Definitions

  • Triazolopyrimidine derivatives preparation methods thereof and uses thereof
  • the present invention relates to a novel triazolopyrimidine derivative, a pharmaceutical composition containing the same, a process for the preparation thereof and use thereof as a therapeutic agent, particularly as a P2Y12 receptor antagonist. Background technique
  • Signal transduction is the process of transmitting extracellular information into cells, participating in various biological regulation processes of cells, enhancing, differentiating, integrating and transmitting the acquired information to downstream sensors to achieve various biological effects processes.
  • Signal transduction is transmitted through membrane surface receptors, which are currently the largest family of membrane surface receptors and are involved in numerous signal transduction processes.
  • G protein-coupled receptors are classified into three classes according to the downstream G-protein types: Gs protein, Gi protein, Gq protein, and G12/13 protein, four G protein subtypes to mediate signaling.
  • G-protein coupled receptors are found only in eukaryotic organisms.
  • Ligands capable of binding to G protein-coupled receptors include information hormones, neurotransmitters, polypeptides, small molecule compounds, and the like.
  • G protein-coupled receptors are involved in the formation of many diseases and are therefore important drug targets. About 30% of the drugs on the market today use G-protein coupled receptors as targets.
  • Gq/Gi-coupled receptors There are numerous subfamilies of Gq/Gi-coupled receptors, including: (1) Purinergic receptors, members including PI, P2; (2) Adenosine receptors, Members include Al, A2A, A2B, A3, which are one of the PI subfamilies of the purine receptor family.
  • the purine receptor family plays a key role in regulating cardiac muscle oxygen consumption, coronary blood flow, anti-inflammatory, vascular reactivity, apoptosis, and cytokine secretion.
  • the P2 subfamily can be further divided into five phenotypes according to pharmacological characteristics and tissue distribution: P2X, P2Y, ⁇ 2 ⁇ , P2U and ⁇ 2 ⁇ . Among them, ⁇ 2 ⁇ and ⁇ 2 ⁇ belong to ion channel type receptors, and P2Y, P2U and ⁇ 2 ⁇ belong to G protein coupled receptors.
  • the ⁇ 2 ⁇ receptor family that has been found to couple G proteins includes nine ( ⁇ 2 ⁇ 1, 2, 4, 6, 11-14) subtypes, which are widely distributed in many cells and tissues, and the subtypes have low homology. Therefore, different subtypes have high selectivity for ligands.
  • ⁇ 2 ⁇ 1, 2, 6, and 14 bind Gq and activate the PLC pathway;
  • P2Y12, 13 binds Gi to inhibit adenylate cyclase activity;
  • P2Y4 couples Gq/Gi two G proteins;
  • P2Y11 couples Gq/Gs two G proteins .
  • the P2Y receptor mediates a range of biological effects including platelet aggregation, immune regulation, and smooth muscle cell proliferation.
  • Thrombosis is formed by platelet aggregation during coagulation. Thrombosis formed in non-injury can reduce blood flow velocity or even block terminal blood vessels, causing tissue necrosis, atherosclerosis, myocardial infarction and other diseases. Platelet activation has multiple pathways and mechanisms such as collagen exposed in blood vessels, tissue factor, endogenous stimulatory factor ADP, and the like.
  • Co-activation of the P2Y1 and P2Y12 receptors is integral to platelet aggregation.
  • the P2Y1 receptor releases Ca 2+ by activating the PBK pathway to cause aggregation of platelet deformation.
  • P2Y1 gene knockout type small Rats do not respond to ADP-induced platelet aggregation and deformation [Fabre JE et al, Nat Med 5: 1199-1202 (1999)].
  • the P2Y12 receptor was first cloned in 2001 [Hollopeter G et al., Nature 409: 202-207 (2001)]. Studies have shown that the P2Y12 receptor is involved in fibrinogen receptor activation, thrombosis, thromboxane A2 production, and platelet aggregation induced by trauma.
  • the human P2Y12 receptor consists of 342 amino acids, mainly distributed in platelets and brain tissue, and is a target for antithrombotic thiophene pyridines.
  • Endogenous stimulating factors such as ADP and other binding to the P2Y12 receptor activate pathways such as PBK and activate Raplb, Akt, and ER pathways to cause activation of fibrinogen receptors in combination with fibrinogen to induce thrombosis or platelet aggregation. This process must be achieved with simultaneous activation of the P2Y1 receptor.
  • the PAR-1 receptor belongs to the G protein-coupled receptor family, and the structural extracellular N-terminal portion is cleaved by serine proteases such as thrombin to activate itself, thereby exerting coagulation.
  • Activation of the Akt pathway activation must also rely on activation of the P2Y12 receptor and amplify the signal through the G12/13 pathway. Blocking the P2Y12 receptor significantly inhibits platelet aggregation and thrombosis induced by ADP and other stimulating factors such as the PAR-1 activating peptide SFLLR, collagen, and the like.
  • P2Y12 receptor antagonists include WO1999005143, WO2000034283, and WO200103642.
