Neospiramycin I is a macrolide antibiotic and derivative of spiramycin I.1 It is active against the macrolide-sensitive KB210, but not the macrolide-resistant KB224, strain of S. aureus (MICs = 3.12 and >100 µg/ml, respectively), as well as B. cereus, B. subtilis, M. luteus, E. coli, and K. pneumoniae (MICs = 1.56, 3.12, 3.12, 0.2, 50, and 12.5 µg/ml, respectively). Neospiramycin I binds to E. coli ribosomes with an IC50 value of 1.2 µM. It protects against mortality in a mouse model of S. pneumoniae type III infection (ED50 = 399.8 mg/kg).2

计算结果:
工作液浓度： mg/ml；
DMSO母液配制方法： mg 药物溶于 μL DMSO溶液（母液浓度 mg/mL，
体内配方配制方法：取 μL DMSO母液，加入 μL PEG300，混匀澄清后加入μL Tween 80，混匀澄清后加入 μL saline，混匀澄清。
1. 首先保证母液是澄清的；
2.
一定要按照顺序依次将溶剂加入，进行下一步操作之前必须保证上一步操作得到的是澄清的溶液，可采用涡旋、超声或水浴加热等物理方法助溶。
