专利号:US-10730904-B2 优先权日:2012-11-14 标 题:Method for liquid-phase synthesis of nucleic acid 发明人:NONOGAWA MITSURU; NAGATA TOSHIAKI; SAITO HIDEKI; YASUMA TSUNEO 权利人:TAKEDA PHARMACEUTICALS CO 摘要:In this method, an oligonucleotide represented by formula (II) [wherein Y 1 , Q, Base, r and r′ are each as defined in claim 1 ] is prepared by using, as a synthesis unit, a novel nucleoside monomer compound represented by formula (I) [wherein X, R 1 , Y, Base, Z, Ar, R 2 , R 3 and n are each as defined in claim 1 ]. The novel nucleoside monomer compound is a nucleoside, the base moiety of which is substituted with an aromatic-hydrocarbon-ring-carbonyl or -thiocarbonyl group having at least one hydrophobic group. The method can dispense with column-chromatographic purification in every reaction, and enables base elongation not only in the 3′-direction but also in the 5′-direction, thus attaining efficient liquid-phase mass synthesis of an oligonucleotide.
专利号:WO-2022227554-A1 优先权日:2021-04-30 标题 :Larotaxel-fatty alcohol small molecule prodrug and construction of self-assembling nanoparticle thereof 发明人:LUO CONG; WANG YONGJUN; YANG JINCHENG; MA HONGDA; SUN JIN; HE ZHONGGUI; FENG YAO; MA ZHINING 权利人:SUZHOU YUTAI PHARMACEUTICAL TECH CO LTD 摘要:The synthesis of a larotaxel-fatty alcohol small molecule prodrug with a tumor reduction response characteristic and the construction of a self-assembling nanoparticle, and the use thereof in the preparation of a drug delivery system. Provided is a larotaxel-stearyl alcohol small molecule prodrug, which is prepared into a larotaxel-fatty alcohol prodrug nanoparticle. The larotaxel-fatty alcohol prodrug nanoparticle can be a non-PEGylated larotaxel-fatty alcohol prodrug nanoparticle, a PEG-modified larotaxel-fatty alcohol prodrug nanoparticle, a drug-loaded larotaxel-fatty alcohol prodrug nanoparticle, and an active targeting larotaxel-fatty alcohol prodrug nanoparticle. The larotaxel-fatty alcohol prodrug has few synthetic steps, a simple process, reduced synthesis costs, a high yield and easy purification, and the nanoparticle formed by the self-assembly of the larotaxel-fatty alcohol small molecule prodrug has an ultra-small particle size, which reduces the toxicity and side effects while improving the curative effect of larotaxel.
专利号:US-2009318592-A1 优先权日:2005-10-11 标 题 :Process for the Synthesis of Amine Ethers 发明人:FREY MARKUS; BROENNIMANN VALERIE 权利人:CIBA GEIGY CORP 摘要:The present invention relates to novel processes for the preparation of a sterically hindered amine ether by reacting a corresponding sterically hindered amine oxide with a ketone or an aldehyde with at least one reactive H in the presence of a peroxydisulphate. Products obtained by this process may be hydrogenated. The compounds made by these processes are particularly effective in the stabilization of polymer compositions against harmful effects of light, oxygen and/or heat and as flame-retardants for polymers.
专利号:US-2023175032-A1 优先权日:2020-05-13 标 题 :Efficient synthesis of omega-glycosides and alkyl glycosides 发明人:SOETAERT WIM; ROELANTS SOPHIE; STEVENS CHRISTIAN; DELBEKE ELISABETH; LUYTEN GOEDELE; PALA MELIKE; REMMERY JELLE 权利人:AMPHISTAR; UNIV GENT 摘要:The present invention relates to the field of production of novel biosurfactants. More specifically, the present invention relates to the efficient generation of short chained on-glycosides with less than 10%, preferably less than 1%, ω-1 glycosides using a fungal strain such as the yeast Starmerella bombicola having a dysfunctional CYP52M1 cytochrome P450 monooxygenase and a dysfunctional FAO1 fatty alcohol oxidase to produce high amounts of so-called unsaturated (symmetrical) α,ω-bola glycosides free from contaminating α,ω-1 bola glycosides, and subjecting said unsaturated (symmetrical) α,ω-bola glycosides to conditions inducing the breaking of the present double bond(s) such as for example through ozonolysis performed in water. More specifically, the present invention discloses the generation of (acetylated) C9:0 ω-sophoroside aldehydes, C9:0 ω-glucoside aldehydes, C9:0 ω-glucolipids, C9:0 ω-sophorolipids, C9:0 ω-sophoroside alcohols and C9:0 ω-glucoside alcohols and their further derivatives. The present invention also discloses methods to produce alkyl sophorosides in increased ratios.
