Definitions
- the present disclosure relates to the field of medicine, and in particular to an antagonist of MAS-related G protein receptor X2 (MRGPRX2), a composition comprising the antagonist, and a preparation method thereof.
- MRGPRX2 MAS-related G protein receptor X2
- MRGPRX2 (Mas-Related G-Protein Coupled Receptor Member X2) is a receptor expressed on mast cells found in barrier tissues (e.g., skin, airways, gastrointestinal tract) that is activated by many ligands, including various peptides and cytokines released from sensory neurons. In response to MRGPRX2 activation, mast cells degranulate and release histamine, tryptase, chylomicron, and related chemokines and cytokines, which in turn trigger urticaria, angioedema, type 2 inflammation (through the involvement of the adaptive immune system), chronic itch, and pain.
- barrier tissues e.g., skin, airways, gastrointestinal tract
- ligands including various peptides and cytokines released from sensory neurons.
- mast cells degranulate and release histamine, tryptase, chylomicron, and related chemokines and cytokines, which in turn trigger urticaria, angioedema,
- mast cells are one of the key effector cells in the immune response process and are an important link between the nervous system and the immune system. Because mast cells can be very close to nerve endings, they have a clear spatial advantage over other types of innate immune cells and can be the first to respond to sensory nerve activation. The dysregulation of mast cell-nerve cell interactions is currently considered to be a major factor in the pathogenesis of neurogenic inflammation and pain.
- mast cells When mast cells are activated, they release a wide range of proinflammatory cytokines and chemokines that can act on specific receptors on sensory nerve endings, including in particular neuropeptides such as Substance P (SP) and vasoactive intestinal peptide (VIP) that cause nerve endings to release neuropeptides.
- neuropeptides such as Substance P (SP) and vasoactive intestinal peptide (VIP) that cause nerve endings to release neuropeptides.
- SP Substance P
- VIP vasoactive intestinal peptide
- These neuropeptides can activate receptors on mast cells and induce mast cells to further degranulate and release a large number of downstream proinflammatory factors and chemokines, thereby causing neurogenic inflammation.
- neurogenic peptide substances such as SP and VIP can activate mast cells through MRGPRX2 receptors, indicating that MRGPRX2 contributes to the development of neurogenic inflammation and pain.
- MRGPRX2 In recent years, with the in-depth study of MRGPRX2, it has been found that the function of MRGPRX2 is becoming more and more important. This receptor is not only widely involved in the body's non-IgE-mediated hypersensitivity reactions, neurogenic inflammation, pain and itching, but also can promote the inherent immune response of the skin and intestines to harmful stimuli or pathogen invasion. Therefore, this receptor is likely to become a potential target for the development of anti-inflammatory and analgesic drugs in the future. MRGPRX2 antagonists have the potential to widely treat diseases mediated by mast cells by blocking the activation of MRGPRX2 and the degranulation of mast cells.

Abstract
提供MAS相关G蛋白受体X2(MRGPRX2)的拮抗剂及其用途,该MRGPRX2拮抗剂具有式(I)结构。
Description
本公开涉及医药领域,具体涉及MAS相关G蛋白受体X2(MRGPRX2)的拮抗剂、包含所述拮抗剂的组合物及其制备方法。
MRGPRX2(Mas-Related G-Protein Coupled Receptor Member X2)是一种在屏障组织(例如皮肤,气道,胃肠道)中发现的肥大细胞上表达的受体,该细胞被许多配体激活,包括从感觉神经元释放的各种肽类和细胞因子等。在响应MRGPRX2激活后,肥大细胞脱颗粒并释放组胺,类胰蛋白酶,乳糜,及相关的趋化因子和细胞因子,进而引发荨麻疹发痒,血管性水肿,2型炎症(通过适应性免疫系统的参与),慢性瘙痒和疼痛。
肥大细胞作为免疫反应过程中的关键效应细胞之一,是连接神经系统和免疫系统的重要环节,由于肥大细胞能够非常接近神经末梢,相对其他类型的先天性免疫细胞具有明显的空间优势,能够最先对感觉神经激活做出反应。而肥大细胞-神经细胞之间相互作用的失调目前被认为是神经源性炎症和疼痛发病机制的一个主要因素。
当肥大细胞被激活时,释放出广泛的促炎性细胞因子和趋化因子可作用于感觉神经末梢上的特定受体,其中特别包括引起神经末梢释放P物质(Substance P;SP)和血管活性肠肽(Vasoactive Intestinal Peptide;VIP)等神经肽,这些神经肽又可以激活肥大细胞上的受体,并诱导肥大细胞进一步脱颗粒释放大量下游的促炎因子和趋化因子,从而引起神经源性炎症。其中,神经源性的SP和VIP等肽类物质可通过MRGPRX2受体激活肥大细胞,这表明MRGPRX2有助于神经源性炎症和疼痛的发展。
近年来,随着对MRGPRX2研究的深入,发现MRGPRX2的功能越来越重要,该受体不仅广泛参与机体非IgE介导的超敏反应、神经源性炎症、疼痛和瘙痒等反应,而且能促进皮肤和肠道对有害刺激或病原体入侵的固有免疫反应,因此,该受体很可能成为将来抗炎和镇痛药物研发的潜在靶标。而MRGPRX2拮抗剂通过阻断MRGPRX2的活化和肥大细胞的脱颗粒,从而具有潜力广泛治疗由肥大细胞介导的疾病的潜力。

“过敏性休克”是对身体已对其高度敏感的抗原的一种极端的、经常危及生命的过
敏反应。经由MrgprB2的肥大细胞的激活因其IgE非依赖性肥大细胞激活和非组胺能瘙痒而受到关注。肥大细胞特异性MrgprB2是肥大细胞脱颗粒和相关非组胺能瘙痒的关键。
“哮喘”是指人的气道发炎、变窄和肿胀,并产生过多粘液,从而导致呼吸困难的一种病状。肥大细胞(MC)也会在平滑肌、T细胞和白细胞附近消退,其是作为哮喘的现象特性的气道高反应性和炎症的重要效应子细胞。即使在健康状态下仅存在少量转录物,MrgprX2转录物的水平在表征为从MCT到MCTC的表型转换的重度哮喘中也会增加。与MCT相比,重度哮喘中的肥大细胞MCTC群正在表达MrgprX2。鉴于激活MrgprX2的重度哮喘患者的肺部的SP水平增加,用小分子拮抗剂的治疗将有益于重度哮喘患者。当免疫系统对过敏原的反应导致哮喘症状时,这种类型的哮喘也被称为过敏性哮喘。
