产品描述 | Mitoxantrone (mitozantrone) is an anthracenedione antibiotic with antineoplastic activity. Mitoxantrone intercalates into and crosslinks DNA, thereby disrupting DNA and RNA replication. This agent also binds to topoisomerase II, resulting in DNA strand breaks and inhibition of DNA repair. Mitoxantrone is less cardiotoxic compared to doxorubicin. |
靶点活性 | PKC:8.5 μM. |
体外活性 | Mitoxantrone induces DNA fragmentation and the proteolytic cleavage of poly(ADP-ribose) polymerase (PARP), a marker of the activation of caspases, in all the patients studied, demonstrating that the cytotoxic effect of mitoxantrone is due to induction of apoptosis. [1] Mitoxantrone activates NFkappaB and stimulates IkappaBalpha degradation in the promyelocytic leukemia cell line HL60 but not in the variant cells, HL60/MX2 cells, which lack the beta isoform of topoisomerase II and express a truncated alpha isoform that results in an altered subcellular distribution. [2] Mitoxantrone inhibits proliferation of activated PBMCs, B lymphocytes, or antigen-specific T-cell lines (TCLs) stimulated on antigen-presenting cells (APCs) in a dose-dependent manner. Mitoxantrone induces apoptosis of PBMCs, monocytes and DCs at low concentrations, whereas higher doses causes cell lysis. [3] |
体内活性 | Mitoxantrone transiently decreases the growth rate of HID xenografts in mice but does not affect that of PAC120 xenografts. [4] Mitoxantrone results in the severity of the cardiac lesions and the nephropathy and the intestinal toxicity in spontaneously hypertensive rats. Mitoxantrone and iron(III) form a strong 2:1 complex, in which mitoxantrone may be acting as a tridentate ligand. [5] |
激酶实验 | activity-based protein profiling (ABPP): Mouse brains are Dounce-homogenized in PBS, pH7.5, followed by a low-speed spin (1,400×, 5 min) to remove debris. The supernatant is then subjected to centrifugation (64,000×, 45 min) to provide the cytosolic fraction in the supernatant and the membrane fraction as a pellet. The pellet is washed and resuspended in PBS buffer by sonication. Total protein concentration in each fraction is determined using a protein assay kit. Samples are stored at -80 °C until use. Mouse brain membrane proteomes, are diluted to 1 mg/mL in PBS and pre-incubated with varying concentrations of inhibitors (1 nM to 10 mM) for 30 min at 37 °C before the addition of FP-rhodamine at a final concentration of 2 mM in a 50 mL total reaction volume. After 30 min at 25 °C, the reactions are quenched with 4×SDS-PAGE loading buffer, boiled for 5 min at 90 °C, subjected to SDS-PAGE and visualized in-gel using a flatbed fluorescence s |
细胞实验 | The human breast carcinoma cell lines MDA-MB-231 and MCF-7 are seeded in standard 96-well plates. One day after seeding, the culture medium is changed and replaced by medium containing different concentration of Mitoxantrone (10-5 to 5 μM) with or without DHA (30 μM) during 7 days. Viability of cells are measured as a whole by the tetrazolium salt assay[3]. |

请在以下方框中输入您的动物实验信息后点击计算,可以得到母液配置方法和体内配方的制备方法: 比如您的给药剂量是10 mg/kg,每只动物体重20 g,给药体积100 μL,一共给药动物10 只,您使用的配方为5% DMSO+30% PEG300+5% Tween 80+60% ddH2O。那么您的工作液浓度为2 mg/mL。
母液配置方法:2 mg 药物溶于 50 μL DMSO (母液浓度为 40 mg/mL), 如您需要配置的浓度超过该产品的溶解度,请先与我们联系。
体内配方的制备方法:取 50 μL DMSO 主液,加入 300 μL PEG300, 混匀澄清,再加 50 μL Tween 80,混匀澄清,再加 600 μL ddH2O, 混匀澄清。
