Biological activity of methyl 7-methyl-jasmonates
Phytochemistry, 1995Abstract Stereochemically-locked cis- and trans-7-methyl derivatives of methyl jasmonate were found to have low biological activity in several assays, including that with Bryonia dioica. This suggests that the introduction of the locking methyl group at position 7 considerably lowers affinity for the jasmonate receptor, presumably owing to a steric ...

An Efficient Synthesis of Methyl (±)‐Jasmonate and (Z)‐Jasmone
Helvetica Chimica Acta, 1978AbstractAn efficient synthesis of methyl (±)‐jasmonate and (Z)‐jasmone is described. The Key step is a phase‐transfer reaction between cyclopentane (9) and 1, 4‐dibromo‐2‐pentene (6a/b) to give the spiro [2.4]hepten‐4‐ones 4a and 4b.

The absolute configuration of methyl jasmonate
Tetrahedron, 1965Abstract The absolute configuration of the jasmine oil constituent methyl jasmonate has been determined. Methyl dihydrojasmonate was synthesized from (−) 3-oxocyclopentaneacetic acid, whose configuration was established by three independent methods: (a) ORD comparison with 3-methylcyclopentanone, (b) synthesis from optically active norcamphor, and (c)

Methyl jasmonate alleviates arsenic toxicity in rice
Plant Cell Reports, 2020Methyl jasmonate improved yield of both rice varieties under arsenic toxicity by alleviating oxidative stress through increasing the activity of antioxidant enzymes and decreasing arsenic accumulation by modulating arsenic transporters. Human health and rice cultivation are threatened by arsenic (As) contamination. Methyl jasmonate (MJ), as a regulator

Physiologia Plantarum, 2004
The oxylipin pathway mediates wound‐ and herbivore‐induced defense reactions in Nicotiana attenuata as evidenced by a transient jasmonic acid (JA)‐burst that precedes these defense responses. The fate of this induced JA‐burst remains unknown. Two derivatives of JA, its methylester, methyl jasmonate (MeJA) and cis‐jasmone (cisJ), are thought to be a ...

Antinociceptive effects of methyl jasmonate in experimental animals
Journal of Natural Medicines, 2011Methyl jasmonate (MJ) is a chemical compound that has been postulated to play a role in plant wound and pathogen responses. While the anti-inflammatory property of MJ has been reported in literature, no studies have been carried out to describe its role in the modulation of pain.

Optical Isomers of Methyl Jasmonate in Tea Aroma
Bioscience, Biotechnology, and Biochemistry, 1996Two epimers of methyl jasmonate were optically resolved by capillary gas chromatography, using heptakis (2,3,6-tri-O-methyl)-β-cyclodextrin as the chiral stationary phase. In the tea volatile concentrates, both of these epimers were present as only one enantiomer, their absolute configurations being ascertained as (-)-(1R,2R)-methyl jasmonate and ...

Regulation of water transport in Arabidopsis by methyl jasmonate
Plant Physiology and Biochemistry, 2019Following a stress event, jasmonate-dependent signaling pathway triggers a shift from growth to defense responses that are accompanied by the cessation of growth in many plants. However, the processes leading to this growth inhibition remain obscure. In this study, we provide evidence for a rapid inhibition of cell hydraulic conductivity (Lp) by methyl
