PICOLINATE CROSS-BRIDGED CYCLAMS, CHELATES WITH METALLIC CATIONS AND USE THEREOF

摘要

Chelates resulting from the complexation of picolinate cross-bridged cyclams of formula (I), wherein n and the substituents L1-L4 and R1-R5 are as defined, with metallic cations. Picolinate cross-bridged cyclam ligands of formula (I), the use of chelates in nuclear medicine and the use of ligands in cations detection or epuration of effluents are also described.
