专利号:US-5726301-A 优先权日:1992-04-24 标题 :CAC H-phosphonate and its use in the synthesis of oligonucleotides 发明人:REDDY M PARAMESWARA; HANNA NAEEM B; FAROOQUI FIRDOUS 权利人:BECKMAN INSTRUMENTS INC 摘要:Disclosed herein are N4 protected deoxycytidines for use in the synthesis of oligonucleotides, the protecting groups being represented by the formula: -CO-(CH2)0-9-CH3. Preferred embodiments are N4 acetyl deoxycytidines and include N4 acetyl deoxycytidine phosphoramidites and N4 acetyl deoxycytidine H-phosphonates. When used to prepare oligonucleotides the protected deoxycytidine compounds provide high quality oligonucleotide products with little side product from cleavage and deprotection reactions carried out with alkyl amine compounds.

The device for making the modified nucleosides, modified nucleotides and modified nucleic acids (e.g., mRNA) disclosed herein may be mobile devices comprising at least one sample block for insertion of one or more sample vessels, a device base with electronic control units for the sample block, a voltage supply, and one or more reagent(s) for the synthesis of at least one nucleic acid.
专利号:US-5428148-A 优先权日:1992-04-24 标 题 :N4 - acylated cytidinyl compounds useful in oligonucleotide synthesis 发明人:REDDY PARAMESWARA M; HANNA NAEEM B 权利人:BECKMAN INSTRUMENTS INC 摘要:Disclosed herein are protecting groups for exocyclic amino groups of the bases adenine, guanine and cytosine for use in the synthesis of oligonucleotides, the protecting groups being represented by the formula: -CO- (CH2)0-9-CH3. In a particularly preferred embodiment, the base cytosine is protected with acetyl (-CO-CH3), and the oligonucleotide incorporating said protected cytosine is subjected to a cleavage/deprotection reagent comprising at least one straight chain alkylamine having from 1 to about 10 carbon atoms.

专利号:US-2025207163-A1 优先权日:2022-03-25 标 题:Methods and apparatus for synthesizing nucleic acids 发明人:HOPKINS PATRYCJA A; SHAHSAVARI SHAHIEN; BEGOYAN VAGARSHAK; NJUMA OLIVE J; DEBENHAM HOLLY S; EFCAVITCH J WILLIAM; ALBIZATI KIM F 权利人:MOLECULAR ASSEMBLIES INC 摘要:Methods for the synthesis of polynucleotides using polymerases nucleotide analogs with labile terminator groups that allow stepwise addition of nucleotides are described. These nucleotide analogs may have a modification on 3′, 2′, or 3′-2′-bridged hydroxyl groups or on nucleobase moieties and can be used in the synthesis of natural or modified polynucleotides suitable for use in biological systems. The labile terminator groups are removed under mild conditions or by enzymes. They are accepted as substrates by polymerases. The synthesis may be carried out on a surface.
