Potential antineoplastics I: substituted 3,5-dioxo-and 3-thioxo-5-oxo-2,3,4,5-tetrahydro-1,2,4-triazines.
The synthesis of some 6-substituted 3,5-dioxo- and 3-thioxo-5-oxo-2,3,4,5-tetrahydro-1,2,4-triazines for possible antineoplastic activity is reported. The assigned structures were substantiated by IR, NMR, and mass spectral studies of representative members of the series. Four compounds were tested against P-388 lymphocytic leukemia and were inactive.
