Histone deacetylase (HDAC) inhibitors have emerged as promising cancer therapeutics due to their ability to induce differentiation, cell cycle arrest, and apoptosis in cancer cells. In the present review, we have described the systemic discovery and development of HDAC inhibitors. Researchers across the globe have identified various small molecules like benzo[d][1,3]dioxol derivatives, belinostat analogs, pyrazine derivatives, quinazolin-4-one-based derivatives, 2,4-imidazolinedione derivatives, acridine hydroxamic acid derivatives, coumarin derivatives, tetrahydroisoquinoline derivatives, thiazole-5-carboxamide, salicylamide derivatives, β-peptoid-capped HDAC inhibitors, quinazoline derivatives, benzimidazole and benzothiazole derivatives, and β- elemene scaffold containing HDAC inhibitors. Most of the scaffolds have shown attractive IC50 (μM) in various cell lines like HDAC1, HDAC2, HDAC6, PI3K, HeLa, MDA-MB-231, MCF-10A, MCF-7, U937, K562 and Bcr-Abl cell lines.
