描述 | The Aurora family of serine/threonine kinases, which consists of Aurora A, B and C, plays an important role in chromosome alignment, segregation, and cytokinesis during mitosis. Alisertib is a selective Aurora A kinase inhibitor with IC50 value of 1.2nM versus 396.5nM for Aurora B (measured by enzymatic assay). Consistent with inhibition by Aurora A on cell phenotype, treatment with 50nM Alisertib casued an increase in cells in the G2/M phase at 24 and 48 hours in HCT-116 cells, as well as caused mitotic spindle abnormalities and chromosome misalignment in cells. However, at a higher concentration of 0.25 or 1μM, Alisertib caused an increase in the number of cells with 8N DNA content and multinuclear in cells, as phenotypes consistent with Aurora B inhibition. Alisertib can inhibit cell proliferation, including HCT-116, SW480, DLD-1, H460, MDA-MB-231, PC3, SKOV3, HPAC, OCI-LY-3, OCI-LY-7, OCI-LY-10, OCI-LY-19 and WSU cell lines, with IC50 values ranging in 15-469nM, suggesting its widely anti-proliferative effect on colon, lung, breast, prostate, ovarian, pancreatic and lymphoma tumor. Alisertib possessed good pharmacodynamics as orally dosed at 3, 10, and 30mg/kg with Alisertib resulted in a time- and dose-dependent increase in the mitotic marker p-HisH3, suggesting Aurora A inhibition, in tumor tissue from HCT-116 xenografts. Misaligned chromosomes and reduced bipolar mitotic spindles can also be observed. Oral administration of Alisertib at 3, 10, and 30 mg/kg once daily for 21 consecutive days dose-dependently inhibit tumor growth in nude mice bearing subcutaneous HCT-116 tumors. The broad antitumor activity of Alisertib can also be observed in a diverse set of solid tumor xenograft models as well as regressions in in vivo models of lymphoma, including the cell lines mentioned above[1]. | ||
