产品描述 | HAMNO (NSC-111847) is a protein interaction inhibitor of replication protein A (RPA). |
靶点活性 | RPA: |
体外活性 | HAMNO inhibits colony formation in both HNSCC cell lines. The combination of HAMNO with etoposide markedly inhibits colony formation to a greater degree than HAMNO alone. In UMSCC38 cells, HAMNO dose-dependently increased the occurs of pan-nuclear γ-H2AX staining. UMSCC38 and UMSCC11B cells have prominent γ-H2AX staining, particularly after incubation with HAMNO (20 μM). In UMSCC38 and OKF4 cells, HAMNO increased γ-H2AX staining, with the greatest increase in signal occurring in S-phase. |
体内活性 | In mice, HAMNO inhibits the progression of UMSCC11B tumors. After treatment with etoposide (20 μM, 2 h), Ser33 of RPA32 (an ATR substrate) is highly phosphorylated, which is reduced with the addition of 2 μM HAMNO and is nearly absent at higher concentrations, demonstrating HAMNO can inhibit RPA32 phosphorylation by ATR. |
细胞实验 | Cell cycle assessment and γ-H2AX staining are monitored in UMSCC38 and OKF4 cells after 2 h incubation with HAMNO (2, 20, 50 μM) and fixed in 70% ethanol overnight. Cells are washed with PBS and incubated overnight in PBS containing 1% BSA, 10% goat serum, and PS139-H2AX antibodies washed and incubated in goat anti-mouse Alexa Fluor 647 antibody for 30 min at room temperature. Cells are incubated in 50 μg/mL propidium iodide and 100 μg/mL RNase A for 30 min, and 10,000 cells per sample are analyzed. |
动物实验 | UMSCC38 and UMSCC11B cells are implanted into 6-week-old female mice by a single subcutaneous injection of tumor cells (2 to 6×105 cells in 100 mL of sterile PBS). The growth rates of tumors are determined by daily monitoring of tumor volume with vernier calipers [tumor volume=1/2(length×width2)]. Once the tumor size reaches 50 mm3, etoposide (10 mg/kg mouse) and HAMNO (2 mg/kg) are administered intraperitoneally every day for 3 days. Tumor size is monitored daily and the volume of the tumor is compared among all experimental groups. |

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。
