ClassIhistonedeacetylase (HDAC) enzymes 1, 2, and 3 organize chromatin as the catalytic subunits within seven distinct multiprotein corepressor complexes and are established drug targets. We report optimization studies of benzamide-based Von Hippel–Lindau (VHL) E3-ligase proteolysis targeting chimeras (PROTACs) and for the first time describe transcriptome perturbations resulting from these degraders

simultaneously targets histone deacetylase (HDAC) and macrophagemigrationinhibitoryfactor (MIF). The HDAC/MIF dual inhibitor proved to be toxic for EGFR mutated (H1650, TKI-resistant) or knock out (A549 EGFR−/−) NSCLC cell lines. Further experiments showed that HDAC inhibition inhibits cell survival and proliferation, while MIF inhibition downregulates pAKT or AKT expression level, which both interfere
The novel benzamide derivative represented by formula (1) and the novel anilide derivative represented by formula (13) of this invention has differentiation-inducing effect, and are, therefore, useful a therapeutic or improving agent for malignant tumors, autoimmune diseases, dermatologic diseases and parasitism. In particular, they are highly effective as an anticancer drug, specifically to a hematologic malignancy and a solid carcinoma.
