体外活性 | Trimethoprim lactate 通过抑制二氢叶酸还原酶(DHFR)活性来干扰叶酸代谢,从而阻止二氢叶酸向四氢叶酸(THF)的还原。在大肠杆菌细胞中,Trimethoprim lactate 引起蛋白质聚集并诱导主要的热休克蛋白(Hsps),表明其存在会导致蛋白质错误折叠。Trimethoprim lactate 可诱导热休克蛋白 DnaK、DnaJ、GroEL、ClpB 和 IbpA/B 的表达,其中 IbpA/B 的诱导最为显著,并与不溶性蛋白质共聚集。[1] |
体内活性 | 在小鼠腹腔感染试验中,Trimethoprim lactate 对流感嗜血杆菌、肺炎链球菌、大肠杆菌和脑膜炎奈瑟菌的CD50值分别为150mg/kg、335mg/kg、27.5mg/kg和8.4mg/kg。Trimethoprim lactate 与硫代麦芽糖(TM-TMP)结合后,在完全血清中保持稳定,半衰期约为1小时,对大肠杆菌的MIC约为 1 μM[2]。 |
