A compound of the formula ##STR1## wherein A.sup.1 and A.sup.2 are independently N or CH; B is a covalent bond or C.dbd. O; R.sup.1 is hydrogen or C.sub.1 -C.sub.6 alkyl; R.sup.2 is hydrogen, fluorine, chlorine, bromine, trifluoromethyl, C.sub.1 -C.sub.4 alkyl, C.sub.1 -C.sub.4 alkoxy, or C.sub.1 -C.sub.4 alkylthio; R.sup.3 is ##STR2## wherein R.sup.4 is phenyl optionally substituted; X is oxygen or sulphur; Y is hydrogen; or Y forms an indole group with the carbon on the ortho position of the phenyl in R.sup.4 ; or a pharmaceutically acceptable base salt thereof when R is hydrogen; with the proviso that when B is a covalent bond, A.sup.1 and A.sup.2 are each CH, and use for the inhibition of aldose reductase activity.
式##STR1##中的化合物,其中A.sup.1和A.sup.2分别独立地为N或CH;B是共价键或C.dbd.O;R.sup.1是氢或C.sub.1-C.sub.6烷基;R.sup.2是氢、氟、氯、溴、三氟甲基、C.sub.1-C.sub.4烷基、C.sub.1-C.sub.4烷氧基或C.sub.1-C.sub.4烷硫基;R.sup.3是##STR2##其中R.sup.4是苯基,可选择地取代;X是氧或硫;Y是氢;或者Y与R.sup.4中苯基的邻位碳形成吲哚基团;或其在R为氢时的药学上可接受的盐;但是当B是共价键时,A.sup.1和A.sup.2各自为CH,并用于抑制醛糖还原酶活性。
