The present invention provides compounds of the general formula (I) ##STR1## and physiologically acceptable salts and bioprecursors thereof in which ##STR2## represents either ##STR3## R.sup.1 represents hydrogen, halogen, C.sub.1-4 alkoxy, hydroxy, alkyl, R.sup.4 CH(OH)--, cyano or R.sup.5 CONH--, R.sup.2 and R.sup.3, which may be the same or different, each represents a straight or branched chain alkyl group or alkenyl group or R.sup.2 and R.sup.3 may, together with the nitrogen atom to which they are attached, form a saturated heterocyclic ring containing from 5 to 7 members which may optionally contain an oxygen atom; R.sup.4 represents hydrogen or alkyl; and R.sup.5 represents hydrogen, alkyl or C.sub.1-4 alkoxy. The compounds have been shown to exhibit H.sub.1 -antagonist activity in standard pharmacological tests.
本发明提供了一般式(I)的化合物及其生理上可接受的盐和生物前体,其中##STR2##表示##STR3##,R1表示氢、卤素、C.sub.1-4烷氧基、羟基、烷基、R.sup.4 CH(OH)--、氰基或R.sup.5 CONH--,R.sup.2和R.sup.3,可以相同也可以不同,分别表示直链或支链烷基或烯基,或R.sup.2和R.sup.3可以与它们所连接的氮原子一起形成一个饱和的杂环环,该杂环环含有5到7个成员,可以选择性地包含一个氧原子;R.sup.4表示氢或烷基;R.sup.5表示氢、烷基或C.sub.1-4烷氧基。这些化合物已被证明在标准药理学测试中表现出H.sub.1-拮抗剂活性。
