Although targeted therapy for renal cell carcinoma (RCC) has achieved good therapeutic effects in clinic, a considerable number of patients develop drug resistance over time. So, there is still an urgent need to develop new drugs for RCC treatment. As LSD1 is considered as a promising drug target in diverse cancers, including RCC, we tried to find new LSD1 inhibitor using drug repurposing strategy from a compound library, and fenoldopam, an FDA-approved drug, was identified as a potent LSD1 inhibitor with IC50 = 0.8974 μM in a reversible manner. Molecular docking predicted that fenoldopam occupied the FAD cavity of LSD1, forming hydrogen bonds with surrounding residues. Moreover, fenoldopam inactivated LSD1 and performed antiproliferative activity against ACHN cells and promoted cells apoptosis in vitro. Taken together, fenoldopam was identified as a novel LSD1 inhibitor firstly, and may serve as a new skeleton for RCC therapy.
