SUN-1334H free base is a potent orally active inhibitor of the histamine H1 receptor, demonstrating an IC50 of 20.3 nM and a Ki value of 9.7 nM. This compound effectively inhibits histamine-induced contractions in isolated guinea-pig ileum with an IC50 of 0.198 μM. SUN-1334H free base has significant applications in research related to bronchoconstriction, allergic responses, and rhinitis, as evident in its ability to mitigate histamine-induced bronchoconstriction in guinea pigs, skin wheals in beagle dogs, and ovalbumin-induced rhinitis in guinea pigs.
