Quaternary ammonium compounds

Abstract

Novel quaternary ammonium compounds of the formula and any stereoisomers thereof, wherein R1, R2 and R3 independently represent C1-C6 alkyl, optionally substituted with phenyl or hydroxyl, or both, and wherein any two of R1, R2 and R3 may form a ring together with the quaternary ammonium nitrogen; R4 represents —H, —CH3, or —CO—R4-1, wherein R4-1 represents —(C1-C4 alkyl), —(C1-C4 alkoxy), or —NR4-2R4-3, wherein R4-2 and R4-3 independently represent —H or —(C1-C4 alkyl); R5, R6 and R7 independently represent —H, —OCH3, —OH, —CONH2, —SO2NH2, —F, —Cl, —Br, —I, —CF3, or —(C1-C4 alkyl), optionally substituted with one or two —OH, —(C1-C4 alkoxy), —COOH, or —CO—O—(C1-C3 alkyl); and X− represents an anion of a pharmaceutically acceptable acid, the compounds for use as medicaments, use of the compounds for the manufacture of specific medicaments, and pharmaceutical compositions comprising the compounds. The present invention also concerns a method of treatment involving administration of the compounds.
