基本信息： CAS：163515-35-3 分子式：C158H256N52O48S11 分子量：3995.7 纯度：97% 级别：BR 序列：MCMPCFTTDHQMARKCDDCCGGKGRGKCYGPQCLCR-NH2 (Disulfide bridge: Cys2-Cys1 9,Cys5-Cys28,Cys16-Cys33,Cys20-Cys35); Met-Cys-Met-Pro-Cys-Phe-Thr-Thr-Asp-His-Gln-Met-Ala-Arg-Lys-Cys-Asp-Asp-Cys-CysGly-Gly-Lys-Gly-Arg-Gly-Lys-Cys-Tyr-Gly-Pro-Gln-Cys-Leu-Cys-Arg-NH2 (Disulfide bridge: Cys2-Cys19,Cys5-Cys28,Cys16-Cys33,Cys20-Cys35); 性状：乳白色粉末 产品简介： 氯毒素（Chlorotoxin）是从雷蛇属以色列蝎子的毒液中提取的由36个氨基酸组成的肽段，具有抗癌活性。Chlorotoxin是氯离子通道 (chloride channel) 阻断剂。U251MG 细胞迁移抑制剂。 作⽤靶点：Chloride Channel 作⽤通路：Membrane Transporter/Ion Channel 体外研究： Chlorotoxin (Chlorotoxin) preferentially binds to tumor cells and has been harnessed to develop an imaging agent to help visualize tumors during surgical resection. In addition, chlorotoxin has potential as a vehicle to deliver anti-cancer drugs specifically to cancer cells. Chlorotoxin is shown to bind glioma cells, but is unable to bind normal rat astrocytes and Te671, a human rhabdomyosarcoma cell line. Chlorotoxin inhibits the migration of U251MG (glioma) cells, with an IC50 of 600 nM. Chlorotoxin binds to glioma cells is specific and involves high affinity (Kd=4.2 nM) and low affinity (Kd=660 nM) binding sites.Small conductance chloride channels are shown to be potently blocked by Chlorotoxin. Chlorotoxin has been used as a general pharmacological tool to investigate the function of chloride channels. 体内研究： Chlorotoxin shows insecticidal activity on insects and other invertebrates. After the administration of I-Chlorotoxin to tumor-bearing mice, the peptides accumulated within the tumor.Chlorotoxin selectively accumulates in the brain of tumor-bearing mice with calculated brain: muscle ratios of 36.4% of injected dose/g (ID/g), as compared to 12.4%ID/g in control animals. |
