    抗体在类固醇环 A 形成中模拟天然氧化角鲨烯-环化酶作用
    摘要:
    阳离子环化是抗体催化的最苛刻的反应之一。这些研究提供了宝贵的机理见解,同时开辟了形成甾体碳框架的可能性。然而,它们涉及的底物含有与伯碳中心相邻的芳基磺酸酯基团,这在天然阳离子环化过程中未观察到。本文介绍了我们早期工作的扩展,现在重点关注类似于三萜生物合成中所见的底物。三种抗体 15D6、20C7 和 25A10 已通过使用 4-氮杂类固醇氨基氧化物半抗原(称为 HA8)进行免疫而产生,该半抗原可启动氧化角鲨烯衍生物的阳离子环化并在中性点催化羊毛甾醇核的 A 环的形成酸碱度。抗体 HA8-25A10 动力学解析其外消旋底物。底物的设计基于用于特异性结合的双锚模型,该模型包括在头部展示一个官能团(环氧化物...

  • Internal Oxidosqualenes: Determination of Absolute Configuration and Activity as Inhibitors of Purified Pig Liver Squalene Epoxidase
    作者:Jose-Luis Abad、Josefina Casas、Francisco Sanchez-Baeza、Angel Messeguer
    DOI:10.1021/jo00117a014
    日期:1995.6
    The preparation and characterization of oxidosqualenes 3-(6R,7R), 3-(6S,7S), 4-(10R,11R), and 4-(10S,11S) is reported. Squalenediol 6 was converted into the corresponding mixture of(R)-Mosher esters 8 and 9, which were separated by semipreparative HPLC. Esters 8 and 9 were reduced to the chiral diols 6-(6R,7S) and 6-(6S,7R), respectively, which were finally converted into the corresponding epoxides 3-(6R,7R) and 3-(6S,7S). A similar procedure was used for the preparation of chiral epoxy derivatives 4-(10R,11R) and 4-(10S,11S) from esters 10 and 11, respectively. The determination of the absolute configuration of these epoxides was carried out by using the method reported by Ohtani et al. (J. Am. Chem. Sec. 1991, 113, 4092), which was adapted to the case of racemic mixtures from synthetic origin. For this purpose, the (R)-Mosher esters derived from the enantiomers of squalenediols 6 or 7 were used. The validity of this approach was confirmed by the absolute configuration found for the three squalenediols 6-(6R,7R), 6-(6S,7S), 7-(10R,11R), and 7-(10S,11S) formed in the Sharpless asymmetric dihydroxylation of squalene (Crispino, G. A.; Sharpless, K. B. Tetrahedron Lett. 1992, 33, 4273). Results on the inhibitory activity of oxidosqualenes 3-(6R,7R), 3-(6S,7S), 4-(10R,11R), and 4-(10S,11S) using purified squalene epoxidase (SE) fi om pig liver showed that epoxide 3-(6S,7S) was the best inhibitor within the compounds assayed (IC50 = 6.7 mu M), although oxidosqualene 4-(10R,11R) also exhibited a moderate inhibitory activity (IC50 = 25 mu M). The inhibition elicited by the epoxy derivative 3-(6S,7S) was competitive with respect to squalene (K-i = 2.7 mu M). This activity is comparable to that reported for the most potent competitive SE inhibitors described so far. Finally, incubation of oxidosqualene 3-(6S,7S) with purified SE led to the formation of dioxidosqualene 22-(3S,6S,7S), whereas its regioisomer 23-(3S,18S,19S) was not detected. In contrast, incubation of epoxide 3-(6R,7R) under the same conditions afforded a mixture of dioxides 22-(3S,6R,7R) and 23-(3S,18R,19R) in a 5:12 molar ratio. The fact that oxidosqualenes 3 and 4 have been found in nature, and our previous results showing that racemic dioxide 23 is a potent inhibitor of oxidosqualene-lanosterol cyclase in rat liver microsomes (Abad, J. L.; et al. J. Org. Chem. 1993, 58, 3991), confers a potential physiological relevance to the results reported herein.
