- Lanthanide(III) complexes with a reinforced cyclam ligand show unprecedented kinetic inertness
-
Lanthanide(III) complexes of a cross-bridged cyclam derivative containing two picolinate pendant arms are kinetically inert in very harsh conditions such as 2 M HCl, with no dissociation being observed for at least 5 months. Importantly, the [Ln(dota)]su

- TREATMENT AGENT FOR DIAGNOSIS OR TREATMENT OF DISEASE ASSOCIATED WITH INTEGRIN
-
PROBLEM TO BE SOLVED: To provide a treatment agent for diagnosis or treatment of disease associated with integrin. SOLUTION: A treatment agent comprises a complex of a compound represented by formula (1) or salt thereof and metal. In the formula (1), A1 is a chelate group; R1 and R2 independently represent H, alkyl, or an amino protective group; Z1-Z5 independently represent N or CR3; R3 is H or a substituted/unsubstituted C1-6 alkyl group or the like; L1 is a group represented by formula (3); L2 and L3 independently represent a substituted/unsubstituted C1-6 alkylene group. In the formula (3), R13-R16 independently represent H, alkyl or the like. SELECTED DRAWING: None COPYRIGHT: (C)2017,JPOandINPIT

New cross-bridged tetraamine ligands (bicyclo[6.6.2], [6.5.2] and [5.5.2] systems) are synthesized; complexation of CuII and NiII demonstrates that the ligands coordinate selected metals in a cleft.
