产品描述
MK571 sodium salt是特异性CysLT1(半胱氨酰-白三烯1型受体)拮抗剂[1]。
半胱氨酰白三烯受体1简称为CYSLTR1,是半胱氨酰白三烯(LT)的受体,在人体内介导多种过敏和超敏反应[2]。
体外实验:MK571是多药耐药蛋白-2(ABCC2,Mrp2)抑制剂,被广泛用于证明Mrp2在药物、异生素及其共轭物的细胞外排中的作用。顶端施用MK571显著减少来自Caco-2/TC7单层的黄酮醇缀合物的顶端和基底外侧流出。MK571抑制K-4'-O-GlcA合成的估算的Ki为19.7 μM。MK571以剂量依赖性方式抑制Caco-2细胞所有黄酮醇葡糖苷酸和硫酸盐的细胞内生物合成。MK571显著抑制Caco-2的无细胞提取物中kaempferol的2相共轭,并竞争性抑制kaempferol-4′-O-glucuronide的生成。这些数据表明MK571除了抑制MRP2之外,还是肠上皮细胞2相共轭的潜在抑制剂[3]。
