Biological Activity
Azatadine (3.4 nM-13 nM; 3 minutes) competitively inhibits Histamine (HY-B1204)-induced contractions in isolated guinea-pig ileum segments with an ED50 of 6.5 nM[1].
Azatadine (6.8 nM-27 nM; 3 minutes) competitively inhibits acetylcholine-induced contractions in isolated guinea-pig ileum segments with an ED50 of 10 nM[1].
Azatadine (6.8 nM-27 nM; 3 minutes) inhibits Serotonin (HY-B1473A)-induced contractions in isolated unprimed virgin rat uterus segments with an ED50 of 14 nM[1].
Azatadine (50 μM-1 mM) dose-dependently inhibits anti-IgE-induced Histamine and Leukotriene C4 (HY-113446) release from human lung mast cells, with significantly greater inhibition of Leukotriene C4 release (85% at 1 mM) compared to histamine release (45% at 1 mM)[3].
