Synthesis and Cytostatic Activity of 4-Substituted Derivatives of Isoxazolyltriazenes

4-(3,3-Alkyltriazeno)-5-benzoylisoxazole-3-carboxamides hydrochloride 6a-h and 7-benzoyl-3,4-dihydroisoxazolo[4,3-d]-[1,2,3]-triazyne-4-one 10 have been synthesized from 4-diazo-5-benzoylisoxazole-3-carboxamide chloride 5. Some from the triazenes were examined for cytostatic activity in comparison with Dacarbazine.
