产品描述 Pretomanid ((S)-PA 824) , a nitroimidazole, is used as an anti-tuberculosis drug for tuberculosis with MIC less than 2.8 μM.
靶点活性 MTB pan-sensitive and rifampin mono-resistant clinical isolates:0.015-0.25 ug/ml
体外活性 In vitro, PA-824 exhibits the high activity against multidrug-resistant Clinicalal isolates from Asia (India and South Korea) and from throughout the United States (MIC < 1 μg/ml) and is equally active against the drug-sensitive and multidrug-resistant isolates of M. tuberculosis (MICs range, 0.039 to 0.531 μg/ml). [1] A recent study shows that single-nucleotide polymorphisms of PA-824 resistance genes (fgd1 [Rv0407] and ddn [Rv3547]) don't significantly affect the PA-824 MICs (≤ 0.25 μg/ml). [2]
体内活性 In the rapid tuberculosis mouse model, PA-824 shows significant anti-microbial activity in a dose-dependent manner: at 50 mg/kg, PA-824 in MC produces a more than 1-log reduction of the CFU in the lungs; at 100 mg/kg it produces about a 2-log reduction, and at 300 mg/kg it produces a 3-log reduction. Furthermore, long-term treatment of PA-824 at 100 mg/kg in cyclodextrin/lecithin also leads to the reduction of the bacterial load below 500 CFU in the lungs and spleen. [1] PA-824 exhibits time-dependent anti-microbial activity in a murine model of tuberculosis with a maximal observed bactericidal effect of 0.1 log CFU/day over 24 days. [3]
激酶实验 Isolated kinase assays: The intracellular kinase domains of human EGFR and erbB2 are cloned and expressed in the baculovirus/Sf21 system. The inhibitory activity of AZD8931 is determined with ATP at Km concentrations (0.4 mM for erbB2 and 2 mM for EGFR) using the ELISA method.
细胞实验 A method is used to determine the MICs by a microdilution plate assay by using M. tuberculosis H37Rv. INH is dissolved in sterile, double-distilled water at a stock concentration of 500 μg/ml. PA-824 is dissolved in 100% dimethyl sulfoxide (DMSO) to a stock concentration of 100 μg/ml. A 1:2 dilution series of both compounds is made in a separate 96-well microtiter plate by using the same diluents. The interior 60 wells of a 96-well round-bottom microtiter assay plate are seeded with 98 μl of bacterial suspension. Two microliters of each drug is transferred to the assay plate wells containing bacteria. The final concentrations of INH in the wells range from 10.0 to 0.039 μg/mL; the final concentrations of PA-824 range from 2.0 μg/mL to 8.0 pg/mL. The assay plates are incubated at 37 °C for at least 21 days and are observed every 3 to 4 days to evaluate changes in growth. Inhibition of growth is determined both by visual examination and with a spectrophotometer at an OD600.(Only for Reference)

TargetMol Calculator 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。
