  • Patent number: 10568882
    Abstract: 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.
