  Synthesis and Bioactivity of Potassium β-D-Glucopyranosyl 12-Hydroxy Jasmonate and Related Compounds

  摘要：

  Albizzia saman是一种豆科植物，它在白天气息张开的叶子，夜间则将叶子折叠休息。β-d-葡萄糖吡喃苷12-羟基茉莉酸酯（1）被鉴定为控制这种叶子运动的内源性化学因子。我们开发了一种简洁的合成方法，通过9个步骤从（+）-2合成光学上纯净的（−）-1，总产率为58%。同样，作为结构-活性关系（SAR）研究的类物质1的类似物，如epi-LCF（13）、对映体（14）和半乳糖苷（19）也被合成。SAR研究的结果强烈表明，1的闭叶活性的机制与甲基茉莉酸酯的机制不同，并且还表明涉及了一种不同类型的靶蛋白，该蛋白识别茉莉酸衍生物的反式异构体。

  Enantio-differential approach to identify the target cell for glucosyl jasmonate-type leaf-closing factor, by using fluorescence-labeled probe compounds

  摘要：

  Potassium beta-D-glucopyranosyl 12-hydroxyjasmonate (1) is a leaf-closing factor of Albizzia plants that induces nyctinastic leaf closure. In this paper, we synthesized probe 3 and its congener 4 by using a pair of enantiomerically pure methyljasmonate that was prepared by using optical resolution, and carried out fluorescence studies using 3 and 4 to identify the target cell of 1. The probe 3 bound to the motor cells of two Albizzia plants, whereas it could not bind to the motor cells of plants belonging to other genus. On the other hand, probe 4 did not bind to the motor cell at all. These results suggested that a specific receptor for I is involved in the motor cell of Albizzia plants. (c) 2006 Elsevier Ltd.

  The hormonal action of jasmonate in plants is controlled by the precise balance between its biosynthesis and inactivation. Oxidation of jasmonoyl-L-isoleucine at the C-12 position, which is catalyzed by cytochrome P450s CYP94B3 and CYP94C1, is thought to be one of the main inactivation pathways. In this study, an additional function of CYP94B3 was elucidated, as well additional jasmonoyl-L-isoleucine metabolites being investigated. It was found that CYP94B3 also catalyzes the hydroxylation of jasmonoyl-L-valine and jasmonoyl-L-phenylalanine, and that these hydroxyl compounds accumulated after wounding and possessed lower activity than non-hydroxylated compounds. Additionally, 12-O-beta-glucopyranosyl-jasmonoyl-t-isoleucine accumulated after wounding, suggesting that it is a metabolite of

  Albizzia saman, a leguminous plant, is known to open its leaves in the daytime and sleep at night with the leaves folded. β-d-Glucopyranosyl 12-hydroxyjasmonate (1) was isolated as an endogenous chemical factor controlling this leafmovement. We developed a concise synthesis of optically pure (−)-1 in 9 steps from (+)-2 with a total yield of 58%. Similarly, such analogs of 1 as epi-LCF (13), enantiomer (14), and galactoside (19) were synthesized for a structure activity relationship (SAR) study. The results of this SAR study strongly suggest that the mechanism for the leaf-closing activity of 1 would be different from that of methyl jasmonate, and also suggest the involvement of a different kind of target protein which recognizes the trans-isomer of a jasmonate derivative.
