چکیده انگلیسی
A novel enediynyl pentapeptide in the protected form 1 was synthesized and characterized. It exists predominantly in β-turn structural motif as revealed by variable temperature NMR and CD spectroscopy. In the presence of transition metal ions and gold nanoparticles, the fluorescence intensity of the peptide got enhanced with remarkable quantum yield with the Z-enediynyl -amino acid acting as a fluorophoric reporter. The interesting photophysical behaviors with alkali and alkaline earth metal ions are also reported.
