Miclxin (DS37262926) is a novel MIC60 inhibitor that induces apoptosis through mitochondrial stress in mutant tumor cells via β-catenin.Miclxin is a potent inhibitor of mutant β-catenin, which is involved in the Wnt signaling pathway.Miclxin induces β-catenin-dependent apoptosis, leading to mitochondrial damage and loss of mitochondrial membrane. Miclxin has anti-tumor activity and kills tumors by targeting MIC60.
