Abstract: Methods for the treatment of cancers or tumors in mammals are disclosed which uses 2-(2,4-difluorophenyl)-1,3-bis(1H-1,2,4-triazol-1-yl)propan-2-ol or derivatives thereof. A chemotherapeutic agent and/or a potentiator may be used in combination with 2-(2,4-difluorophenyl)-1,3-bis(1H-1,2,4-triazol-1-yl)propan-2-ol or derivatives thereof. 2-(2,4-Difluorophenyl)-1,3-bis(1H-1,2,4-triazol-1-yl)propan-2-ol or derivatives thereof may also be used to treat viral infections, either alone, in combination with other anti-viral agents, or in combination with a potentiator.
