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.

摘要:The present invention relates to methods of stimulating collagen synthesis and of smoothing or removing wrinkles, which comprise administering an effective amount of a benzoic acid derivative of formula (1) or a salt thereof, wherein X is -O- or -N(R4)- (R4 is H or the like), R1 is a C¿4-25?-alkyl or C4-25-alkenyl group, R?2¿ is H, OH, or a C¿1-6?-alkoxyl or C1-6-alkanoyloxy group, and R?3 is -OR5¿ or -N(R?6)R7 (R5? is H, or a C1-25-alkyl or C1-25-alkenyl group), and R?6 and R7¿ are individually H, or a C¿1-3?-alkyl or C1-3-alkenyl group, and use of this compound for agents for stimulating synthesis of collagen, and smoothing or removing wrinkles. This compound (1) stimulates collagen synthesis in human dermal fibroblasts and consequently smooths or removes wrinkles caused by aging and/or photoaging.

标题 :Optically active cobalt (II) complexes and method for the preparation of optically active alcohols
发明人:MUKAIYAMA TERUAKI; YOROZU KIYOTAKA; NAGATA TAKUSHI; YAMADA TORU; SUGI KIYOAKI
权利人:MITSUI PETROCHEMICAL IND
摘要:The invention provides a method for preparing an optically active alcohol comprising the step of reacting a ketone compound with a hydride reagent in the presence of an optically active metal compound. The resulting optically active alcohols are useful as intermediates for the synthesis of physiologically active compounds such as drugs and pesticides, functional materials such as liquid crystals, and raw materials for synthesis in fine chemistry. A novel optically active cobalt (II) complex useful as a catalyst is also provided.

标题:Preparation of cis—olefins
发明人:SATO FUMIE; MIYAJI KATSUAKI; AMANO TAKEHIRO
权利人:NISSAN CHEMICAL IND LTD; SATO FUMIE
摘要:A cis-olefin of the formula: R 1 —CHâ•?CH—R 2 is prepared by reducing an alkyne of the formula: R 1 —C≡C—R 2 with formic acid in the presence of a palladium catalyst. R 1 and R 2 are independently selected from the group consisting of a hydrogen atom, ester group, substituted silyl group, carboxyl group, cyano group, aliphatic C1-C20 hydrocarbon group, and phenyl group. The cis-olefin which is a useful intermediate for the synthesis of fine chemicals is selectively produced in high yields.
