Active Motif's CUDC-101 is a novel hybrid dual-acting histone deacetylase (HDAC) and receptor tyrosine kinase inhibitor. It is a potent HDAC inhibitor which that inhibits EGFR and HER2 (IC50 = 4.4 nM, 2.4 nM and 15.7 nM respectively). It not only blocks EGFR and HER2 but also attenuates multiple compensatory pathways such as AKT, HER3 and MET which enable tumor cells to escape the effects of conventional EGFR/HER2 inhibitors.
