Design and Synthesis of 24-Fluorinated Bafilomycin Analogue as an NMR Probe with Potent Inhibitory Activity to Vacuolar-type ATPase
A fluorine-labeled bafilomycin analogue was designed and convergently synthesized from three segments via the Stille coupling, macrolactonization, and diastereoselective aldol reaction. The V-ATPase inhibitory activity of the analogue was comparable to that of the natural product, indicating its utility as a potential molecular probe for investigating the inhibition mechanism of bafilomycin by NMR.
