Zafirlukast is a potent orally active leukotriene D4 (LTD4) receptor antagonist.
Zafirlukast is a peptidyl leukotriene antagonist and inhibitor of LTD4. After 13 weeks of exposure, the yield of lung tumors is significantly decreased by both dose levels of Zafirlukast (270 and 540 mg/kg), the high dose of Zileuton (1200 mg/kg), and the combinations containing 600 mg/kg Zileuton with either Zafirlukast or MK-866. The efficacy of the combination containing Zileuton and Zafirlukast to prevent lung tumors is not significantly different from the efficacy of either inhibitor administered alone. Although when administered alone at the dose level in their combination, neither Zileuton or MK-886 prevents lung tumors; the combination containing them does significantly prevent tumors. In contrast, the combination containing Zafirlukast and MK-886 does not reduce the yield of tumors, whereas Zafirlukast administered alone does significantly reduce the yield of tumors[2].

| 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. |

| General tips | Please select the appropriate solvent to prepare the stock solution according to the
solubility of the product in different solvents; once the solution is prepared, please store it in
separate packages to avoid product failure caused by repeated freezing and thawing.Storage method
and period of the stock solution: When stored at -80°C, please use it within 6 months; when stored
at -20°C, please use it within 1 month. To increase solubility, heat the tube to 37°C and then oscillate in an ultrasonic bath for some time. |
