Framycetin is an aminoglycoside antibiotic and it also inhibits hammerhead ribozyme (Ki: 13.5 μM). 在相同实验条件下,摩尔浓度相同的化合物盐形式与游离态具有相同的生物活性,但盐形式 Framycetin sulfate 的水溶性和稳定性通常比游离态更好。

体外活性 | Neomycin B targets the bacterial and human ribosomes and affects translation. Neomycin B is used clinically to treat hepatic encephalopathy (by reducing ammonium levels in the gut) and enteropathogenic Escherichia coli infections. The addition of neomycin B, to an HCC cell line, selectively inhibits the production of the mature miRNA, boosts a downstream protein, and inhibits invasion [2]. The aminoglycoside antibiotic neomycin B causes misreading of the genetic code during translation and inhibits several ribozymes. The ribosomal target site of neomycin B is the 16 S rRNA 1400 to 1500 region, which has been clearly demonstrated by dissecting this domain from a small RNA of 27 nucleotides. This small subdomain of the 16 S rRNA is protected from chemical modification by neomycin at the same positions as in the context of the 30 S subunit [4]. Neomycin B interacts with various target RNAs that have no primary sequence homology. This means that the drug binds to a structural rather than a sequence motif of the RNA. Its primary cognate target is the decoding site of the 16S rRNA, but it also binds to the Rev-responsive element in HIV-1, a group I introns, and the hammerhead ribozyme, and thus inhibits their biological function [3]. |

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。
