| Antibacterial experiment [1]: | |
|
Bacteria |
Gram-positive and Gram-negative bacteria |
|
Preparation method |
The solubility of this compound in DMSO is > 23.9 mg/mL. General tips for obtaining a higher concentration: Please warm the tube at 37 °C for 10 minutes and/or shake it in the ultrasonic bath for a while. Stock solution can be stored below - 20 °C for several months. |
|
Reacting condition |
12.5 ~ > 100 μM |
|
Applications |
Zafirlukast exhibited antibacterial and antibiofilm activities against Gram-positive bacteria (including the cariogenic pathogen S. mutans) whilst showed no significant activity against Gram-negative bacteria (except for the oral pathogen P. gingivalis). Additional tests showed that Zafirlukast did not cause resistance in S. mutans. |
| Animal experiment [2]: | |
|
Animal models |
A rat model of colitis |
|
Dosage form |
40 or 80 mg/kg; orally or rectally; for 3 consecutive days |
|
Applications |
In a rat model of colitis, pretreatment with Zafirlukast (80 mg/kg, orally) significantly decreased tissue malondialdehyde and myeloperoxidase, and meanwhile, increased the reduced glutathione and catalase levels, whilst there was no significant change when it was given rectally. At the dose of 40 mg/kg dose (orally and rectally), no significant protective effect was observed. |
|
Other notes |
Please test the solubility of all compounds indoor, and the actual solubility may slightly differ with the theoretical value. This is caused by an experimental system error and it is normal. |
