Identification of mitoxantrone as a new inhibitor of ROS1 fusion protein in non-small cell lung cancer cells

Abstract

Mitoxantrone, an FDA-approved drug for multiple sclerosis and hormone refractory prostate cancer, is identified as a potent inhibitor of ROS1 fusion protein by in silico screening in non-small cell lung cancer cells. Mitoxantrone can suppress the phosphorylation of ROS1 and subsequently inhibit its downstream signaling pathway and thus induce cell apoptosis.
