This invention is related to the field of PCSK9 biology and the composition and methods of use of small organic compounds as ligands for modulation of PCSK9 biological activity. In particular, the invention provides compositions of small organic compounds that modulate circulating levels of low density lipoproteins by altering the conformation of the protein PCSK9. Binding these small organic compound ligands to PCSK9 alters the conformation of the protein, modifying the interaction between PCSK9 and an endogenous low density lipoprotein receptor, and can lead to reduced or increased levels of circulating LDL-cholesterol. High LDL-cholesterol levels are associated with increased risk for heart disease. Low LDL-cholesterol levels may be problematic in other conditions, such as liver dysfunction; thus, there is also utility for small organic compound ligands that can raise LDL levels.
本发明涉及 PCSK9 生物学领域以及小分子有机化合物作为配体用于调节 PCSK9 生物活性的组合物和使用方法。特别是,本发明提供了通过改变蛋白质 PCSK9 的构象来调节低密度脂蛋白循环水平的小分子有机化合物组合物。将这些小分子有机化合物配体与 PCSK9 结合可改变该蛋白的构象,改变 PCSK9 与内源性低密度脂蛋白受体之间的相互作用,并可导致循环中低密度脂蛋白胆固醇水平的降低或升高。低密度脂蛋白胆固醇水平高与心脏病风险增加有关。低密度脂蛋白胆固醇水平低可能会对肝功能障碍等其他疾病造成困扰;因此,能提高低密度脂蛋白水平的小分子有机化合物配体也很有用。
