Heterocyclic nucleoside analogues: Design and synthesis of antiviral, modified nucleosides containing isoxazole heterocycles

Abstract

We have designed and synthesized novel antiviral nucleoside analogues, which consist of isoxazole rings as modified sugars and nucleobases (thymine, uracil, and 5-fluorouracil) with a methylene linker between them. These compounds represent a new class of modified nucleoside analogues and some of them show potent antiviral activities against Polio virus (Coxsackie B type 3 and Vesicular Stomatitis).
