ammonium carbamate
氨基甲酸铵
Carbamate(氨基甲酸酯)是一類含有氨基甲酸酯基團(結構式為NH₂COO⁻)的有機化合物,由氨基甲酸(NH₂COOH)衍生而來。這類化合物在化學工業和生物醫藥領域具有重要應用,其核心特性源于分子中的氨基與羰基相連形成的穩定結構。
從化學性質來看,氨基甲酸酯可通過氨基甲酸與醇類發生酯化反應合成,反應式為:
$$
NH₂COOH + ROH → NH₂COOR + H₂O
$$
此類化合物對水解和熱分解的穩定性使其廣泛應用于農藥領域,例如殺蟲劑呋蟲胺(Dinotefuran)即屬于第三代新煙堿類氨基甲酸酯。
在生物醫藥領域,氨基甲酸酯基團常作為藥物分子的功能基團。例如抗阿爾茨海默病藥物多奈哌齊(Donepezil)通過氨基甲酸酯結構抑制乙酰膽堿酯酶活性。此外,某些氨基甲酸酯類化合物還能作為前藥,通過代謝釋放活性成分。
權威文獻中,國際純粹與應用化學聯合會(IUPAC)将氨基甲酸酯歸類為"carbamic acid derivatives",其系統命名規則詳見IUPAC官網的《有機化學命名指南》。美國國家醫學圖書館的PubChem數據庫則收錄了超過8,000種氨基甲酸酯類化合物的理化數據及生物活性信息。
carbamate 是化學領域中的術語,具體解釋如下:
carbamate 是氨基甲酸(carbamic acid)的鹽或酯類化合物,化學通式為 $mathrm{NH_2COO^-}$。其名稱來源于氨基甲酸分子中的羧酸基團被替換為氨基。
氨基甲酸酯類農藥中毒(carbamates pesticide poisoning)需警惕,表現為神經系統症狀,需及時處理。
如需進一步了解具體化合物或應用案例,可參考化學詞典或專業文獻。
