Jay Amin Hydroxamic Acid (JAHA; N8-ferrocenylN1-hydroxy-octanediamide) is a ferrocene-containing analogue of the histone deacetylase inhibitor (HDACi) suberoylanilide hydroxamic acid (SAHA). JAHA’s cytotoxic activity on MDA-MB231 triple negative breast cancer (TNBC) cells at 72 h has been previously demonstrated with an IC50 of 8.45 M. JAHA’s lethal effect was found linked to perturbations of cell cycle, mitochondrial activity, signal transduction and autophagy mechanisms. In order to glean novel insights on how MDA-MB231 breast cancer cells respond to the cytotoxic effect induced by JAHA, and to compare the biological effect with the related compound SAHA, we have employed a combination o…
