1,3-DIHYDRO-1-(PHENYLALKYL)-2H-IMIDAZOL-2-ONE DERIVATIVES HAVING PDEIV AND CYTOKINE ACTIVITY

The present invention describes the use of compounds for the manufacture of a medicament for treating warm-blooded animals suffering from desease states related to an abnormal enzymatic or catalytic activity of phosphodiesterase IV (PDE IV), and/or disease states related to a physiologically detrimental excess of cytokines, in particular allergic, atopic and inflammatory diseases, said compounds having formula (I), the N-oxide forms, the pharmaceutically acceptable acid or base addition salts and the stereochemically isomeric forms thereof, wherein R1 and R2 each independently are hydrogen; C1-6alkyl; difluoromethyl ; trifluoromethyl; C3-6cycloalkyl; a saturated 5-, 6- or 7- membered heterocycle containing one or two heteroatoms selected from oxygen, sulfur or nitrogen; indanyl; bicyclo[2.2.1]-2-heptenyl; bicyclo[2.2.1]heptanyl; C1-6alkylsulfonyl; arylsulfonyl; or substituted C1- 10alkyl; R3 is hydrogen, halo or C1-6alkyloxy; R4 is hydrogen; halo; optionally substituted C1-6alkyl; trifluoromethyl; C3-6cycloalkyl; carboxyl; C1-4alkyloxycarbonyl; C3-6cycloalkylaminocarbonyl; aryl; Het1; or R4 is a radical of the formula: -O-R6; or -NH-R7; R5 is hydrogen, halo, hydroxy or C1-6alkyl; or R4 and R5 taken together may form a bivalent radical of the formula: -(CH2)n-; -CH2-CH2-O-CH2-CH2-; - CH2-CH2-N(R8)-CH2-CH2-; or -CH2-CH-CH-CH2-; Y is a direct bond, haloC1-4alkanediyl or C1-4alkanediyl; -A-B- is a bivalent radical of the formula: -CR9=CR10-; or -CHR9-CHR10; and L is hydrogen; optionally substituted C1-6alkyl; C1-6alkylcarbonyl; C1- 6alkyloxycarbonyl; optionally substituted C3-6alkenyl; optionally substituted piperidinyl; C1-6alkylsulfonyl or arylsulfonyl; aryl is optional ly substituted phenyl; Het1 is morpholinyl or optionally substituted pirydinyl, -furanyl, -thienyl, -hydroxypyridinyl, -imidazolyl, -thiazolyl, - oxazolyl, -isoquinolinyl, -quinolinonyl, -piperidinyl, or -piperazinyl; Het2 is morpholinyl or optionally substituted piperidinyl; -piperazinyl, - pyridinyl, -furanyl or -thienyl. The present invention also relates to new compounds having PDE IV and cytokine inhibiting activity, processes f or their preparation and compositions comprising said new compounds.
