PROBLEM TO BE SOLVED: To provide a new or improved macromolecule delivery system for all kinds of diagnostic agents, therapeutic agents or other drugs, to improve deliverability and reduce administration volume by using a method of employing a macromolecular main chain as a delivery medium, and to provide a macromolecule relatively easily available, relatively inexpensive and worthy to be demonstrated by scientific study and medical science. SOLUTION: This new macromolecular carrier for drugs and diagnostic agents utilizes the formation of a chemical bond of new leashes to an oligomeric backbone structure. The synthesis of these leashes and their facile creation, reaction and conjugation with chelators and ligands make them very useful for use in medicine and especially in diagnostic agents.
