SURFACTANT PREPARATION PROCESS
An enzymatic process for the preparation of C16 alkyl polyglycosides and/or C18 alkyl polyglycosides by reacting C16 alkyl glycoside and/or C18 alkyl glycoside with a glycosyl donor containing monosaccharide residues to form an alkyl polyglycoside intermediate which can be fractionated to form an alkyl polyglycoside product, wherein the mole-average degree of polymerization mean DP) of the glycoside chains is greater than or equal to 3.0 units and the molar concentration of alkyl triglycoside (DP3) is greater than alkyl monoglycoside (DPI). The C16/C18 alkyl polyglycoside product is particularly useful in health care formulations, especially in combination with and/or as a solubilizer for active pharmaceutical ingredients (APIs).
GLYCOLIPOPEPTIDE BIOSURFACTANTS
Surfactants based on a newly discovered class of compounds include a hydrophobic lipid oligomer covalently linked to a peptide or peptide-like chain and a carbohydrate moiety, and a serine-leucinol dipeptide linked to the lipid oligomer. Such surfactants can be used to create an oil-in-water or water-in-oil emulsion by mixing together a polar component; a non-polar component; and the surfactant. Biosurfactants of the newly discovered class can be made by isolating and culturing a microorganism which produces the biosurfactant, and then isolating the biosurfactant from the culture. A microorganism can be engineered to produce biosurfactant of this newly discovered class by expressing a set of heterologous genes involved in the biosynthesis of the biosurfactant in the microorganism.

SYNTHETIC BIOMARKERS FOR DIFFERENTIAL SEROLOGICAL DIAGNOSIS OF CUTANEOUS LEISHMANIASIS (CL) CAUSED BY VARIOUS LEISHMANIA SPECIES
Disclosed are neoglycoconjugates and/or glycosides containing glycan selected from Galpα1,3Galfβ, Galpα1,6Galpα1,3Galfβ, or Galpα1,3Galfβ1,3Manpα. Methods of using the glycosides and/or neoglycoconjugates as diagnostic or prognostic biomarkers, vaccines, treating or detecting parasitic diseases, such as cutaneous leishmaniasis are disclosed.
Drug containing liver targeting specific ligand and thyroid hormone receptor agonist
Provided is a drug containing a liver targeting specific ligand and a thyroid hormone receptor agonist in its structure, which is a new drug structure formed by linking the liver targeting specific ligand with the thyroid hormone receptor agonist through a branched chain, a linker and a linking chain. Thyroid hormone receptors (TRs) are divided into two subtypes, TR-α and TR-β, wherein, TR-β is mainly expressed in liver, and TR-α is mainly expressed in heart, nervous system, etc. In certain embodiments, it is envisaged that the provided drug has the action of liver targeting, can specifically bring the thyroid hormone receptor agonist into liver, without entering heart and other issues, and may thereby avoid side effects caused by the action of the thyroid hormone receptor agonist on other issues, and maintain its therapeutic efficacy in the treatment of lipid metabolism disorders and related complications.
COMPOSITIONS AND METHODS FOR ASCAROSIDE MODIFICATION OF MAMMALIAN MICROBIOTA
Described herein are composition of ascarosides, methods of using them, and the like for inhibiting bacterial population growth or for altering the relative ratio of sub-populations of first and second bacteria in a mixed population of bacteria. The invention is particularly useful, for example, for modifying a microbiome of a patient (e.g., for treatment of gut microbiome dysfunction).
