An enzymatic preparation from human brain converts tryptamine to tryptoline (9H-1,2,3,4-tetrahydropyrido[3,4-b]indole) in the presence of 5-methyltetrahydrofolic acid. Similarly, N-methyltryptamine and 5-hydroxytryptamine yield 1-methyltryptoline and 5-hydroxytryptoline, respectively. Neither in vitro nor in vivo formation of these compounds by human tissues has been described.
人脑的一种酶制剂在5-甲基四氢叶酸存在的情况下可将色胺转化为色醇(9H-1,2,3,4-四氢吡啶并[3,4-b]吲哚)。同样,N-甲基色胺和5-羟色胺分别生成1-甲基色醇和5-羟色醇。人体组织在体外或体内形成这些化合物的情况均未见报道。
