Piperilate  (Synonyms: Pipethanate)

Piperilate (Pipethanate) is one of the mixtures of hetrazepine derivative PAF antagonists with anticholinergics, can be used for bronchial asthma research. Piperilate also causes hypotension and rescues mice poisoned by the organophosphates^[1][2][3].

Piperilate (11.3 mg/kg, 29.42 mg/kg; i.p.; single dose) shows anticholinergic activity, and (30 mg/kg; i.p.; single dose) exerts efficacy in mice poisoned by the organophosphates^[1].
Piperilate (1 mg/kg; i.v.) causes hypotension in rabbit which is not blocked by dichloroisoproterenol or Atropine (HY-B1205)^[2].
Piperilate (3 mg/kg; i.v.) decreases respiration and heart rate of test rabbits, blocks the Adrenaline (HY-122304)-induced constriction of an isolated rabbit auricle preparation^[2].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.
