Talacotuzumab 产品活性：Talacotuzumab (JNJ 56022473; CSL 362) 是一种 IgG1 型完全人源化的 CD123 中和单克隆抗体，含有修饰的 Fc 结构。Talacotuzumab 对 CD123、CD32b/c、CD16-158F、CD16-158V 的 KD 分别为 0.43 nM、188 nM、46 nM、16.8 nM。Talacotuzumab 抑制 IL-3 与 CD123 的结合，从而拮抗靶细胞中的 IL-3 信号传导。Talacotuzumab 使 Fc 区发生突变以增加对 CD16 (FcγRIIIa) 的亲和力，从而增强抗体依赖性细胞介导的细胞毒性 (ADCC)。Talacotuzumab 在体内非常有效地减少急性髓性白血病 (AML) 异种移植小鼠模型中的白血病细胞生长。 产品来源： https://www.medchemexpress.cn/talacotuzumab.html 研究领域：Immunology/Inflammation 作用靶点：Interleukin Related In Vitro: Talacotuzumab (JNJ 56022473; CSL 362) strongly mediates ADCC of TF-1 cells with an ic50 of 5 ng/ml (33 pM). Talacotuzumab (1 μg/ml; pretreatment for 24 hours) inhibits TLR7-stimulated (Imiquimod; HY-B0180; 0.5 μM; for 6 days) and TLR9-stimulated (CpG C; 0.5 μM; for 6 days) IFN-α production in both SLE donors and healthy donors plasmacytoid dendritic cells (pDCs) and basophils, whereas TLR4-stimulated (LPS; HY-D1056; 10 μg/ml) production is not significantly reduced. Talacotuzumab inhibits TLR7- and TLR9-induced plasmablast expansion and proliferation by depletion of plasmacytoid dendritic cells (pDCs). In Vivo: Talacotuzumab (JNJ 56022473; CSL 362; 300 μg; ip; thrice weekly for 5 weeks) results in a significant delay in tumor growth compared with an isotype control in acute myeloid leukaemia mice xenografts. Talacotuzumab (1, 10, 30 mg/kg; s.c.; single injection) has maximal serum concentrations at 48 hours of ~12, 190, and 380 μg/ml at doses of 1, 10, and 30 mg/kg in naive cynomolgus monkeys, respectively. 相关产品：Resatorvid | Disulfiram | Polyinosinic-polycytidylic acid | Raleukin | Deucravacitinib | Dupilumab | Tocilizumab | Apilimod | Oxidopamine hydrobromide | LMT-28 | Theophylline | Secukinumab | Clofazimine | Sodium metatungstate | Benzbromarone | SC144 | Hydrocortisone hemisuccinate | LY3509754 | ODN 2216 | Muscone | Diacerein | JTE-607 | Ixekizumab | APY0201 | Risankizumab | Lysophosphatidylcholines | Ustekinumab | Fibrinogen (Bovine) 品牌介绍: MCE (MedChemExpress) 拥有数百种全球独家化合物，我们致力于为全球科研客户提供最新最全的高品质小分子活性化合物；10,000 多种高选择性抑制剂、激动剂涉及各热门信号通路及疾病领域；设有专业的实验中心和严格的质控、验证体系；提供 LC/MS、NMR、HPLC、手性分析、元素分析等各项质检报告，确保产品的高纯度、高品质；产品的生物活性多经各国客户实验验证；Nature, Cell, Science 等多种顶级期刊及制药专利收录了MCE客户的科研成果；专业团队跟踪最新的制药及生命科学研究进展，为您提供全球最新的活性化合物；与世界各大制药公司及知名科研机构建立了长期的合作。
