23578330-8	2013	Single crystal X-ray diffraction determined for [Cu(H2L1)](ClO4)2 showed the copper center in a distorted octahedral environment bound to the N4O donors of the macrobicycle and one oxygen atom from a carboxylic arm, while for [CuL2] it showed the copper center in a trigonal bipyramid geometry only bound to the donors of the macrobicycle and leaving the carboxylate arms away from the coordination sphere.	perchlorate	59-64	cullin 2	Homo sapiens	227-231	
9046106-3	1997	Some copper (II) complexes [CuL2] with SOD-like activity containing 2-methyl amino pyridine and various anions (Cl-, Br-, NO3-, ClO4-, or SO4--) were tested for their protective efficiency toward the cell damage photoinduced by CPBA.	perchlorate	128-132	cullin 2	Homo sapiens	28-32
