Elevated hyaluronan expression is a hallmark of many types of cancer. Therefore, inhibition of hyaluronan biosynthesis can potentially slow the growth of tumor cells. Herein, we explore a chain termination strategy to reduce hyaluronan synthesis by tumor cells. Several analogs of glucosamine were prepared, which contained modifications at the C-3 positions. These analogs can possibly cap the nonreducing end of a growing hyaluronan chain, thus lowering the amount of hyaluronan synthesized. Upon incubation with pancreatic cancer cells, a fluorine-containing glucosamine analog was found to exhibit significant inhibitory activities of hyaluronan synthesis. Furthermore, it drastically reduced the proliferation of cancer cells. Supplemental materials are available for this article.

The intramolecular (1→4) glucosylation of partially protected alkyl glucosides and glucosamines with phenyl 1-thioglucoside that is preconnected via its position 2 by a succinyl spacer to positions 3 of the glucosyl acceptor affords the α-linked disaccharides. The anomeric selectivity depends on the stereochemistry of the donor-acceptor-interaction and is not governed by neighboring group participation. In contrast, connecting the glucosyl donor by the succinyl bridge to position 6 of the glucosamine acceptor results in an α/β-mixture of the corresponding disaccharides upon intramolecular glycosylation.
