Animal experiment: | Mice[2]The Mrp4-/- mice are used. Concerning the PH reversal study, 5-week-old WT mice are maintained in hypoxia for 3 weeks, then are randomized to receive, for 2 weeks, oral vehicle or MK-571 at the doses of either 5 mg/kg/d or 25 mg/kg/d. At the same time, the experiment is designed for mice in normoxia conditions. Increased hematocrit valuesare checked to assess the efficiency of hypoxia[2]. |

| 产品描述 | MK571 sodium salt is a specific CysLT1 (Cysteinyl-Leukotriene Type 1 Receptor) antagonist [1]. Cysteinyl leukotriene receptor 1, also termed as CYSLTR1, is a receptor for cysteinyl leukotrienes (LT)which mediates a large variety of allergic and hypersensitivity reactions in humans [2]. In vitro: MK571 is a multidrug resistance protein-2 (ABCC2, Mrp2) inhibitor and had been widely used to demonstrate the role of Mrp2 in the cellular efflux of drugs, xenobiotics and their conjugates. Apically-applied MK571 resulted in significant reductions in both the apical and basolateral efflux of flavonol conjugates from Caco-2/TC7 monolayers. The estimated Ki for inhibition of the synthesis of K-4′-O-GlcA by MK571 is 19.7 μM. MK571 inhibited the intracellular biosynthesis of all flavonol glucuronides and sulphates by Caco-2 cells in a dose-dependent manner. MK571 significantly inhibited phase-2 conjugation of kaempferol by cell-free extracts of Caco-2, and competitively inhibited the production of kaempferol-4′-O-glucuronide. These data indicated that MK571, in addition to inhibiting MRP2, was a potential inhibitor of enterocyte phase-2 conjugation [3]. References: |
