AMG-900是一种有效的,高选择性的pan-Aurora kinases抑制剂,作用于Aurora A/B/C,IC50为5 nM/4 nM/1 nM,作用于Aurora激酶比作用于p38α, Tyk2, JNK2, Met和Tie2选择性高10倍以上。
AMG900是一种高选择性的和口服生物可利用的Aurora激酶抑制剂,IC50值为5 nmol/L。
AMG900是Aurora激酶家族全部三个成员的抑制剂。该物质是在Aurora激酶的新型ATP竞争性二氮杂小分子抑制剂中发现的。AMG900可在肿瘤细胞中抑制Aurora-A和Aurora-B的自磷酸化,并能以不延长有丝分裂停滞的方式中断细胞分裂,引发细胞死亡。该物质能抑制26种不同的肿瘤细胞系增殖,同时,还具有提高其他aurora激酶抑制剂活性的能力。[1,2]
在动物水平上,AMG900被用于小鼠模型实验。在已建立的HCT116肿瘤小鼠中口服AMG900。相比溶剂对照组,使用不同浓度AMG900的实验组肿瘤体积明显更小。这些结果表明,AMG900具有显著抑制肿瘤生长的能力。
Information
AMG 900 is a potent and highly selective pan-Aurora kinasesinhibitor for Aurora A/B/C withIC50of 5 nM/4 nM /1 nM. It is >10-fold selective for Aurora kinases than p38α, Tyk2, JNK2, Met and Tie2. Phase 1.
In vitro
AMG 900 is a novel class of ATP-competitive phthalazinamine small molecule inhibitors of aurora kinases. In HeLa cells, AMG 900 inhibits autophosphorylation of aurora-A and -B as well as phosphorylation of histone H3 on Ser, a proximal substrate of aurora-B. The predominant cellular response of tumor cells to AMG 900 treatment is aborted cell division without a prolonged mitotic arrest, which ultimately results in cell death. AMG 900 inhibits the proliferation of 26 tumor cell lines, including cell lines resistant to the antimitotic drug paclitaxel and to other aurora kinase inhibitors (AZD1152, MK-0457, and PHA-739358), at low nanomolar concentrations (about 2- 3 nM). Furthermore, AMG 900 is active in an AZD1152-resistant HCT116 variant cell line that harbors an aurora-B mutation (W221L).
In vivo
Oral administration of AMG 900 blocks the phosphorylation of histone H3 in a dose-dependent manner and significantly inhibited the growth of HCT116 tumor xenografts. AMG 900 is broadly active in multiple xenograft models, including 3 multidrugresistant xenograft models, representing 5 tumor types. AMG 900 exhibits a low-to-moderate clearance and a small volume of distribution. Its terminal elimination half-life ranged from 0.6 to 2.4 hours. AMG 900 is well-absorbed in fasted animals with an oral bioavailability of 31% to 107%. Food intake has an effect on rate (rats) or extent (dogs) of AMG 900 oral absorption. The clearance and volume of distribution at steady state in humans are predicted to be 27.3 mL/h/kg and 93.9 mL/kg, respectively. AMG 900 exhibits acceptable PK properties in preclinical species and is predicted to have low clearance in humans.
