Chemical Structure
Tazanolast
Synonym(s): TO 188; Tazalest; Tazanol
- CAS No.: 82989-25-1
- Formula:C13H15N5O3
- Molecular Weight:289.29
IUPAC Name: butyl 2-((3-(1H-tetrazol-5-yl)phenyl)amino)-2-oxoacetate
InChIKey: XQTARQNQIVVBRX-UHFFFAOYSA-N
SMILES: O=C(OCCCC)C(NC1=CC=CC(C2=NN=NN2)=C1)=O
Biological Activity: Tazanolast (TO 188) is an orally active selective mast cell stabilizer. Tazanolast prevents the elevation of intracellular calcium concentration, inhibits calcium uptake and Protein kinase C translocation, without directly inhibiting phospholipase C. Tazanolast inhibits ozone-induced airway hyperresponsiveness to Methacholine in guinea pigs, as well as passive cutaneous anaphylaxis, Schultz-Dale reaction, experimental asthma, passive cutaneous anaphylaxis in rats, and increased cutaneous vascular permeability in rats. Tazanolast does not alter airway responsiveness in sham-exposed guinea pigs, cell distribution in bronchoalveolar lavage fluid after ozone exposure, type II-IV allergic reactions, or histamine release from atopic leukocytes. Tazanolast can be used in research related to allergic diseases[1][2].
