constants for formation of N-1-hydroxymethyl derivatives were approximately twice those for formation of N-3-hydroxymethyl derivatives, and they were formed more rapidly throughout the pH 3--8 range. Substituents at C-5 of uracil had little effect on the thermodynamics of N-hydroxymethylation. The potential usefulness of N-hydroxymethyl compounds as prodrugs is discussed.
制备了1,3-二羟甲基尿嘧啶,3-羟甲基-1-甲基尿嘧啶和1-羟甲基-3-甲基尿嘧啶的固体样品,并通过光谱分析确认了它们的结构。还研究了在甲醛水溶液中形成N-羟甲基化尿嘧啶的热力学和动力学。用于形成N-1-羟甲基衍生物的平衡常数大约是用于形成N-3-羟甲基衍生物的平衡常数的两倍,并且它们在整个pH 3--8范围内的形成速度更快。尿嘧啶C-5处的取代基对N-羟甲基化的热力学影响很小。讨论了N-羟甲基化合物作为前药的潜在用途。
