| abstract |
The invention relates to new derivatives of general formula I n<IMAGE>n in whichn - R1 represents H or a C1-4 alkyl;n - R2 represents a benzoyl, benzyl or alpha -hydroxybenzyl radical, it being possible for the aromatic ring to be substituted with a halogen atom;n - R3 and R4, which may be identical or different, represent hydrogen or a lower alkyl or alkenyl radical or, together and with the formamidine function, form a heterocycle;n - R5 represents hydrogen or a C1-4alkyl radical or, with R4, forms a double bond (-N=R4)in the case of pseudoaromatic heterocycles;n - n = 0 or 1;n - A represents a linear or branched C1-4 alkylene group; andn - X represents hydrogen, a halogen, a C1-4 alkyl, a C1-4 alkoxy or a nitro group. n<??>The derivatives of general formula I are employed alone or in combination with other active principles for preparing medicinal products which are usable in the treatment of gastrointestinal pathology. |
