Pu, Yu-Ji,Yuan, Hui,Yang, Ming,He, Bin,Gu, Zhong-Wei
, p. 917 - 920 (2013)
Inorganic polyhedral oligomeric silsesquioxane (POSS) was used as the core for the synthesis of poly(l-lysine) peptide dendrimer via copper-catalyzed azide-alkyne click chemistry. The inorganic/organic composite dendrimer was characterized by MS, 1/

Paragraph 0019; 0020, (2019/08/02)
The invention belongs to the field, and particularly relates to chemical preparation and application. When the problem group is subjected to chemical synthesis research on the skeleton by guaiguazulene and piperidine acid as raw materials, the derivative trans - 1, 2 - (1, 4 - diazulyl) ethene ene derivative of guaiabazulene is found. H1N1 Influenza virus testing, indicating that the compound is level, 25 mm in vitro antiviral activity superior to that of positive drug ribavirin. In vivo activity tests prove, the compound not only can inhibit the pneumonia symptoms, but also can reduce the titer, and the survival rate. , The survival rate, 5 mg/kg/day the lung virus titer . of virus-infected mice can be remarkably improved when stomach tube-like dosages are used for gastric lavage. In general, the activity of the compound is comparable, and the activity of the compound is comparable to that of oseltamivir. The utility model can be used for preparing antiviral drugs. The invention opens up a new way for deep research and development of new antiviral drugs, which is a new approach. (by machine translation)

Paragraph 0023, (2018/12/03)
The invention relates to a method for preparing an amino-acid ester and belongs to the field of organic compound synthesis. The method comprises the following steps: by taking sulfur trioxide as a catalyst and a water bounding agent, catalyzing amino acid to react with an alcohol so as to prepare sulfate of the amino-acid ester, concentrating the reaction system, removing a reaction solvent, dissolving with water, and further neutralizing with ammonia water, thereby obtaining the amino-acid ester. The method for preparing the amino-acid ester, which is provided by the technical scheme of the invention, has the advantages of being gentle in reaction process, high in yield, high in purity, simple to operate and low in cost. By adopting the method for preparing the amino-acid ester, centrifugal mother liquid condensed water can be subjected to biochemical treatment directly, a solid byproduct of high-purity ammonium sulfate can be generated, the byproduct can be used as a chemical fertilizer, the reaction process is green and pollution-free, and the environment can be protected.
