标题:Materials and methods for the photodirected synthesis of oligonucleotide arrays
发明人：SERAFINOWSKI PAWEL JERZY; GARLAND PETER BRYAN
权利人:CANCER RES INST ROYAL
摘要:Materials and methods for photodirected synthesis of oligonucleotide arrays on a solid substrate by photodirected synthesis are disclosed which employ a film formed from (i) a photoacid generator that on photolysis generates acid that is capable of directly removing the protecting group of the linker molecules or oligonucleotides and (ii) a polymer substantially lacking electronegative heteroatoms that are capable of hydrogen bonding with photogenerated acid. Methods of synthesizing an oligomer arrays are also described that use a film that restricts diffusion of reactants and products on the substrate during synthesis of the array and which includes a precursor of a deprotecting reagent. The method involves removing one or more of the non-required products of the deprotection reaction from the reactive array elements at which they are produced during the reaction, in order to displace the deprotection reaction towards completion.

权利人:POSTECH RES & BUSINESS DEV FOUND
摘要:Disclosed are ultrafast flow synthesis of functionalized sulfonyl fluorides and subsequent SuFEx connections via lithiated chemistry. In detail, a method of synthesizing an ortho-functionalized benzenesulfonyl fluoride derivative, the method comprises (a) reacting a benzenesulfonyl fluoride derivative represented by structural formula 1 with an organolithium represented by structural formula 2, thus synthesizing an intermediate represented by structural formula 3 in reaction scheme 1 and (b) reacting the intermediate with an electrophile, thus synthesizing a compound represented by structural formula 4 or a compound represented by structural formula 4′. The present disclosure enables the synthesis of several functionalized sulfonyl fluorides within a few seconds under mild temperature conditions in addition to the chemistry of Sulfonyl Fluoride Exchange (SuFEx), which is a next-generation click chemistry, so that sulfonyl fluoride, the main reactant of the SuFEx reaction, can be efficiently secured.

发明人：DERAS MICHAEL; PLEISS JEFFREY A; SCARINGE STEPHEN
权利人:DHARMACON INC
摘要:The present invention comprises methods and compositions for splint-assisted enzymatic synthesis of polyribonucleotides using an RNA polymerizing enzyme. The invention provides ligating ribonucleotides comprising ligating a donor RNA molecule to an acceptor RNA molecule in the presence of RNA ligase and a splint, wherein the donor RNA molecule is comprised of at least one nucleotide and a ligation linker moiety, the acceptor RNA molecule is comprised of at least one nucleotide and a ligation linker moiety and the splint is comprised of a polyribonucleotide. The invention also provides splints for use in splint-assisted enzymatic synthesis using an RNA polymerizing enzyme.

标 题:Diversity-oriented synthesis of N,N,O-trisubstituted hydroxylamines from alcohols and amines by N—O bond formation
发明人：CRICH DAVID; HETTIKANKANAMALAGE ASIRI; HILL JARVIS
权利人:UNIV GEORGIA
摘要:In one aspect, the disclosure relates to a method for the direct synthesis of complex N,N,O-trisubstituted hydroxylamines by N—O bond formation. In another aspect, the method can successfully be employed using a wide variety of commercially available alcohols and secondary amines and enables the construction of large fragment-based libraries of trisubstituted hydroxylamines for drug discovery purposes. Also disclosed are N,N,O-trisubstituted hydroxylamines having low basicity, high stability at ambient temperatures, and an inherent lack of reactivity towards acetylating and sulfonylating enzymes that confer mutagenicity on less-substituted hydroxylamines.

权利人:UNIV NOTRE DAME DU LAC
摘要:Embodiments herein relate to histone deacetylaces (HDACs) and HDAC inhibitors, such as trichostatin A (TSA) and TSA analogues. Embodiments provide simple methods of synthesizing TSA and TSA analogues. These methods provide routes of synthesis of TSA and TSA analogues that enable the production of the HDAC inhibitors at lower cost and in greater quantities than previously were available.
