专利号:US-2002037834-A1 优先权日:2000-09-08 标题 :Compositions and methods for enhanced sensitivity and specificity of nucleic acid synthesis 发明人:ASTATKE MEKBIB; GEBEYEHU GULILAT 权利人:INVITROGEN CORP 摘要:The present invention relates to cationic and polycationic compositions and methods for enhancing synthesis of nucleic acid molecules. In a preferred aspect, the invention relates to inhibition or control of nucleic acid synthesis, sequencing or amplification. Specifically, the present invention discloses cationic and polycationic molecules, compounds, and compositions having affinity for double-stranded and/or single-stranded nucleic acid molecules and/or single-stranded/double-stranded nucleic acid complexes (e.g., primer/template complexes, double-stranded templates, single-stranded templates or single-stranded primers) for use in such enhanced synthesis. The cationic and polycationic molecules, compounds, and compositions of the invention are capable of inhibiting nonspecific nucleic acid synthesis at ambient temperature. Thus, in a preferred aspect, the invention relates to “hot startâ€? synthesis of nucleic acid molecules. Accordingly, the invention prevents non-specific nucleic acid synthesis at low temperatures, for example during reaction set up. The invention also relates to kits for synthesizing, amplifying, reverse transcribing or sequencing nucleic acid molecules comprising one or more of the cationic and polycationic molecules, compounds, and compositions of the invention. The invention also relates to compositions prepared for carrying out the methods of the invention and to compositions made after or during such methods. The invention also generally relates to compositions useful for inhibiting or preventing degradation of various nucleic acid molcules.
专利号:US-7109377-B2 优先权日:1996-10-16 标 题:Synthesis of combinatorial libraries of compounds reminiscent of natural products 发明人:SCHREIBER STUART L; SHAIR MATTHEW D; TAN DEREK S; FOLEY MICHAEL A; STOCKWELL BRENT R 权利人:HARVARD COLLEGE 摘要:The present invention provides complex compounds reminiscent of natural products and libraries thereof, as well as methods for their production. The inventive compounds and libraries of compounds are reminiscent of natural products in that they contain one or more stereocenters, and a high density and diversity of functionality. In general, the inventive libraries are synthesized from diversifiable scaffold structures, which are synthesized from readily available or easily synthesizable template structures. In certain embodiments, the inventive compounds and libraries are generated from diversifiable scaffolds synthesized from a shikimic acid based epoxyol template. In other embodiments, the inventive compounds and libraries are generated from diversifiable scaffolds synthesized from the pyridine-based template isonicotinamide. The present invention also provides a novel ortho-nitrobenzyl photolinker and a method for its synthesis. Furthermore, the present invention provides methods and kits for determining one or more biological activities of members of the inventive libraries. Additionally, the present invention provides pharmaceutical compositions containing one or more library members.
专利号:US-2024286903-A1 优先权日:2023-02-24 标 题 :Crystalline Sp-Sp2 Hybridized Carbon Allotropes through Dynamic Covalent Synthesis 发明人:ZHANG WEI; HU YIMING 权利人:UNIV COLORADO REGENTS 摘要:Disclosed is a method for the synthesis of crystalline -graphyne which exhibits an ABC stacking pattern in the crystal structure. Alkyne metathesis is used to reversibly cleave and reform bonds between sp-hybridized carbon atoms to create an sp and sp 2 -hybridized carbon network. An exemplary method includes providing a first hexa-alkynyl substituted benzene co-monomer (e.g., HPB) and a second hexa-alkynyl substituted co-monomer (e.g., HHEB), and undergoing an alkyne metathesis reaction in the presence of a catalyst. During the reaction, small short chain alkyne byproducts can be removed, to drive the reaction toward the formation of the -graphyne polymer product, while the larger alkyne byproducts can facilitate the self-correction process that will minimize the structural defects in the resulting -graphyne.

The method includes forming a diastereoselective epoxide compound of formula (I) from a chiral alpha amino aldehyde and halomethyllithium as an organometallic methylene-adding reagent. In formula (I) R<1> is selected from alkyl, aryl, cycloalkyl, cycloalkylalkyl and arylalkyl, which are optionally substituted with a group selected from alkyl, halogen, NO2, OR<9> or SR<9>, where R<9> represents hydrogen or alkyl; and P<1> and P<2> independently are selected from amine protecting groups, including but not limited to, arylalkyl, substituted arylalkyl, cycloalkenylalkyl and substituted cycloalkenylalkyl, allyl, substituted allyl, acyl, alkoxycarbonyl, aralkoxycarbonyl and silyl.
