专利号:US-10730904-B2 优先权日:2012-11-14 标 题:Method for liquid-phase synthesis of nucleic acid 发明人:NONOGAWA MITSURU; NAGATA TOSHIAKI; SAITO HIDEKI; YASUMA TSUNEO 权利人:TAKEDA PHARMACEUTICALS CO 摘要:In this method, an oligonucleotide represented by formula (II) [wherein Y 1 , 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, R 1 , Y, Base, Z, Ar, R 2 , R 3 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.

专利号:US-2024124938-A1 优先权日:2019-10-16 标题:Visual detection of pbd induced dna crosslinks 发明人:LACHAUD CHRISTOPHE; COMBES SÉBASTIEN; ABEL SÉBASTIEN; AUDOLY GILLES; BERRADA SARA 权利人:INST NAT SANTE RECH MED; INST JEAN PAOLI & IRENE CALMETTES; AIX MARSEILLE UNIV; CENTRE NAT RECH SCIENT 摘要:The present invention relates to the field of oncology. laboratory tools and methods, and especially anti-tumor DNA crosslinking agents. Most patients with advanced solid tumors develop resistance to chemotherapy due to the ability of cancer cells to repair or tolerate sustained DNA damages. The inventors showed that the compounds according to the present invention allow the detection and visualization of alkylated DNA damages induced by PBDs without altering their DNA crosslinking ability. This enables the study of the effect and properties of PBDs. In particular, the present invention relates new derivates of PBD molecules and their synthesis. The present invention also relates to a method for visualizing DNA crosslinking: to a method for assessing the resistance of a tumor to a crosslinking agent and to a method for identifying a molecule or treatment for improving the efficiency of a crosslinking agent.
