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核受体激动剂以前已被证明可以增加胆固醇外流,提高血浆高密度脂蛋白胆固醇,刺激胆固醇排泄和减少动脉粥样硬化斑块。然而,这些激动剂也与不良的高三酰甘油血症副作用相关。这种高三酰甘油血症似乎是由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有吸引力的候选药物。本申请提供了新的LXRβ选择性配体,它们更倾向于调节LXRβ而不是LXRα。这些配体可以用于治疗与LXR相关的各种疾病,例如脂质代谢紊乱、动脉粥样硬化、阿尔茨海默病和炎症。
