(MRGPRX1) is a human sensory neuron-specific receptor and has been actively investigated as a therapeutic target for the treatment of pain. By use of two HTS screening hit compounds, 4-(4-(benzyloxy)-3-methoxybenzylamino)benzimidamide (5a) and 4-(2-(butylsulfonamido)-4-methylphenoxy)benzimidamide (11a), as molecular templates, a series of human MRGPRX1 agonists were synthesized and evaluated for their agonist
Mas 相关 G 蛋白偶联受体 X1 (MRGPRX1) 是一种人类感觉神经元特异性受体,作为治疗疼痛的治疗靶点已被积极研究。通过使用两种 HTS 筛选命中化合物,4-(4-(苄氧基)-3-甲氧基苄氨基)苯甲酰胺 ( 5a ) 和 4-(2-(丁基磺酰氨基)-4-甲基苯氧基) 苯甲酰胺 ( 11a ) 作为分子模板,a合成了一系列人 MRGPRX1 激动剂,并使用稳定转染人 MrgprX1 的 HEK293 细胞评估了它们的激动剂活性。在结构优化的后期阶段将苯甲脒部分转化为 1-氨基异喹啉部分,从而发现了一种高效的 MRGPRX1 激动剂N-(2-(1-aminoisoquinolin-6-yloxy)-4-methylphenyl)-2-methoxybenzenesulfonamide ( 16 ),不仅没有带正电荷的脒基,而且选择性优于阿片受体。在小鼠中,化合物16显示出对脊髓的有利分布,脊髓是
