摘要:The invention herein disclosed provides for methods for the synthesis of polymers from monomers. In particular the method provides for the synthesis of polynucleotides from mononucleotides in the absence of catalytic enzymes. The method comprises providing an aqueous solution having a plurality of phospholipid molecules and monomer molecules; subjecting the aqueous solution to fluctuating temperature conditions; subjecting the aqueous solution to fluctuating cycles of drying and hydrating conditions; subjecting the aqueous solution to fluctuating [H + ] conditions; the fluctuating conditions thereby allowing formation of a chemical bond between at least two monomers to create a polymer. The invention is of particular use in the fields of molecular biology, structural biology, cell biology, molecular switches, molecular circuits, and molecular computational devices, and the manufacture thereof.

摘要:In some embodiments, the present disclosure relates to new phosphoramidite compositions, that have Silyl-containing carbonate or thiocarbonate or ether as 5′-hydroxyl protecting groups useful of the synthesis of DNA, and in particular for the synthesis of long sequences of DNA (e.g., >50 mer). In some embodiments, there are provided methods for simultaneous oxidation of the internucleoside phosphate triester linkages and removal of the 5′-hydroxyl-protecting group, making this process a new 2-step DNA synthesis, that involves the use of peroxyanions in combination with fluoride anions.

标题 :Oligonucleotide synthesis using periodate salts
发明人：SKRZYPCZYNSKI ZBIGNIEV
权利人:THIRD WAVE TECH INC
摘要:The present invention relates generally to nucleic acid chemistry and to the chemical synthesis of oligonucleotides. More particularly, the invention relates to improved methods for synthesizing oligonucleotides wherein periodate salts are used (e.g., in organic solvents) as an oxidation reagent in oligonucleotide synthesis (e.g., for automated phosphoramidite synthesis of oligonucleotides). The invention finds utility in the fields of biochemistry, molecular biology, and pharmacology, and in medical diagnostic and screening technologies.

标 题:Non-enzymatic large scale synthesis of RNA
发明人：KANAVARIOTI ANASTASSIA; DEAMER DAVID W; MONNARD PIERRE-ALAIN M; BERNASCONI CLAUDE F
摘要:This invention pertains to the development of methods that accomplish efficient, non-enzymatic, nucleic acid-directed (e.g. RNA-directed) nucleic acid (e.g. RNA) synthesis. In certain embodiments the methods provide conditions that favor oligouridylate synthesis with excellent yield and, at least, up to 30% regioselectivity favoring the RNA linkage. The methods preferably involve contacting, in the presence of lead ions (Pb 2+ ) and/or tin ions (Sn 2+ ) and, optionally, magnesium ions (Mg 2+ ), a template nucleic acid with a nucleotide derivatized with an imidazolide.
