Histone deacetylases (HDACs) represent novel molecular targets for the treatment of various types of cancers including multiple myeloma (MM). Many HDAC inhibitors have already shown remarkable anti-tumor activities in the preclinical studies, however, their clinical utility is limited due to unfavorable toxicities associated with their broad range HDAC inhibitory effects. BG45 is a novel small molecule HDAC3-selective inhibitor.
In vitro: BG45 is reported as an HDAC class I inhibitor with selectivity for HDAC3 over HDAC1, 2. Consistent with HDAC3 knockdown data, BG45 significantly inhibited MM cell growth dose-dependently. Importantly, BG45 also triggered a potent growth inhibitory effect against patient-derived MM cells, without affecting normal donor PBMCs .
In vivo: BG45 significantly inhibited MM tumor growth in a dose-dependent fashion. For example, significant differences were observed in control versus BG45 15 mg/kg, control versus BG45 50 mg/kg, and BG45 15 mg/kg versus BG45 50 mg/kg at day 22. Moreover, BG45 50 mg/kg in combination with bortezomib enhanced either single agent activity further. These results confirmed that BG45 triggers in vivo anti-MM activities .
Clinical trial: Up to now, BG45 is still in the preclinical development stage.
