产品描述 | KPT276 (KPT 276) is an orally bioavailable selective inhibitor of nuclear export (SINE) that irreversibly bind to CRM1 and block the function of CRM1. |
体外活性 | KPT-276 results in significant growth inhibition and apoptosis induction in MCL cells. [2] KPT-276 specifically and irreversibly inhibits the nuclear export function of XPO1, and reduces the viability of 12 HMCLs. KPT-276 also actively induces apoptosis in primary MM patient samples. [3] |
体内活性 | KPT-276 significantly prolongs survival of leukemic mice and reduces leukemic burden in a xenograft AML mouse model. [1] KPT-276 significantly suppresses tumor growth in an MCL-bearing severe combined immunodeficient mouse model without severe toxicity. [2] KPT-276 reduces monoclonal spikes in the Vk*MYC transgenic MM mouse model, and inhibits tumor growth in a xenograft MM mouse model. [3] |
激酶实验 | Kinase inhibition assay: A glutathione S-transferase-tagged kinase domain construct of the intracellular portion of the PDGFR-β (amino acids 693-1401, accession no. J03278) is expressed in Sf-9 cells (baculovirus expression system). Enzyme kinetics are determined by incubating the enzyme with increasing concentrations of ATP in phosphorylation buffer [50 mmol/L HEPES (pH 7.3), 125 mmol/L NaCl, 24 mmol/L MgCl2 in Nunc Immuno MaxiSorp 96-well plates previously coated with 100 μL of 100 μg/mL poly-Glu-Tyr (4:1 ratio) diluted in PBS. After 10 minutes, the plates are washed (PBS, 0.1% Tween 20), incubated with anti-phosphotyrosine-horseradish peroxidase antibody, and diluted in PBS, 0.05% Tween 20, 3% BSA for 30 minutes at room temperature. The plates are washed as above and incubated with 3,3',5,5'-tetramethylbenzidine. The reaction is stopped by adding an equal volume of 0.09 NaH2SO4. The phosphotyrosine-dependent signal is then quantitated on a plate reader at 450 nm. For routine enzyme assays, the enzyme is incubated with 10 μM ( final) ATP in the presence of compound diluted in DMSO (1.6% v/v DMSO assay final) for 30 minutes at room temperature in plates, as above, previously coated with 100 μL of 6.25 μg/mL poly-Glu-Tyr. The remainder of the assay is carried out as above, and IC50 values are calculated as percent inhibition of control. |

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。
