The condensation reactions of 2-formylpyrrole (1) or 2-formylphenanthro[9,10-c]pyrrole (2) with various aliphatic amines afforded the corresponding 2-iminopyrrole ligand precursors 3–10, which, upon stoichiometric reaction with BPh3, led to the new

The fluorescence of the four tyrosines of α-synuclein (Syn) was used for probing the earliest events preceding the fibrillation of Syn, during the onset of the so-called lag-time of fibrillation. Steady-state fluorescence experiments revealed an inc
