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. 1. A method , comprising binding an allosteric small molecule compound to a PCSK9 protein to modulate the uptake of low-density lipoprotein by a plurality of hepatocytes.2. A method of claim 1 , to treat liver dysfunction or liver disease.3. A method of claim 2 , wherein said modulation is the increasing uptake of low-density lipoprotein by a plurality of hepatocytes.4. A method of claim 3 , wherein the allosteric small molecule is selected from the group consisting of SRX75 claim 3 , SRX76 claim 3 , SRX204 claim 3 , SRX208 claim 3 , SRX209 claim 3 , SRX210 claim 3 , SRX211 claim 3 , SRX212 claim 3 , SRX 213 claim 3 , SRX214 claim 3 , SRX215 claim 3 , SRX216 claim 3 , SRX217 claim 3 , SRX218 claim 3 , SRX219 claim 3 , SRX220 claim 3 , SRX221 claim 3 , SRX222 claim 3 , SRX223 claim 3 , SRX224 claim 3 , and SRX225.5. A method of claim 3 , wherein said allosteric small molecule compound is further combined with a second pharmaceutical compound.6. A method of claim 2 , wherein said modulation is the decreasing the uptake of low-density lipoprotein by a plurality of hepatocytes.7. A method of claim 6 , wherein the ...
