L. Cappellacci et al., SYNTHESIS, ANTITUMOR-ACTIVITY AND CRYSTALLOGRAPHIC STUDIES OF ANALOGSOF TIAZOFURIN, Nucleosides & nucleotides, 14(3-5), 1995, pp. 637-640
The syntheses and antitumor activity of 2-beta-D-ribofuranosylfuran-4-
carboxamide (furanfurin) and 2-beta-D-ribofuranosylthiophene-4-carboxa
mide (thiophenfurin) are reported. The X-ray structure of ethyl 2-beta
-D-ribofuranosylthiophene-4-carboxylate, precursor of thiophenfurin, i
s also presented. Only thiophenfurin showed activity as an antitumor a
gent both in vitro and in vivo.
