Publikováno v: Journal of Medicinal Chemistry. 45:3138-3142
Novel 2-amino-6-arylthio-9-[2-(phosphonomethoxy)ethyl]purine bis(2,2,2-trifluoroethyl) esters were synthesized and evaluated for antihepatitis B virus (HBV) activity in vitro using HB611, HuH-6 cell line, stably transfected with the HBV genome. Among

Some Aspects on Acyclonucleoside Synthesis
Autor: Kouichi Sdciya, H Takashima, M Ubasawa
Publikováno v: Nucleosides and Nucleotides. 17:2241-2247
An acyclonucleoside synthesis was investigated on the regioselective introduction of an acyclochain. We found that iodotrimethylsilane catalyzed the reaction of acyclochain introduction as well as its migration from S2 to N1 of 2-thiothymine and from

Functional Word in Protein. VI. Recognition
Autor: Shigero Ikeda, Yukio Kiho, Christopher Palmer, Guru Bhandari, Aiko Ubasawa
Publikováno v: Proceedings of the Japan Academy, Series B. 73:74-78
Interaction between trypsin and its substrate, NDV-F, is investigated by two approaches, in which the natural sequence and the polar/non-polar sequence are used respectively. In the first approach that we call“stepwise recognition”, addition of t

Functional Word in a Protein. IV. Alphabet
Autor: Yukio Kiho, Aiko Ubasawa, Yasunori Okabe, Tsuruji Iwai
Publikováno v: Proceedings of the Japan Academy, Series B. 72:185-190
A unique nucleotide sequence that consists of aligned second bases of colon triplets in the cDNA sequence of trypsin is designed to identify the active sites on the DEV model. Compared with the amino acid sequence that was exploited before, the assig

Autor: E. De Clercq, Kouichi Sekiya, M Ubasawa, Masanori Baba, H Walther, H Takashima, Peter P. Mager
Publikováno v: European Journal of Medicinal Chemistry. 31:701-712
Summary The dioxypyrimidine ring of 5,6-substituted 1-[(2-hydroxyethoxy)methyl]uracils is an extended ‘partial π system’ with ring distortion. PM3-MM+ geometry optimization suggested a lipophilic ‘butterfly-like’ orientation which was also f
