一般說明

化学结构:大环内酯

應用

红霉素是一种抗生素,是通过 红霉素链霉菌的某些菌株的生长而产生的。 该产品主要由红霉素A和少量红霉素B和C组成,推荐浓度为100 mg/L。 50至200mg/L的浓度范围也被证明可有效控制细菌的生长。 红霉素已被用作胃动素受体激动剂,以在体外阻断人气道中的呼吸糖结合物分泌, 并可用于质粒固化重组乳酸链球菌MG1363菌株的选择。

生化/生理作用

作用机制: 红霉素通过在转肽步骤中抑制延伸起作用,特别是通过结合细菌70S rRNA复合物的50S亚单位来抑制氨酰从A位点到P位点的易位。

抗菌谱:该产品可以抗革兰氏阴性和革兰氏阳性细菌。

注意

该产品在37℃下在溶液中可保持稳定3天。 储备溶液应储存在2-8℃。

準備報告

该产品可以2mg/mL的浓度溶于水中,0.067%的水溶液的pH值为8.0-10.5。 它也可以50mg/mL的浓度溶于乙醇中,获得澄清、无色至淡黄色的溶液。 它易溶于醇、丙酮、氯仿、乙腈和乙酸乙酯中,但会与酸形成盐。 所有溶液应保证避光。
