Five carbocyclic analogs of glycosylamides, N-(5a-carba-D-glycopyranosyl)-N-octadecyldodecanamides 2-6, having β-galacto, α- and β-gluco-, and α- and β-manno configurations, were synthesized by coupling of the protected anhydro derivatives 12, 15, and 21 of 5a-carba-sugars with octadecylamine, followed by N-acylation.Walden inversion of the 2-OH functions of 17 and 24 was carried out through O-sulfonylation.A bioassay (in vivo) of 5a-carbaglycosylamides showed that they are potent immunomodulators, obviously comparable to the true sugar analogs, suggesting that the 5a-carbasugar analogs may provide appropriate model compounds for biochemical studies in glycolipid chemistry. - Key Words: Carbohydrates / Pseudosugars / Cyclitols / Glycolipid analogs / Lipids, cyclitol / Glycosylamides, 5a-carba-
