Method of preparing a guanosine-group compound and an intermediate thereof |
| abstract |
A glyoxal-guanosine-group compound is prepared either by reacting glyoxal-guanine with any one of ribose-1-phosphate and 2-deoxyribose-1-phosphate in the presence of purine nucleoside phosphorylase, or by reacting glyoxal-guanine with any one selected from the group consisting of uridine, 2′-deoxyuridine and thymidine, together with phosphate ion, in the presence of purine nucleoside phosphorylase and pyrimidine nucleoside phosphorylase. The glyoxal-guanosine-group compound is then decomposed by alkali, whereby a guanosine-group compound consisting of guanosine and 2′-deoxyguanosine is prepared. |
