| ln Vitro |
Aspoxicillin is a semi-synthetic derivative of penicillin [2]. In vitro, Aspoxicillin has a 1.7-hour post-antibiotic effect (PAE) on Staphylococcus aureus Smith.
|
|---|---|
| ln Vivo |
For 5.2 hours, apocillin produced PAE against S. aureus Smith in vivo in a thigh infection model in neutropenic mice [2].
After intravenously injecting hydroxychloroquine (5 mg/kg) into BALB/c mice, the amount of chlorotoquine (desethylhydroxychloroquine) in the mice's blood and tissues was measured. Tissue-to-blood concentration ratio (Kp) ≥1 signifies tissue accumulation of chlorotoquine. From high to low, the following tissues had the highest chlorotoquine Kp ratios: liver (114.3), kidney (24.4), spleen (19.3), lung (16.5), heart (5.5) [3].

| Additional Infomation |
Aspoxicillin is a peptide.
Aspoxicillin is a broad-spectrum, semisynthetic penicillin derivative with antibacterial activity. Aspoxicillin binds to and inactivates penicillin-binding proteins (PBPs) located on the inner membrane of the bacterial cell wall. Inactivation of PBPs interferes with the cross-linkage of peptidoglycan chains necessary for bacterial cell wall strength and rigidity. This interrupts bacterial cell wall synthesis and results in the weakening of the bacterial cell wall, eventually causing cell lysis. |

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
Calculation results
Working concentration： mg/mL；
Method for preparing DMSO stock solution： mg drug pre-dissolved in μL DMSO (stock solution concentration mg/mL). Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug.
Method for preparing in vivo formulation:：Take μL DMSO stock solution, next add μL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O，mix and clarify.
(1) Please be sure that the solution is clear before the addition of next solvent. Dissolution methods like vortex, ultrasound or warming and heat may be used to aid dissolving.
(2) Be sure to add the solvent(s) in order.
