Progressive familial intrahepatic cholestasis type 2 (PFIC2) is caused by hereditary mutations of bile salt export pump (BSEP), such as E297G BSEP, which is a folding-defective mutant that is unable to traffic beyond the endoplasmic reticulum (ER). 4-Phenylbutyric acid (4-PBA) enhances the cell surface expression and transport capacity of E297G BSEP, but has a relatively high dose (1 mM or more) is
进行性2型家族性肝内胆汁淤积症(PFIC2)是由胆盐输出泵(BSEP)的遗传突变引起的,例如E297G BSEP,这是一种折叠缺陷型突变体,无法运输到内质网(ER)之外。4-苯基丁酸(4-PBA)可以增强E297G BSEP的细胞表面表达和运输能力,但需要相对较高的剂量(1 mM或更高)才能显示效果。在这里,我们表明胆汁酸可能充当药理伴侣,促进E297G BSEP的正确折叠和运输。我们还描述了对E297G BSEP具有强大药理伴侣活性的非甾体化合物的发现和结构开发。
