چکیده انگلیسی
Development of multifunctional transcriptional activators is of increasing importance as they could trigger complicated gene networks. Recently, we developed a differential gene activating multifunctional small molecule SAHA-PIP (Sδ) by conjugating a histone deacetylase (HDAC) inhibitor, SAHA, to a selective DNA-binding pyrrole-imidazole polyamide (PIP). Epigenetic activity of Sδ was attributed to the active metal-binding (-NHOH) domain of SAHA. We synthesized a derivative of Sδ, called Jδ to evaluate the role of surface recognition domain (-phenyl) of SAHA in Sδ-mediated transcriptional activation. In vitro studies revealed that Jδ displayed potent inhibitory activity against HDAC8. Jδ retained the pluripotency gene-inducing ability of Sδ when used alone and in combination with Sδ; a notable increase in the pluripotency gene expression was observed. Interestingly, Jδ significantly induced the expression of HDAC8-controlled Otx2 and Lhx1. Our results suggest that the epigenetic activity of our multifunctional molecule could be altered to improve its efficiency as a transcriptional activator for intricate gene network(s).
