  • The key entity of a DCAR agonist, phosphatidylinositol mannoside Ac 1PIM 1: Its synthesis and immunomodulatory function

    Arai Y., Torigoe S., Matsumaru T., Yamasaki S., Fujimoto Y.

    Organic and Biomolecular Chemistry 18 ( 19 ) 3659 - 3663 2020.05

     View Summary

    © The Royal Society of Chemistry 2020. Ac1PIM1is a potential biosynthetic intermediate for phosphatidylinositol mannosides (PIMs) fromMycobacterium tuberculosis. We achieved the first synthesis of Ac1PIM1by utilizing an allyl-type protecting group strategy and regioselective phosphorylation of inositol. A very potent agonist of an innate immune receptor DCAR, which is better than previously known agonists, is demonstrated.

  • Design and Discovery of Covalent α-GalCer Derivatives as Potent CD1d Ligands

     View Summary

    © 2020 American Chemical Society. CD1d is a nonpolymorphic antigen-presenting protein responsible for the regulation of natural killer T (NKT) cell activation. α-Galactosyl ceramide (α-GalCer, KRN7000) is the representative CD1d ligand that can bind to the CD1d protein. The resulting complex is recognized by the T cell receptors of the NKT cell, inducing various immune responses. Previous structure-activity relationship studies of α-GalCer have revealed that the ability of NKT cells to induce cytokines depends on the ligand structure, and in particular, ligands that form more stable complexes with CD1d display potent activity. We focused on the Cys residue of the large hydrophobic pockets of CD1d (A′ pocket) and developed α-GalCer derivatives containing groups that can form covalent bonds. The assay results revealed that these ligands displayed higher levels of cytokine production and Th2 cell-type cytokine polarization response. Furthermore, the LC-MS/MS analysis indicated that the chloroacetylamide-containing ligand was covalently bound to Cys12 of CD1d, which suggests that the enhanced activities result from the formation of a stable CD1d-ligand complex. To our knowledge, this is the first ligand that allows covalent bond formation to CD1d under physiological conditions.

  • Potent Th2 Cytokine-Bias of Natural Killer T Cell by CD1d Glycolipid Ligands Based on “Anchoring Effect” of Polar Groups in Their Lipid Component.

     View Summary

    © 2018 Wiley-VCH Verlag GmbH & Co. KGaA, Weinheim Th2-biasing CD1d ligands are attractive potential candidates for adjuvants and therapeutic drugs. However, the number of potent ligands is limited, and their biasing mechanism remain unclear. Herein, a series of novel Th2-biasing CD1d glycolipid ligands, based on modification of their lipid part, have been identified. These have shown high binding affinities and efficient Th2 cytokine production. Importantly, the truncated acyl chain containing variants still retain their binding affinities and agonistic activities, which can be associated with an “anchoring effect,” that is, formation of a buried hydrogen bond between a polar group on the acyl chain and the CD1d lipid-binding pocket. The analysis indicated that the appearance rates of ligand–CD1d complexes on the cell surface were involved in Th2-biasing responses. The designed ligands, having the anchor in the shorter lipid part, are one of the most potent Th2-biasing ligands among the known ligands.

     View Summary

    © 2018 Wiley-VCH Verlag GmbH & Co. KGaA, Weinheim Sialyl-Tn (STn) is a tumor-associated carbohydrate antigen (TACA) rarely observed on healthy tissues. We synthesized two fully synthetic N-acetyl and N-propionyl STn trimer (triSTn) vaccines possessing a T-helper epitope and a TLR2 agonist, since the clustered STn antigens are highly expressed on many cancer cells. Immunization of both vaccines in mice induced the anti-triSTn IgG antibodies, which recognized triSTn-expressing cell lines PANC-1 and HepG2. The N-propionyl triSTn vaccine induced the triSTn-specific IgGs, while IgGs induced by the N-acetyl triSTn vaccine were less specific. These results illustrated that N-propionyl triSTn is a valuable unnatural TACA for anticancer vaccines.
