Compounds useful as antiviral agents against DNA containing viruses, such as herpes group viruses, are disclosed. The compounds are selected from the group consisting of: ##STR1## and their pharmaceutically acceptable salts and solvates. Pharmaceutical compositions containing compounds represented by Formula 1.0 are disclosed. Also disclosed are methods of treating a viral infection using compounds represented by Formula 1.0. A process for making compounds of Formula 1.0 from the appropriate 3-oximino-quinolin-2,4(1H)-dione (Formula 2.5) is also disclosed. The process comprises reductively hydrolyzing an appropriate 3-oximino-quinolin-2,4(1H)-dione (Formula 2.5) in a mixture with a hydrogenation catalyst and an acidic solvent mixture.
揭示了作为抗DNA含病毒(如疱疹病毒组)的抗病毒剂的有用化合物。这些化合物选自以下组合物:##STR1##及其药学上可接受的盐和溶剂。揭示了含有代表Formula 1.0的化合物的药物组合物。还揭示了使用代表Formula 1.0的化合物治疗病毒感染的方法。还揭示了一种从适当的3-氧基亚喹啉-2,4(1H)-二酮(Formula 2.5)制备Formula 1.0化合物的过程。该过程包括在含有氢化催化剂和酸性溶剂混合物的混合物中还原水解适当的3-氧基亚喹啉-2,4(1H)-二酮(Formula 2.5)。
