ABSTRACT
Chiral lipidic dialkynylcarbinols (DACs), recently highlighted as antitumoral pharmacophores, have been conjugated to difluoroboron-dipyrromethene (bodipy), 7-hydroxy-coumarine, and 7-nitro-benzoxadiazole (NBD) fluorophore motifs through triazole clips. The labeled lipids preserve cytotoxic activity against HCT116 cells, and fluorescence microscopy of the stained cells showed clear signals in the intra-cellular membrane system. While the bodipy conjugate also labels lipid droplets very brightly, as expected, the coumarine and NBD probes appear as promising specific tools for the identification of the intra-cellular targets of DACs' cytotoxicity.
