| Description | Tipelukast (KCA 757) is a novel, orally available leukotriene receptor antagonist with anti-inflammatory properties, capable of reducing fibrosis and down-regulating TIMP-1 and type 1 collagen. Tipelukast is utilized in asthma research. |
| Targets&IC50 | LTD4:6.41 (pA2,guinea-pigs), LTE4:6.45 (pA2,guinea-pigs), LTD4 receptor:2.3 μmol (pulmonary cell membrane) |
| In vitro | Tipelukast inhibits the binding of [3H] LTD4 to the LTD4 receptors on the pulmonary cell membrane of guinea-pigs (IC50 = 2.3 μmol)[1]. |
| In vivo | Fifteen minutes after an aerosolized antigen challenge, and inhaled 5 minutes later into the guinea pigs, Tipelukast significantly modifies the bronchoconstriction induced by UNDW[1]. Intravenous administration of Tipelukast (1 and 5 mg/kg) 15 minutes after antigen challenge dose-dependently reduces propranolol-induced bronchoconstriction (PIB) in guinea-pigs[1]. |
