Biochem/physiol Actions
Inhibits the assembly of DNA and protein into mature virus particles.
Mode of Action: Inhibits initiation of RNA synthesis by binding to β-subunit of RNA polymerase.
Rifampicin inhibits the assembly of DNA and protein into mature virus particles. It inhibits initiation of RNA synthesis by binding to β-subunit of RNA polymerase, which results in cell death1.

Application
Rifampicin is used to treat Tuberculosis and Tuberculosis-related mycobacterial infections1. It is widely used as an antipruritic agent in the autoimmune cholestatic liver disease, primary biliary cirrhosis (PBC). It has been shown to cause hepatitis.

其他名称:利发霉素;甲哌利福霉素;力复平;利米定;3-[[(4-甲基-1-哌嗪基)亚氨基]甲基]-利福霉素;利福霉素SV;甲哌力复霉素;3-(4-甲基-1-哌嗪亚胺甲基)利福霉素;利福定


级别:植物组培试剂
含量:≥99.0%
PH:4.5~6.5

性状:红棕色或棕红色结晶粉末。干燥粉末可稳定5年以上,微溶于水,其水溶液在室温10h失效,但加入还原剂(如抗环血酸)可减少分解,在二甲亚砜中极稳定
用途:生化研究。对结核杆菌和其他分枝杆菌,革兰氏阳性和革兰氏阴性菌均有很强的杀菌作用。抑制DNA的重组和蛋白质插进成熟的病毒颗粒。靠结合RNA聚合酶的β-亚单元抑制RNA合成的起始。从利福霉素B得到的一种半合成抗生素。能抑制细菌DNA转录合成RNA,可用于治疗结核病、肠球菌感染等。除作为抗生素应用外,在分子生物学中可用做从细菌中去除质粒的试剂。
