Target	LTD4 and LTE4[1]
In Vivo	SR2640 inhibits the LTD 4-induced contractions of guinea-pig ileum in a concentration-dependent manner, with an IC50 of 3 nM[1]. SR2640 (1 mg/kg; IV; single dosage) specifically prevents the contractile responses of guinea-pig ileum and trachea to LTD4 and LTE4[1]. Animal Model: Guinea pigs (injected with LTD4 and LTE4)[1] Dosage: 1 mg/kg Administration: IV; single dosage Result: Specifically prevented the contractile responses of guinea-pig ileum and trachea to LTD4 and LTE4.
