产品描述	TW-37 is an nonpeptide inhibitor to recombinant Bcl-2, Bcl-xL and Mcl-1 (Ki: 0.29/1.11/0.26 μM).
靶点活性	BCL-XL:1.11 μM(Ki), BCL2:0.29 μM(Ki), MCL1:0.26 μM(Ki)
体外活性	TW-37 targets the BH3-binding groove in Bcl-2 where proapoptotic Bcl-2 proteins bind, and shows higher affinity and selectivity for Bcl-2 and Mcl-1 over Bcl-xL with Ki values of 0.29 μM, 0.26 μM and 1.11 μM, respectively. [1] In vitro, TW-37 shows significant anti-proliferative and pro-apoptotic effect in a de novo chemo-resistant WSU-DLCL2 lymphoma cell line and primary cells obtained from a lymphoma patient without effects on normal peripheral blood lymphocytes. [1] TW-37 exhibits the inhibitory effect on both cell growth and cell death in endothelial cell with IC50 of approximately 1.8 μM without effect on the fibroblasts exposed to the same concentration range as the endothelial cells. In addition, TW37 also shows the anti-proliferation effects in MCF-7, LNCaP, and SLK tumor cell lines with the same or lower concentration range than those required to inhibit endothelial cell growth. [2]
体内活性	TW-37 shows a maximum tolerated dose (MTD) of 40 mg/kg for three i.v. injections in severe combined immunodeficient (SCID) mice when given alone, and enhances tumor inhibitory effect of cyclophosphamide-doxorubicin-vincristine-prednisone (CHOP) regimen. [1] TW-37, administrated by i.v. produces the antiangiogenic effect by decreasing the density of functional human microvessels in the severe combined immunodeficient mouse model of human angiogenesis. [2] The combination of TW-37 and MEK inhibitors synergistically block melanoma cell growth in mice by a significant reduction in tumor volume and tumor mass. [3]
激酶实验	Fluorescence polarization-based binding assay for recombinant Bcl-2, Bcl-XL, and Mcl-1 protein : For this assay, the 21-residue BH3 peptide QEDIIRNIARHLAQVGDSMDR derived from Bid labeled with 6-carboxyfluorescein succinimidyl ester (FAM-Bid) and recombinant proteins derived from human Bcl-2,Bcl-X L,and Mcl-1 are employed. It is determined that FAM-Bid has a Ki of 11 nM to Bcl-2 protein,25 nM to Bcl-XL protein,and 5.7 nM to Mcl-1 protein. The competitive binding assay for Bcl-XL is same as that for Bcl-2 with the following exceptions: 30 nM Bcl-XL protein and 2.5 nM FAM-Bid peptide in the following assay buffer [50 mM Tris-Bis (pH 7.4) and 0.01% bovine gamma-globulin].
细胞实验	The sulforhodamine B (SRB) cytotoxicity assay is used as described. Briefly, optimal cell density for cytotoxicity assay is determined by growth curve analysis. HDMECs are seeded in a 96-well plate and allowed to adhere overnight. Drug or control is diluted in EGM2-MV and layered onto cells, which are allowed to incubate for times as indicated in the figures. Alternatively, HDMECs are coincubated with TW37 and 0 to 100 ng/mL recombinant human VEGF (rhVEGF)165 or 0 to 100 ng/mL recombinant human CXCL8. Cells are fixed on the plates by addition of cold trichloroacetic acid (10% final concentration) and incubation for 1 hour at 4 °C. Cellular protein is stained by addition of 0.4% SRB in 1% acetic acid and incubation at room temperature for 30 minutes. Unbound SRB is removed by washing with 1% acetic acid and the plates are air dried. Bound SRB is resolubilized in 10 mM unbuffered Tris-base and absorbance is determined on a microplate reader at 560 nm. Test results are normalized against initial plating density and drug-free controls. Data are obtained from triplicate wells per condition and are representative of at least three independent experiments(Only for Reference)

体内实验配液计算器

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。
