Final Report Abstract

We developed the second generation TriPPPro-prodrugs for the intracellular delivery of NTP derivatives with efficient metabolic bypass and superior antiviral properties. TriPPPro-compounds bearing two lipophilic groups at the γ-phosphate or γ-phosphonate group, respectively, are designed to enable a successful crossing of biological barriers. The second generation TriPPPro-prodrugs (26, 30, 34, and 35) comprising a non-cleavable moiety in addition to a biodegradable prodrug moiety at the γ-phosphate or γ-phosphonate group, respectively, revealed a higher potential for use in antiviral chemotherapies than the first generation TriPPPro-prodrugs 8,9 bearing two biodegradable masking groups. We have convincingly shown that the development of this TriPPPro-strategy can make a significant contribution to the development of improved antiviral agents based on nucleoside analogues.
