The present invention provides methods for preventing or treating disorders associated with the degradation of cholesterol and bile alcohols through the use of ligands that interact with pregnane X receptors (PXR). In a preferred embodiment, PXR agonists are used to treat disorders associated with sterol 27-hydroxylase (CYP27) deficiency or mutation. The disorders associated with CYP27 deficiency include but not limited to cerebrotendinous xanthomatosis, cataracts, gallstone, tendon xanthomas, atherosclerosis, hepatomegaly, hypertriglyceridemia, and neurological and neuropsychiatric abnormalities such as peripheral neuropathy and dementia. In another preferred embodiment, PXR agonists are used to prevent or treat disorders that can be alleviated by enhancing the degradation of cholesterol or bile alcohols. The disorders that can be alleviated by enhancing the degradation of cholesterol or bile alcohols include, but not limited to, cardiovascular diseases, hypertension, atherosclerosis, dyslipidemia, obesity, hypercholesterolemia, hyperlipidemia, hyperlipoproteinemia, hyperchylomicronemia, hyperbetalipoproteinemia, dysbetalipoproteinemia, hyperprebetalipoproteinemia, mixed hyperlipidemia, cholestasis, cholesterolosis, gallstone, cataracts, and hepatomegaly.
本发明提供了通过使用与孕烷 X 受体(PXR)相互作用的配体来预防或治疗与胆固醇和胆汁醇降解相关的疾病的方法。在一个优选的实施方案中,PXR 激动剂用于治疗与甾醇 27- 羟化酶(CYP27)缺乏或突变相关的疾病。与 CYP27 缺乏有关的疾病包括但不限于脑腱黄瘤病、白内障、胆石症、肌腱黄瘤、动脉粥样硬化、肝肿大、高甘油三酯血症以及神经和神经精神异常,如周围神经病变和痴呆。在另一个优选的实施方案中,PXR 激动剂用于预防或治疗可通过促进胆固醇或胆汁醇降解来缓解的疾病。可通过促进胆固醇或胆汁醇降解来缓解的疾病包括但不限于心血管疾病、高血压、动脉粥样硬化、血脂异常、肥胖、高胆固醇血症、高血脂症、高胆固醇血症、高胆固醇血症、高胆固醇血症、高胆固醇血症、高胆固醇血症、高胆固醇血症、高胆固醇血症、高胆固醇血症、高胆固醇血症、高胆固醇血症、高脂血症、高脂蛋白血症、高胆固醇血症、高脂蛋白血症、高脂蛋白血症、高脂蛋白血症、高前脂蛋白血症、混合型高脂血症、胆汁淤积症、胆石症、白内障和肝肿大。
