SR2640

(Synonyms: QMPB)

SR2640 is a highly efficient and selective LTD4/LTE4 antagonist that can specifically inhibit the smooth muscle contractions induced by LTD4 in the guinea pig ileum and trachea in a concentration-dependent manner, without affecting the contractions caused by histamine. SR2640 can concentration-dependently prevent the binding of 0.4 nM [3H] LTD4 to membrane receptors in guinea pig lung tissue, with an IC₅₀ of 23 nM. SR2640 can shift the dose-response curve for bronchoconstriction induced by intravenous LTD4 in guinea pigs to the right, and the extent of this shift is positively correlated with the dose of SR2640 administered. SR2640 can be used in asthma research.

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
