Pap12-6是一种从蝶类P. xuthus幼虫中发现的papiliocin十二个N-端氨基酸衍生的抗菌肽。它对包括E. coli、P. aeruginosa和S. syphimurium在内的八种革兰氏阴性细菌(MIC50s = 4-8 µM)以及革兰氏阳性细菌S. aureus、耐甲氧西林的S. aureus 3126(MRSA-3126)、B. subtilis和S. epidermidis(MIC50s = 4-8 µM)具有活性,但在25 µM浓度下不影响人类红细胞、小鼠RAW 264.7巨噬细胞、人类HaCaT角质形成细胞或人类HEK293肾细胞的活性。Pap12-6在4和8 µM浓度下可引起E. coli的膜去极化。Pap12-6(10 µM)预处理可降低LPS刺激的RAW 264.7巨噬细胞中一氧化氮(NO2-)、Tnf-α和Il-6的分泌水平。在体内,Pap12-6(10 mg/kg)可以提高感染E. coli的小鼠的存活率,并且在剂量为1 mg/kg时减少感染E. coli小鼠的肺、肝和肾中菌落形成单位(CFUs)的数量。Pap12-6(1 mg/kg)在E. coli诱导的败血症小鼠模型中降低血清天门冬氨酸转氨酶(AST)和丙氨酸转氨酶(ALT)水平及血尿素氮水平。

产品描述 | Pap12-6, an antibacterial peptide originating from the first twelve N-terminal amino acids of papiliocin found in P. xuthus larvae, exhibits activity against a range of eight Gram-negative bacteria (e.g., E. coli, P. aeruginosa, S. syphimurium with MIC50s=4-8 µM) and Gram-positive bacteria (e.g., S. aureus, methicillin-resistant S. aureus 3126, B. subtilis, and S. epidermidis with MIC50s=4-8 µM), without compromising the viability of human erythrocytes, mouse RAW 264.7 macrophages, human HaCaT keratinocytes, or human HEK293 kidney cells at 25 µM. It causes membrane depolarization in E. coli at 4 and 8 µM and, upon preincubation at 10 µM, decreases nitrite (NO2-), Tnf-α, and Il-6 secretion in LPS-stimulated RAW 264.7 macrophages. In a murine model, Pap12-6 enhances survival rates and diminishes colony forming units (CFUs) in several organs upon E. coli infection at 10 mg/kg and 1 mg/kg doses, respectively. Additionally, at a 1 mg/kg dose, it lowers serum aspartate aminotransferase (AST) and alanine transaminase (ALT) levels, as well as blood urea nitrogen levels in E. coli-induced sepsis, indicating its therapeutic potential for bacterial infections without affecting host cell viability. |

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。
