When iNKT cells are stimulated by the CD1d presented exogenous alpha-galactosylceramide, a myriad of cytokines are released that trigger a variety of immune responses. However, the invisibility and poor aqueous Solubility of alpha-galactosylceramide during bioassays have rendered it difficult to study the aforementioned biological responses. Accordingly, a biotin-labelled alpha-galactosylceramide was prepared to facilitate detection of this antigen in the immune process. The problematic low solubility was also remedies via incorporation of a truncated acyl chain. (C) 2009 Elsevier Ltd. All rights reserved.

the control of several types of immune response. As an active glycolipid antigen having α-galactosylceramide core structure, KRN7000 showed promising immunostimulation activity and was selected as an anticancer drug candidate for further clinical application. In this report, three new KRN7000 structural analogues were designed and synthesized, in which the ring oxygen of the galactopyranose residue
