LA PRESENTE INVENCION SE REFIERE A NUEVOS DERIVADOS DE 4H-1-BENZOPIRAN-4-ONA, A UN PROCEDIMIENTO PARA SU PREPARACION, ASI COMO A SU EMPLEO, COMO ANTIINFLAMATORIOS, ANALGESICOS, INMUNOSUPRESORES Y ANTIALERGICOS. LA PRESENTE INVENCION SE REFIERE, ESPECIALMENTE, A NUEVOS COMPUESTOS DE LA FORMULA (I) EN LA QUE R1,R2,R3,R4,R5, M Y N TIENEN LOS SIGNIFICADOS QUE SE INDICAN EN LAS REIVINDICACIONES Y EN LA MEMORIA, ASI COMO A SUS SALES DE ADICION DE ACIDO FARMACOLOGICAMENTE INOCUAS. The novel 4H-1-benzopyran-4-one derivatives are used as antiinflammatories, analgesics, immunosuppressants and antiallergics. The present invention relates in particular to novel compounds of the formula I in which R1 represents hydrogen, alkyl having 1 to 6 carbon atoms, aryl-C1-C4-alkyl, substituted C1-C6-alkyl, C3-C6-cycloalkyl, C3-C6- cycloalkyl-C1-C4-alkyl, C2-C6-alkenyl, C2-C6-alkynyl, aryl, carboxyl or an aldehyde or COO-C1-C4-alkyl group, R2 represents hydrogen, alkyl having 1 to 6 carbon atoms, nitro, amino, aryl, carboxyl, di-C1-C4- alkylamino, or a halogen, R3 represents C1-C4-alkyl, substituted C1-C4- alkyl, hydroxyl, C1-C4-alkoxy, aryl-C1-C4-alkyl, nitro, amino, a C1-C4- alkyl- or di-C1-C4-alkylamino group or halogen, R4 represents hydrogen, hydroxyl, C1-C4-alkoxy, C1-C4-alkanoyloxy, C1-C4-alkoxycarbonyl, aryloxy, amino or a C1-C4-alkyl- or di-C1-C4-alkylamino group, n represents the integer 0, 1 or 2 and R5 represents hydrogen, C1-C6- alkyl, substituted C1-C6-alkyl, aryl-C1-C4-alkyl, C3-C6-cycloalkyl, C3- C6-cycloalkyl-C1-C4-alkyl, C1-C4-alkanoyl or aroyl, where the aryl group is optionally monosubstituted or polysubstituted phenyl, m denotes an integer between 0 and 3 and n denotes an integer between 0 and 2, and their pharmacologically acceptable acid addition salts.
