Stichwörter: | 2'-DEOXYTUBERCIDIN; Chemistry; Chemistry, Organic; Chemistry, Physical; NUCLEIC-ACIDS; OLIGONUCLEOTIDES | Erscheinungsdatum: | 1996 | Herausgeber: | ROYAL SOC CHEMISTRY | Journal: | JOURNAL OF THE CHEMICAL SOCIETY-PERKIN TRANSACTIONS 2 | Ausgabe: | 11 | Startseite: | 2373 | Seitenende: | 2376 | Zusammenfassung: | The crystal structure of 7-iodo-2'-deoxytubercidin 2 has been determined and was compared with those of 2'-deoxytubercidin 3 and 2'-deoxyadenosine 4, The bulky 7-iodo substituent lies 13.2 pm below and the nitrogen of the 6-amino group 5.5 pm above the 7-deazapurine plane, The puckering of compound 2 is (3).E while compound 3 shows a T-2'(3') sugar pucker. The conformation in aqueous solution, determined by H-1 NMR spectroscopy, is only slightly different, showing a (2')E conformation, The glycosylic bond torsion angle is anti in all cases. |
