hydrolysis kinetics of a series of N-Mannich bases of carboxamides, thioamides, and other NH-acidic compounds were studied to assess their suitability as prodrugs for various drugs. The pH-rate profiles for the compounds were determined at 37 degrees and were accounted for by assuming the spontaneous decomposition of both free and protonated Mannich bases. The reaction rate for the free base increased
研究了羧酰胺,硫代酰胺和其他NH酸性化合物的一系列N-曼尼希碱的水解动力学,以评估它们作为各种药物的前药的适用性。化合物的pH速率分布在37度下测定,并假设游离的和质子化的曼尼希碱均自发分解。随着N-曼尼希碱的胺组分的空间效应增加以及酰胺组分的酸度增加,游离碱的反应速率急剧增加。N-曼尼希碱可能是用于NH-酸性化合物(如各种酰胺和尿素)和胺的有用前药。
