专利号:US-2009171097-A1 优先权日:2005-11-22 标题 :Automated solid phase synthesis of pyrrole-imidazole polyamide 发明人:SUGIYAMA HIROSHI; DOHNO CHIKARA; FUKUDA NOBORU 权利人:SUGIYAMA HIROSHI; DOHNO CHIKARA; FUKUDA NOBORU 摘要:A synthesis method for pyrrole-imidazole polyamide is automated at a higher level and can produce a product with a high yield in a more stable manner. In a solid phase synthesis method, the automated synthesis of a polyimide can be promoted by using HCTU as a condensation-activator, the yield of a product can be increased by charging a monomer in a solid form, and a pyrrole-imidazole polyamide having any sequence can be synthesis by combining the synthesis method with a manual synthesis with an acid chloride.
专利号:US-12421628-B2 优先权日:2018-07-23 标题:Massively parallel enzymatic synthesis of nucleic acid strands 发明人:HORGAN ADRIAN; GODRON XAVIER; YBERT THOMAS; NICOL ROBERT 权利人:DNA SCRIPT 摘要:The invention is directed to methods for massively parallel template-free enzymatic synthesis of a plurality of different polynucleotides of predetermined sequences. In one aspect, methods of the invention employ large scale arrays of reaction sites each associated with at least one working electrode for controlling deprotection and deblocking steps at predetermined user selected sites. In another aspect, the invention provides template-free enzymatic synthesis with proofreading, wherein completed polynucleotides at predetermined reaction sites are sequenced using a sequencing by synthesis technique, particularly employing electrochemically labile blocking groups.

专利号:US-2023272006-A1 优先权日:2021-08-31 标题:Peptidomimetics and method of synthesis thereof 发明人:NEFZI ADEL 权利人:NEFZI ADEL; THE FLORIDA INTERNATIONAL UNIV BOARD OF TRUSTEES 摘要:The subject invention provides compounds, peptidomimetics, and methods of synthesis thereof. The subject invention provides the synthesis and use of guanidino acids and/or poly guanidino acids not only as vehicles for drug delivery but as toolbox for drug discovery. The peptidomimetic of the subject invention comprises oligo(guanidino acid)s or poly(guanidino acid)s with guanidines as peptide bond surrogates. The incorporation of the guanidine as amide bond surrogates offers significant differences in polarity, hydrogen bonding capability, and acid-base character.
