摘要

In previous studies, we have identified a family of benzo[b]furan and benzo[b]thiophene derivatives linked to amino sugars (1-6) that are cytotoxic to a range of cancer cell lines. We describe here an exploration of the effect of structural modification of the amino group on one of the carbohydrate residues (4-amino-2,3,4,6-tetradeoxy-alpha-l-threo-hexopyranoside) on in vitro cytotoxicity. It has been found that maintaining at least one basic functional group around the C-4 position in the carbohydrate moiety is crucial for cytotoxicity. Furthermore, it appears that modifications around the C-4 position are limited by suitable hydrophilic/hydrophobic and/or ionic interactions, as well as steric constraints.
