Abstract: The invention relates to new bis-triazole 2,4,6-triarylpyridines compounds and their use in the field of oncology, in particular in the prevention and/or treatment of cancer disease. The inventors have observed that the new bis-triazole 2,4,6-triarylpyridines were able to induce cancer cells death either as a standalone or, synergistically, in combination with a lysosomotropic agent, such as chloroquine. The compounds were active against a variety of cancer cells such as HeLa (cervical cancer cell), A549 (lung carcinoma), and PDX-2 or PDX-3 (lung adenocarcinoma). The invention also relates to compositions and methods for prevention and/or treatment of cancer diseases using the new bis-triazole 2,4,6-triarylpyridines compounds.
