Synthesis and Biological Evaluation of 2-(2-deoxy-d-erythro-pent-1-enofuranosyl)pyridine C-nucleosides
1991
2-(2-Deoxy-D-erythro-pent-1-enofuranosyl)pyridine and its methyl analogues have been prepared by treatment of the corresponding 2',3'-O-isopropylidene-D-ribofuranosyl derivatives with several bases such as sodium amide, tert.BuOK, EtONa, lithium tetramethylpiperidide (LTMP) and phenyl lithium (PhLi). PhLi and tert.BuOK gave the best results. The products thus obtained showed cytostatic activity against human tumor cell lines, in particular MT-4, a human T-lymphocyte cell line. No antiviral activity was noted at subtoxic concentrations.
