LXR nuclear receptor agonists have been previously shown to increase cholesterol efflux, raise plasma HDL cholesterol, stimulate cholesterol excretion, and reduce atherosclerotic lesions. However, these agonists have also been associated with the unwanted side effect of hypertriglyeridemia. This hypertriglyeridemia appears to be mediated by the LXRα subtype rather than LXRβ, which suggests that LXRβ-selective agonists are attractive candidates for modulation of human lipid metabolism. The present application provides novel LXRβ-selective ligands that preferably modulate LXRβ over LXRα. These ligands may be used to treat a variety of diseases associated with LXR, such as for example lipid metabolism disorders, atherosclerosis, Alzheimer disease, and inflammation.
LXR核受体激动剂先前已被证明可以增加
胆固醇外流,提高血浆HDL
胆固醇,刺激
胆固醇排泄,并减少动脉粥样硬化病变。然而,这些激动剂也与不良的副作用高三酸
甘油脂血症有关。这种高三酸
甘油脂血症似乎是由LXRα亚型介导的,而不是LXRβ,这表明LXRβ选择性激动剂是调节人类脂质代谢的理想候选药物。本申请提供了新颖的LXRβ选择性
配体,优先调节LXRβ而非LXRα。这些
配体可用于治疗与LXR相关的多种疾病,例如脂质代谢紊乱、动脉粥样硬化、阿尔茨海默病和炎症。
