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).

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.

专利号:US-2008300418-A1 优先权日:2004-11-08 标 题:Synthesis of Cardiolipin Analogues and Uses Thereof 发明人:AHMAD MOGHIS U; UKKALAM MURALI K; ALI SHOUKATH M; AHMAD IMRAN 权利人:AHMAD MOGHIS U; UKKALAM MURALI K; ALI SHOUKATH M; AHMAD IMRAN 摘要:The invention provides novel synthetic methodologies for preparing cardiolipin, migrated caridiolipin (1,2-positional isomer of cardiolipin) and their analogues having varying fatty acids and/or alkyl chains with varying length and degrees of saturation/unsaturation. The method comprises (a) reacting an optically pure 1,2-O-dialkyl-sn-glycerol or 1,2-O-dialkyl-sn-glycerol with one or more phosphoramidite reagent(s), wherein a phosphite triester is produced; (b) coupling the product of (a) with glycerol, wherein a protected cardiolipin is produced; and (c) deprotecting the protected cardiolipin, such that cardiolipin is prepared. The cardiolipins and analogues thereof, prepared by the present methods, can be incorporated into liposomes, which can also include active agents such as hydrophobic or hydrophilic drugs, antisense nucleotides or diagnostic agents. Such liposomes can be used to treat diseases or can be used in diagnostic and/or analytical assays.
