产品描述 | Piritrexim (BW 301U) is an orally available fat-soluble dihydrofolate reductase inhibitor with pulmonary toxicity used in the study of uroepithelial carcinoma and metastatic breast cancer. |

体外活性 | Piritrexim (0.1 to 1.0 microM) was able to inhibit the replication of T.gondii in a mouse peritoneal macrophage model. The addition of sulfadiazine, which alone was ineffective, to piritrexim allowed inhibition of T.gondii replication at lower concentrations of piritrexim than when piritrexim was used alone.[5] |
体内活性 |
Piritrexim (25-mg/m2/dose; oral) occurred the myelosuppression and mucositis in 4 of 4 patients but in none of the patients treated at the 15- and 20-mg/m2/dose levels.[6] Piritrexim (20 mg/m2/dose; oral) was rapidly absorbed, with the median time to peak level occurring 1.5 h after an oral dose, and the area under the concentration-time curve (AUC) was linearly related to the dose administered. Trough plasma piritrexim concentration strongly correlated with DLT (P = 0.0016). A trough plasma piritrexim concentration greater than 0.5 microM appeared to be predictive of toxicity. Eleven of 15 patients with trough concentrations exceeding this threshold experienced DLTs.[6] |

对于不同动物的给药剂量换算,您也可以参考 更多...
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。
