名稱 | Hesperadin |
描述 | Hesperadin(IC50=250 nM) effectively inhibits Aurora B. It potently reduces the activity of AMPK, MAPKAP-K1, MKK1, Lck, CHK1 and PHK, but it could not inhibit MKK1 activity in vivo. |
細(xì)胞實驗 | HeLa cells and PtK1 cells are added Hesperadin 500 nM for 24 and 48 hours. |
激酶實驗 | For the Aurora B kinase assay, HeLa cells are lysed in a buffer containing 50 mM NaCl, then centrifuging at 13,000 rpm for 20 minutes at 4 °C. Discard supernatant, add 15 mL lysis buffer containing 250 mM NaCl in order to obtain active Aurora B kinase. Centrifuging at low-speed supernatant of the latter extract is used for immunoprecipitation. Monoclonal mouse anti–AIM-1, or mouse anti-HA, is coupled to GammaBind Plus Sepharose, and beads are rotated over-end in the extract for 90 minutes at 4 °C. Beads are washed, aliquoted, and washed in kinase buffer (20 mM Tris, pH 7.5, 150 mM NaCl, 10 mM MgCl2, 1 mM DTT, 10 mM NaF). The kinase assay is performed with 10 μL beads in 20 μL kinase buffer containing 5 μg histone H3, 10 μM ATP, 2.5 μCi [γ-32P]ATP, and different concentrations of Hesperadin for 20 minutes at 37 °C. |
體外活性 | 在HeLa細(xì)胞中,Hesperadin通過抑制Aurora B的功能,干擾染色體連接,造成有絲分裂和細(xì)胞質(zhì)分裂缺陷,導(dǎo)致細(xì)胞增殖停止和多倍體化。Hesperadin在20-100 nM濃度作用下,導(dǎo)致有絲分裂活化組蛋白H3在Ser10位點的磷酸化丟失。當(dāng)Hesperadin濃度達(dá)到1 μM時,其他激酶(AMPK, Lck, MKK1, MAPKAP-K1, CHK1, 和 PHK)活性顯著降低。在體外激酶測定中,Hesperadin(IC50 = 40 nM)阻斷了來自病原性錐蟲(Trypanosoma brucei)的TbAUK1(T. brucei Aurora kinase-1)對重組色質(zhì)組蛋白H3的磷酸化。Hesperadin(IC50 = 48 nM)顯著抑制了培養(yǎng)的傳染性血液形式(BF)細(xì)胞的生長,而以IC50 = 550 nM的濃度弱抑制了昆蟲循環(huán)階段(PF)細(xì)胞的生長。 |
