  • Publication number: 20230349934
    Abstract: Mass spectrometry (MS) based systems and methods of implementing multi-stage MS/MS analysis for identification of experimental glycolipid samples. A processor communicatively coupled to a memory and a reference spectral database (1) implements a first stage analysis of glycan fragment data including determining, based on a matching reference glycan of a candidate reference glycolipid, a glycan structure of a glycan portion of the experimental glycolipid. The processor further (2) implements a second stage analysis of lipid/glycolipid fragment data including determining a lipid structure of a lipid portion of the experimental glycolipid by performing a spectral comparison of one or more MS/MS spectral values of a shifted experimental lipid fragment data with one or more MS/MS spectral values of matching reference lipid/glycolipid fragment data of the candidate reference glycolipid.

  • Publication number: 20220340612
    Abstract: Provided are methods of synthesizing glycolipids. The methods combine chemical and enzymatic transformations to rapidly provide diverse natural and functionalized glycolipids in a high convergent matter. Stepwise enzymatic elongation of a carbohydrate chain of a common glycolipid precursor, compound (1), provides glycan intermediates of Formula (II), using sugar-nucleotides as glycosyl donors and glycosyltransferases as enzymes. Also provided are glycan intermediates of Formula (II) and alkene intermediates of Formula (IV) and methods of preparing same.

  • Publication number: 20190247495
    Abstract: Described herein are compounds for use in vaccine compositions which contain natural or synthetic carbohydrate antigens. Such vaccines may be highly immunologically active due to the conjugation with an immune-stimulating protein or with a monophosphorylated lipid A derivative, and may be self-adjuvanting due to the presence of a monophosphorylated lipid A derivative. Treatments for cancer and fungal and bacterial infections are described herein.
