名稱 | Tozasertib |
描述 | Tozasertib (MK-0457) is a pan-Aurora kinase inhibitor (Kis: 0.6/18/4.6 nM for Aurora A/Aurora B/Aurora C). It shows selectivity against more than 190 different kinases. |
細胞實驗 | Logarithmically growing MCF-7 cells were incubated with either VX-680 or DMSO for 48 h. Single-cell suspensions were fixed in 70% ethanol for 15 min, incubated with RNase (1 mg/ml) at 37 °C for 30 min, labeled with 400 μl propidium iodide (50 μg/ml) for at least 15 min at room temperature. Cell-cycle profiles were determined by flow cytometric analysis [1]. |
激酶實驗 | Recombinant Aurora-1 (62-344), Aurora-2 (1-403) and Aurora-3 (1-309) were expressed as N-terminal, His6-tagged fusion proteins using a baculovirus expression system. The proteins were purified by affinity chromatography using Ni-NTA agarose, followed by size exclusion using a Superdex 200 26/60 column. Inhibition of kinase activity was assessed using a standard enzyme-coupled system or a radiometric, phosphocellulose-peptide capture assay as previously described [1]. |
動物實驗 | For the HL-60 study, female athymic NCr-nu mice were inoculated subcutaneously with 10^7 HL-60(TB) leukemia cells into the right axillary area. Treatment was administered i.p. b.i.d. after tumors reached 150–200 mm^3. VX-680 was prepared in a vehicle of 50% PEG 300 in 50 mM phosphate buffer. Cisplatin, formulated in saline, was administered i.p. q.4.d. for a total of three injections, at a dose of 5.4 mg/kg. For the MIA PaCa-2 studies, female MF1 nude mice were inoculated with 10^7 MIA PaCa-2 cells into the dorsal flank. Treatment was administered i.p. b.i.d. after tumors reached 175 mm^3. VX-680 was prepared in a vehicle of 50% PEG 300 in 50 mM phosphate buffer. 5-fluorouracil, formulated in saline, was administered i.v. q.4.d. at a dose of 50 mg/kg. For the HCT116 study, female Hsd RH rnu/nu rats were inoculated with 10^7 HCT116 cells into the right flank. Treatment was administered once the tumors reached 700–950mm^3. VX-680 was administered continuously through an indwelling femoral catheter, followed by a saline infusion for 4 d before repeating the dose cycle. For all studies, tumor volume was determined by caliper measurements three times a week [1]. |
體外活性 | Tozasertib (VX-680) 是三種Aurora激酶的強效抑制劑,其表觀抑制常數(shù)(Ki(app))分別為Aurora-A、Aurora-B和Aurora-C的0.6、18及4.6 nM。VX-680導致細胞聚集在4N DNA含量處,并強力抑制了多種腫瘤細胞類型的增殖,IC50值在15至113 nM之間[1]。不同的甲狀腺癌細胞(ATC細胞)經VX-680處理后,其增殖在時間和劑量上表現(xiàn)出依賴性抑制,IC50值在25至150 nM之間。VX-680顯著阻礙了不同細胞系在軟瓊脂中形成菌落的能力。通過對半胱天冬酶-3活性的分析表明,VX-680在不同細胞系中誘導了凋亡[2]。 |
體內活性 | 在裸鼠體內,用Tozasertib以每日兩次,每次75 mg/kg的劑量通過腹腔注射(b.i.d. i.p.)治療13天后,與對照組相比,平均腫瘤體積減少了98%。在十只動物中有四只的最終腫瘤體積比治療前的初始體積還要小。腫瘤生長的減少與劑量成正比,且在12.5 mg/kg b.i.d.劑量下顯著。Tozasertib具有良好的耐受性,僅在最高劑量下觀察到體重輕微下降(75 mg/kg b.i.d.時,體重下降5%)。Tozasertib還在胰腺和結腸異種移植模型中誘導腫瘤退縮。在一個確立的人類胰腺(MIA PaCa-2)異種移植模型中,用Tozasertib以每日兩次,每次50 mg/kg通過腹腔注射(b.i.d i.p.)治療,使得十個腫瘤中有七個出現(xiàn)退縮,并且與治療前的初始腫瘤體積相比,平均腫瘤體積減少了22% [1]。 |
