Abstract:
Immunogenic compositions, cancer vaccines and methods for treating cancer comprising FMS, the fucose-enriched polysaccharide fraction from Reishi F3, are provided. Compositions comprise fucose-enriched Reishi polysaccharide fraction (FMS) MW = ~35kDa, wherein the FMS is isolated by size-exclusion chromatography from Reishi F3, and the FMS comprises polysaccharides having primarily a backbone selected from 1,4-mannan and 1,6-a-galactan, wherein the backbone is linked to a terminal fucose-containing side-chain. Immunogenic compositions comprising glycolipid adjuvants are provided. Antibodies generated by immunogenic compositions disclosed herein bind cancer cells comprising antigens Globo H, Globo H, Gb3, Gb4, Gb5 (SSEA-3) and SSEA-4 on the cell surface.
Abstract:
An immune composition containing Globo H or its fragment (e.g., SSEA3) and an adjuvant, e.g., a -GalCer, for eliciting immune responses against Globo H or its fragment and uses thereof in cancer treatment. Also disclosed is a method of treating cancer by inhibiting the activity of one of FUT1 and FUT2, both of which involve in Globo H biosynthesis.
Abstract:
The present disclosure relates to synthetic alpha-galactosyl ceramide (a-GalCer) analogs, and their use as immunotherapies. In one aspect, a method of activating a cytokine response in a subject includes administering an effective amount of a compound to a subject, wherein the subject has an adaptive immune system that includes a population of cells, the population including at least one lymphocyte and at least one antigen-presenting cell, and wherein the compound is represented by the structure of formula (1) wherein, n is 0 to 25; X is selected from O and S; R 1 is selected from H, CH 3 , and phenyl, where phenyl is optionally substituted with H, OH, OCH 3 , F, CF 3 , phenyl, phenyl-F, C 1 -C 6 alkyl, or C 2 -C 6 branched alkyl; R 2 is selected from OH and H; R 3 is selected from C 1 -C 15 alkyl, and phenyl, where phenyl is optionally substituted with H, OH, OCH 3 , F, CF 3 , phenyl, C 1 -C 6 alkyl, or C 2 -C 6 branched alkyl; R 4 is selected from OH, OSO 3 H, OSO 3 Na, and OSO 3 K; and R 5 is selected from CH 2 OH and CO 2 H; or a pharmaceutically acceptable salt thereof; forming a complex between the compound and the antigen-presenting cell, wherein the formation of the complex results in the activation of a receptor on the lymphocyte; and activating the lymphocyte to produce the cytokine response.

Abstract:
The present invention provides compounds which are potent inhibitors against Lpd activity, PDH activity, and/or the growth of tubercle bacillus, and thus are useful in the treatment of tuberculosis infection and associated conditions. The present invention is further directed to in vitro- and in vzivo-based methods of inhibiting Lpd and/or PDH activity. In certain embodiments, these methods are useful in inhibiting Lpd and/or PDH activity key to a pathogen' s survival.
Abstract:
Aluminum coated glass slides provide a novel glycan array platform. Specifically, aluminum coated glass slides increase sensitivity of fluorescent based assay methods. Additionally, aluminum coated glass slides allows for mass spectroscopic analysis of carbohydrates and provide a platform for examining activity of cellulases. The unique properties of ACG slides include: 1) the metal oxide layer on the surface can be activated for grafting organic compounds such as modified oligosaccharides; 2) the surface remains electrically conductive, and the grafted oligosaccharides can be simultaneously characterized by mass spectrometry and carbohydrate-binding assay; and 3) the slides are more sensitive than transparent glass slides in binding analysis.
