Patent number: 10730904Abstract: In this method, an oligonucleotide represented by formula (II) [wherein Y1, Q, Base, r and r? are each as defined in claim 1] is prepared by using, as a synthesis unit, a novel nucleoside monomer compound represented by formula (I) [wherein X, R1, Y, Base, Z, Ar, R2, R3 and n are each as defined in claim 1]. The novel nucleoside monomer compound is a nucleoside, the base moiety of which is substituted with an aromatic-hydrocarbon-ring-carbonyl or -thiocarbonyl group having at least one hydrophobic group. The method can dispense with column-chromatographic purification in every reaction, and enables base elongation not only in the 3?-direction but also in the 5?-direction, thus attaining efficient liquid-phase mass synthesis of an oligonucleotide.Type: GrantFiled: January 4, 2019Date of Patent: August 4, 2020Assignee: TAKEDA PHARMACEUTICAL COMPANY LIMITEDInventors: Mitsuru Nonogawa, Toshiaki Nagata, Hideki Saito, Tsuneo Yasuma
