Recently, beta-L-nucleoside analogues have emerged as a new class of sugar modified nucleosides with potential antiviral and/or antitumoral activity. As a part of our ongoing research on this topic, we decided to synthesize 5-CF3-beta-L-dUrd (7), the hitherto unknown L-enantiomer of Trifluridine, an antiherpetic drug approved by FDA but only used in topical applications due to concomitant cytotoxicity. 5-CF3-beta-L-dUrd (7) as well as some other related L-nucleoside derivatives were stereospecifically prepared and tested in vitro against viral (HSV-1 and HSV-2) and human thymidine kinases (TK).

Abstract
Recently, beta-L-nucleoside analogues have emerged as a new class of sugar modified nucleosides with potential antiviral and/or antitumoral activity. As a part of our ongoing research on this topic, we decided to synthesize 5-CF3-beta-L-dUrd (7), the hitherto unknown L-enantiomer of Trifluridine, an antiherpetic drug approved by FDA but only used in topical applications due to concomitant cytotoxicity. 5-CF3-beta-L-dUrd (7) as well as some other related L-nucleoside derivatives were stereospecifically prepared and tested in vitro against viral (HSV-1 and HSV-2) and human thymidine kinases (TK).File in questo prodotto:
