Cell experiment: |
Zoliflodacin broth macrodilution MICs are determined and used as the starting point for both in vitro time-kill and postantibiotic-effect (PAE) tests. In vitro static time-kill studies are conducted with glass tubes (18 by 150 mm, without agitation) containing 10-mL volumes of cation-adjusted Mueller-Hinton broth with logarithmically growing cultures (starting inoculum of 1×106 CFU/mL) against levofloxacin-susceptible and levofloxacin-resistant S. aureus. Zoliflodacin is tested at concentrations equivalent to 0.5, 1, 2, 4, and 8 times the MIC; samples are plated for colony counts at 0, 2, 4, 6, 8, and 24 h by using 100 μL aliquots spotted onto 25-ml sheep blood agar plates as described previously. Compounds are considered bactericidal at the lowest drug concentration that reduced viable organism counts by ≥3 log10 in 24 h. Time-kill studies are conducted in duplicate; tests are combined, and mean values are reported[1]. |

Zoliflodacin (ETX0914;AZD0914) is a novel spiropyrimidinetrione bacterial DNA gyrase/topoisomerase inhibitor. Zoliflodacin has potent in vitro antibacterial activity against Gram-positive and Gram-negative organisms, including S. aureus with the MIC90 of 0.25 ug/mL.
Zoliflodacin has antibacterial activity against key Gram-positive (Staphylococcus aureus, Staphylococcus epidermidis, Streptococcus pneumoniae, Streptococcus pyogenes, and Streptococcus agalactiae), fastidious Gram-negative (Haemophilus influenzae, Neisseria gonorrhoeae), atypical (Legionella pneumophila), and anaerobic (Clostridium difficile) bacterial species, including isolates with known resistance to fluoroquinolones. The antibacterial activity of Zoliflodacin is shown to be via inhibition of DNA biosynthesis and accumulation of double-strand cleavages; this mechanism of action differs from those of other marketed antibacterial compounds, including fluoroquinolones. Zoliflodacin stabilizes and arrests the cleaved covalent complex of gyrase with double-strand broken DNA under permissive conditions and thus blocks religation of the double-strand cleaved DNA to form fused circular DNA[1].

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。
