The invention relates to substituted 3-phenyl-5-alkoxi-1,3,4-oxdiazol-2-ones of formula (I), wherein R<1> means substituted C1-C6-alkyl and C3-C9-cycloalkyl, R<2>, R<3>, R<4> and R<5> mean hydrogen, halogen, nitro, C1-C4-alkyl, C1-C9-alkyloxy, substituted C6-C10-aryl-C1-C4-alkyloxy, C6-C10-aryloxy, C6-C10-aryl, C3-C8-cycloalkyl or O-C3-C8-cycloalkyl or 2-oxo-pyrrolidin-1-yl, 2,5-dimethylpyrrol-1-yl or NR<6>-A-R-<7>, on the condition that R<2>, R<3>, R<4> and R<5> do not mean simultaneously mean hydrogen and at least one of the radicals R<2>, R<3>, R<4> or R<5> represents the radical 2-oxo-pyrrolidin-1-yl, 2,5-dimethylpyrrol-1-yl or NR<6>-A-R<7>, with R<6> = hydrogen, C1-C4-alkyl or substituted C6-C10-aryl-C1-C4-alkyl, A = a simple bond, COn, SOn or CONH, n = 1 or 2, R<7> = hydrogen, substituted C1-C18-alkyl,C2-C18-alkenyl, C6-C10-aryl-C1-C4-alkyl, C5-C8-cycloalkyl-C1-C4-alkyl, C5-C8-cycloalkyl, C6-C10-aryl-C2-C6-alkenyl, C6-C10-aryl, diphenyl, diphenyl-C1-C4-alkyl, indanyl or the group Het-(CH2), with r = 0, 1,2 or 3 and Het = a saturated and unsaturated 5-7 membered heterocycle which can be benzoanellated and substituted. The invention also relates to a method for producing the same. The inventive compounds have an inhibitory effect on hormone-sensitive lipase, HSL. |
