    摘要:
    缺乏21-羟化酶的新生儿尿液中的类固醇代谢物主要是多羟基化的17-羟孕酮和雄激素代谢物,大多数结构不完全明确。这项研究是表征和鉴定这些特征的综合项目的一部分,以增强诊断并进一步阐明新生儿类固醇代谢的类型。在萃取和酶促共轭水解后,类固醇以甲基肟-三甲基甲硅烷基醚衍生物的形式在与四极杆和离子阱质谱仪联用的气相色谱仪上进行分析。在恒定激发条件下获得的GC-MS和GC-MS / MS光谱一起用于确定D-环和20-羟基和20-羟基孕烯(烯)的侧链的结构,这些烯基上没有氧基。 A环,B环和C环。考虑了D形环和侧链构型的所有可能组合。通过与氘代衍生物和硼氢化物还原的代谢物的光谱比较,可以将大多数片段解释为部分或完全的D环裂解,并丢失了侧链。还讨论了可能的重排离子。鉴定了140多种内源性代谢物。GC-MS / MS对于表征具有16,17-二羟基-20-氧代结构的化合物特别有用,该结构被解释为子宫内酶诱导的

    Structural requirements in 20-oxo-steroids for interaction with the catalytic site of 20.BETA.-hydroxysteroid dehydrogenase.
    摘要:
    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。

  • 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.

All possible combinations of D-ring and side chain configuration were considered. Most fragmentations could be interpreted as partial or complete D-ring cleavages with loss of the side chain, aided by comparison with spectra of deuterated
