生物活性

Metioprim is a competitive inhibitor of bacterial Dihydrofolate reductase (DHFR). Metioprim has inhibitory activity against anaerobic bacteria. Metioprim shows synergistic activity in combination with DDS (HY-B0688) against E. coli. and various mycobacteria[1][2].

体外研究
(In Vitro)

Metioprim 对部分厌氧菌有抑制作用,平均 MIC 值为 3.2 μg/mL[1]
Metioprim (0-1.0 μM;0-8 h) 抑制细菌生长动力学,抑制大肠杆菌的 MIC 值为 0.7 μg/mL[2]

体内研究
(In Vivo)

Metioprim (5 mg/kg or 10 mg/kg; 静脉注射; 单剂量) 在羊中的消除半衰期比猪的短 (23 min vs 169 min),它的主要代谢产物为蛋氨酸亚砜和甲氧磷磺酸[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.
