专利号:US-11938187-B2 优先权日:2021-06-10 标题:Methods and compositions for synthesis of two-photon cleavable phosphoramidite molecules for oligonucleotide conjugation 发明人:LO PEGGY PIK KWAN; LIU LING SUM; TAM DICK YAN 权利人:UNIV CITY HONG KONG 摘要:The syntheses of two phosphoramidite building blocks based on BNSF and BNSMB structures are disclosed. Furthermore, some common molecular intermediates have been designed and linked to the central biphenyl core of the two molecules, resulting in a versatile and cost-effective design. These compounds can be effectively introduced to DNA oligonucleotides via the well-established standard cyanoethylphosphoramidite chemistry on the nucleic acid synthesizer. Fragmentation of these BNSF- and BNSMB-functionalized DNA strands is achieved by both one-photon and two-photon photolysis of photoliable bonds of [2-(2-nitrophenyl)propoxy]carbonyl groups on BNSF and BNSMB molecules respectively, resulting in two short pieces of single-stranded DNAs. The versatile design and facile synthesis of these two-photon photocleavage phosphoramidite molecules are beneficial to synthetic chemists and photochemists for the development of new caged compounds which enables to introduce into oligonucleotides as light-triggered carriers via solid-phase synthesis for a wide range of applications in materials science, polymer, chemistry, biology and DNA nanoecthnology.

A modifier was used for synthesis of 5′-methacrylated oligonucleotides for preparation of microarrays by a co-polymerization method.
专利号:US-4609707-A 优先权日:1983-11-10 标题 :Synthesis of polymers containing integral antibodies 发明人:NOWINSKI ROBERT C; HOFFMAN ALLAN S 权利人:GENETIC SYSTEMS CORP 摘要:A method is disclosed for the de novo synthesis of antibody-containing polymers and the preparation of a class of polymerizable compounds used in the synthesis of such antibody-containing polymers. Antibody-containing polymers formed from monomer/antibody conjugates and nonderivatized polymerizable compounds can be varied in formation of the polymer to provide control of (a) molecular spacing, steric accessibility and the number of antibody molecules that are integrally incorporated into the polymer backbone, and (b) the chemical and physical structure of the polymer itself, thus enabling specific tailoring of antibody-containing polymers for particular end-use application. Also disclosed is a method for the selective removal of a compound from a solution or suspension thereof using monomer/receptor conjugates where the compound has the capacity to bind to the receptor in the conjugate. The bound compound is removed by polymerization - induced separation of the monomer/receptor--compound complex from solution.
