Redox Homeostasis Modulators
Through a rational design programme, our team has identified key pharmacophores around a chemical class targeting the modulation of redox homeostasis. Experimental data show that these compounds are potent inducers of oxidative stress, perturb the cell cycle, induce apoptosis and inhibit HIF-1a signal transduction and the expression of VEGF. Anti-tumour activity has been demonstrated in xenograft models against a number of common solid tumours, including colon, breast, renal and pancreatic.
Our lead candidate, PMX 2058, is a water soluble pro-drug of the active moiety, PMX 290. It is scheduled to enter regulatory toxicology studies in the second half of 2009.
Our experimental data suggest that these compounds are able to modulate redox homeostasis in several ways and the wide-ranging anti-tumour activity of these compounds may be due to multiple mechanisms of action, including:
