ProtocolIn VitroOral administration of Asapiprant to sheep at 1 and 3 mg/kg significantly (P<0.01) suppresses the increase in nasal resistance by 82% and 92%, respectively. Oral administration of Asapiprant to sheep at 5 mg/kg suppresses Prostaglandin (PG) D2 (PGD)2-induced nasal resistance by 86%. When orally administered 1 h before the antigen challenge in pigs, Asapiprant (3, 10, and 30 mg/kg) suppresses immediate airway response (IAR) by 52%, 57%, and 96%, and late airway response (LAR) by 67%, 50%, and 79%, respectively. Orally administered with Asapiprant (5 mg/kg) for 4 days, the Asapiprant significantly (P<0.01) suppresses antigen-induced nasal resistance by 73% in sheep. Treatment with 3 and 30 mg/kg of Asapiprant in pigs significantly (P<0.01) suppresses nasal secretion by 53% and 72%, respectively. Treatment with Asapiprant in rats at 10 mg/kg significantly (P<0.05) reduces airway hyper-responsiveness (AHR), infiltration of inflammatory cells, and mucin production in bronchoalveolar lavage fluid (BALF), although treatment with Asapiprant at 0.1 mg/kg does not have a significant effect on any responses.

Working concentration: mg/ml;
Method for preparing DMSO master liquid: mg drug pre-dissolved in µL DMSO(Master liquid 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 master liquid, next add µL PEG300, mix and clarify, next add µL Tween 80,mix and clarify, next add µL ddH2O,mix and clarify.
Note:
  • (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.
