Selective complexation of [small alpha]-amino acids and simple peptides via their carboxylate groups

Dalton Transactions - 21 August, 2014 - 05:54

In contrast to other NiII amino carboxylato or peptide complexes which typically contain five membered NO or NN chelate rings, the macrocyclic complex [Ni2L([small mu ]-Cl)]+ with its cleft-like structure enables a selective carboxylate coordination. The encapsulation of the biomolecules prevents the formation of intermolecular hydrogen bonding interactions, which in turn affects their structures and solubilities.
