Condensed pyrimidine nucleoside analogs as anti -viral agents

摘要

3-(2',3'-dideoxy-ribo-&bgr;-L-furanosyl)[2,3-d]pyrimidin-2(3H)-one derivatives comprising 6-substitutents on the base moiety are shown to have anti-viral properties, particularly with respect to vaccinia and measles. The compounds have unnatural L ribose stereochemistry.
