Abstract

The facile synthesis of water-soluble mitochondria targeting thioglycosylated BODIPYs is reported. Thioglycosylated BODIPYs were synthesized in 25-26% yields via thioglycosylated dipyrromethanes in four steps. The dipyrromethanes and thioglycosylated BODIPYs were characterized by various techniques including HRMS, NMR spectroscopy and X-ray crystallography. In-vitro cellular investigations in skin keratinocyte (HaCaT) and cervical (HeLa) cancer cells revealed significant cytotoxicities with IC50 values between 23.83 to 48.61 mu M. The flow cytometry experiments revealed significant cellular uptake of thioglycosylated BODIPYs into HaCaT cells and thioglucosyl substituted BODIPY (9) showed higher cellular uptake and ROS generation than the rest of the molecules. The highlight of this study is the mitochondrial targeting by the neutral BODIPYs, as judged by the colocalization experiments using confocal microscopy.
