[Uses]

Tipelukast a novel oral anti-inflammatory agent, suppresses bladder hyperactivity in a rat model.
[Definition]

ChEBI: Tipelukast is an aromatic ketone.
[Biological Activity]

Tipelukast is a Leukotriene D4 (LTD4) receptor antagonist and an inhibitor of 5-lipoxygenase (5-LO) and also phosphodiesterases PDE3 and PDE4. It has been found to have antifibrotic and anti-inflammatory activity. Tipelukast has been investigated as a possible treatment for nonalcoholic fatty liver disease (NAFLD) and nonalcoholic steatohepatitis (NASH).
[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].
