This study presents a new potential HDAC6 selective inhibitor designed and synthesized: QTX125 [3-(3-furyl)-N-{4-[(hydroxyamino)carbonyl]benzyl}-5-(4-hydroxyphenyl)-1H-pyrrole-2-carboxamide].Results show that the QTX125 compound obtained is a new HDAC6-specific inhibitor that inhibits cell-growth inhibition and causes programmed cell death in association with increased levels of acetylated α-tubulin, its most recognizable target.The antitumoral effect is particularly evident in mantle cell lymphoma models, both in culture and in vivo, surpassing the efficacy of currently available HDAC6 inhibitors.
