专利号:US-12383499-B2 优先权日:2018-01-01 标题:Scale up synthesis of silicasome nanocarriers 发明人:NEL ANDRE E; MENG HUAN; LIU XIANGSHENG 权利人:UNIV CALIFORNIA 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).
专利号:US-2012177593-A1 优先权日:2009-07-20 标 题 :Synthesis of dendrimer conjugates 发明人:BAKER JR JAMES R; ZHANG YUEHUA; THOMAS THOMMEY P; DESAI ANKUR MAHESH 权利人:BAKER JR JAMES R; ZHANG YUEHUA; THOMAS THOMMEY P; DESAI ANKUR MAHESH; UNIV MICHIGAN 摘要:The present invention relates to novel methods of synthesis of therapeutic and diagnostic dendrimers. In particular, the present invention is directed to novel dendrimer conjugates, novel methods of synthesizing the same, compositions comprising the conjugates, as well as systems and methods utilizing the conjugates (e.g., in diagnostic and/or therapeutic settings (e.g., for the delivery of therapeutics, imaging, and/or targeting agents (e.g., in disease (e.g., cancer, inflammatory disease) diagnosis and/or therapy, pain therapy, etc.)). Accordingly, dendrimer conjugates of the present invention may further comprise at least two different components for targeting, imaging, sensing, and/or providing a therapeutic or diagnostic material and/or monitoring response to therapy. Furthermore, the novel synthesis methods of certain embodiments of the present invention provide significant advantages with regard to total reaction time and simplicity.
