Novel Bioactive Hybrid Compound Dual Targeting Estrogen Receptor and Histone Deacetylase for the Treatment of Breast Cancer
摘要:
A strategy to develop chemotherapeutic agents by combining several active groups into a single molecule as a conjugate that can modulate multiple cellular pathways may produce compounds having higher efficacy compared to that of single-target drugs. In this article, we describe the synthesis and evaluation of an array of dual-acting ER and histone deacetylase inhibitors. These novel hybrid compounds combine an indirect antagonism structure motif of ER (OBHS, oxabicycloheptene sulfonate) with the HDAC inhibitor suberoylanilide hydroxamic acid (SAHA). These OBHS-HDACi conjugates exhibited good ER binding affinity and excellent ERa antagonistic activity, and they also exhibited potent inhibitory activities against HDACs. Compared with the approved drug tamoxifen, these conjugates exhibited higher antitumor potency in ER alpha-positive breast cancer cells (MCF-7). Moreover, these conjugates not only showed selective anticancer activity that was more potent against MCF-7 cells than DU 145 (prostate cancer), but they had no toxicity toward normal cells.

various cellular events such as transcription. Novel HDAC inhibitors were designed and synthesised to promote higher levels of recombinant protein production in tobacco cell cultures. The effect of these chemical enhancers on the epigenetic profiles in plant cells has been evaluated by molecular docking, in vitro and in vivo studies. The addition of these novel enhancers led to an increase in histone
