General description
黄嘌呤是各种天然和合成医药活性化合物的重要组成部分。黄嘌呤的各种形式,如咖啡因、可可碱、茶碱,存在于巧克力、可可、茶、酵母、番茄、动物器官和咖啡中。黄嘌呤是一种嘌呤基天然杂环生物碱,由一个中心氮原子和一个与咪唑环稠合的嘧啶环组成。黄嘌呤由嘌呤代谢通路中的几种不同前体生成:鸟嘌呤脱氨酶催化的鸟嘌呤脱氨和黄嘌呤氧化还原酶催化的次黄嘌呤转化。
Biochem/physiol Actions
黄嘌呤参与核酸和核苷酸的代谢,是尿酸的前体。它是一种多功能化合物,在与呼吸道、中枢神经系统(CNS)、肾脏、胃、平滑肌细胞和心脏有关的多种药理学条件下有治疗作用。黄嘌呤可作为检测痛风的生物标志物。
