A compound of general formula (I) ** Formula ** where: R1 and R2 independently represent each other, a C6-C10 aryl radical optionally substituted with a group selected from a C1-C3 alkyl group, a halogen, a nitro group , a cyano group, a trifluoromethyl group, OR ', SR', SOR ', SO2R', NR'R '', C (O) R ', C (O) OR', C (O) NR'R '' or OC (O) R '; or a heteroaryl radical of 3 to 10 carbon atoms and one to five heteroatoms selected from nitrogen, oxygen and sulfur, optionally substituted with a group selected from a C1-C3 alkyl group, a halogen, a nitro group, a cyano group, a trifluoromethyl group, OR ', SR', SOR ', SO2R', NR'R '', C (O) R ', C (O) OR', C (O) NR'R '' or OC (O) R ', and where the nitrogen, carbon or sulfur atoms in the heteroaryl radical are optionally oxidized, and the nitrogen atom is optionally quaternized; A and M represent, independently of each other, a methylene group or a single bond, in which case the adjacent aromatic ring would be attached directly to the amido group; the group Y> = Z jointly and interchangeably represents an oxygen atom (-O-), a sulfur atom (-S-), a cis-vinylidene group (-CH> = CH-), an imino group (-N > = CH- or -CH> = N-), or a methine group with sp2 hybridization on the carbon atom (> = CH-); X indistinctly represents a methine group (> = CH-), a cis-vinylidene group (-CH> = CH-) or a nitrogen atom (> = N-); and W represents a hydroxyl group (-OH). |
