The present invention relates to novel phenoxy derivatives represented by the formula (I): ##STR1## wherein: A is an imidazolyl group, a pyridyl group, a pyridyloxy group, an oxo-substituted chromenyloxy group, a lower alkyl group, an amino group which may be substituted with a phenyl group or a lower alkyl group, or a carbamoyl group substituted with a cyclohexylamino group or an imidazolylalkyl group; B is a single bond, a thiazolyl group which may be substituted with a lower alkyl group, a group represented by the formula: --(CH.sub.2).sub.n --O--, --(CH.sub.2).sub.n CONH(CH.sub.2).sub.k -- or --(CH.sub.2).sub.n --N(R.sup.4)-- wherein k is 0 or an integer of 1 to 5, n is an integer of 1 to 6 and R.sup.4 is hydrogen or a lower alkyl group; m is 0 or an integer of 1 to 6; R.sup.1 is a hydroxyl group, an amino group or a lower alkoxy group; R.sup.2 and R.sup.3 which may be the same or different, represent a hydrogen atom or a lower alkyl group hereafter the same: and salts thereof. In the definition of the groups appearing in the formulae in the specification, the term "lower" refers to a straight or branched carbon chain having 1 to 5 carbon atoms, preferably 1 to 3 carbon atoms. Accordingly, specific examples of lower alkyl groups include a methyl group, an ethyl group, a propyl group, an isopropyl group, a butyl group, an isobutyl group, a sec-butyl group, a tert-butyl group, a pentyl (or amyl) group, an isopentyl group, a neopentyl group, a tert-pentyl group, etc.
本发明涉及由式(I)表示的新型苯氧衍生物:##STR1## 其中:A是咪唑基团,吡啶基团,吡啶氧基团,氧代取代的香豆素氧基团,低碳基,氨基,该氨基可以被苯基或低碳基取代,或者是用环己氨基基团或咪唑基烷基基团取代的氨甲酰基基团;B是单键,可以被低碳基取代的噻唑基团,或由式表示的基团:--(CH.sub.2).sub.n --O--,--(CH.sub.2).sub.n CONH(CH.sub.2).sub.k --或--(CH.sub.2).sub.n --N(R.sup.4)--,其中k为0或1至5的整数,n为1至6的整数,R.sup.4为氢或低碳基;m为0或1至6的整数;R.sup.1为羟基,氨基或低烷氧基;R.sup.2和R.sup.3可以相同也可以不同,在此后均表示氢原子或低碳基;以及其盐。在规范中出现的基团的定义中,“低”一词是指具有1至5个碳原子的直链或支链碳链,最好是1至3个碳原子。因此,低碳基的具体例子包括甲基基团,乙基基团,丙基基团,异丙基基团,丁基基团,异丁基基团,仲丁基基团,叔丁基基团,戊基(或戊基)基团,异戊基基团,新戊基基团,叔戊基基团等。
