The mechanism by which PCSK9 influences cholesterol levels is well-established.MK-0616: The 2023 Molecule of the Year PCSK9 binds to LDL receptors on the surface of liver cells, marking them for degradation within the cell.Spotlight on PCSK9 peptide vaccines This process reduces the number of LDL receptors available to clear LDL-C from the bloodstream, leading to elevated plasma LDL-C levels. Consequently, PCSK9 is a highly attractive biological target for LDL-C reduction.

Traditionally, therapies targeting PCSK9 have involved monoclonal antibodies or small interfering RNAs (siRNAs) requiring injection. However, the field is rapidly shifting towards more convenient and potentially more effective modalities, with a strong focus on peptide-based inhibitors作者：C Alleyne·2020·被引用次数：122—Proprotein convertase subtilisin-like/kexin type 9 (PCSK9) is a key regulator of plasma LDL-cholesterol (LDL-C) and a clinically validated .... These peptides are designed to interfere with the interaction between PCSK9 and the LDL receptor (LDLR).

A significant breakthrough in this area is the development of orally bioavailable macrocyclic peptide inhibitors作者：DG Johns·2023·被引用次数：127—Macrocyclicpeptidesrepresent a novel approach to target proteins traditionally considered intractable to small-molecule drug design.. Enlicitide is a novel small molecule macrocyclic peptide that specifically binds to PCSK9, thereby inhibiting its interaction with LDL receptors. This approach offers a paradigm shift from injectable therapies to an oral administration route, significantly enhancing patient convenience. Enlicitide decanoate, an oral macrocyclic peptide, is being evaluated for its efficacy in treating hypercholesterolemia. Early studies suggest that Enlicitide decanoate, an oral macrocyclic peptide that inhibits PCSK9 binding to LDL receptors, reduced LDL cholesterol levels in short-term trials. Furthermore, Enlicitide is a novel small molecule macrocyclic peptide candidate that aims to offer a new therapeutic option.

Beyond macrocyclic peptides, other peptide-based strategies are also being explored. For instance, research into peptide vaccines against PCSK9 has shown promise in pre-clinical models. Studies have indicated that mice vaccinated with VLP-PCSK9 peptide vaccines developed high titers of IgG antibodies against PCSK9, suggesting an immunotherapeutic approach to PCSK9 inhibition. Another area of investigation involves developing specific PCSK9-peptide sequences that can disrupt the PCSK9-LDLR interactionSeries of Novel and Highly Potent Cyclic Peptide PCSK9 .... One such example is a PCSK9-peptide comprising 12 amino acids derived from specific regions of the PCSK9 protein, aiming for a long-lasting therapeutic effect.

The scientific community continues to delve into the intricacies of PCSK9 function and its regulation. Research has explored how mutations or modifications within the PCSK9 protein can affect its activity and interaction with LDL receptors. For example, studies have investigated the impact of Leu22_Leu23 duplication at the signal peptide of PCSK9, suggesting that PCSK9 may reduce LDLr levels by an intracellular mechanism, associated with an impaired SP cleavage.作者：BJ Tombling·2021·被引用次数：38—This review surveys thecurrent peptide-based landscape aimed towards PCSK9 inhibition, covering pre-clinical to patented drug candidates.
