专利号:US-9556140-B2 优先权日:2013-01-26 标 题 :Approach for synthesis of catechins 发明人:DUGAR SUNDEEP; MAHAJAN DINESH; RAI KUMAR SANTOSH; TRIPATHI VINAYAK; PATIL ISHWAR RAKESH 权利人:SPHAERA PHARMA PRIVATE LTD 摘要:A process for synthesis of enatiomerically pure or enatiomerically enriched or racemic mixture of (+ and/or −) epicatechin and its intermediates, comprising the steps of: (i) obtaining penta-protected quercetin; (ii) reducing the penta-protected quercetin obtained from step (i); (iii) optionally deprotecting the compound of step (ii); (iv) reducing the compound obtained from step (ii) or step (iii) in the presence of a chiral/achiral reducing agent to obtain a chiral intermediate; (v) deprotecting and/or hydrogenation of the chiral intermediate obtained from step (iv) to obtain (−)-epicatechin; (vi) optionally simultaneously deprotecting and by drogenation of the compound obtained from step (ii) to obtain racemic epicatechin.
专利号:US-6455680-B1 优先权日:2000-12-21 标 题 :Methods utilizing aryl thioimines in synthesis of erythromycin derivatives 发明人:LUKIN KIRILL A 权利人:ABBOTT LAB 摘要:An efficient deoximation technique for use in synthesis of erythromycin derivatives, involving aryl thioimine intermediates is disclosed. The aryl thioimine intermediates can be utilized in a method for protecting a ketone of a ketone-containing erythromycin derivative as a thioimine; a method for deoximating an oxime-containing erythromycin derivative, or a method for preparing a 6-O-alkyl erythromycin derivative. Presently preferred erythromycin derivatives have a C-9 oxime or a C-9 ketone.
专利号:US-9428482-B2 优先权日:2011-01-27 标 题 :Process for synthesis of polyphenols 发明人:DUGAR SUNDEEP; MAHAJAN DINESH; PANTELIS PETER GIANNOUSIS; SINGH VIJAY; KAPOOR KAMAL KISHORE 权利人:DUGAR SUNDEEP; MAHAJAN DINESH; PANTELIS PETER GIANNOUSIS; SINGH VIJAY; KAPOOR KAMAL KISHORE; SPHAERA PHARMA PTE LTD 摘要:The present invention provides synthetic processes for preparing racemic and/or optically pure epicatechin, epigallocatechin and related polyphenols as such or as their variously functionalized derivatives. A principle objective of the disclosure is to provide a new and useful method of synthesis to obtain polyphenols in isomerically pure and/or racemic forms.
专利号:US-2024400552-A1 优先权日:2016-11-11 标题 :Heterocyclic modulators of lipid synthesis 发明人:BUCKLEY DOUGLAS I; DUKE GREGORY; WAGMAN ALLAN S; EVANCHIK MARC; MCDOWELL ROBERT S 权利人:SAGIMET BIOSCIENCES INC 摘要:Compounds that are fatty acid synthesis modulators are provided. The compounds may be used to treat disorders characterized by dysregulation of the fatty acid synthase function by modulating the function and/or the fatty acid synthase pathway. Methods are provided for treating such disorders including viral infections, such as hepatitis C infection, cancer and metabolic disorders, such as non-alcoholic steatohepatitis (NASH).
