In particular, the disclosure relates to tetrahydropyridopyrimidinedione derivatives represented by general formula (I), a preparation method thereof, pharmaceutical compositions containing the derivatives, and uses of the derivatives as therapeutic agents, especially uses as Myosin (Myosin) inhibitors and uses in preparation of drugs for treating Hypertrophic Cardiomyopathy (HCM) or heart diseases with pathophysiological characteristics related to HCM.
Description
Technical Field
The disclosure belongs to the field of medicines, and relates to a tetrahydropyridopyrimidinedione derivative, a preparation method thereof and application thereof in medicines. In particular, the disclosure relates to tetrahydropyridopyrimidinedione derivatives represented by general formula (I), a preparation method thereof, pharmaceutical compositions containing the derivatives, and uses thereof as Myosin (Myosin) inhibitors and in preparation of drugs for treating Hypertrophic Cardiomyopathy (HCM) or heart diseases with pathophysiological characteristics related to HCM.
Background
Hypertrophic Cardiomyopathy (HCM) is a dominant hereditary myocardial disease associated with genetic mutations. The global incidence is about 0.2%, which is the most important cause of sudden death in young people under 35 years old (C. Vaughan Tuohy, et al, European Journal of Heart Failure,22,2020, 228-. Clinically, it is characterized by the asymmetrical hypertrophy of left ventricular wall, frequent invasion and ventricular septum, small ventricular cavity, obstruction of left ventricular blood filling, and decreased ventricular diastolic compliance. The disease is classified into obstructive and non-obstructive hypertrophic cardiomyopathy according to the presence or absence of obstruction in the left ventricular outflow tract. At present, beta-blockers and calcium channel blockers are mostly adopted for clinically treating hypertrophic cardiomyopathy to reduce cardiac contraction and relieve symptoms. However, these treatments are all palliative and not root-cause. HCM progression to late stages is only amenable to heart transplantation (R adhakrishnan Ramaraj, Cardiology in Review,16(4),2008, 172-. Therefore, it is very urgent to find a treatment method aiming at the pathogenesis source of HCM.
The present study found that 70% of HCM patients are caused by mutations in the sarcomere gene. Multiple site mutations are found in 5-7% of patients. More than about 70 pathogenic mutations have been identified, but most of these mutations are family-specific, with only a few hot spots identified, such as the MYH 7R 403Q and R453C mutations (Norbert Frey, et al, Nature Reviews biology, 9,2011, 91-100; m.sabater-Molina, et al, Clinical Genetics,93,2018, 3-14). Research aiming at the pathogenic probability of gene mutation finds that MYH7 gene mutation patients account for about 30%. MYH7 causes early onset of disease and more severe myocardial hypertrophy compared to other sarcomere genes. Myosin is a constituent unit of the thick myofilaments of myofibrils and plays an important role in muscle movement. The molecular shape is like bean sprout, and is composed of two heavy chains and a plurality of light chains. The myosin head combines with actin to form a transverse bridge, so that the ATPase activity of myosin is greatly improved, ATP hydrolysis reaction is catalyzed, energy is generated to promote the transverse bridge to slide, and muscle contraction is carried out. The results of the studies indicate that mutation in the MYH7 gene results in increased myosin ATPase activity, decreased myosin super-delayed State (SRX) ratio, and increased cross-bridging between myosin and actin, leading to abnormal systolic function (Eric M.Green, et al, Science,351(6273),2016, 617-. Myosin is therefore an important target for the treatment of hypertrophic cardiomyopathy.
Patent applications for myosin inhibitors have been disclosed including, inter alia, WO2014205223A1, WO2014205234A1, WO2019028360A1, WO2020092208A1 and CN 110698415A.
