title: Crystal structure, antitumour and antimetastatic activities of disubstituted fused 1,2,4-triazinones.
abstract: Molecular structure of 3,8-disubstituted 7,8-dihydroimidazo[2,1-c][1,2,4]triazin-4(6H)-ones (8-14) was confirmed by X-ray crystallography of 14. All the compounds were evaluated for their antitumour and antimetastatic activities in vitro. Furthermore, their cytotoxicities towards human normal cell line-HSF cells were established, allowing us to point out some structure-activity relationships. Among them, imidazotriazinone 12, revealing remarkable dose-dependent viability decreases in human myeloma RPMI 8226 cells, was found to be completely non-toxic towards normal HSF cells. In addition, heterobicycles 8-12 were proved to exhibit significant antimetastatic potentials in the motility assay.
