生物活性

Ranbezolid (RBx7644 free base) is an orally active, oxazolidinone antibiotic against Gram-positive and Gram-negative anaerobes including Staphylococcus aureus, Staphylococcus epidermidis and Bacteroides fragilis. Ranbezolid can inhibit the 50s ribosomal subunit with an IC50 of 17 μM for bacterial ribosomes. Ranbezolid interferes cell wall and lipid synthesis. Ranbezolid can rapidly kill bacteria, significantly reduce bacterial load, and has better cardiovascular safety. Ranbezolid can be used for the study of antibiotics for anaerobic bacteria[1][2][3].

体外研究
(In Vitro)

Ranbezolid (1 μg/mL) 能够强效抑制金黄色葡萄球菌和表皮葡萄球菌蛋白质合成,并且额外抑制表皮葡萄球菌的细胞壁和脂质合成[1]
Ranbezoild (1-8 μg/mL) 能够浓度依赖型引起表皮葡萄球菌的膜损伤[1]
Ranbezoild 对于细菌核糖体的 IC50 值为 17 μM,安全性指数为 865[1]
Ranbezolid 针对脆弱拟杆菌、普通拟杆菌、多形拟杆菌、产气荚膜梭菌、艰难梭菌和马格纳斯菌的最小抑菌浓度 (MIC) 分别为 0.06、0.015、0.06、0.06、0.03 和 0.015 μg/mL[2]

体内研究
(In Vivo)

Ranbezoild (100 mg/kg, p.o., 每日给药 2 次, 共 5 天) 在小鼠异物感染模型中,对脆弱拟杆菌具有出色的体内活性[2]
Ranbezoild (≤ 50 mg/kg, p.o., 单次给药) 在大鼠自发升压模型中不会显著增强 Tyramine (HY-W007606) 引发的升压反应[3]

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
