NH--(CH.sub.2).sub.n --Y, wherein Y represents an alkylamino group containing 1 to 5 carbon atoms, an aralkyl group containing 7 to 20 carbon atoms, a substituted aralkyl group, an aralkyloxy group containing 7 to 20 carbon atoms, an aralkylamino group containing 7 to 20 carbon atoms, a heterocyclic ring or a substituted heterocyclic ring, and n has the same meaning as defined before; provided that when R.sub.11 represents an alkyl group, an alkoxy group or a halogen atom, X does not represent a hydrogen atom; and the pharmaceutically acceptable acid addition salts thereof. Also disclosed are pharmaceutical compositions comprising a pharmaceutical carrier and, as an active ingredient, an effective amount of a dibenz [b,e] oxepin derivative represented by the following general formula: ##STR4## wherein R.sub.1 represents an alkyl group containing 1 to 5 carbon atoms, an alkoxy group containing 1 to 5 carbon atoms, a halogen atom, a cyclohexyl group or a phenyl group; and R.sub.2 represents ##STR5## wherein X represents a hydrogen atom, a hydroxy group, an amino group or a substituted aralkyl group containing 7 to 20 carbon atoms, and n has the same meaning as defined before ##STR6## or (3) --NH--(CH.sub.2).sub.n --Y, wherein Y and n have the same meaning as defined above; and the pharmaceutically acceptable acid addition salts thereof. Compound I, represented by the general formula (I), has antichlolinergic, antihistaminergic, antiasthmatic and antiplatelet aggregation activities, and is therefore useful as a sposmolysant, an antihistaminic, an antiasthmatic agent and as a medicament for cardiovascular or cerebrovascular diseases, respectively.
该专利涉及一种新型二苯并[b,e]噁啶衍生物,其通用式如下所示:##STR1## 其中,R.sub.11代表含1至5个碳原子的烷基、含1至5个碳原子的烷氧基、卤素原子、环己基或苯基;R.sub.21代表##STR2## 其中,X代表氢原子、羟基、氨基或含7至20个碳原子的取代芳基基团,n代表0或1至3的整数;或(3)--NH--(CH.sub.2).sub.n--Y,其中,Y代表含1至5个碳原子的烷基氨基、含7至20个碳原子的芳基烷基、取代芳基烷基、含7至20个碳原子的芳基烷氧基、含7至20个碳原子的芳基烷基氨基、杂环环或取代杂环环,n的含义与上述相同;但当R.sub.11代表烷基、烷氧基或卤素原子时,X不代表氢原子。该专利还涉及含有药物载体和作为活性成分的有效量二苯并[b,e]噁啶衍生物的制药组合物,其通用式如下所示:##STR4## 其中,R.sub.1代表含1至5个碳原子的烷基、含1至5个碳原子的烷氧基、卤素原子、环己基或苯基;R.sub.2代表##STR5## 其中,X和n的含义与上述相同;或(3)--NH--(CH.sub.2).sub.n--Y,其中,Y和n的含义与上述相同。化合物I的通用式(I)具有抗胆碱能、抗组胺能、抗哮喘和抗血小板聚集活性,因此可用作支气管扩张剂、抗组胺剂、抗哮喘剂以及心血管或脑血管疾病的药物。
