Paromomycin Sulfate (Aminosidine sulfate) 是一种广谱氨基糖苷类抗生素 ,是具有杀螨杀菌作用的新霉素衍生物。它通过与细菌 30S 核糖体 A 位点的 RNA 寡核苷酸特异性结合,使 mRNA 的翻译提前终止,并抑制蛋白质合成。它可研究细菌和寄生虫感染。
产品描述 | Paromomycin binds specifically to the RNA oligonucleotide at the A site of bacterial 30S ribosomes, thereby causing misreading and premature termination of translation of mRNA and inhibition of protein synthesis followed by cell death. Paromomycin Sulfate (Aminosidine sulfate) is the sulfate salt form of paromomycin, a structural derivative of neomycin, an aminoglycoside antibiotic with amebicidal and bactericidal effects against predominantly aerobic gram-negative bacteria. |
体外活性 | 在CL临床病例和实验模型中,用paromomycin药膏涂抹L. major造成的损伤比L. panamensis和L. amazonensis造成的恢复的更快、更彻底. |
体内活性 | 作为一种氨基糖苷类抗生素,Paromomycin对许多革兰氏阳性菌、革兰氏阴性菌、一些原生动物和绦虫均显示出较强的抗菌活性。小鼠巨噬细胞模型中无鞭毛体敏感度的体外分析表明,L. tropica和菌系L. major(ED50s:1~5 μM) 比L. mexicana (ED50:39 μM) 和L. braziliensis (ED50:<12 μM) 菌系对Paromomycin更敏感。菌系L. donovani中度敏感(ED50:6~18 μM),除了一个Indian菌株,DD8,其ED50 >150 μM。 |
激酶实验 | Concentration–response and kinetic studies: The microsomal protein (30 μg), [1β-3H]androstenedione (6.6 × 105 dpm) and NADPH (270 μM) are used for the concentration–response experiment with an incubation time of 20 minutes. The Aminoglutethimide is initially tested at 10 μM and 100 μM concentrations, followed by a full concentration–response study with at least 8 concentrations ranging from 0.01 μM to 160 μM. For the initial velocity study the concentration of [1β-3H]androstenedione is varied from 7.5 to 100 nM and the incubation time is set to 5 minutes. The tritiated water formed during the conversion of the tritiated substrate, [1β-3H]androstenedione, to estrone is quantified by liquid scintillation counting. Each assay is performed three times in duplicate and the results are treated by nonlinear regression analysis allowing the determination of the half-maximal inhibitory concentration (IC50). |

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。
