Using polyazamacrocyclic compounds for intracellular measurement of metal ions using MRS

摘要

The present invention relates to a method of using a polyazamacrocyclic compound or a salt thereof to measure intracellular metal ions formula where x is 2, 3 or a combination of p 2(s) and q 3(s) where p +q=y; y is 3 or 4; R is (CH2)zP(=O)R1R2; R1 is R3 or OR3 where R3 is alkyl, cycloalkyl or aryl; R2 is H, alkyl or where R4 is alkyl, cycloalkyl or aryl; and z is 1 to 3.
