Epigenetic therapy is emerging as a promising approach against numerous human being diseases. Though, the epigenetic mechanisms are necessary for normal cellular functions, the aberrant epigenetic mechanisms, such as promoter DNA methylation, histone modification, and miRNA-mediated posttrancriptional modifications contributes to the spirit style related diseases. Unlike genetic modification, the epigenetic modifications are reversible and often identified in early stages of diseases. Thus, targeting aberrant epigenetic modification has gained considerable attention in cancer prevention. The concept of epigenetig drug (epidrug) is at the vanguard of drug discovery which some are either approved or under clinical trials. The global demand for
