Anti-inflammatory, membrane-stabilizing interactions of salmeterol with human neutrophils in vitro.

abstract：BACKGROUND AND PURPOSE:Pyrazole derivatives have recently been suggested as selective blockers of transient receptor potential cation (TRPC) channels but their ability to distinguish between the TRPC and Orai pore complexes is ill-defined. This study was designed to characterize a series of pyrazole derivatives in term...
