专利号:US-7102023-B2 优先权日:1999-11-24 标 题:Protecting groups useful in the synthesis of polysaccharides, natural products, and combinatorial libraries 发明人:BUCHWALD STEPHEN L; PLANTE OBADIAH J; SEEBERGER PETER H 权利人:MASSACHUSETTS INST TECHNOLOGY 摘要:One aspect of the present invention relates to optionally substituted halogenated benzyl halides and the like. These compounds are useful as halogenated benzyl ether-based protecting groups for a variety of functional groups. Another aspect of the present invention relates to use of said protecting groups in an orthogonal protecting group strategy for the synthesis of complex molecules that comprise a number of suitable functional groups. Another aspect of the present invention relates to saccharides bearing various arrays of protecting groups of the present invention. Another aspect of the present invention relates to a method of synthesizing an oligosaccharide or glycoconjugate, comprising the steps of: using a saccharide bearing at least one protecting group of the present invention to glycosylate a second molecule to give a product comprising said saccharide; and removing a protecting group of the present invention from said product.
专利号:US-2009221568-A1 优先权日:2005-11-04 标题:Synthesis of Inhibitors of FtsZ 发明人:SHAW JARED; URGAONKAR SAMEER; RAYCHAUDHURI DEBABRATA; LA PIERRE HENRY 权利人:SHAW JARED; URGAONKAR SAMEER; RAYCHAUDHURI DEBABRATA; LA PIERRE HENRY 摘要:FtsZ, the bacterial analog of tubulin, is a promising new target for developing new antibiotics. It has been shown that polyphenols inhibit the GTPase activity of FtsZ, thereby inhibiting Z-ring formation during mitosis. The present invention provides novel polyphenols compounds, which can be accessed by the synthesis of dichamametin and 2′″-hydroxy-5″-benzylisouvarinol-B as described herein. These novel compounds are useful in treating infections, particularly infections caused by gram-positive organisms. Methods of preparing the inventive compounds are also provided. The compounds are prepared by the benzylation of pinocembrin or chrysin core structure. Pharmaceutical compositions and method of using the compounds to treat disease are also provided. These compounds may be screened for antimicrobial activity as well as other biological activities such as anti-neoplastic, anti-inflammatory, immunosuppressive, and cytotoxic activity.
