Arylcarboxamide Derivatives as Promising HDAC8 Inhibitors: An Overview in Light of Structure-activity Relationship...

HDAC8 is associated with several disease conditions as well as various cancers of several organs and hematological malignancies. To counter such pathophysiological and disease conditions, inhibition of HDAC8 may be a promising approach for anticancer drug development. In this article, a detail of arylcarboxamide-based potential HDAC8 inhibitors has been outlined. Considering their binding pattern of interactions along with the chemical features, effective and selective novel HDAC8 inhibitors can be designed further. Therefore, modification of these compounds provides greater possibilities for the development of novel HDAC8 inhibitors. Nevertheless, structural modification of such arylcarboxamide derivatives may be able to produce potent dual-inhibitory compounds along with HDAC8 inhibition. Thus, this article is quite useful for exploring and identifying several possibilities for arylcarboxamide-based HDAC8 inhibitors. Moreover, it can be concluded that further study of the arylcarboxamide-based HDAC8 inhibitors can be effectively used for the treatment of different cancerous and non-cancerous diseases.
