  Novel heterogeneous cobalt-based catalysts have been prepared by pyrolysis of cobalt complexes with nitrogen ligands on different inorganic supports. The activity and selectivity of the resulting materials in the hydrogenation of nitriles and carbonyl compounds is strongly influenced by the modification of the support and the nitrogen-containing ligand.

  长期以来，双或双共轭类固醇代谢物是类固醇谱中的次要成分，传统上已通过费力和间接分馏，水解和气相色谱-质谱（GC-MS）分析进行研究。最近，类固醇双（硫酸盐）（又称二硫酸盐或双硫酸盐）参考物质的合成和表征，使得液相色谱-串联质谱（LC-MS / MS）能够研究这种代谢物类别并产生恒定的离子流失（CIL）扫描方法可直接和非靶向地检测类固醇双（硫酸盐）代谢产物。直接LC-MS / MS检测其他双共轭类固醇的方法，如类固醇bisglucuronide和混合类固醇硫酸葡萄糖醛酸苷代谢产物，具有显示更完整的类固醇概况的巨大潜力。然而，获得LC-MS / MS方法开发，代谢物鉴定或定量所必需的类固醇双葡糖苷酸或硫酸葡糖苷酸参考物质受到严重限制。在这项工作中，通过化学硫酸化和/或酶促葡萄糖醛酸化反应的有序组合，合成了十种甾体类双葡糖醛酸苷和十种甾体硫酸盐类葡糖醛酸苷参考物质。使用NMR和MS方法纯化和表征
• Structural requirements in 20-oxo-steroids for interaction with the catalytic site of 20.BETA.-hydroxysteroid dehydrogenase.

  Kinetic measurements were made to investigate the interaction of 20β-hydroxysteroid dehydrogenase and a series of steroids with C-17 and/or C-21 hydroxyl groups, and the role of the region around C-17 and C-21 on the interaction of the reacting 20-oxo group with the catalytic site of the enzyme was considered. Substitution of a hydroxyl group for hydrogen at C-21 of 17-deoxy-steroid derivatives caused a significant decrease in the apparent Vmax value (to about one-sixth to one-ninth), but a slight increase in the apparent Km value (about 1.1- to 1.8-fold). The same change at C-21 of 17-hydroxy-steroid derivatives caused little or no decrease in the apparent Vmax value, but an increase in the apparent Km (about 1.4- to 1.8-fold) occurred which was similar to that with 17-deoxy-steroid derivatives. In 21-deoxy-11-deoxy-steroid derivatives, a 17α-hydroxyl substituent had little effect on the apparent Km value (about 0.8- to 1.1-fold) and produced a slight decrease in the apparent Vmax value (to about three-quarters to two-fifths). Introduction of a 17α-hydroxyl group into 21-deoxy-11-oxo-steroid derivatives led to a significant decrease in the apparent Km value (to about one-seventh) and a moderate decrease in the apparent Vmax value (to about five-sixths to one-half). Introduction of a 17α-hydroxyl group into 21-hydroxy-steroid derivatives caused the apparent Vmax value to increase by about 1.8- to 11-fold, but caused little or no decrease in the apparent Km value. These results suggest that the hydroxyl group at the 21- or 17α-position directly restricted the conformation and the orientation of the 20-oxo group towards the catalytic site of the enzyme and influenced the hydrogen transfer stage in the catalytic process, and also that, of the substituents at the 21- and 17α-positions, the latter may preferentially affect the reaction efficiency of the 20-oxo group. The presence of an oxo group at C-11 had an indirect influence on the effects of the substituents at the 21- and 17α-positions. The optimum orientation of the 20-oxo group for the catalytic reaction may occur in 21-deoxy-17-deoxy-11-deoxy-steroid derivatives. In an ideal ternary complex, the 20-oxo group of the steroid may project towards the β-face of the steroid ring and the conformation between the 20-oxo group and α-hydrogen of C-17 is nearly staggered, while that between C-21 and the α-hydrogen of C-17, looking along the C-17 to C-20 axis, is in a skew form ; the 20-oxo group is orientated rather far from the methyl group at the β-position of C-13 and more towards the β-chain of C-16.

  进行了动力学测量，以研究20β-羟类固醇脱氢酶与一系列具有C-17和/或C-21羟基的类固醇之间的相互作用，并考虑了C-17和C-21附近区域对反应的20-氧基与酶催化位点相互作用的影响。将C-21的氢替换为羟基的17-脱氧类固醇衍生物导致表观Vmax值显著下降（降至约六分之一到九分之一），但表观Km值略微增加（约1.1到1.8倍）。在17-羟基类固醇衍生物的C-21处进行相同的改变对表观Vmax值几乎没有或没有造成下降，但表观Km值却增加（约1.4到1.8倍），这与17-脱氧类固醇衍生物的变化相似。在21-脱氧-11-脱氧类固醇衍生物中，17α-羟基取代体对表观Km值影响不大（约0.8到1.1倍），并导致表观Vmax值轻微下降（降至约三分之四到五分之二）。在21-脱氧-11-氧基类固醇衍生物中引入17α-羟基使表观Km值显著降低（降至约七分之一），而表观Vmax值中度下降（降至约五分之六到一半）。在21-羟基类固醇衍生物中引入17α-羟基使表观Vmax值增加约1.8到11倍，但对表观Km值几乎没有影响。这些结果表明，位于21或17α位点的羟基直接限制了20-氧基与酶催化位点之间的构象和取向，并影响了催化过程中的氢转移阶段。此外，在21和17α位点的取代基中，后者可能更优先影响20-氧基的反应效率。C-11的氧基的存在对21和17α位点取代基的影响具有间接作用。20-氧基在催化反应中的最佳取向可能发生在21-脱氧-17-脱氧-11-脱氧类固醇衍生物中。在一个理想的三元复合物中，类固醇的20-氧基可能朝向类固醇环的β面突出，且20-氧基与C-17的α-氢之间的构象几乎呈交错状态；而C-21与C-17的α-氢之间的角度在C-17至C-20轴上是倾斜的；20-氧基在空间上较远离C-13的β位甲基，更靠近C-16的β链。
