چکیده

7-Hydroxyguanine, an antitumor purine-analog, reacted with ribose (or deoxyribose)-1-phosphate in the presence of purine nucleoside phosphorylase. We prepared 7-hydroxyguanine riboside and deoxyriboside using purine nucleoside phosphorylase from bovine spleen. Each nucleoside exhibits antitumor activity against mouse leukemia L1210 cells. The therapeutic effect of 7-hydroxyguanine deoxyriboside is superior to those of 7-hydroxyguanine and 7-hydroxyguanine riboside.

Preparation of new 7-hydroxyguanine derivatives and their biological activities.

We prepared new 7-hydroxyguanine derivatives, 7-hydroxyguanosine 5'-monophosphate and N2-tetrahydropyranyl-7-hydroxyguanine, and compared biological activities of 7-hydroxyguanine derivatives including nucleosides acquired previously. 7-Hydroxyguanine and its nucleotide inhibited the focus formation of Rous sarcoma virus. Antitumor activities of these derivatives against mouse leukemia L1210 we...

ATTEMPTED SYNTHESIS OF 5' - DEOXY - 5' - PHOSPHONO - ISOCYTIDINE SYNTHESIS OF PHOSPHONIC ACID DERIVATIVES OF ACYCLO - NUCLEOSIDES. PREPARATION OF 1- ?- D- ARABINOFURANOSYL PYRIMIDINES

The synthesis of 5' - deoxynucleoside 5' - phosphonates which contains a 5' - CP bond in place of the 5' -COP bond of the naturally occuring nucleotides is described. The preparation of phosphonate derivatives of acyclo - nucleosides and a simple method for the conversion of 1-? -D-ribofuranosyl pyrimidines to the corresponding 1-? -D-arabinofuranosyl pyrimidines are also explained

Ethynyl side chain hydration during synthesis and workup of "clickable" oligonucleotides: bypassing acetyl group formation by triisopropylsilyl protection.

Clickable oligonucleotides with ethynyl residues in the 5-position of pyrimidines ((eth)dC and (eth)dU) or the 7-position of 7-deazaguanine ((eth)c(7)G(d)) are hydrated during solid-phase oligonucleotide synthesis and workup conditions. The side products were identified as acetyl derivatives by MALDI-TOF mass spectra of oligonucleotides and by detection of modified nucleosides after enzymatic p...

Deoxyribosyl compounds in animal tissues.

Several types of deoxyribosyl compounds have been found in the acidsoluble fraction of normal and malignant tissues (l-8). In 1955 Potter and Schlesinger (1) reported the isolation of deoxynucleoside mono-, di-, and triphosphates from extracts of calf thymus. More recently LePage (7) reported the isolation of deoxyadenosine triphosphate from a tumor. Schneider (2), using a microbiological assay...

Mutagenicities of 8-hydroxyguanine and 2-hydroxyadenine produced by reactive oxygen species.

Oligodeoxyribonucleotides containing 8-hydroxyguanine and 2-hydroxyadenine, purine lesions produced in cells by reactive oxygen species, were synthesized and inserted into vector DNAs to introduce each lesion at a predetermined site. The manipulated DNAs were transfected into living cells, and the mutants induced by each DNA lesion were collected and analyzed. In addition, the mutations induced...
