Cyclic monophosphate prodrugs of base-modified 2′-C-methyl ribonucleosides as potent inhibitors of hepatitis C virus RNA replication
摘要:
A new series of heterobase-modified 2 '-C-methyl ribonucleosides was synthesized and tested as inhibitors of hepatitis C virus (HCV) RNA replication. The nucleosides showed a weak inhibitory activity in a HCV replicon system (EC50 = 92 mu M) and did not exhibit any cytotoxicity (CC50 > 300 mu M). Cyclic monophosphate (cMP) prodrugs of the same nucleosides were synthesized and also tested in the HCV replicon system. Prodrugs exhibited strong potency (EC50 = 0-008)mu M) without significant cytotoxicity (CC50 > 50 mu M). (C) 2007 Elsevier Ltd. All rights reserved.
