标题:Dynamic and combinatorial synthesis of polymerase primers
发明人：BENNER STEVEN ALBERT
权利人:BENNER STEVEN ALBERT
摘要:This invention relates to the field of nucleic acid chemistry, more specifically to compositions of matter that are nucleic acid analogs, and processes that use them. Still more specifically, these compositions comprise two fragments of DNA-like molecules, each having one or more ends modified to carry a reactive group, where the reactive group on one fragment can form a transient covalent bond with the reactive group on the other under conditions of dynamic equilibrium to form a composite, where the composite can then bind to a target oligonucleotide, such as a DNA or RNA molecule. Most specifically, once the transient covalent bond forms, the composite serves as a primer for a template-directed polymerization using a DNA polymerase, an RNA polymerase, or a reverse transcriptase. Once incorporated, the epimerization causes the base pair to be destabilized, the duplex containing the epimerized nucleoside to likewise be destabilized, and the double strand to then disassociate. This leaves the template available to template the synthesis of another complementary oligonucleotide containing the epimerizing base.

摘要:The invention provides a method for making a combinatorial library of cyclic compounds, such as Holliday junction-trapping compounds, comprising the steps of (a) obtaining a plurality of trimers according to the generic structure X 1- X 2- X 3 , wherein X 1 , X 2 and X 3 can be independently any naturally or nonnaturally occurring amino acids or peptidomimetics thereof; (b) optionally coupling a spacer S to the trimer at either end; (c) cyclizing two trimers or trimer-spacer conjugates in a head-to-tail orientation; thereby obtaining a combinatorial library of compounds, wherein the library does not include an unmodifed or naturally occurring Holliday Junction-trapping compounds. The invention additionally provides methods macrocyclic compounds that are synergimycin derivatives.

摘要:The synthesis of capped/tagged RNA, methods of use and kits providing same are contemplated. Tagged RNA permits isolation of RNA transcripts in vitro. The ability to isolate and purify capped RNA results in improved transcription and translation and provides a tool for identifying RNA-protein interactions. Such capped RNA finds use in therapeutic applications, diagnosis and prognosis and in the treatment of cancers and HIV.

摘要:2-Pyridones are conveniently synthesized from 2,4-pentadienoic acids by formation of the acid azide, decomposition of the azide into an isocyanate and the simultaneous cyclization of the isocyanate into the pyridone. The pyridones are readily converted into known pyridines.

摘要:The present invention relates to the technical field of fine organic chemicals, and provides a continuous synthesis method for a disperse yellow dye. Continuous tubular reaction technology is used. A continuous tubular reactor provided by the present invention has a small volume, a large specific surface area, and a large heat transfer area per unit volume. The continuous tubular reactor can promptly transfer reaction heat by means of heat exchange and can ensure safety while accelerating the feeding speed. The continuous tubular reaction provided by the present invention precisely controls a raw material ratio, so that a feeding ratio of main raw materials is close to a theoretical value. In addition, by means of introducing an automatic control system, the chemical reaction can be carried out at a raw material ratio that strictly follows an optimal set value. The mass transfer and heat transfer effect of the continuous reactor is relatively good. Following the improvement to the mass transfer and heat transfer effect, the temperature control is more precise, and the generation of by-products is reduced.
