Over twenty diseases are associated with amyloid deposits,such as Alzheimer’s disease,Parkinson′s disease and Huntington’s disease,*** of amyloid proteins would lead to the formation of toxic aggregates,including different oligomeric species and fibrils in vivo,which is one of the pathological hallmarks of these severe neurodegenerativeRecently,the demonstration that injection of‘strains’with different structural features into the brain of mice could cause different phenotypes,which is a typical characteristic of prions,strongly supported the prion-like mechanism of amyloidprevious studies usually generate different strains through the regulation of pH,salt concentration or temperature in *** our study,we synthesized?-amyloid（A?）phosphorylated at Ser 84 and?-Synuclein（?-Syn）phosphorylated at Ser 1295,showing that the phosphorylation can induce the formation of different strains ***,we designed and synthesized a series of inhibitors to regulate and induce degradation of A?and?-Syn.

The cationized 9-fluorenylmethoxycarbonyl (Fmoc) protected amino acids were analyzed by the electros-pray ionization tandem mass spectrometry (ESI-MS/MS). A rearrangement reaction leading to the C-terminal hydroxyl group transfer was observed. The sodium adducts of Fmoc-OH was formed. A possible rearrangement mechanism was proposed. The rearrangement reaction depended on the Fmoc group, metal ions and metal ion radius. It was shown that the Fmoc group has a strong affinity to the hydroxyl group in the gas phase.
