[{"from": "human", "value": "Describe this molecule. [C][Branch1][Ring1][C][O][N]"}, {"from": "gpt", "value": "The molecule is a first generation monoethanolamine with antihistaminic property. Ethanolamine competes with free histamine for binding at the histamine (H)-1 receptor thereby acting as an inverse agonist that combines with and stabilizes the inactive form of the H1-receptor thereby shifting the equilibrium toward the inactive state. This leads to a reduction of the negative symptoms brought on by H1-receptor binding."}]
