Introduction of 125961-82-2 :

Tipelukast (KCA 757) is a sulfidopeptide leukotriene receptor antagonist, an orally bioavailable anti-inflammatory agent and used for the treatment of asthma. In Vitro: Tipelukast inhibits the binding of [3H] LTD4 to the LTD4 receptors on pul-monary cell membrane of guinea-pigs (IC50 = 2.3 μmol)[2]. In Vivo: Fiftheen min after an aerosolized antigen challenge, and UNDW inhaled 5 min later into the guinea pigs, Tipelukast significantly alters the UNDW-induced bronchoconstriction[1]. Tipelukast (1 and 5 mg/kg) administered intravenously 15 min after antigen challenge reduces the propranolol-induced bronchoconstriction (PIB) in a dose-dependent manner in guinea-pigs[2].
