Substituted 3-phenyl-5-alkoxy-1,3,4-oxadiazol-2-ones of the formula 1in any optically isomeric form, and their physiologically acceptable salts, where R1 is C1-C6-alkyl, C3-C9-cycloalkyl, both of which may be unsubstituted or substituted, and R2 and R3 independently of one another are hydrogen, C6-C10-aryl, C3-C8-cycloalkyl, C6-C10-aryloxymethyl, O-benzyl, O-C6-C10-aryl, O-C3-C8-cycloalkyl, O-C1-C6-alkyl, SO2-NH-C1-C6-alkyl, SO2-NH-(2,2,6,6-tetramethylpiperidin-4-yl), SO2-NH-C3-C8-cycloalkyl, SO2-N(C1-C6-alkyl)2 or COX, where X is O-C1-C6-alkyl, NH-C1-C6-alkyl, NH-C3-C8-cycloalkyl or N(C1-C6-alkyl)2, with the proviso that the substitutents R2 and R3 may in some instances be unsubstituted or substituted and are not both simultaneously hydrogen. A process for their preparation, and their inhibitory effect on the hormone-sensitive lipase, HSL. |
