Abstract
Microcystin is the most prevalent toxin produced by cyanobacteria and poses a severe threat to livestock, humans and entire ecosystems. We report the preparation of a series of fluorescent microcystin derivatives by direct arginine labelling of the unprotected peptides at the guanidinium side chain. This new method allows a simple late-stage diversification strategy for native peptides devoid of protecting groups under mild conditions. A series of fluorophores were conjugated to microcystin-LR in good to very good yield. The fluoresce
