摘要 四氢生物蝶呤(tetrahydrobiopterin,BH4)最早是作为芳香族氨基酸羟化酶的必需辅助因子被认知。此后,人们对一氧化氮——"内皮源性血管舒张因子"的研究不断深入,发现BH4也是血管内皮细胞通过一氧化氮合酶(nitric oxide synthase,NOS)产生一氧化氮的必需辅助因子,当BH4缺乏时,一氧化氮合成减少并且氧自由基产生增加,最终导致血管内皮功能异常。高血压是一种常见的临床疾病,其发生发展与一氧化氮的生物利用度密切相关,因而与BH4之间也有着紧密的联系。1 BH4概述BH4是生物蝶呤的活性辅酶形式,具有还原性,是8个重要的加单氧酶的必需辅助因子,包括4个芳香族氨基酸羟化酶(aromatic amino acid hydroxylase,
