The present invention relates to aryl triazole derivatives of Formula I having antitumoural activity through, as one possible biological target, the molecular chaperone heat shock protein 90 (Hsp90) inhibition. The invention includes the use of such compounds in medicine, in relation to cancer disease as well as other diseases where an inhibition of Hsp90 is responsive, and the pharmaceutical composition containing such compounds.

A set of compounds, previously selected as potent Hsp90 alpha inhibitors, has been studied on a panel of human parasites. 5-Aryl-3,4-isoxazolediamide derivatives (1) were active against two protozoa, Trypanosoma brucei rhodesiense and Plasmodium falciparum, with a good tolerability toward cytotoxicity on non-malignant L6 rat myoblast cell line, unlike the 1,5-diaryl,4-carboxamides-1,2,3-triazole derivatives (2) which, while showing a single-digit nM range activity against the same protozoa, were also highly cytotoxic on L6 cells. In a subsequent in vivo study, two isoxazolediamide derivatives, 1a and 1b, were very efficacious on the sleeping sickness-causing agent with a clear parasitaemia during treatment. These data, however, showed that not all protozoa are sensitive to Hsp90 inhibitors, as well as not all Hsp90 inhibitors are equally active on parasites. (C) 2014 Elsevier Ltd. All rights reserved.
