Coronalon是一种合成的6-乙基indanoyl异亮氨酸缀合物，被设计为一种高活性的八烷十烷类植物激素，参与抗虫和抗病。在9种不同的植物系统中，研究了受冠隆影响的生物活性谱，这些系统对茉莉酸盐和/或12-氧-植物二烯酸有特异性反应。在所有的生物分析分析中，coronalon在低微摩尔浓度下表现出普遍的强活性。获得的结果表明，诱导(i)细胞培养和植物组织中与防御相关的次生代谢物积累，（ii）特定的非生物和生物胁迫相关基因表达，以及（iii）根生长迟缓。该化合物具有诱导植物胁迫反应的普遍活性，且其合成简单、高效，可作为植物胁迫生理学各方面研究的重要工具。此外，coronalon还可用于农业，以诱导植物抵抗各种侵略者。(C) 2004年欧洲生化学会联合会。Elsevier B.V.版权所有。
Coronalon, a synthetic 6-ethyl indanoyl isoleucine conjugate, has been designed as a highly active mimic of octa-decanoid phytohormones that are involved in insect and disease resistance. The spectrum of biological activities that is affected by coronalon was investigated in nine different plant systems specifically responding to jasmonates and/or 12-oxo-phytodienoic acid. In all bioassays analyzed, coronalon demonstrated a general strong activity at low micromolar concentrations. The results obtained showed the induction of (i) defense-related secondary metabolite accumulation in both cell cultures and plant tissues, (ii) specific abiotic and biotic stress-related gene expression, and (iii) root growth retardation. The general activity of coronalon in the induction of plant stress responses together with its simple and efficient synthesis suggests that this compound might serve as a valuable tool in the examination of various aspects in plant stress physiology. Moreover, coronalon might become employed in agriculture to elicit plant resistance against various aggressors. (C) 2004 Federation of European Biochemical Societies. Published by Elsevier B.V.
