The present invention relates to cyclen based compounds of general formula (I), wherein X is nitrogen and Y, Z are –CH-, or X, Z are –CH- and Y is nitrogen, or X, Y are –CH- and Z is nitrogen, R1 is independently selected from H, COOH, benzyloxycarbonyl, fluorenylmethyloxycarbonyl, tert-butoxycarbonyl, methylcarbonyl, trifluoromethylcarbonyl, benzyl, triphenylmethyl, tosyl, mesyl, benzyloxymethyl, phenylsulfonyl, ethoxycarbonyl, 2,2,2-trichloroethyloxycarbonyl, methoxycarbonyl, methoxymethyloxycarbonyl, R2 is selected from H, methylcarbonyl, tert-butyldimethylsilyl, (C1-C4)alkyl, which can be linear or branched, and which can optionally be substituted with CH3O-, CH3S-, oxacyclohexyl, allyl, tert-butyldiphenylsilyl, tert-butylcarbonyl, phenylcarbonyl, nitrobenzyl, benzyloxymethyl, which can optionally be substituted with CH3O-, -NO2, fluorenylmethyloxycarbonyl, trichlorocarbonyl, trifluorocarbonyl, benzyl, tosyl, mesyl, phenylsulfonyl, allylsulphonyl, ethoxycarbonyl, 2,2,2-trichloroethyloxycarbonyl, methoxycarbonyl, methoxymethyloxycarbonyl, R3 is independently selected from H, (C1-C6)alkyl, which can be linear or branched, and which can optionally be substituted with -CH3, -C1, -F, -CN, tosyl, triisopropylsilyl, CH3O-, CH3S-, (C5-C6)cycloalkyl, which can optionally be substituted with -CH3, -C1, -F, -CN, (C6-C10)aryl, which can optionally be substituted with -CH3, -C1, -F, -CN, allyl, propargyl, fluorenylmethyl, benzoylmethyl, phenyloxymethyl, oxacyclopentyl, 2-oxo-1,2-diphenylethyl, with the proviso that where R1 is bound to nitrogen, then R1 is not COOH, with the proviso that where R1 is bound to –CH-, then R1 is independently H or COOH, and with the proviso that one R1 is COOH, and with the proviso that one –CH-R1 group is –CH2-. The invention further relates to its coordination compounds, peptides and pharmaceutical preparations, as well as to the medical use thereof.
