This work presents the synthesis and cytotoxicity of acetyl, propionyl, and butyryl esters of monofluorinated, difluorinated, and trifluorinated analogues of N-acetyl-D-glucosamine and N-acetyl-D-galactosamine. The cytotoxicity is expressed as IC50 values against the MDA-MB-231 cancer cell line (triple-negative breast cancer) and the HEK-293 non-cancerous cell line. It was confirmed that fluorination indeed enhances cytotoxicity especially for D-galactosamine analogues. In contrast to nonfluorinated analogues, no positive correlation between the ester alkyl chain length and cytotoxicity was observed as some acetyl esters and propionyl esters were more cytotoxic than butyryl esters. In vitro experiments indicate that recently discovered3 S-glyco-modification is an improbable cause of the observed cytotoxicity.
