Mequitamium iodide
Synonym(s): LG 30435
- CAS No.: 101396-42-3
- Formula:C21H25IN2S
- Molecular Weight:464.41
IUPAC Name: 3-((10H-phenothiazin-10-yl)methyl)-1-methylquinuclidin-1-ium iodide
InChIKey: SWVANDLDSRKJFI-UHFFFAOYSA-M
SMILES: C[N+]1(CC2)CC(CN3C4=C(C=CC=C4)SC5=CC=CC=C35)C2CC1.[I-]
Biological Activity: Mequitamium iodide (LG 30435) is an antihistamine drug with antiallergic and bronchodilatory activity. Mequitamium iodide can effectively antagonize airway contraction and inflammatory responses induced by histamine and antigens. Mequitamium iodide has nanomolar affinity for the H1 and smooth muscle receptors of histamine and mequitin. Mequitamium iodide, when administered in aerosol form, significantly inhibits histamine- and antigen-induced increases in airway pressure in allergic mice. Mequitamium iodide reduces antigen-induced eosinophil accumulation in the airways. Mequitamium iodide also exhibits inhibitory effects on PAF-induced platelet aggregation and bronchoconstriction, and can be used in the study of allergic diseases such as rhinitis and asthma[1].
