[0006] The entire contents of said prior application are incorporated herein by reference. Technical Field
[0007] The present application belongs to the field of medicine, and specifically relates to a spirocyclic alkene or azaalkene compound and its pharmaceutical composition, preparation method and use, which can be used as a complement factor B inhibitor. Background Art
[0008] Complement is a class of soluble pattern-recognition molecules in the immune system that can perform a variety of effector functions. Under natural conditions, complement components exist as inactive zymogens. Various specific and nonspecific immunological mechanisms break down these inactive zymogens, producing active large and small fragments. Large fragments typically remain on the surface of pathogens or cells, causing their lysis or accelerating their clearance; small fragments leave the cell surface and mediate various inflammatory responses. Complement activation consists of two closely related processes, forming a cascade of complement activation reactions. Currently, there are three main known complement activation pathways: the classical pathway, the lectin pathway, and the alternative pathway. Although the three complement activation pathways differ in their initiation mechanisms and activation sequence, they share a common terminal pathway. Activation of the alternative pathway is independent of antigen-antibody complexes. Typically, C3b deposited on the cell surface binds to factor B, becoming susceptible to breakdown by factor D in the serum. During this process, factor B is broken down into Ba and Bb. C3b and Bb then form a complex to form the C3 convertase C3bBb in the alternative pathway. In this process, complement factor B plays an early and central role in activation of the alternative pathway of the complement cascade. C3b is both a product of C3 convertase's breakdown of C3 and a component of the alternative pathway's C3 convertase, forming a feedback amplification mechanism in which the classical and alternative pathways interact. Current research has linked a variety of diseases, including hematologic, autoimmune, inflammatory, and neurodegenerative, to dysfunctional complement systems.
[0009] Paroxysmal nocturnal hemoglobinuria (PNH) is a chronic disease with persistent hemolysis. It is caused by a non-malignant clonal disease caused by acquired somatic PIG-A gene mutations in one or more hematopoietic stem cells. It is an ultra-rare blood disease (Medicine (Baltimore) 1997, 76(2): 63-93). The course of the disease can be manifested by varying degrees of hemolysis (paroxysmal), chronic or recurrent acute intravascular hemolysis or subsequent venous / arterial thrombosis, ultimately leading to progressive end-organ damage and death. It is a typical PNH with chronic intravascular hemolysis, hemoglobinuria and hemosiderinuria as the main manifestations. However, most patients are often atypical, with insidious onset, prolonged course, and varying severity.
[0010] There are over ten proteins on the surface of red blood cells that inhibit complement pathway activation. These proteins are all anchored to the cell membrane via glycosylated phosphatidylinositol (GPI) and are collectively referred to as GPI-anchored proteins (APs). It is currently believed that the pathogenesis of PNH begins with the mutation of hematopoietic stem cells under certain conditions, resulting in the generation of GPI-deficient PNH clones. Subsequently, due to factors (mostly believed to be immune), hematopoietic impairment or failure occurs, allowing PNH clones to gain a proliferative advantage over normal clones. The presence of multiple GPI-linked antigens complicates the interpretation of PNH cell biological behavior. Among these, the most important inhibitors of complement pathway activation, CD55 (a decay-accelerating factor for protein C3 convertase) and CD59 (a membrane attack complex (MAC) inhibitor), are closely linked to the pathogenesis, clinical manifestations, diagnosis, and treatment of PNH (Frontiers in Immunology 2019, 10, 1157). CD59 prevents the incorporation of C9 into the C5b-8 complex, thereby preventing the formation of the membrane attack unit and inhibiting the terminal complement attack response. The hallmark manifestations of PNH—intravascular hemolysis and thrombosis—are currently believed to be due to CD59 deficiency. Patients with congenital CD59 deficiency have been reported to exhibit many of the hallmark symptoms of PNH, such as intravascular hemolysis, hemoglobinuria, and venous thrombosis. In PNH patients, defective GPI synthesis prevents CD59 from binding to the red blood cell membrane, resulting in its inability to inhibit complement pathway activation. Consequently, aberrant complement activation occurs, attacking red blood cells and leading to multiple clinical manifestations, including intravascular hemolysis, hemoglobinuria, and smooth muscle dysfunction. Currently, there is no effective cure for PNH other than hematopoietic stem cell transplantation to restore normal hematopoiesis. Due to the risks associated with hematopoietic stem cell transplantation and the fact that PNH is a benign clonal disorder, controlling hemolytic episodes remains the mainstay of clinical treatment. Currently, only eculizumab is approved for the treatment of PNH. However, many patients continue to experience anemia despite eculizumab treatment, and many require ongoing blood transfusions. In addition, eculizumab requires intravenous administration. Therefore, the development of new inhibitors of the complement pathway for the treatment of PNH is of great significance.
[0011] IgAN is the most common primary glomerulonephritis, characterized by immunofluorescence-detected IgA deposits in the mesangium. Clinical manifestations vary, typically presenting with recurrent microscopic or gross hematuria. Existing data suggest that the development of IgAN is associated with innate or acquired immune dysregulation. IgA1 production is increased in the mucosa due to irritation of the respiratory or digestive tract by viruses, bacteria, and food proteins, or immune complexes containing IgA1 are deposited in the mesangium, activating the alternative complement pathway and causing glomerular damage. Human IgA molecules are divided into two subtypes: IgA1 and IgA2. IgA1 is the predominant form circulating in healthy individuals (comprising approximately 85%) and is the primary component of mesangial deposits in patients with IgAN. IgA molecules can exist as both monomers and multimers. IgA1 molecules possess a unique heavy chain hinge region between the first and second constant regions, which serves as the site for the attachment of O-linked glycan groups. Recent studies have found that the IgA molecules deposited in the serum and glomerular mesangium of IgAN patients are primarily glycosylation-deficient IgA1 (gd-IgA1). It is currently believed that the initiation of IgAN pathogenesis is the abnormal increase in gd-IgA1 production.
[0012] More than 90% of IgAN patients have deposits of complement C3 in the glomerular mesangium. 75%-100% of IgAN patients have co-depositions of properdin, IgA, and C3 in the renal tissue, and 30%-90% of IgAN patients have co-depositions of complement factor H, IgA, and C3 in the renal tissue. In addition to deposits in renal tissue, some studies have found that the levels of complement alternative pathway markers in the plasma of IgAN patients are also related to the activity of IgAN (J Nephrol 2013, 26(4):708-715). Studies have confirmed that C3a in renal tissue and urine, as well as C3a receptors in renal tissue, are significantly correlated with the activity and severity of renal damage (J clin Immunol 2014, 34(2):224-232). Other studies have confirmed that IgA can activate the complement alternative pathway under in vitro conditions. In this process, abnormalities in the hinge region of IgA do not play a decisive role, but the formation of IgA multimers is the key link (Eur J Immunol 1987, 17(3): 321-326). Currently, the deposition of complement C3 in the glomerular mesangium has become an auxiliary diagnostic marker for IgAN. A study performed C3c and C3d immunofluorescence detection on the renal tissues of 163 IgAN patients. The results showed that IgAN patients with higher C3c deposition intensity than C3d deposition intensity showed lower glomerular filtration rate, higher incidence of glomerular capillary hyperplasia, and more severe hematuria, indicating that glomerular C3c deposition is related to the active lesions of IgAN (Am J Nephrol. 2000, 20(2): 122-128). Currently, there is no specific drug to treat IgAN in clinical practice. The main drugs used are general-purpose renin-angiotensin inhibitors (ACEI or ARB), glucocorticoids, and various immunosuppressants. In addition, the safety of this type of drug is also an issue that cannot be ignored. For example, although glucocorticoids have the effect of reducing proteinuria, the STOP-IgAN trial and the TESTING-I trial clearly confirmed the potential side effects of glucocorticoids (IgA nephropathy 2019, 95, 4, 750-756).
[0013] Arthritis is a common chronic inflammatory disease caused by inflammation, infection, degeneration, trauma, or other factors. Clinical manifestations include joint redness, swelling, heat, pain, dysfunction, and deformity. These symptoms often result in severe pain, limited mobility, and physical deformity. In severe cases, they can lead to disability, significantly impacting patients' quality of life. Studies have shown that K / BxN mouse serum does not induce arthritis in mice deficient in complement factor B, whereas wild-type mice develop arthritis in response to K / BxN mouse serum (Immunity, 2002, 16, 157–168). This suggests that the complement system plays a crucial role in the pathogenesis of K / BxN mouse serum-induced arthritis and that complement factor B is a potential therapeutic target for arthritis.
[0014] The small molecule complement factor B inhibitors developed by Novartis AG are used to treat diseases such as age-related macular degeneration (AMD). Related patents include: WO2013164802A1, WO2013192345A1, WO2014143638A1, WO2015009616A1, WO2015066241A1 and WO2019043609A1.
[0015] Inflammatory and immune-related diseases are diverse and difficult to cure. There are unmet clinical needs in these areas, and new small molecule drugs need to be developed for medical treatment.
