Aminocarbonyl-substituted 8-N-benzimidazoles, methods for their preparation and their use in pharmaceutical compositions
View Patent ↗The present invention comprises the use of amino-carbonyl-substituted 8-N-benzimidazoles compounds of formula I wherein R3, R4-R5, R11 and R20-R21 are hereinafter defined which display a therapeutically utilizable blood sugar-lowering action. These compounds are intended to be particularly suitable in the treatment of diabetes, carbohydrate and lipid metabolic disorders and other blood sugar complications.
1. The compound of formula I
wherein
R20 is H;
R21 is selected from the group consisting of (C 6 -C 10 )-aryl and (C 1 -C 6 )-alkylene-(C 6 -C 10 )-aryl, where the aryl radicals may be mono- or polysubstituted by F, Cl, Br, I, CN, NO 2 , SH, OH, CF 3 , (C 1 -C 6 )-alkyl, O—(C 1 -C 6 )-alkyl, or S—(C 1 -C 6 )-alkyl;
R3 is (C 2 -C 10 )-alkenyl;
R4, R5 are each H;
R11 is selected from the group consisting of F, Cl, Br, I, (C 1 -C 6 )-alkyl, (C 3 -C 8 )-cycloalkyl, NH 2 , NH(C 1 -C 6 )-alkyl, NH(C 3 -C 7 )-cycloalkyl, N((C 1 -C 6 )-alkyl) 2 and O—(C 1 -C 6 )-alkyl, where the alkyl groups may be mono- or polysubstituted by F, Cl, Br or I; and
n is 0;
or a pharmaceutically acceptable salt thereof.
2. A pharmaceutical composition comprising the compound of formula I as recited in claim 1 further combined with one or more additional solvents, bulking agents, binders, lubricants, inert diluents and/or one (or more) surfactants/dispersants, excipients, thickening agents, buffers, polymers, stabilizers, binders, flavorants, sweeteners formulated as a pharmaceutical composition for administration as a tablet, capsule, intravenous solution, transdermal gel, powder, oral solution, syrup, intranasal spray, or lozenge to a patient in need thereof.
