摘要:A new seedless synthesis of anisotropic nanoscale gold nanoflower (AuNF) particles uses bidentate thiolate ligands to protect the nanoparticle surface and a combination of reagents (for example, ligand, ascorbic acid, and hydroxide) to synthesis AuNF with controlled size and anisotropic properties. Compared to prior art gold nanospheres, AuNF produced approximately a 15-fold improvement in a drug delivery assay.

摘要:Provided is a method for enzymatic synthesis of capped mRNA in one tube. In the method, the step of purifying mRNA after IVT is omitted, and a capped product having a higher capping efficiency and fewer by-products is obtained. The method provided for enzymatic synthesis of capped mRNA is simple, convenient and short in terms of the process, and is rapid and efficient, so that the production process of a capped mRNA product is simplified, and a production cost is reduced, which is conducive to industrial production.

标题 :Synthesis of tetracyclines and analogues thereof

摘要:The tetracycline class of antibiotics has played a major role in the treatment of infectious diseases for the past 50 years. However, the increased use of the tetracyclines in human and veterinary medicine has led to resistance among many organisms previously susceptible to tetracycline antibiotics. The modular synthesis of tetracyclines and tetracycline analogs described provides an efficient and enantioselective route to a variety of tetracycline analogs and polycyclines previously inaccessible via earlier tetracycline syntheses and semi-synthetic methods. These analogs may be used as anti-microbial agents or anti-proliferative agents in the treatment of diseases of humans or other animals.

标 题:Synthesis of purine locked nucleic acid analogues
发明人：KOCH TROELS; JENSEN FLEMMING REISSIG
权利人:SANTARIS PHARMA AS
摘要:The present invention relates to a new method for the synthesis of purine LNA (Locked Nucleic Acid) analogues which provides a higher overall yield. The method comprising a regioselective 9-N purine glycosylation reaction followed by a one-pot nucleophilic aromatic substitution reaction of the 6-substituent in the purine ring and simultaneous nucleophile-induced intramolecular ring closure of the C-branched carbohydrate to form novel purine LNA analogues. The novel strategy is illustrated by the synthesis of the novel compound (1S,3R,4R,7S)-7-benzyloxy-1-methanesulfonylmethyl-3-(guanin-9-yl)-2,5-dioxabicyclo[2.2.1]heptane which is easily converted into (1S,3R,4R,7S)-7-hydroxy-1-hydroxymethyl-3-((2-N-isobutyrylguanin-9-yl)-2,5-dioxabicyclo[2.2.1]heptane after isobutyryl protection of the 2-amino purine group and subsequent substitution of 1-methanesulfonyl with benzoate, debenzoylation and debenzylation.

摘要:The present invention relates to processes for synthesis of isobornyl (meth)acrylate by reacting camphene with (meth)acrylic acid in the presence of sulfuric acid and at least one compound having inhibiting action. Aqueous sulfuric acid with an acid concentration in the range of 65 to 85 wt % is used. Isobornyl (meth)acrylate can advantageously be distilled from a mixture containing sulfuric acid in the presence of 2,6-di-tert-butyl-alpha-(dialkylamino)-p-cresol.
