生物活性

BG45 is a potent HDAC3 inhibitor with IC50 values of 0.289, 2, 2.2 and ﹥20 μM for HDAC3, HDAC1, HDAC2 and HDAC6, respectively. BG45 selectively targets multiple myeloma (MM) cells and induces caspase-dependent apoptosis.

体外研究(In Vitro)

BG45 (1.875-30 μM; 48 and 72 h) targets multiple myeloma (MM) cells and inhibits cell growth in a dose-dependent manner.
BG45 (15 μM; 0-48 h; MM.1S cells) induces apoptosis via caspase-3/PARP cleavage.
BG45 (10 and 20 μM; 12 h; MM.1S cells) induces acetylation of histone H2A, H3, and H4 in a dose-dependent manner.
BG45 (10 and 20 μM; 10 h; MM.1S cells) induces multiple myeloma (MM) cells toxicity is associated with hyperacetylation of histones and STAT3 and downregulation of p-STAT3.
