(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
