YH-0623 is an orally active mitochondrial RNA polymerase (POLRMT) inhibitor (IC50 = 50.48 nM, Nanoluciferase Bioluminescence Resonance Energy Transfer (NanoBRET) assay). YH-0623 exhibits antiproliferative effects on 22Rv1 cells by reducing the expression of mitochondrial-related genes. YH-0623 inhibits 22Rv1 cell growth, colony formation, and the expression of OXPHOS-related proteins. YH-0623 significantly inhibits tumor growth in a prostate cancer xenograft mouse model. YH-0623 is indicated for prostate cancer research[1].
