    Product Description

    PF-3716556 is a potent and selective hydrogen-potassium pump (H+/K+-ATPase) inhibitor in a new class of acid suppressants, the potassium-competitive acid blockers or acid pump antagonists.1 PF-3716556 inhibited H+/K+-ATPase activity in porcine membrane vesicles, as well as canine and human recombinant cells under ion-leaky conditions (pIC50s = 6.026, 6.038, and 6.009, respectively). PF-3716556 showed 3-fold greater inhibition than revaprazan in ion-tight (neutral pH) conditions.

    WARNING This product is not for human or veterinary use.
