对映纯d-苯基甘氨酸及其衍生物是重要的一组手性氨基酸,在制药工业中具有广泛的应用。但是,现有的d-苯基甘氨酸合成方法主要依靠有毒的氰化物化学和多步法。为了提供绿色和安全的替代品,我们设想了级联生物催化,分别由外消旋扁桃酸,苯乙烯和生物基1-苯基丙氨酸一锅法合成d-苯基甘氨酸。重组大肠杆菌(LZ110)被设计为在一个锅中共表达四种酶以催化三步反应,将扁桃酸(210 mM)转化为29.5 g L -1的对映体纯的d-苯基甘氨酸(195 mM),转换率达93%。使用相同的全细胞催化剂,还可以由相应的扁桃酸衍生物以高转化率(58-94%)和非常高ee(93-99%)的方式生产其他十二种d-苯基甘氨酸衍生物。构建了表达7种酶的大肠埃希氏菌(LZ116),可通过一锅6步级联生物转化法将苯乙烯转化为对映体纯的d-苯基甘氨酸,转化率为80%。通过相同的级联反应,十二种取代的d-苯基甘氨酸也从相应的苯乙烯衍
The present invention relates generally to amide group containing pharmaceutical agents, and in particular, to amide containing heterobicyclic metalloprotease inhibitor compounds. More particularly, the present invention provides a new class of heterobicyclic MMP-13 inhibiting compounds, that exhibit an increased potency in relation to currently known MMP-13 inhibitors.
