28145544-7	2017	(ii) Both IA and IB convert to a common component II (apparent transition pKa ~7.8 for IA and ~6.5 for IB, respectively) featuring a tridentate ligand consisting of the N-terminal amine, the Asp1-Ala2 amide and the Ala2-Pro3 carbonyl; this stereochemistry is stabilized by two five-membered chelate rings.

30239184-3	2018	Our advanced EPR spectroscopic results revealed that a chemical regulator (1) for CuII-Abeta1-16 disrupted the coordination environment of CuII in Abeta, resulting in the detachment of the primary amine at the N-terminal and a carbonyl group between Asp1 and Ala2 from the CuII center and the subsequent formation of a ternary complex, chemical regulator-CuII-Abeta1-16.
