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 .

HSR6071, a pyrazinecarboxamide derivative, is an orally active and potent antiallergic agent. HSR6071 potently inhibits the experimental asthma in rat models .

DS 4574 is an orally active peptidoleukotriene receptor antagonist and mast cell stabilizer. DS 4574 has antiulcer, gastroprotective and antisecretory effects. DS 4574 inhibits various types of experimental asthma models. DS 4574 protects rats from endotoxin-induced intestinal injury .
