Synthesis of N-substituted iminosugar derivatives and their immunosuppressive activities

Several N-alkyl and hydroxyethyl-substituted iminosugar derivatives, including l-altro and d-galacto epimers, were synthesized and the effects of these synthetic iminosugars on proliferation of mouse splenocytes were evaluated in the MTT assay. The experimental data demonstrated that the N-alkylated d-galacto iminosugars showed better inhibitory activities than l-altro analogues, which might hold potential as immunosuppressive agents.
