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).

The invention also provides improved methods for the synthesis of Compound 1, new pharmaceutical compositions comprising Compound 1, and new uses of Compound 1.
专利号:US-2022143183-A1 优先权日:2019-02-23 标题:Photoswitchable protacs and synthesis and uses thereof 发明人:TRAUNER DIRK; REYNDERS MARTIN; MATSUURA BRYAN; BEROUTI MARLEEN; PAGANO MICHELE 权利人:UNIV NEW YORK 摘要:Provided are compounds, which may be referred to as PHOTACs (photoswitchable proteolysis targeting chimeras), and compositions, kits, and methods of making and using PHOTACs. PHOTACs have one or more E3 ligase ligand(s), one or more photoswitchable group(s), optionally, one or more linker(s), and one or more ligand(s) for a target protein. PHOTACs may be suitable for use in methods to treat diseases, such as, for example, cancer. PHOTACs may also be suitable for use in methods to induce selective degradation of a target protein.
专利号:US-2022400732-A1 优先权日:2019-03-21 标题:Anti-fructose therapy for colorectal and small intestine cancers 发明人:GONCALVES MARCUS; CANTLEY LEWIS C; YUN JIHYE 权利人:UNIV CORNELL 摘要:As described herein ingestion of high amounts of sugar, especially fructose, can increase the growth of intestinal tumors. Such cancer growth can be inhibited or prevented by limiting the amounts of sugar and amino acids ingested, by inhibiting ketohexokinase (KHK), fructose transport (via GLUT5), fatty acid synthesis (via FASN), phosphoinositide 3-kinases (PI3K), or by limiting amounts of sugar and amino acids ingested while also receiving KHK inhibitors, GLUT5 inhibitors, FASN inhibitors, PI3K inhibitors, or a combination of such inhibitors.
