Abstract
La invención se refiere a novedosos derivados de catecol de la fórmula general I en que los radicales de ácidos azometin-carboxilicos, ácidos azobencennocarboxilicos, benzhidrazonas, ácidos aminobenzoicos, aminoácidos o dipétidos, ácidos pirrolidin carboxilicos y/o oxazolidincarboxilicos así como radicales de formilcaboximetiloximas actúan como elementos estructurales y sus conjugados con sustancias activas, particularmente antibióticos. Los compuestos de la presente invención son eficaces como sideróforos en el caso de cepas bacterianas negativas, particularmente pseudomonadáceas, cepas de E, coli, salmonella klebsiella y proteus y en forma de sus conjugados con sustancias activas, por ejemplo antibióticos (como "conjugados de sideróforo") pueden introducir estas en la célula bacteriana y mejorar su eficacia antibacteriana o promoverla en parte también frente a otras cepas de bacterias resistentes a B-lactamas. Además, estos compuestos son adecuados como quelatantes de hierro para la utilización en enfermedades producidas en trastornos del metabolismo del hierro (gráfico), siendo R1-oh u O- acilo y R2 en posición 3 y/o 4 radicales de ácidos azometincarboxilicos aromáticos radicales de ácidos azobencenocarboxilicos, radicales de benzohidrazona, radicales de ácidos amononenzoicos, radicales de aminoácidos, radicales de ácidos pirrolidin y/o oxazolidincarboxilicos y radicales activas, particularmente antibióticos. Estos compuestos pueden existir en forma de ácidos libres en forma de sus sales o como ésteres fácilmente disociables.The invention relates to novel catechol derivatives of the general formula I in which the radicals of azomethinecarboxylic acids, azobenzenecarboxylic acids, benzhydrazones, aminobenzoic acids, amino acids or diphetides, pyrrolidine carboxylic acids and / or oxazolidinecarboxylic acids as well as formyl carboxymethyl radicals act as structural elements and their conjugates with active substances, particularly antibiotics. The compounds of the present invention are effective as siderophores in the case of negative bacterial strains, particularly pseudomonaceae, strains of E, coli, salmonella klebsiella and proteus and in the form of their conjugates with active substances, for example antibiotics (as "siderophore conjugates ") can introduce these into the bacterial cell and improve its antibacterial efficacy or promote it in part also against other strains of bacteria resistant to B-lactams. Furthermore, these compounds are suitable as iron chelators for use in diseases caused by disorders of iron metabolism (graph), with R1-oh or O-acyl and R2 being in position 3 and / or 4 radicals of aromatic azomethincarboxylic acids of azobenzenecarboxylic acids, benzohydrazone radicals, ammononenzoic acid radicals, amino acid radicals, pyrrolidin and / or oxazolidinecarboxylic acid radicals and active radicals, particularly antibiotics. These compounds can exist in the form of free acids in the form of their salts or as easily dissociable esters.
