  The preparation of three fluorescence-labelled derivatives of testosterone

  摘要：

  Three fluorescence-labelled derivatives of testosterone were prepared consisting of the steroid separated from the fluorochrome by a hydrocarbon "bridge". "Bridges" of different lengths (C2 to C7) were used as the length required to avoid steric hindrance effects by the fluorochrome in studies on steroid-protein binding was unknown. The three derivatives prepared were: 17 beta-hydroxy--4-androsten-3-one 3-(O-(N-(2'-mercapto)ethyl)carbamoylmethyl)oxime, 17 beta-hydroxy-4-androsten-3-one 3-(O-(N-(3'-amino)propyl)carbamoylmethyl)oxime and 17 beta-hydroxy-4-androsten-3-one 3-(O(N-(7'-amino)heptyl)carbamoylmethyl)oxime. These were then coupled with either a dansyl or a fluorescein molecule. Overall yields were sufficient and the products immunoreactive with anti-testosterone antiserum.

  大肠杆菌葡糖醛酸合成酶的实验和动力学研究：合成葡糖醛酸苷缀合物的工程化酶。

  摘要：

  在许多领域，包括药物开发，运动药物测试和农业残留物的检测，葡萄糖醛酸苷代谢产物的检测和研究都是必不可少的。因此，开发用于合成葡糖醛酸苷缀合物的改进方法是重要的目标。衍生自大肠杆菌β-葡萄糖醛酸苷酶的糖合酶在温和条件下提供了高效，可扩展的一步合成β-葡萄糖醛酸苷的方法。在本文中，我们报告了大肠杆菌的实验和动力学研究葡糖醛酸合成酶，包括受体底物，pH，温度，助溶剂和去污剂的影响，从而为葡糖醛酸苷合成提供了最佳条件。酶动力学还揭示了在葡萄糖醛酸合酶反应中可能同时发生底物和产物抑制，但是可以通过明智地选择受体和供体底物浓度来改善这些作用。进行了临时极性取代基的研究，以改善疏水性甾体受体的水溶性。以这种方式，通过三个步骤实现了甾族代谢物脱氢表雄酮3-β- d-葡萄糖醛酸苷的合成，并且脱氢表雄酮的总产率为86％。

  Each testosterone-[125I]iodinated histamine derivative where[125I)iodinated histamines were linked to respective 15α- and 15β-carboxymethyltestosterone (15α-and 15β-CMT), testosterone-3-(O-carboxymethyl)oxime (T-3-CMO) and testosterone-17β-hemisuccinate (T-17-HS) were tested for their usefulness as radiotracers in testosterone immunoassay. In the use of anti-15α- and 15β-CMT antisera produced in rabbits against 15α- and 15β-CMT-bovine serum albumin (BSA) conjugates, the antisera with 15α- and 15β-CMT-[125I]iodinated tracers showed low sensitivity and somewhat low specificity in comparison with those of the antisera with tritiated testosterone (T-3H). On the other hand, the antisear with T-3-CMO-[125I]iodinated tracer showed high sensitivity but low specificity for 5α-dihydrotestosterone(5α-DHT)in comparison with T-3H. The T-17-HS-[125I]iodinated tracer was not bound to the antisera. In the use of anti-15α- and 15β-CMT antisera produced in rabbits by pretreatment with 15α-carboxymethyl-5α-DHT linked to a copolymer of D-glutamic acid and D-lysine followed by immunization with 15α- and 15β-CMT-BSA, the antisera with homologous[125I]iodinated tracer showed high sensitivity and specificity.

• Design and synthesis of a Mn(III)-porphyrin steroid conjugate used as a new cleavable affinity label: on the road to semi-synthetic catalytic antibodies

  We here report the synthesis of a novel porphyrin-steroid conjugate which was designed for the site-specific incorporation of a non-natural heme cofactor at the binding site of an anti-estradiol antibody, in order to get a semi-synthetic catalytic antibody with a monooxygenase-like activity. The general strategy involved a coupling reaction between a testosterone modified by an arm bearing a cleavable disulfide bridge and a meso-tetraarylporphyrin bearing two successive meso-ortho-substituted-phenyl rings, alpha,alpha-5,10-bis-[o-(2-carboxyethyl)carboxamido}phenyl]-15,20-diphenyl-porphyrin. The final porphyrin-steroid conjugate was successfully purified and fully characterized, and was subsequently metalated with manganese acetate. The metalloporphyrin moiety will be used to be coupled with the antibody to generate a new biocatalyst with monooxygenase-like activities. (C) 2004 Elsevier Ltd. All rights reserved.
