MULTIVALENT CHELATORS FOR MODIFYING AND ORGANIZING OF TARGET MOLECULES

摘要

Multivalent chelator compounds, containing a carbohydrate scaffold structure linked to chelator groups and coupling groups, are new. Multivalent chelator compounds of formula X m-G-CL n (I), and their tautomers, isomers, anhydrides, acids and salts, are new. G : a scaffold structure comprising a saturated 2-20C carbohydrate chain with amide-, ester- and/or ether bonds; X : a coupling group for a probe or functional unit F'; CL : a chelator group with a metal-coordinative center containing a metal ion; m : at least 1; and n : at least 2. An independent claim is also included for the preparation of (I).
