A. Tontini et al., SYNTHESIS OF 1-(ISOXAZOL-3-YL)TRIAZENE DERIVATIVES - ANTIMETASTATIC ACTIVITY OF 3,3-DIMETHYL-1-(5-METHYLISOXAZOL-3-YL)TRIAZENE, European journal of medicinal chemistry, 31(9), 1996, pp. 735-740
The synthesis of some 3,3-dialkyl-1-(isoxazol-3-yl)triazenes is report
ed, together with preliminary biological tests on 3,3-dimethyl-1-(5-me
thylisoxazol-3-yl)triazene 3a. This compound exerts a selective antime
tastatic action in mice bearing Lewis lung carcinoma, reducing the wei
ght but not the number of metastases. Some unfavorable properties in t
he toxicological profile of 3a have discouraged further investigation
of this class of compounds.
