Imofinostat
Based on 1 Customer Validation
Imofinostat (ABT-301; MPT0E028) is an orally active and selective HDAC inhibitor with IC50s of 53.0 nM, 106.2 nM, 29.5 nM for HDAC1, HDAC2 and HDAC6, respectively. Imofinostat has a weak inhibitory effect on HDAC8 (IC50 of 2.5 μM), but no inhibitory effect on HDAC4 (IC50>10 μM). Imofinostat reduces the viability of B-cell lymphomas by inducing apoptosis and possesses potent direct Akt targeting ability and reduces Akt phosphorylation in B-cell lymphoma. Imofinostat has a broad-spectrum antitumor activity, including colorectal cancer, B-cell lymphoma, non-small cell lung carcinoma (NSCLC), and pancreatic cancer, while also showing therapeutic potential in non-tumor diseases like emphysema and pulmonary fibrosis.

Imofinostat (MPT0E028) (0-10 μM; 48 h) significantly inhibits cell proliferation and induces apoptosis in HCT116 cells[1].
Imofinostat (0-10 μM; 24 h) inhibits cell growth in a concentration-dependent manner. Imofinostat increases the number of cells in the sub-G1 phase of the cell cycle. Imofinostat induces caspase 3 and PARP activation in a concentrationdependent manner, and this apoptosis[1].
Imofinostat (0.3-100 μM; 24 h) induces significant concentration-dependent growth inhibition in Ramos and BJAB cells. Imofinostat increases the subG1 phase population in a time- and concentration-dependent manner. Imofinostat induces caspase-3, -6, -7, -8, -9 activation and PARP cleavage[2].
Imofinostat (0.01-1 μM) pretreated human lung fibroblasts (WI-38) for 30 minutes and then treated with stimulants, which inhibits the expression of CTGF induced by TGF-β, thrombin, and ET-1[5].
