BC2059 是β-Catenin 拮抗剂,能够破坏 β-catenin 与转导素 β 样蛋白 1 (TBL1) 结合。
产品描述 | BC2059 is a small molecule inhibitor of the Wnt/beta-catenin pathway with potential antineoplastic activity. |
体外活性 | BC2059 induces apoptosis in primary multiple myeloma samples in vitro, causing minimal apoptosis on healthy peripheral blood mononuclear cells[1]. |
体内活性 | BC2059 synergizes with the proteasome inhibitor bortezomib both in HMCL and primary multiple myeloma samples. Finally, in xenograft models of human myelomatosis, BC2059 delays tumor growth and prolongs survival with minor on-target side effects. Collectively, these results demonstrate the efficacy of targeting the Wnt/β-catenin pathway with BC2059 both in vitro and in vivo, at clinically achievable doses[1]. |
细胞实验 | For β-catenin knockdown, 2 mL of 2 × 10^5/mL KMS18 cells were plated into a 12-well plate at day 0 (KMS18 doubling time: 36 hours).?At day 1, media were replaced by 1 mL of Opti-MEM , and transfection was carried out with Lipofectamine RNAiMAX .?For β-catenin knockdown, we used SignalSilence β-catenin siRNA I and β-catenin siRNA II (Cell Signaling Technology) at concentrations recommended by the manufacturer, whereas Silencer Negative Control No. 1 siRNA ?was used as a negative control, at the same concentration.?Six hours after the transfection, 1 mL of fresh media (RPMI-10% FCS) was added in every well.?At days 2 and 3, cells were treated with BC2059 (50, 100, 150 nmol/L) and then harvested at day 4 (72 hours after transfection).?Cell death was monitored by PI staining with FACS, whereas untreated cells were collected for β-catenin protein level measurement by immunoblotting.?Cells were lysed with RIPA lysis buffer, and 70 μg of protein was separated by 6% SDS-PAGE and blotted onto PVDF as already described.?β-Actin (mouse mAb HRP conjugate;?Cell Signaling Technology) was used as a loading control[1]. |
动物实验 | Adult age-matched Cg-Prkdcscid Il2rgtm1Wjl/SzJ mice were injected (intravenously) with 1 × 10^6 U266 HMCL, carrying the FUL2-TGvector .?At day 21, a limited course of treatment was commenced after confirmation of established measurable disease by bioluminescence.?Control mice (n = 4) received 17% Solutol HS 15 whereas treated mice received 5 (n = 4) or 10 mg/kg BC2059 (n = 5) twice a week intravenously for 3 consecutive weeks (6 doses in total).?Tumor burden was monitored on a weekly basis by in vivo imaging, from the second week of the experiment (day 18) until the first mice reached scientific endpoints.?Briefly, mice were anaesthetized, injected intraperitoneally with 125 mg/kg luciferin, and imaged with the Lumina III XR system.?Acquisition and analysis were performed with the Living Image system.?Peripheral blood counts were evaluated sequentially during the course of the experiment .Upon reaching scientific endpoints (hind limp paralysis, >20% weight loss), mice were humanely euthanized and tissues (skin and colon) were collected.?Tissues were formalin fixed and embedded in paraffin, sectioned, and stained with H&E and β-catenin antibody.?Images were taken with an Olympus BX51 microscope[1]. |

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。
