Design, synthesis and biological evaluation of fucose-truncated monosaccharide analogues of ipomoeassin F
by Zong, Guanghui; Hirsch, Melissa; Mondrik, Collin; Hu, Zhijian; Shi, Wei
Ipomoeassin F is a plant-derived macrocyclic glycolipid with single-digit nanomolar IC50 values against cancer cell growth. In previous structure-activity relationship studies, we have demonstrated that certain modifications around the fucoside moiety did not cause significant cytotoxicity loss. To further elucidate the effect of the fucoside moiety on the biological activity, we describe here the design and synthesis of several fucose-truncated monosaccharide analogues of ipomoeassin F. Subsequent biological evaluation strongly suggests that the 6-membered ring of the fucoside moiety is essential to the overall conformation of the molecule, thereby influencing bioactivity.
