Antimicrobial and cytotoxic activity of (thio)alkyl hexopyranosides, nonionic glycolipid mimetics

A series of 19 synthetic alkyl and thioalkyl glycosides derived from D-mannose, D-glucose and D-galactose and having C10–C16 aglycone were investigated for cytotoxic activity against 7 human cancer and 2 non-tumor cell lines as well as for antimicrobial potential on 12 bacterial and yeast strains. The most potent compounds were found to be tetradecyl and hexadecyl β-D-galactopyranosides (18, 19), which showed the best cytotoxicity and therapeutic index against CCRF-CEM cancer cell line. Similar cytotoxic activity showed hexadecyl α-D-mannopyranoside (5) but it also inhibited non-tumor cell lines. Because these two galactosides (18, 19) were inactive against all tested bacteria and yeast strains, they could be a target-specific for eukaryotic cells. On the other hand, β-D-glucopyranosides with tetradecyl (11) and hexadecyl (12) aglycone inhibited only Gram-positive bacterial strain Enterococcus faecalis. The studied glycosides induce changes in the lipid bilayer thickness and lateral phase separation at high concentration, as derived from SAXS experiments on POPC model membranes. In general, glucosides and galactosides exhibit more specific properties. Those with longer aglycone show high cytotoxicity and therefore, they are more promising candidates for cancer cell line targeted inhibition.

Novel mixed-heteroatom macrocycles via templating: A new protocol

A series of novel thiadiaza and triaza crown ether attached galactose- and glucose-based glycolipids is synthesized, applying a new strategy. The key step is the formation of α-chloroacetamido precursors (14 and 21) from selectively protected bis(cyanomethyl)-glycolipids (13 and 19) in two steps. The cyclization reaction furnishes good yields in relatively short times in aqueous ethanol or acetonitrile. To generalize this method, macrocycles 3 and 25 are reported as well. Attempts to use the traditional synthetic approaches for cyclization failed to provide reasonable yields.

Easy production of a glycolipid analogue using animal cells in culture

A glycolipid analogue, GM4-type ganglioside, was obtained by a combination of chemical synthesis and biosynthetic processes in animal cells with dodecyl β-d-galactoside (Gal C12) as primer. The primer was conveniently prepared in two steps: glycosylation, followed by deacetylation. The primer was introduced to mouse melanoma B16 cells to serve as substrate for cellular, enzyme-catalyzed glycosylation. Incubation of the cells in the presence of the primer resulted in sialylation of the galactose residue to afford a GM4 analogue that was released from the cells to the culture medium. The strategy of preparation of the GM4 analogue described in this study is a viable alternative to the existing methods. The saccharide-primer method is fast, convenient, not requiring expensive enzymes and glycosyl donors, and highly stereoselective.
