SR2640 - CAS 105350-26-3

SR2640 is a potent and highly selective LTD4/LTE4 antagonist, specifically inhibiting LTD4-induced contractions in guinea pig ileum and tracheal smooth muscle in a concentration-dependent manner, without affecting histamine-induced contractions. It blocks the binding of 0.4 nM [3H]LTD4 to guinea pig lung membrane receptors with an IC50 of 23 nM. SR2640 also causes a parallel rightward shift in the dose-response curve for LTD4-induced bronchoconstriction in guinea pigs when administered intravenously, with the degree of shift correlating positively with its dosage. SR2640 is applicable for asthma research.
