Provisos are given. Full definitions are given in the "Definitions" section. Independent claims are also included for: (1) physiologically acceptable salts of (I) with inorganic or organic acids; (2) a glucopyranosyl-substituted benzene derivatives of formula (II); (3) composition containing (I) or a physiologically acceptable salt optionally together with one or more inert carriers and/or diluents; (4) process for preparing a composition comprising the step of incorporating one or more inert carriers and/or diluents into the composition by a non-chemical method. (5) a benzene derivatives of formula (IV); (6) the preparation of (I); (7) the preparation of (II) comprises an organometallic compound (V) which may be obtained by halogen-metal exchange or by the insertion of a metal in the carbon-halogen bond of (IV) and optionally subsequent transmetallation, is added to a gluconolactone of formula (VI) then reacting the adduct obtained with water or an alcohol of formula (R-a-OH), in the presence of an acid and optionally the product obtained in the reaction with water is converted in a subsequent reaction with an acylating agent to give (II); and (8) a pharmaceutical composition for use as a diuretic or hypertensive, the composition comprising (I). R-s : H, 1-4C alkyl, (1-8Calkyl)carbonyl, (1-18C-alkyl)oxycarbonyl, arylcarbonyl or aryl-(C1 3-alkyl)-carbonyl (where the alkyl or aryl groups may be mono- or polysubstituted by halo); either R-8a-R-8d : R 6>, R-7a-R-7c or denote a benzyl group or a R-aR-bR-cSi group or a ketal or acetal group; or R-8a-R-8d : may form a cyclic ketal or acetal group or a 1,2-di(1-3C-alkoxy)-1,2-di(13C-alkyl)-ethylene bridge, (while the above-mentioned ethylene bridge forms, together with two oxygen atoms and the two associated carbon atoms of the pyranose ring, a substituted dioxane ring and alkyl, aryl and/or benzyl groups may be mono- or polysubstituted by halogen or 13C-alkoxy and benzyl groups may also be substituted by a di-(1-3C-alkyl)amino group); R-a, R-b, R-c : 1-4C alkyl, aryl or aryl-1-3C-alkyl; and aryl : phenyl (preferred) or naphthyl groups. [Image] [Image] ACTIVITY : Antidiabetic; Vasotropic; Analgesic; Antianginal; Antilipemic; Antiarteriosclerotic; Anorectic; Cardiant; Antiinflammatory. MECHANISM OF ACTION : Sodium-dependent glucose cotransporter inhibitor. The ability of (I) to inhibit sodium-dependent glucose cotransporter was tested in biological assays. The results showed that (I) exhibits a median effective concentration value of less than 50 nM.
