生物活性

产品描述 Rifampin (Rifampicin)是DNA依赖性的RNA聚合酶抑制剂,用于治疗许多细菌感染案例。
靶点
RNA polymerase [1]
体外研究

Rifampicin抑制IκBα降解和mitogen活化蛋白激酶(MAPK)磷酸化。Rifampicin以Rifampicin和MD-2浓度依赖性结合人的MD-2。在蓝色的hTLR4的293细胞和免疫microgial BV-2细胞中,Rifampicin以剂量依赖的方式抑制LPS(20 ng/mL)诱导的NF-κB活化,IC 50为44.1 μM。Rifampicin(50 μM)在不同的LPS的剂量抑制NF-κB活化,促进LPS诱导的NF-κB水平的最大化。在BV-2细胞中,Rifampicin抑制LPS (200 ng/mL)诱导的NO的产生,IC 50为21.2 μM。在胶质BV-2和RAW264.7巨噬细胞中,Rifampicin抑制LPS诱导的TNF-α和IL-1β的产生。Rifampicin抑制先天免疫信号是不依赖于孕烷X受体NR1I2的。[1] Rifampicin结合聚酯血管prostheses(PVP)官能化cyclodextrin (PVP-CD)导致细菌粘附显著减少以及对革兰氏阳性菌的生长抑制。[2] Rifampicin(50 μg/mL)显著降低固定相培养物的CFU计数,并减少对数相培养的CFU计数到零。Rifampicin特别合适,因为它是杀菌并开始作用的一个小时内杀死M. tuberculosis。[3]
