nitriles to yield primary amines and also valuable α,α-dideutero analogues. Raneynickel proved to be a useful catalyst for the transformation of a wide range of nitriles under reasonably mild conditions with excellent deuterium incorporation (>90 %) and quantitative conversion. Among known model compounds, three new deuterated primary amines were prepared. The large-scale synthesis of deuterated tryptamine

intermediate from which thousands of monoterpene indole alkaloids are derived. The steady-state kinetics of SGD with a variety of strictosidine analogs revealed the substrate preferences of this enzyme at two key positions of the strictosidine substrate. Additionally, SGD from C. roseus turns over both strictosidine and its stereoisomer vincoside, indicating that although this enzyme prefers the naturally occurring
来自长春花的胡豆苷葡萄糖苷酶 (SGD) 催化胡豆苷的去糖基化,胡豆苷是一种中间体,从中衍生出数千种单萜吲哚生物碱。SGD 与各种胡豆苷类似物的稳态动力学揭示了这种酶在胡豆苷底物的两个关键位置的底物偏好。此外,来自 C. roseus 的 SGD 翻转了胡豆苷及其立体异构体长春花苷,这表明虽然这种酶更喜欢天然存在的非对映异构体,但该酶并不完全具有非对映选择性。强调了 SGD 底物特异性在 C. roseus 代谢工程工作中的影响。
