H1 Receptor Agonists (5):

Cat. No. Product Name Effect Purity
  • HY-17043
    Loratadine
    		Agonist 99.98%
    Loratadine (SCH-29851) is a selective inverse peripheral histamine H1-receptor agonist with an IC50 of >32 μM. Loratadine has anti-dengue-virus (DENV) activity. Loratadine can inhibit immunologic release of inflammatory mediators.
  • HY-101052
    HTMT dimaleate
    		Agonist 99.55%
    HTMT (dimaleate) is a potent histamine H1 and H2 receptor agonist. HTMT (dimaleate) is 4 x 104 times more active than histamine in H2-mediated effects in natural suppressor cells.
  • HY-167897
    UR-AK49
    		Agonist
    UR-AK49 (compound 11) is a human histamine H1 and H2 receptor agonist. UR-AK49 has an EC50 of 23 nM in a GTPase assay with hH2R-Gsalpha fusion protein expressed in Sf9 insect cells. UR-AK49 can be used in neuro-related research.
  • HY-B2178
    Emedastine difumarate
    		Agonist
    Emedastine difumarate is an orally active, selective and high affinity histamine H1 receptor antagonist with a Ki value of 1.3 nM. Emedastine difumarate is a benzimidazole derivative with potent antiallergic properties and used for allergic rhinitis, allergic skin diseases and allergic conjunctivitis.
  • HY-12752
    Alimemazine
    		Agonist
    Alimemazine is a phenothiazine derivative that is generally used as an antipruritic agent and also a hemagglutinin (HA)-receptor antagonist.Alimemazine (Trimeprazine) is also acts as a partial agonist against the histamine H1 receptor (H1R) and other GPCRs. Alimemazine displays antiserotonin, antispasmodic, and antiemetic properties.
