Herein, we design and synthesize a series of photoactivatable beta-diarylsydnone-l-alanines (DASAs), which have excellent photo-reactivity with high fluorescence turn-on toward alkenes in a biocompatible environment. The environmental sensing properties of the resulting fluorescent pyrazoline-alanine facilitate its probing capability. By introducing the DASA residue on the side chain of linear peptides, the macrocyclic peptides resulting from the in situ photo-cyclization toward the alkene residue exhibited fluorogenic translocation through live cell membranes.
