The combination of these structural features makes them promising candidates for the treatment of a variety of conditions, spanning from cancer and inflammatory disorders to parasite infections. The exacerbated anomeric effect associated to the putative sp(2)-hybridized N-atom imparts chemical and enzymatic stability to sp(2)-IGLs and warrants total alpha-anomeric stereoselectivity in the key glycoconjugation step. A variety of O-, N-, C- and S-pseudoglycosides, differing in glycone configurational patterns and lipid nature, have been previously prepared and evaluated. Here we expand the chemical space of sp(2)-IGLs by reporting the synthesis of alpha-d-gluco-configured analogs with a bicyclic (5N,6O-oxomethylidene)nojirimycin (ONJ) core incorporating selenium at the glycosidic position. Structure-activity relationship studies in three different scenarios, namely cancer, Leishmaniasis and inflammation, convey that the therapeutic potential of the sp(2)-IGLs is highly dependent, not only on the length of the lipid chain (linear aliphatic C-12 vs. C-8), but also on the nature of the glycosidic atom (nitrogen vs. sulfur vs. selenium). The ensemble of results highlights the alpha-dodecylseleno-ONJ-glycoside as a promising multitarget drug candidate.
