PCSK9 degrader 1 (Compound 16) is a small molecule ligand for proprotein convertase substilisin-like/kexin type 9 (PCSK9) and shows high affinity to PCSK9 with a Ki of 107 nM. PCSK9 degrader 1 can involve in a protein-protein interaction with the low-density lipoprotein (LDL) receptor.
PCSK9 degrader 1 (Compound 16; 1.25-20 μM; 24 hours; HEK293 cells) treatment shows a clear concentration-dependent degradation of both the pro and mature form of PCSK9 yielding a half-maximal degradation concentration of 4.8 and 3.4 μM, as well as a maximum percentage of degradation at 20 μM of 58% and 61%, respectively[1].
