摘要:The subject invention provides methods for the chemical synthesis of racemic arsinothricin (D,L-AST), the novel organoarsenical antibiotic. One is by condensation of the 2-chloroethyl(methyl)arsinic acid with acetamidomalonate, and the second involves reduction of the N-acetyl-protected derivative of hydroxyarsinothricin (AST-OH) and subsequent methylation of the resulting sodium salt of trivalent arsenic intermediate with methyl iodide. The enzyme AST N-acetyltransferase (ArsN1) was utilized to purify L-AST from racemic AST. This expedient chemical synthesis of AST provides a source of this novel antibiotic for future drug development.

摘要:The present disclosure provides a preparation method and use of a hydrogel material for growth of blood vessel organoids (BVOs). The preparation method of the hydrogel material includes: (1) synthesis of gelatin methacryloyl (GelMA), and (2) synthesis of ns-GelMA-PEO. The hydrogel material may be used for in vitro cultivation of BVOs. The hydrogel material ns-GelMA-PEO prepared by the present disclosure may significantly improve the survival and budding abilities of BVOs. The ns-GelMA-PEO provides a novel solution for in vitro cultivation of BVOs, and may well support the growth and differentiation of organoids.

摘要:The present invention discloses a preparation method of a synthetase for continuous monitoring of blood glucose. The method includes the preparation steps of step S1: hydroxylation of a glass bead; step S2: silanization of the glass bead; step S3: bonding of the glass bead to glucose; step S4: synthesis of a polymer particle on the surface of the glass bead to form a glucose synthetase; and step S5: separation of the highly specific glucose synthetase. According to the preparation method of a synthetase for continuous monitoring of blood glucose provided by the present invention, the glass bead is bonded to the glucose by activating the surface of the glass bead, and then bonded to a polymer to form the glucose synthetase. The artificial synthetase prepared by the method has low sensitivity to temperature and pH value, and can be directly used in a blood glucose electrochemical sensor.

摘要:The synthesis of the fluorinated monomer, 2-((perfluoropyridin-4-yl)amino)ethyl methacrylate, and the use of the same in the preparation of fluorinated homo- and copolymers is provided. Such monomer was designed to contain a terminal methacrylate group, allowing for polymerization through free-radical techniques, both chain-growth and reversible addition-fragmentation chain-transfer methods. The monomer was designed to be compatible with other commercially available monomers and solvents to facilitate ease of copolymerization through free-radical polymerization techniques. The polymerization does not require perfluorinated alkyl substances or perfluorooctanoic acids or related compounds in the synthesis of the fluoropolymers.
