Aliertib (MLN 8237) 是一种口服活性和选择性的Aurora A激酶抑制剂 (IC50=1.2 nM),与Aurora A 激酶结合,导致有丝分裂纺锤体异常、有丝分裂累积。Aliertib (MLN 8237) 通过靶向白血病细胞中的AKT/mTOR/AMPK/p38途径诱导其凋亡和自噬。具有抗肿瘤活性。
生物活性 | Alisertib (MLN 8237) is an orally active and selectiveAurora Akinaseinhibitor (IC50=1.2 nM), which binds toAurora Akinase resulting in mitotic spindle abnormalities, mitotic accumulation. Alisertib (MLN 8237) inducesapoptosisandautophagythrough targeting theAKT/mTOR/AMPK/p38pathway in leukemic cells. Antitumor activity[1][2][3]. |
IC50& Target[3] | Aurora A 1.2 nM (IC50) | Aurora B 396.5 nM (IC50) |

体外研究 (In Vitro) | Alisertib (MLN 8237) leads the MM cells to mitotic spindle abnormalities, mitotic accumulation, as well as inhibition of cell proliferation through apoptosis and senescence. Alisertib up-regulates p53 and tumor suppressor genes p21 and p27[1]. The decreased activity of Alisertib (MLN 8237) for the T217D/W277E Aurora A/TPX2 complex may reflect the increased affinity for ATP induced by cofactor binding to Aurora A[2]. Alisertib (MLN 8237) inhibits cell proliferation with IC50s ranging from 15 to 469 nM in different tumer cell lines[4].

体内研究 (In Vivo) | Alisertib (MLN 8237) (30 mg/kg, p.o.) significantly reduces tumor burden and increases overall survival in xenograft-murine model of human-MM[1]. Alisertib (3-30 mg/kg; p.o.; once daily for 3 weeks) causes tumor growth inhibition in solid tumor xenograft models[4].
Animal Model: | Nude mice bearing HCT-116 colon tumor xenograft[4] | Dosage: | 3, 10, or 30 mg/kg | Administration: | P.o.; once daily for 3 weeks | Result: | Resulted in a dose-dependent TGI (tumor growth inhibition) of 43.3%, 84.2%, and 94.7% for the 3, 10, and 30 mg/kg groups,respectively. |
