Synthesis and antiviral activity of 1-(2-deoxy-.beta.-D-ribofuranosyl)-5-(methylmercapto)-2-pyrimidinone
摘要:
1-(2-Deoxy-beta-D-ribofuranosyl)-5-(methylmercapto)-2-pyrimidinone (1b) was synthesized via modification of the silyl method. 1b inhibits the Herpes simplex virus type 1 (98%) and type 2 (97%) at a concentration which is nontoxic to human HeLa cells. The compound shows 50 times greater binding affinity (lower Ki) to the virus-specific thymidine kinase than to the thymidine kinase of uninfected HeLa cells.
