  A Practical Synthesis ofN1-Methyl-2′-deoxy-ψ-uridine (ψ-Thymidine) and Its Incorporation into G-Rich Triple Helix Forming Oligonucleotides

  摘要：

  A convenient synthesis of N1-methyl-2'-deoxy-psi-uridine (psi-thymidine, psi T, 7a) has been accomplished in good yield. The structural conformation of 7a was derived by 2D NMR and 1D NOE experiments. The nucleoside 7a has been incorporated into G-rich tripler forming oligonucleotides (TFOs) by solid-support, phosphoramidite method. The tripler forming capabilities of the modified TFOs (S4, S5 and S6) containing psi T has been evaluated in antiparallel motif with a target duplex (duplex-31) 5'd(CTGAGACCGGGAAGGAGGAAGGGCCAGTGAC)3'-5d(GACTCTGGCCCTTCCTCCTTCCCGGTCACTG)3' (D1) at pH 7.6. The tripler formation of modified homopyrimidine-oligomers (S1, S2 and S3) has also been studied in parallel motif with a duplex-10 (A(10):T-10) at pH 7.0.

  An efficient and facile syntheses of 5'-O-(4,4'-dimethoxytrityl)-3'-[2-cyanoethyl bis(1-methylethyl)]phosphoramidites of 2-N-methyl-2'-deoxy-psi-isocytidine (h), 2-N-methyl-2'-deoxy-alpha-psi-isocytidine (13 ), 2-N-methyl-2'-O-allyl-psi-isocytidine (11), 1,3-dimethyl-2'-deoxy-psi-uridine (4) and N1-methyl-2'-O-allyl-psi-uridine (19) have been accomplished in good overall yields. The pyrimidine-pyrimidine transformation reaction was found to be useful for the preparation of 2-N-methyl-2'-O-allyl-psi-isocytidine (10). The utility of these novel phosphoramidites is demonstrated by their incorporation into oligonucleotides via solid-support, oligonucleotide methodology.

  1-Methyl-5-(3-azido-2,3-dideoxy-beta-D-erythro-pentofuranosyl)uracil (C-AZT), a C-nucleoside isostere of the potent anti-AIDS nucleoside 3'-azido-3'-deoxythymidine (AZT), was synthesized. 1-Methyl-2'-deoxy-5'-O-tritylpseudouridine (2a) was oxidized with CrO3/pyridine/Ac2O complex to 1-methyl-5-(5-O-trityl-beta-D-glycero-pentofuranos-3-ulosyl) uracil (12a), which was selectively reduced to 1-methyl-5-(5-O-trityl-beta-D-threo-pentofuranosyl)uracil (13a). Mesylation of 13a to 14a followed by nucleophilic displacement of the mesyloxy group with azide afforded 3'-azido-2',3'-dideoxy-5'-O-trityl-1-methylpseudoridine (15a), which was detritylated to C-AZT. In a similar manner, 1-methyl-5-(2-deoxy-2-fluoro-beta-D-arabinofuranosyl)uracil (C-FMAU, a potent antiherpetic nucleoside) was converted into the 3'-azido analogue (3'-azido-C-FMAU). Both C-AZT and 3'-azido-C-FMAU, however, did not exhibit any significant inhibitory activity against HIV in H9 cells.
