Definitions
- the invention belongs to the field of medicinal chemistry and relates to 8- (2- (difluoromethyl) -6-methylpyridin-4-yl) -7- (2,4-difluorophenyl)-[1,2,4 ] A, B, C, D, E, F, G, H, J, K, L, M, N, O, P crystalline forms of triazolo [4,3-c] pyrimidin-5-amine and preparation thereof method.
- Adenosine is a naturally occurring purine nucleoside and is an endogenous regulator of many physiological functions. It plays an important role in the regulation of the functions of the cardiovascular system, central nervous system, respiratory system, kidneys, fats and platelets.
- adenosine The role of adenosine is mediated by the G protein-coupled receptor family.
- G protein-coupled receptor family At least four subtypes of adenosine receptors are currently known, classified as A1, A2a, A2b, and A3.
- A1 and A3 receptors inhibit the activity of the enzyme adenylate cyclase
- A2a and A2b receptors stimulate the activity of the enzyme, thereby regulating the level of cyclic AMP in cells.
- adenosine regulates a wide range of physiological functions.
- A2a receptor (A2aR) is widely distributed in the body, mainly expressed in the striatum in the central nervous system, and also expressed in peripheral, heart, liver, lung, kidney and other tissues.
- adenosine A2a receptor antagonists have amazing effects on the treatment of neurodegenerative diseases, mainly Parkinson's disease, Huntington's disease or Alzheimer's disease (Trends in Neurosci. 2006, 29 (11), 647 -654; Expert Opinion on Therapeutic Patents, 2007, 17, 979-991, etc.). It can also be used to treat other central nervous system (CNS) related diseases such as depression, hyperactivity syndrome, sleep disorders and anxiety (Clin. Neuropharmacol. 2010, 33, 55-60; J. Neurosci.
- CNS central nervous system
- adenosine A2a receptor antagonists also have therapeutic potential as neuroprotective agents (see Jenner P. J. Neurol 2000. 24; 7Supp 12: 1143-50).
- A2a receptors can play an important role in immunological regulation during ischemic hypoxia, inflammation, trauma, transplantation and many other pathological processes, which may be related to A2a receptors in T cells, B cells, and single cells. Nuclear macrophages, neutrophils and other immune cells have higher expression levels.
- the activation of A2a receptors can promote the body's immune tolerance, and is closely involved in the formation of tumor cells' "escape” or "immunosuppression", creating favorable conditions for the development of tumors. Lokshin and colleagues (Cancer Res.
- A2a receptor antagonists can also be used in the treatment of tumors.
- adenosine A1 receptor when adenosine A1 receptor is in tissue ischemia / hypoxia, in the central, circulatory, digestive system, and skeletal muscle, when cells are in a hypoxic and hypoxic stress environment, extracellularly aggregated adenosine activates the cell through The A1 receptor on the membrane activates the corresponding protective mechanism, thereby increasing the tolerance of cells to hypoxia and hypoxia.
- the A1 receptor on immune cells can promote cellular immune response in a hypoxic environment.
- the A1 receptor can reduce free fatty acids and triglycerides and participate in regulating blood sugar.
- Adenosine receptor A3 (as described by Gessi et al., Pharmacol. Ther.
- A3 receptor Continuous blockade may increase the likelihood of complications caused by any pre-existing or developing ischemic heart disease, such as angina pectoris or heart failure.
- the crystalline form as a medicinal active ingredient often affects the chemical stability of the drug. Differences in crystallization conditions and storage conditions may cause changes in the crystalline structure of the compound, sometimes accompanied by the generation of other forms.
