Lysine specific demethylase 1 (LSD1) and HDAC6 are epigenetic proteins associated with several diseases, including cancer and combined inhibition of these proteins could be highly beneficial in treating some cancers such as AML, MM and solid tumors. Multiple myeloma (MM) is a challenging cancer with fast relapse rate where novel treatment options are the need of the hour. We have designed and developed novel, LSD1 and HDAC6 selective dual inhibitors to target MM. Our dual inhibitor compound 1 shows superior potency in multiple MM cell lines. In MM.1S xenograft model compound 1 shows superior efficacy compared to single agent LSD1 and HDAC6 inhibitors by oral administration and is well tolerated. Further evaluation of the molecule in other cancers is in progress.

Precedential evidence ascertaining the overexpression of LSD1 and HDACs in colorectal cancer spurred us to design a series of dual LSD1-HDAC inhibitors. Capitalizing on the modular nature of the three-component HDAC inhibitory model, tranylcypromine as a surface recognition motif was appended to zinc-binding motifs via diverse linkers. A compendium of hydroxamic acids was generated and evaluated for cytotoxicity against HCT-116 cells (human colorectal cancer cell lines).

Dually targeting the epigenetic proteins lysine specific demethylase 1 (LSD1) and histone deacetylases (HDACs) that play a key role in cancer cells by modulating gene repressor complexes including CoREST will have a profound effect in inhibiting tumour growth. Here, we evaluated JBI-097 a dual LSD1/HDAC6 inhibitor, for its in vitro and in vivo activities in various tumor models. In vitro, JBI-097 showed a strong potency in inhibiting LSD1 and HDAC6 enzymatic activities with the isoform selectivity over other HDACs.

Defects in epigenetic pathways are key drivers of oncogenic cell proliferation. We developed a LSD1/HDAC6 multitargeting inhibitor (iDual), a hydroxamic acid analogue of the clinical candidate LSD1 inhibitor GSK2879552. iDual inhibits both targets with IC values of 540, 110, and 290 nM, respectively, against LSD1, HDAC6, and HDAC8.

Pragmatic insertion of pargyline, a LSD1 inhibitor, as a surface recognition part in the HDAC inhibitory pharmacophore was planned in pursuit of furnishing potent antiprostate cancer agents. Resultantly, compound elicited magnificent cell growth inhibitory effects against the PC-3 and DU-145 cell lines and led to remarkable suppression of tumor growth in human prostate PC-3 and DU-145 xenograft nude mouse models. The outcome of the enzymatic assays ascertained that the substantial antiproliferative effects of compound were mediated through HDAC6 isoform inhibition as well as selective MAO-A and LSD1 inhibition.
