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-9365532-B1 优先权日:2011-02-14 标题:Synthesis, composition and use of novel therapeutic and cosmetic Schiff base products formed by reaction of a carbonyl containing moeity with a transimination nucleophilic catalyst and the use of transimination nucleophilic catalysts to increase the rate at which carbonyl containing therapeutic and cosmetic actives form Schiff base products with biological amines 发明人:ISAACMAN STEVEN 权利人:ISAACMAN STEVEN; NANOMETICS LLC 摘要:The present invention relates to the synthesis, composition and use of novel moieties formed by reacting a transimination nucleophilic catalyst, molecular or polymeric, with carbonyl-containing therapeutic or cosmetic moieties. The resultant Schiff base product is highly reactive towards transimination with a biological amine. The catalyst and carbonyl-containing moiety can be molecular or polymeric, and the resultant chemical and physical properties of the Schiff base products can be engineered by appropriate selection of said catalyst. The present invention also relates to the synthesis, composition and use of novel moieties that are used as actives in sunless tanning preparations. The present invention also relates to the use of transimination nucleophilic catalysts to increase the rate at which a carbonyl-containing moiety reacts with a biological amine. The present invention also relates to the use of transimination nucleophilic catalysts to increase the rate and efficacy of commercial sunless tanning preparations. Improvements on stability and efficacy of said preparations are disclosed. While the invention has been described in terms of its preferred embodiments, those skilled in the art will recognize that the invention can be practiced with modification within the spirit and scope of the appended claims. Accordingly, the present invention should not be limited to the embodiments as described above, but should further include all modifications and equivalents thereof within the spirit and scope of the description provided herein.

参考标题:Total Synthesis Of The 5-Ht3 Receptor Antagonist Palonosetron 作者:Bruce A. Kowalczyk,Charles A. Dvorak |发布日期:1996.7 摘要:A Short And Efficient Synthetic Route To The 5-Ht3 Receptor Antagonists 1 And 2 (Palonosetron) Was Developed. The Novel Adjustment Of The Oxidation States At The Necessary Centers Of Imide 7 Was Accomplished By Hydrogenation, Selective Sodium Borohydride Reduction, And Dehydration To Yield 1. The Sodium Borohydride Reduction Of Imide 8 Was Selective For The C-3 Carbonyl Versus The C-1 Carbonyl Next To The Aromatic Ring To Give The Hydroxy Compound 9. It Was Essential To Keep The Sodium Borohydride Reduction Free Of Oxygen, Or Diols 10A And 10B Were Formed As Significant Byproducts.
