Alteminostat (CKD-581; 1 nM-10 μM; 72 hours) treatment potently reduces cell viability in all four lymphoma cell lines in a concentration-dependent manner. The IC50 values of Alteminostat in SU-DHL-4, OCI-LY1, SU-DHL-2, and U2932 cells are 1.31 nM, 36.91 nM, 1.18 nM, and 31.99 nM, respectively. Alteminostat (CKD-581; 10-300 nM; 24 hours) treatment decreases the expression of BCL-6 as well as BCL-2 in cells. Alteminostat (CKD-581; 30-300 nM; 24 h) treatment results in γH2AX accumulation and PARP1 cleavage in SU-DHL-4, OCI-LY1, SU-DHL-2, and U2932 cells. Alteminostat decreases the protein levels of BCL-XL and MCL-1 in a concentration-dependent manner in OCI-LY1 cells. Alteminostat (CKD-581; 10-300 nM; 6 hours) treatment increases the acetylation of histone H3 in SU-DHL-2 cells. And tubulin acetylation also increased with 10 nM CKD-581. CKD-581 increased the acetylation of target molecules by inhibiting class I-II HDACs in lymphoma cells. |
