  Synthesis and antitumor activity of 7- and 9-(6'-deoxy-.alpha.-L-talofuranosyl)-hypoxanthine and 9-(6'-deoxy-.alpha.-L-talofuranosyl)-6-thiopurine

  摘要：

  Reaction of 6-deoxy-2,3,5-tris-O-(p-nitrobenzoyl)-L-talofuranosyl bromide (1) with the trimethylsilyl derivative of hypoxanthine, followed by removal of blocking groups, afforded 9- (6) and 7-(6'-deoxy-alpha-L-talofuranosyl)hypoxanthine (7). A study of the published optical rotations and circular dichroic (CD) spectra of pentofuranosylpurines and of (6'-deoxy-beta-D-allo- and -alpha-L-talofuranosyl)purines prepared here suggests that the sign of rotation and the sign of the longer wavelength Cotton effect is determined solely by the configuration of C-1' and its position of attachment to the purine ring. For C-1' R nucleosides, the sign is negative for N-9-linked purine nucleosides and positive for the N-7-linked isomers, and vice versa for C-1'S purine nucleosides. Reaction of 1 with the trimethylsilyl derivative of 6-chloropurine afforded 4, which upon treatment with thiourea and deblocking yielded 9-(6'-deoxy-alpha-L-talofuranosyl)-6-thiopurine (8). Unlike the previously prepared 7-(6'-deoxy-beta-D-allofuranosyl) hypoxanthine which strongly inhibited purine nucleoside phosphorylase, compounds 6-8 did not inhibit this enzyme. Compound 8 significantly inhibited the growth of L1210 tumor cells in vitro and in vivo.
