This invention is related to the field of PCSK9 biology and the composition and methods of use of small molecule ligands for modulation of PCSK9 biological activity. In particular, the invention provides compositions of small molecule compounds that modulate circulating levels of low density lipoproteins by altering the conformation of the protein PCSK9. Binding these small molecule 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 molecule ligands that can raise LDL levels.
这项发明涉及PCSK9生物学领域,以及用于调节PCSK9生物活性的小分子配体的组成和使用方法。具体而言,该发明提供了调节低密度脂蛋白循环水平的小分子化合物组合物,通过改变蛋白质PCSK9的构象来实现。将这些小分子配体与PCSK9结合会改变蛋白质的构象,修改PCSK9与内源性低密度脂蛋白受体之间的相互作用,并可能导致循环LDL胆固醇水平降低或增加。高LDL胆固醇水平与心脏疾病风险增加相关。低LDL胆固醇水平在其他情况下可能会有问题,比如肝功能障碍;因此,开发能够提高LDL水平的小分子配体也具有实用性。
