Novel phenylene derivatives shown by the general formula ##STR1## wherein A represents a hydrogen atom, a phenyl group or a phenoxy group, n represents an integer of 3 to 10, R.sub.1 represents a hydrogen atom or a lower alkoxy group, X.sub.1 represents --CH.sub.2 CH.sub.2 --, --CH.dbd.CH--, --CONH--, .circle.B represents ##STR2## (wherein R.sub.2 represents a hydrogen atom, a halogen atom, a nitro group, etc.), ##STR3## (wherein R.sub.3 represents a hydrogen atom, a hydroxyl group or a lower alkoxy group), X.sub.2 represents --CH.dbd.CH--, --CH.sub.2 CH.sub.2 --, etc. and D represents a carboxy group, a lower alkoxycarbonyl group or ##STR4## which are useful as drugs, particularly SRS-A (slow reacting substance of anaphylaxis) antagonist, i.e. they are useful as prophylaxis and treatment for various allergic diseases (e.g. bronchial asthma, allergic rhinitis, urticaria) or, ischemic heart diseases, inflammation, etc. induced by SRS-A.
新型苯基衍生物的一般化学式如下所示:##STR1##其中A代表氢原子、苯基或苯氧基,n代表3到10的整数,R.sub.1代表氢原子或较低的烷氧基,X.sub.1代表--CH.sub.2 CH.sub.2 --、--CH.dbd.CH--、--CONH--,.circle.B代表##STR2##(其中R.sub.2代表氢原子、卤素原子、硝基基团等),##STR3##(其中R.sub.3代表氢原子、羟基或较低的烷氧基),X.sub.2代表--CH.dbd.CH--、--CH.sub.2 CH.sub.2 --等,D代表羧基、较低的烷氧羰基或##STR4##,这些化合物可用作药物,特别是SRS-A(过敏性缓慢反应物质)拮抗剂,即它们可用于预防和治疗各种过敏性疾病(如支气管哮喘、过敏性鼻炎、荨麻疹)或由SRS-A引起的缺血性心脏病、炎症等。
