We have synthesized a series of 4H,6H-[1,2,5]oxadiazolo[3,4-d]pyrimidine-5,7-dione 1-oxide nucleoside and their anti-vesicular stomatitis virus (VSV) activities in Wish cell were also investigated in vitro. It was found that most compounds showed obvious anti-VSV activities and compound 9 with ribofuranoside improved the anti-VSV activity by approximately 10 times and 18 times compared to didanosine (DDI) and acyclovir, respectively. A quantitative structure-activity relationship (QSAR) study of these compounds as well as previous reported oxadiazolo[3,4-d]pyrimidine nucleoside derivatives indicated that compounds with high activity should have small values of log P(o/w), vsurf-G and a large log S value. These findings and results provide a base for further investigations.

The previously unknown 9-aminotheophylline and 1-methyl-9-aminoxanthine were synthesized from 3-methyl-5-amino-6-hydrazinouracil.In the case of 1-methyl-9-aminoxanthine an x-ray diffraction study of an N-amino derivative of an NH heterocycle was made for the first time.
