The invention is concerned with compounds of formula ##STR1## wherein R.sup.1 is lower-alkoxy, R.sup.2 is hydroxy or lower-alkoxy, R.sup.3 is hydrogen, cyano, alkyl, alkenyl, cycloalkyl, aryl, heterocycyl, aryl-Q-alkyl, or a group of the formula --CR.sup.4 R.sup.4 'COR.sup.5 --, Q is --SO-- or --SO.sub.2 --; R.sup.4, R.sup.4 ' are each independently hydrogen, alkyl, aryl or heterocyclyl, R.sup.5 is hydrogen, alkyl, alkoxy, hydroxy, aryl or heterocycyl, or R.sup.4 and R.sup.5 together form --(CH.sub.2).sub.n --, and n is a whole number between 2 to 5 inclusive and the enantiomers, epimers, and diastereomers thereof, as well as pharmaceutically acceptable salts thereof. These compounds have valuable antibacterial activity.
该发明涉及以下结构的化合物:其中R.sup.1是较低的烷氧基,R.sup.2是羟基或较低的烷氧基,R.sup.3是氢、氰基、烷基、烯基、环烷基、芳基、杂环烷基、芳基-Q-烷基,或者是--CR.sup.4 R.sup.4 'COR.sup.5 --的结构;Q是--SO--或--SO.sub.2--;R.sup.4、R.sup.4 '分别独立地是氢、烷基、芳基或杂环烷基;R.sup.5是氢、烷基、烷氧基、羟基、芳基或杂环烷基,或者R.sup.4和R.sup.5一起形成--(CH.sub.2).sub.n--,n是2到5之间的整数,以及它们的对映体、差向异构体和药学上可接受的盐。这些化合物具有有价值的抗菌活性。
