MLN8237 (Alisertib),1028486-01-2,IC-0202037

Alisertib (MLN8237), as an investigational, orally available, selective aurora A kinase inhibitor, is usually used for the treatment of solid tumors and hematologic malignancies.[1]
In vitro experiment it shown that treatment with 0.05 μM- 0.5 μM MLN8237 in the leukemia, medulloblastoma, and neuroblastoma cell lines inhibited their cell growth maximumly. However, with >1 μM approximately MLN8237, there was a paradoxical increase in apparent survival in all three lines, most pronounced for Daoy medulloblastoma cell line.[2] In vitro, MLN8237 is effective against both Ewing sarcoma and neuroblastoma cell lines with IC50 of 32 nM and 37 nM, respectively.[4] And alisertib has growth inhibition against U-2 OS cells and MG-63 cells with IC50 of 16.6 μM and 9.5 μM, respectively.[5] In addition, MLN8237 has aggressive inhibition against B-NHL cell proliferation with an IC50 of 10-50 nM and induced apoptosis with a dose- and time-dependent manner.[6]
In vivo, treatment with 30 mg/kg the combination of alisertib and lenvatinib intraperitoneally, every 3 days, for 4 consecutive weeks in BALB/c athymic nude mice, significantly enhanced the antiproliferative and proapoptotic
