Discovery of novel itaconimide-based derivatives as potent HDAC inhibitors for the efficient treatment of prostate cancer.

Histone deacetylases (HDACs) are a family of enzymes that play important roles in the development and progression of cancers. Inhibition of HDACs has been widely studied as a therapeutic strategy in the development of anticancer drugs. However, developing HDAC inhibitors that are effective for solid tumors remains a great challenge. In this work, we designed and synthesized a series of itaconimide-based derivatives as potent HDAC inhibitors. Among them, compound 17q exhibited potent inhibition of HDAC1/2/3/6, with good antiproliferative activity in vitro and an excellent pharmacokinetic profile. Compound 17q significantly inhibited tumor growth in a DU145 xenograft tumor model and showed no obvious toxicity. Moreover, when 17q was combined with other prostate cancer therapeutics, outstanding synergistic effects were observed and the toxic side effects of DTX were reduced. Overall, based on the data, these inhibitors may offer promising new targeted therapies for prostate cancer. Copyright © 2024 Elsevier Masson SAS. All rights reserved.
