Synthesis of some new thioethers of 1,2,4-triazine-3-hydrazones and assays for their anticancer and anti human immune virus activities.

A number of various thioethers derived from 3-hydrazone-5,6-diphenyl-1,2,4-triazines have been synthesized and evaluated for anticancer and anti HIV activities. The structures are supported by elemental analysis, IR, UV and 1H-NMR spectral data. Most of the tested compounds displayed a significant activity against Leukemia/Lymphoma, CNS, Ovarian and Small cell lung cancer.
