Gossypol suppresses tumorigenesis through inhibition of multiple deubiquitinating enzymes. (PubMed, Bioorg Chem)
Moreover, Gossypol exhibited cytotoxic effects on human breast, prostate, and colorectal cancer cell lines, at least partially through downregulating the oncogenic substrates of targeted DUBs such as c-Myc, Mcl-1, MDM2, and Cyclin D1. Collectively, our findings position Gossypol as a promising small-molecule inhibitor targeting DUBs, especially USPs, and provide a rationale for further exploring its therapeutic potential in USP-driven cancers.
