摘要:Provided is a method for fully liquid-phase synthesis of a GRnH nonapeptide amide analog, which belongs to the technical field of medicine synthesis. The method comprises respectively synthesizing a 'Trp-Ser-Tyr' fragment, an 'R-Leu' fragment, a 'Pyr-His' fragment and 'Arg-Pro-Hunan T', wherein, R = D-Ala (alarelin), D-Leu (leuprorelin), D-Trp (deslorelin) and D-His (histrelin), and obtaining the GRnH nonapeptide amide analog with high yield and high purity by means of a '3 +2 +2 +2' fragment condensation method. The synthesis method is environmentally friendly, mild, and free of any highly toxic and poisonable reagents. The cost is greatly reduced and the synthesis method is very suitable for large-scale production.

标题:Scale up synthesis of silicasome nanocarriers

摘要:In order to facilitate the approval and commercialization of silicasome drug delivery systems (e.g. irinotecan silicasomes) it is necessary to scale up synthesis of the drug-loaded silicasomes. In this regard, it was discovered that the synthesis protocols used for laboratory synthesis of drug-loaded silicasomes (e.g., 500 mg/batch) do not scale to large scale silicasome production, because the resulting products were too heterogeneous for use as pharmaceuticals. Accordingly, new methods are provided herein that effectively afford the large-scale production of mesoporous silica nanoparticles (MSNPs) and lipid bilayer coated MSNPs (silicasomes).
