Compounds of the formula I ##STR1## or pharmaceutically acceptable salts, hydrates, stereoisomers, optically active isomers, geometrical isomers or tautomeric forms thereof are disclosed wherein R is hydrogen or lower alkyl R.sup.1 is hydrogen, lower alkyl, styryl, or a carboxylic acid; or R and R.sup.1 together form a group of the formula --(CH.dbd.CH).sub.2 -- and in this case the broken line represents a further C--C bond, while in all other cases there is a single bond between positions 6 and 7; R.sup.2 is hydrogen, lower alkyl or hydroxy; R.sup.3 is hydrogen, lower alkyl, aryl, lower alkanoyl, carboxyl or a carboxyl acid derivative or a group of the formula --(CH.sub.2)m--COOH or a derivative thereof formed in the carboxylic group; n=1-3; R.sup.4 is hydrogen, lower alkyl which can be substituted by hydroxy or carboxy; trifluoromethyl, substituted or unsubstituted aryl, phenyl-lower alkyl or substituted or an unsubstituted heterocyclic group; R.sup.5 is hydrogen, lower alkanoyl, substituted or unsubstituted benzoyl or heteroaryl; or R.sup.4 and R.sup.5 together with the adjacent nitrogen atom form a piperidino, pyrrolidino or morpholino ring; or R.sup.4 and R.sup.5 together with the adjacent nitrogen atom form a group of the formula ##STR2## wherein R.sup.6 is hydrogen and R.sup.7 is substituted or unsubstituted phenyl; and Z is oxygen. The new compounds are useful for treating asthma.
本发明涉及化合物I的公式##STR1##或其药学上可接受的盐、水合物、立体异构体、光学活性异构体、几何异构体或其互变异构体,其中R为氢或较低烷基,R.sup.1为氢、较低烷基、苯乙烯基或羧酸;或者R和R.sup.1一起形成一个式--(CH.dbd.CH).sub.2 -的基团,在这种情况下,虚线代表进一步的C--C键,而在所有其他情况下,在6位和7位之间有一个单键;R.sup.2为氢、较低烷基或羟基;R.sup.3为氢、较低烷基、芳基、较低烷酰基、羧基或羧酸衍生物或一个式--(CH.sub.2)m--COOH的基团或在羧基中形成的衍生物;n=1-3;R.sup.4为氢、可被羟基或羧基取代的较低烷基;三氟甲基、取代或未取代的芳基、苯基-较低烷基或取代或未取代的杂环基;R.sup.5为氢、较低烷酰基、取代或未取代的苯甲酰基或杂芳基;或者R.sup.4和R.sup.5与相邻的氮原子一起形成哌啶基、吡咯啉基或吗啉基;或者R.sup.4和R.sup.5与相邻的氮原子一起形成一个式##STR2##其中R.sup.6为氢,R.sup.7为取代或未取代的苯基;Z为氧。这些新化合物对治疗哮喘有用。
