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-10391067-B2 优先权日:2015-08-18 标题:Prevention and treatment of neurodegenerative diseases through autophagy activity mediated by a synthetic ligand or arginylated BIP binding to the P62 ZZ domain 发明人:KWON YONG TAE; KIM BO YEON; CHA HYUNJOO; YOO YOUNG DONG; Yu ji-eun 权利人:SEOUL NAT UNIV R&DB FOUNDATION; KOREA RES INST BIOSCIENCE & BIOTECHNOLOGY; AUTOTAC BIO 摘要:The pharmacokinetics and key technologies of the present invention are summarized in FIG. 1. Particularly, malignant misfolded proteins such as mutant huntingtin and alpha-synuclein are coagulated and grow into oligomeric coagulum ({circle around (1)}, {circle around (2)}, fibrillar coagulum ({circle around (3)}) and eventually inclusion body ({circle around (4)}). Young neurons produce a large amount of Nt-Arg through N-terminal arginylation ({circle around (5)}) of vesicle chaperones such as BiP secreted into the cytoplasm, and then arginylated BiP (R-BiP) is secreted binds to the misfolded proteins ({circle around (6)}). As a ligand, the Nt-Arg of R-BiP binds to the p62 ZZ domain ({circle around (7)}), and the normally inactivated closed form of p62 is changed to an open form, leading to structural activation ({circle around (8)}). As a result, PB1 and LC3-binding domains are exposed. The PB1 domain induces oligomerization ({circle around (9)}), leading to the concentration as a p62 body ({circle around (10)}) that is a coagulum capable of being degraded by autophagy. Then, p62 binds to LC3, which is protruding from the autopagosomal membranes, leading to the completion of autophagy targeting ({circle around (11)}) and lysosomal proteolysis. Since autophagy proteolysis including steps ({circle around (5)})-({circle around (11)}) is strong in young neurons, cytotoxic protein coagulums ({circle around (1)}-{circle around (5)}) do not accumulate. However in aged neurons, autophagy proteolysis including steps {circle around (5)}-{circle around (11)} is weakened, and protein coagulums ({circle around (1)}-{circle around (5)}) accumulate and become cytotoxic. In this invention, p62 is intentionally activated ({circle around (12)}, {circle around (13)}) by using low mass ligands of the p62 ZZ domain to effectively remove huntingtin and alpha-synuclein protein coagulums. Particularly, in step {circle around (12)}, p62 ligated with a ligand accelerates the oligomerization of p62-R-BiP-misfolded protein ({circle around (9)}) and the formation of autophagy coagulum ({circle around (10)}). In step ({circle around (13)}), the ligand-p62 conjugate acts as an autophagy activator ({circle around (14)}) to induce the synthesis of LC3 and the conversion of LC3-I into LC3-II in order to accelerate the formation of autophagosomes ({circle around (15)}).

The surfactant is selected from polyoxyethylene octadecyl amine, n-decanoyl-N-methylglucamide, sodium cholate, n-octyl-β-D-thioglucopyranoside, n-nonyl-β-D-thiomaltopyranoside, sucrose monocholate, sucrose monocaprate, and sucrose monolaurate. The chondroitin sugar chain has all the following properties: a weight average molecular weight: 50,000 or more when measured by gel filtration chromatography; it is completely degraded to disaccharides with chondroitinase ABC; and when the sugar chain is decomposed with chondroitinase ABC and the decomposed products are subjected to a disaccharide analysis, substantially all of them correspond to an unsaturated disaccharide unit of chondroitin.

Such copolymers meet the security and costs requirements to be used as solid polymers electrolytes (SPE). They are promising alternatives to standard liquid electrolytes in alkaline metal-ion batteries because of their improved security and inflammability properties. The copolymers described are either polyvinylsulfonates or acrylate vinylsulfonate block-copolymers. Preferred acrylate monomers are methacrylates and preferred vinylsulfonates are styrene sulfonates. The copolymer is prepared by radical polymerization of the vinyl sulfonate and the cross-linker and optionally the acrylate, in particular radical photopolymerization using a functionalized bis(acyl)phosphane oxide (BAPO) as photoinitiator. Also described is the use of such copolymer as solid polymer electrolyte in a lithium ion battery.
