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.

标题 :Synthesis of 3,4-bis(4-amino-1,2,5-oxadiazol-3-yl)-1,2,5-oxadiazole-n-oxide using 4-amino-3-bromocarbohydroxymoyl-1,2,5-oxadiazole

摘要:Embodiments of this disclosure describe the synthesis of 4-amino-3 bromocarbohydroxymoyl-1,2,5-oxadiazole from a precursor solution in methanol. The synthesis uses 4-amino-3-aminocarbohydroxymoyl-1,2,5-oxadiazole as the starting material. The procedure involves the sequential treatment of the starting material in methanol with hydrobromic acid, cuprous bromide, and sodium nitrite. This treatment results in the precipitation of a new chemical entity, the bromo-oxime 4-amino-3-bromocarbohydroxymoyl-1,2,5-oxadiazole. Upon obtaining the bromo-oxime derivative, the method further facilitates the production of 3,4-bis(4-amino-1,2,5-oxadiazol-3-yl)-1,2,5-oxadiazole-N-oxide (furoxan derivative) through dimerization in a biphasic reaction medium consisting of ethyl acetate and water, with potassium carbonate serving as a key reactant. This innovative method offers a streamlined approach, enabling the direct use of the intermediate oxadiazole derivative without the need for additional purification, leading to the desired furoxan derivative. This synthesis method stands out for its efficiency, high-purity yield, and fewer steps, offering potential applications in various chemical industries.
