CFI-402257 is a selective inhibitor of Mps1, CFI-402257 inhibited Mps1 with an IC50 value of 1.2 ± 0.4 nM, and was ATP competitive with a Ki value of 0.09 ± 0.02 nM, It has high specificity, selectivity and potency [2,7].
CFI-402257 induces senescence-like responses and SASP secretion in HCC[1]. CFI-402257 suppresses MM(Malignant mesothelioma) growth. Mps-1 is overexpressed in MM and that its expression correlates with poor patients' outcome. In vitro, CFI-402257-mediated inhibition of Mps-1 resulted in abrogation of the mitotic checkpoint, premature progression through mitosis, marked aneuploidy and mitotic catastrophe[3]. CFI-402257, significantly inhibited GBM cell proliferation and improved the growth-suppressive effect of TMZ[4]. When evaluated the cellular effects of the potent clinical TTKi CFI-402257 in TNBC models. CFI-402257 induced apoptosis and potentiated aneuploidy in TNBC lines by accelerating progression through mitosis and inducing mitotic segregation errors[6].
In BALB/cAnN - nu mice, TTK inhibition by CFI-402257 shrank HCC tumors and reduced lung metastasis[1]. Oral QD of CMI-402257 showed dose-dependent activity in mice with established tumors in xenografts of MDA-MB-231 human TNBC cells[2]. Developed a panel of CDK4/6i-resistant breast cancer cell lines and patient-derived organoids, TTK inhibitor CFI-402257 as a therapeutic strategy for a defined subset of ER+ breast cancer patients who develop resistance to CDK4/6i[6].
