Latest Patents
Alfred Stumpe holds a patent for a process for the synthesis of oligonucleotides. This invention discloses novel methods for synthesizing oligonucleotides using nucleoside phosphoramidites on solid supports. The methods involve stepwise chain assembly on supports with 5'-acyl phosphoramidites. The synthesis cycles include a front-end deprotection step, a phosphoramidite coupling step, a phosphite oxidation step, and an optional capping step. These novel methods enhance the quality of synthetic oligonucleotides by preventing the formation of deletion sequences and avoiding acidic reagents that can lead to depurination side products. The invention also includes new nucleoside phosphoramidite compositions with acyl front-end protective groups that can be cleaved with primary amines or phenolates. This invention is applicable to the synthesis of oligodeoxyribonucleotides, oligoribonucleotides, and oligonucleotides with modifications in their sugar or phosphate groups. He has 1 patent to his name.
