  • Preparation of 3-carboxypropanoates of digitoxin and digoxin and their conjugates with L-tyrosine
    作者:Pavel Drašar、Vladimír Pouzar、Ivan Černý、Miroslav Havel、František Tureček、Daniela Schmiedová、Karel Vereš

    Digitoxin and digoxin 4'''-(3-carboxypropanoates)(4'''-hemisuccinates) III and X were prepared by an indirect method, using dicyclohexylcarbodiimide-induced condensation of the cardioglycoside with 4-(2,2,2-trichloroethoxy)-4-oxobutanoic acid in dichloromethane in the presence of 4-dimethylaminopyridine or pyridine followed by removal of the 2,2,2-trichloroethyl group with zinc in a mixture of tetrahydrofuran, acetic acid and water. The hemisuccinates III and X were condensed with L-tyrosine methyl ester in tetrahydrofuran, using N-ethoxycarbonyl-2-ethoxy-1,2-dihydroquinoline as the coupling reagent. Structure of the products was proved by 1H NMR and 13C NMR spectra. The conjugates IV and XI were labelled with [125I] in the L-tyrosine moiety. The obtained radioligands V and XII are designed as a part of the RIA system for cardioglycoside analyses.

    地高辛和地高辛4'''-(3-羧基丙酸酯)(4'''-半琥珀酸酯) IIIX 是通过间接方法制备的,使用二环己基碳二亚胺诱导的心糖苷与4-(2,2,2-三氯乙氧基)-4-氧代丁酸在二氯甲烷中在4-二甲基氨基吡啶或吡啶的存在下进行缩合,然后通过在四氢呋喃、乙酸和水的混合物中使用锌去除2,2,2-三氯乙基基团。半琥珀酸酯 IIIX 与L-酪氨酸甲酯在四氢呋喃中缩合,使用N-乙氧甲酰-2-乙氧基-1,2-二氢喹啉作为偶联试剂。产物的结构通过1H NMR和13C NMR光谱得到证实。缀合物 IVXI 在L-酪氨酸部分标记了[125I]。所获得的放射性配体 VXII 被设计为心糖苷分析的RIA系统的一部分。
  • New preparation of steroidal 3-hemisuccinates

    3-Hemisuccinates (3-(3-carboxypropanoates)) XI-XV, derived from cholesterol (I), (20R)-3β-hydroxy-21-norchola-5,22-dien-24 20-olide (II), estrone (III), (20E)-21-methoxycarbonyl-3β-hydroxypregna-5,20-diene (IV) and digitoxigenine (V), were prepared via the mixed succinates of the alcohols I-V and trichloroethanol (3-[4-(2,2,2-trichloroethoxy)-4-oxobutanoates] VI-X). The usual acylation of II and IV with succinic anhydride in pyridine failed.

    Three haptenes for the determination of Reichstein's compound S and progesterone were prepared in which hemisuccinyloxy group was attached to the β-side of the steroid skeleton (compounds VII, XIII and XV). These haptenes were bound to BSA and used for preparation of antisera. The specificity of these antisera was compared with that of antisera obtained with usual immunogens.

    为了测定Reichstein的化合物S和孕酮,制备了三种半抗原,其中半琥珀酰氧基团附着在类固醇骨架的β侧(化合物VII、XIII和XV)。这些半抗原被结合到BSA上,并用于制备抗血清。将这些抗血清的特异性与通常免疫原获得的抗血清进行了比较。

  • Photochemical 6β-hydroxylation of 11β-hydroxy-4-androstene-3,17-dione
    作者:Alexander Kasal、Jorga Smolíková
    DOI:10.1135/cccc19842932
    日期:——

    The utilisability of the photochemical oxygenation of Δ3,5-enol ethers of the type III is limited in 11β-hydroxy derivatives which under the conditions of enol-etherification undergo dehydration to a considerable extent. A method for the protection of the 11β-hydroxy group in the form of a 11-keto group has been elaborated; after the enol-etherification the keto group can be reduced back to the 11β-hydroxy group.

    照片化学氧化Δ3,5-烯醇醚类型III的可利用性在11β-羟基衍生物中受到限制,在烯醇醚化条件下会发生脱水反应。已经制定了一种保护11β-羟基团的方法,以11-酮基团的形式进行保护;在烯醇醚化后,酮基团可以还原为11β-羟基团。
