标 题 :Process for the synthesis of oligonucleotides

摘要:The present invention discloses novel methods for the synthesis of oligonucleotides with nucleoside phosphoramidites on solid supports. The methods comprise the stepwise chain assembly of oligonucleotides on supports with 5′-acyl phosphoramidites. The synthesis cycles consist of a front end deprotection step which is conducted with a solution of a primary amine or a phenolate, a phosphoramidite coupling step with a 5′-acyl nucleoside phosphoramidite in the presence of an activator, a phosphite oxidation step and an optional capping step. The novel methods improve the quality of synthetic oligonucleotides due to the irreversibility of the front end deprotection step, which prevents the formation of deletion sequences, and due to the avoidance of acidic reagents in the synthesis cycles, which prevent the formation of depurination side products. The invention further discloses novel nucleoside phosphoramidite compositions wherein the phosphoramidites carry acyl front end protective groups which are cleavable with primary amines or phenolates. The invention is applicable to the synthesis of oligodeoxyribonucleotides, oligoribonucleotides and oligonucleotides with modifications in their sugar or phosphate groups.

标题:Methods and compositions for synthesis of two-photon cleavable phosphoramidite molecules for oligonucleotide conjugation

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.
