Synthesis and anti human immune virus activity of some new fluorine containing substituted -3-thioxo-1,2,4-triazin-5-ones.

Some new fluorine containing substituted 3-thioxo-1,2,4-triazin-5-ones (2-17) have been synthesized and evaluated for in vitro anti human immune virus (HIV) activity. Most of the new compounds displayed a lethal activity, while compounds 2, 6, 7, 10, 11 and 14 displayed a significant antiviral activity. The structures are supported by elemental analysis, IR, UV and 1H-NMR spectral data.
