  Metabolism of 5′α,8′-cycloabscisic acid, a highly potent and long-lasting abscisic acid analogue, in radish seedlings

  摘要：

  We synthesized 5'alpha,8'-cycloabscisic acid (CycloABA), a highly potent and long-lasting abscisic acid (ABA) analogue, by a different method from that reported before. CycloABA fed to radish seedlings had more metabolic tolerance than ABA. The major metabolite of CycloABA was the glucose conjugate, which was the minor metabolite of ABA. The 8'-hydroxylated metabolite and its cyclized isomer, which were major metabolites of ABA, were not found as metabolites of CycloABA. The present results suggest that the highly potent and long-lasting activity of CycloABA is caused by resistance to ABA 8'-hydroxylase, and that CycloABA is partially metabolized to the glucose conjugate by ABA glucosyltransferase.

  requirement for the biological activity of abscisic acid, the cyclopropane analogues 6, 7, 9, and 10 were synthesized and their biological activities in four bioassays were tested. The activity of the achiral cyclohexadienone analogue 8 also was examined. Analogue 7 in which the 6′ β-substituent is constrained essentially to the axial-like orientation between axial and bisectional showed no activity, while 6

  为了研究对脱落酸的生物活性构象环需求，环丙烷类似物6，7，9，和10被合成和它们在生物测定4的生物活性进行了测试。还检查了非手性环己二酮类似物8的活性。类似物7，其中6'β-取代基基本上被约束在轴向和二等分之间的轴向样取向上，没有活性，而6和8在C-6'β处无轴状取代基，而与构象偏好无关，其表现出与脱落酸同等的活性。该结果表明，在环的β侧的轴向取代基对活性是致命的。脱落酸的活性构象是C-9'是赤道的且侧链在假轴和双节之间的构象，即与假链的侧链接近的偏爱的半椅子而不是较少的构象。偏爱半椅子和侧链伪赤道仪。
