Biological Activity |
Tedizolid是一种恶唑烷酮类抗生素,具有抗革兰氏阳性菌的活性。[1] |
In Vitro |
Tedizolid(以前称为torezolid,TR-700或DA-7157,商品名Sivextro)是一种恶唑烷酮类抗生素,可抵抗革兰氏阳性细菌。作用机理是通过与G +细菌的50S核糖体亚基结合来抑制蛋白质合成。Tedizolid phosphate是前体药物tedizolid phosphate(TR-701)的活性部分,具有拮抗革兰氏阳性菌的活性。Tedizolid在体外拮抗PRSP的效力是linezolid的4倍多[1]。 |
In Vivo |
Tedizolid具有良好的肺上皮黏液层渗透性。通过口服途径或静脉注射给药,Tedizolid phosphate在体内可有效地拮抗系统性感染。口服Tedizolid phosphate还可有效拮抗由PSSP菌株所诱导的肺炎[1]。对于用PSSP III型感染的小鼠,使用最低总日剂量10mg / kg的tedizolid磷酸盐实现100%存活率。用tedizolid磷酸盐治疗的感染小鼠的肺显示出较少的严重炎症和水肿,如炎症和水肿的平均评分所示[2]。 |
Animal Experiment |
为了诱导全身性肺炎链球菌感染,将雄性ICR小鼠(体重18至20g)腹膜内接种悬浮于10%粘蛋白中的4种PRSP分离物(DR9,DR10,DR11或DR14)中的1种。悬浮液含有足够的细菌以杀死100%未处理的对照小鼠。在感染后1小时,小鼠接受单剂量的Tedizolid Phosphate或利奈唑胺,并且在感染后每天评估存活7天。以四种剂量(40mg / kg体重,13.33mg / kg,4.44mg / kg和1.48mg / kg)中的每一种口服和静脉内递送治疗,每组8只小鼠由剂量,递送方法定义,并感染菌株。使用概率单位分析计算每种递送途径的50%有效剂量(ED50),即允许50%感染小鼠存活的剂量。[2] |
