    Nucleosides and nucleotides containing 8-aza-7,9-dideazaxanthine

  • Original language description

    The described preparation of 8-aza-7,9-dideazaxanthine from 1,3-dibenzyluracil and TosMIC was improved by using AlCl3 for final debenzylation. Treatment of 6-dibromomethyl- 5-formyluracil with benzyl-, 4-methoxybenzyl-, and 1-adamantylamine gave the corresponding 8-alkyl-8-aza-7,9-dideazaxanthines. N1- and N8-(8-phosphonooctyl)-8-aza-7,9-dideazaxanthines were prepared and found as inhibitors of thymidine phosphorylase (V79 cells, human placenta, Escherichia coli). IC50 values ranged at 3?27 .mu.M.

    8-Aza-7,9-dideazaxanthin byl připraven pomocí TosMIC a 1,3-dibenzyluracilu. Postup byl vylepšen užitím AlCl3 pro finální debenzylaci. 8-Alkyl-8-aza-7,9-dideazaxanthiny byly připraveny reakcí 6-dibromomethyl-5-formyluracilu s benzyl-, 4 methoxybenzyl-, a1 adamantylaminem. Bylo zjištěno že N1- a N8-(8-fosfonooktyl)-8-aza-7,9-dideazaxanthin jsou učinnými inhibitory thymidin fosforylasy (V79 buňky, lidská placenta, Escherichia coli). Hodnoty IC50 3?27 .mu.M.
