LIGANDS AND METAL COMPLEXES THEREOF

摘要

Novel compounds of the formula where G1 and G2 are each independently -OH or -N(R2)2, provided that at least one of G1 and G2 is -N(R2)2, where each R2 is independently hydrogen, alkyl, aryl, acyl or -(A)p-Ra and the other variables are as defined in the specification and claims, and novel complexes of these compounds with metals are useful in diagnostic and therapeutic methods.
