Design and synthesis of highly TRAIL expression HDAC inhibitors based on ONC201 to promote apoptosis of colorectal cancer

Eur J Med Chem. 2022 May 27;238:114484. doi: 10.1016/j.ejmech.2022.114484. Online ahead of print.ABSTRACTActivation of the TRAIL proapoptotic pathway can promote cancer cell apoptosis. Histone deacetylases (HDACs) also are promising drug targets for cancers, and their synergistic effect with TRAIL can improve the inhibitory effect on cancer cells. Therefore, the development of highly TRAIL-sensitive HDAC inhibitors might be a promising strategy for the treatment of cancers. We synthesized a series of HDAC inhibitors by introducing effective fragments sensitive to TRAIL. Compound IIc showed good inhibitory activity against HDAC1 and HCT116 cells and showed higher sensitivity to activating the expression of the TRAIL protein and promoting the apoptosis of HCT-116 cells compared with ONC201. The inhibitory activity of compound IIc (25 mg/kg) in the HCT-116 xenograft model was significantly greater than those of the positive control drugs (ONC201, chidamide). These findings suggested that development of highly TRAIL-sensitive HDAC inhibitors as colorectal tumor cancer drugs.PMID:35649291 | DOI:10.1016/j.ejmech.2022.114484
