Technical Field

[0002] This invention belongs to the field of drug synthesis, specifically relating to a nitrogen-containing heterocyclic derivative inhibitor, its preparation method, and its application. Background Technology

[0003] Cardiovascular disease (CVD) is a leading cause of death worldwide, and high levels of low-density lipoprotein cholesterol (LDL-C) are a major risk factor. The accumulation of LDL-C on the arterial walls leads to atherosclerosis and can trigger inflammatory responses, resulting in cardiovascular events such as heart attacks and strokes. Although statins can lower serum LDL-C and are currently the main lipid-lowering drugs in clinical practice, patients who are intolerant to statins or who fail to reach their treatment goals when receiving tolerated doses still face risks, such as patients with familial hypercholesterolemia. The discovery of PCSK9 inhibitors provides a more aggressive treatment option for homozygous and heterozygous familial hypercholesterolemia. The non-statin ezetimibe, when used in combination with statins, can lower LDL-C by 15%-20%, while PCSK9 inhibitors combined with statins can significantly lower LDL-C by 54%-74%. PCSK9 inhibitors can also overcome the intolerable side effects of statins, such as muscle pain.

[0004] PCSK9 (Proprotein convertase subtilisin kexin type 9) is a serine protease highly expressed in the liver. Loss-of-function mutations in the PCSK9 gene are associated with low LDL-C levels and reduced cardiovascular risk (Cohen, JC, 2006), and it has been clinically validated as a therapeutic target for hyperlipidemia. PCSK9 is synthesized as an enzyme precursor, and after synthesis, it undergoes autocatalytic cleavage within the cell. The propeptide binds to mature PCSK9 and is secreted extracellularly, thus blocking the catalytic activity of PCSK9.

[0005] PCSK9 is a major regulator of low-density lipoprotein receptor (LDLR) levels on the surface of hepatocytes and can inhibit the LDLR circulation pathway. LDLR function is crucial for maintaining cholesterol homeostasis, responsible for the uptake and degradation of low-density lipoprotein. Circulating LDL binds to the N-terminal ligand-binding domain of LDLR via apolipoprotein B100. The LDL / LDLR complex is internalized through receptor-mediated endocytosis. The low intracellular pH environment causes LDLR to release LDL, which then circulates back to the cell membrane. Intracellular free LDL is transported to lysosomes and degraded. Secreted PCSK9 interferes with LDLR circulation by binding to LDLR on the hepatocyte surface. After the PCSK9 / LDLR complex migrates through clathrin-encapsulated pits into the acidic endosomal chamber, a conformational change in LDLR leads to the formation of additional binding sites with PCSK9. Therefore, PCSK9 accompanies LDLR to lysosomes for degradation, preventing LDLR circulation and thus upregulating LDL-C levels.

[0006] Familial hypercholesterolemia (FH) is a hereditary disorder of low-density lipoprotein cholesterol metabolism, affecting 1 in 250 people, characterized by significantly elevated LDL-c levels. Heterozygous FH patients have a 3-4 times higher risk of developing coronary artery disease (CAD) and often develop CAD an average of 10 years earlier than the general population. Statins lower LDL-C in heterozygous FH patients; in Besselin's study, high-intensity statin therapy was shown to reduce CAD risk and mortality by 44%. However, in many cases, the reduction in LDL-C is considered insufficient. The complementarity mechanism of statins involves upregulating sterol regulatory element-binding protein 2 (SREBP-2), thereby activating LDL receptors and PCSK9, increasing PCSK9 expression and secretion binding to LDLR, leading to elevated LDL-C levels in the blood. Therefore, while statins lower LDL by inhibiting HMGCoA, they counteract the effects of SREBP; adding a PCSK9 inhibitor to statin therapy can help overcome this mechanism. Considering that patients with familial hypercholesterolemia may not fully benefit from statin therapy, alternative treatments such as PCSK9 inhibitors are needed.

[0007] PCSK9 macromolecule inhibitors, such as the monoclonal antibody-based drugs Alirocumab and Evolocumab, selectively bind to extracellular PCSK9 and prevent its interaction with LDLR. They have been approved by the FDA for lowering LDL-C levels with a good safety profile. Studies have shown that in heterozygous FH patients who have not reached their LDL-C target after statin monotherapy, once-every-two-week injections of Alirocumab maximally reduce cardiovascular risk. Alirocumab has also shown a moderate increase in "good" cholesterol (HDL-C). Additionally, the PCSK9 siRNA drug Inclisiran is currently marketed; it lowers PCSK9 protein expression levels for long-term lipid reduction with a good safety profile. However, both of these drugs require injection and are expensive to produce. Currently, there are no marketed PCSK9 small molecule inhibitors, therefore there is a high demand for oral PCSK9 small molecule inhibitors.

[0008] There are already patent reports on PCSK9 small molecule inhibitors, such as WO2014170786 (Pfizer), WO2014150326 (Shifa), WO2020150473 (AZ), and WO2022133529 (Nyrada). Currently, AZD-0780, which is the most advanced, is in Phase I clinical trials, while the others are in preclinical development. Several peptides have also been reported, with the most advanced being in Phase II clinical trials. This invention aims to develop an orally administered PCSK9 small molecule inhibitor.
