New basic mesoporous silica catalyst obtained by ammonia grafting

Autor: Y, Inaki, Y, Kajita, H, Yoshida, K, Ito, T, Hattori

Publikováno v: Chemical communications (Cambridge, England). (22)

NH3-treated mesoporous silica (FSM-16) contains SiNH2 sites which exhibit basic catalytic activity for Knoevenagel condensation; SiNH2 and SiOH pair sites formed at lower NH3-treatment temperatures exhibit higher turnover frequencies (TFs) in compari

Isopoly-L-ornithine derivative as nucleic acid model

Autor: Y, Inaki, N, Tohnai, K, Miyabayashi, M, Miyata

Publikováno v: Nucleic acids symposium series. (37)

Isopoly-L-ornithine derivatives of thymine, and thymidine were found to hardly interact with poly A. Conformational studies of the oligomers with CD and NMR revealed that stable intramolecular hydrogen bonding was formed between the thymine base and

Specific interaction between 5'-aminonucleosides and borates and influence of borates on nucleoside conformations

Autor: T, Wada, N, Minamimoto, Y, Inaki, Y, Inoue

Publikováno v: Nucleic acids symposium series. (37)

The unique conformation and orientational change of 5'-amino-5'-deoxyuridine in Kolthoff's buffer is discussed. From CD and NOE spectra, anomalous syn orientation of Urd-5'-NH2 might be caused by specific interaction between borates and Urd-5'-NH2, w

Synthesis and properties of oligo-omega-amino acids derivatives containing nucleosides

Autor: T, Wada, N, Minamimoto, K, Okada, K, Miyabayashi, Y, Inaki, M, Miyata

Publikováno v: Nucleic acids symposium series. (34)

Nucleic acid analogs, that consist of oligo-omega-amino acids as main chains were synthesized. At first, hydroxyl group of deoxy and ribonucleic acid was converted into amino or carboxylic acid group. Then, amino acid derivatives containing aminonucl

Transfection of fluorescent probed antisense compounds: L-Cysteine derivatives of nucleic acid bases

Autor: S, Kitaoka, Y, Inaki, H, Maruoka, N, Tohnai, T, Hatae, T, Tanabe

Publikováno v: Nucleic Acids Symposium Series. 1:135-136

Antisense with L-cysteine derivative (CAS) can recognize DNA and forms the complementary duplex with DNA. So the properties of CAS in vitro and in vivo were examined in this study. CAS was resistant to proteinase K and stabilized RNA against RNase HI

Synthesis and interaction studies of watersoluble nucleic acid analogs containing serine as a spacer

Autor: T, Wada, N, Masumi, E, Mochizuki, Y, Inaki, K, Takemoto

Publikováno v: Nucleic acids symposium series. (27)

Watersoluble nucleic acid analogs containing L- or D-serine as a spacer were synthesized. Thymine was used as nucleic acid bases of these analogs. The base contents of these analogs were 93-94%. These analogs were found to form stable polymer complex

Immobilization of nucleoside on silica gel and specific separation of oligonucleotides

Autor: Y, Inaki, K, Matsukawa, H, Kawano, W, Hong, T, Wada, E, Mochizuki, K, Takemoto

Publikováno v: Nucleic acids symposium series. (27)

Deoxyadenosine was immobilized on silica gel, in order to use as HPLC resins for selective separation of oligonucleotides. The longest retention time was observed for the complementary pd(T)4, and increased with decrease of temperature. This fact sug
