This study identified a new human mitoNEET binding ligand (NTS-01) that specifically binds to the human mNT protein and stabilizes its [2Fe-2S] clusters under oxidative conditions in vitro. Treatment with NTS-01 induces mitochondrial fragmentation and reduces ovarian cancer cell proliferation. The NTS-01 molecule represents a promising lead compound for further drug design studies against ovarian cancer.
Human NEET proteins play an important role in a variety of diseases, including cancer. Using the recently published X-ray structure of the human mNT-M1 complex, we screened a commercial chemical compound library and identified a new human mitoNEET (mNT) binding ligand (NTS-01). Biochemical investigations revealed that NTS-01 specifically binds to the human mNT protein and stabilizes its [2Fe-2S] clusters under oxidative conditions in vitro. Treatment of ovarian cancer cells with NTS-01 induces ovarian cancer (SKOV-3) mitochondrial fragmentation (fission) and reduces ovarian cancer cell proliferation in a 2D single-layer cell culture, as well as in a 3D-spheroids culture. The NTS-01 molecule represents therefore a new lead compound for further drug design studies attempting to develop efficient treatment against ovarian cancer.
