title: Synthesis and cytostatic properties of 5-substituted derivatives of 3-methylisoxazolo[5,4-d]1,2,3-triazine-4-ones and 3-methyl-5-triazene 4-isoxazolecarboxylic acid ethyl esters.
abstract: Six new 5-substituted derivatives of 3-methyl-isoxazolo[5,4-d]1,2,3-triazine-4-one and 3-methyl-5-triazene-4-isoxazolecarboxylic acid ethyl ester have been synthesized from 5-amino-3-methylisoxazole-4-carboxylic acid amides, and ethyl ester. They were examined for cytostatic activity in comparison with Dacarbazine. The 3-methyl-5-(4-chlorophenyl)isoxazolo[5,4-d]1,2,3-triazine-4-one showed better activity than Dacarbazine.
