Birinapant 是一种二价 Smac 模拟物,是 XIAP 和 cIAP1的强效拮抗剂,Kd 值分别为 45 nM 和小于 1 nM。它靶向与 TRAF2 相关的 cIAP,并消除 TNF 诱导的 NF-κB 活化。
产品描述 | Birinapant is a synthetic small molecule that is both a peptidomimetic of second mitochondrial-derived activator of caspases (SMAC) and inhibitor of IAP (Inhibitor of Apoptosis Protein) family proteins, with potential antineoplastic activity. |
靶点活性 | cIAP1:<1 nM(Kd), XIAP:45 nM(Kd) |
体外活性 | Birinapant binds with XIAP and cIAP1 with Kd of 45 and <1 nM, respectively. Birinapant induces cell death as a single agent in TRAIL-insensitive SUM190 (ErbB2-overexpressing) cells (IC50, ~300 nM), and significantly increases potency of TRAIL-induced apoptosis in TRAIL-sensitive SUM149 (triple-negative, EGFR-activated) cells. Birinapant causes rapid cIAP1 degradation, caspase activation, PARP cleavage, and NF-κB activation. [1] Birinapant in combination with TNF-α exhibits a strong antimelanoma effect in vitro. Birinapant in combination with TNF-α(1 ng/mL) inhibits the growth of human melanoma cell lines WTH202, WM793B, WM1366 and WM164 with IC50s of 1.8, 2.5, 7.9 and 9 nM, respectively, while neither compound is effective individually. Birinapant singly treatment induces inhibition on proliferation of WM9 cells with IC50 of 2.4 nM. Birinapant significantly inhibits the target protein cIAP1 and cIAP2 in these cell lines.[2] |

激酶实验 | Fluorescence polarization assay: The binding affinities of compounds to XIAP and cIAP1 are determined using a fluorogenic substrate and are reported as Kd values. Initially, the dissociation constant (Kd) for the fluorescently labeled modified Smac peptide (AbuRPF-K(5-Fam)-NH2; FP pep-tide) is determined using a fixed concentration of peptide (5 nM) and titrating varying concentrations of protein (0.075–5 μM in half log dilutions). The dose–response curves are produced by a nonlinear least squares fit to a single-site binding model using GraphPad Prism, with 5 nM of FP peptide and 50 nM of XIAP used in the assay. Various concentrations of Smac mimetics (100–0.001 μM in half log dilutions) are added to FP peptide:protein binary complex for 15 min at room temperature in 100μL of 0.1 M potassium phosphate buffer, pH 7.5, containing 100 mg/mL bovine c -globulin. Following incubation, the polarization values are measured on a multi-label plate reader using a 485 nm excitation filter and a 520 nm emission filter. |
细胞实验 | Cells are allowed to attach for 24 hours and subsequently incubated with Birinapant and/or TNF-α for 24 or 72 hours. Then MTS assay is conducted(Only for Reference) |

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。
