Description
10 G Methyl Jasmonate Pure, also known as (±)-Jasmonic acid methyl ester, is a mixture of trans (3R/7R and 3S/7S) isomers that belongs to the group of plant stress hormones called jasmonates. These hormones naturally occur in plants when exposed to certain types of stresses, such as pathogen and herbivore attacks. Methyl jasmonate has various applications in different industries, including agriculture, pharmaceutical, and flavor.
Used in Agricultural Industry:
10 G Methyl Jasmonate Pure is used as a plant growth regulator for controlling blue mold decay in sweet cherry fruit caused by Penicillium expansum. It also serves as an elicitor to induce the synthesis of defensive proteinase inhibitor proteins in plant leaves, enrich the total anthocyanin content in radish sprouts, and stimulate the biosynthesis of trans-resveratrol in Vitis vinifera cv. Negramaro cell cultures.
Used in Pharmaceutical Industry:
10 G Methyl Jasmonate Pure is used as a potential anti-cancer agent that shows selective cytotoxic effects towards cancer cells. It suppresses proliferation and induces apoptosis in cancer cells by inhibiting mitochondrial hexokinase, which is overexpressed in cancer cells and contributes to their growth and survival. Additionally, (±)-Jasmonic acid methyl ester derivatives have potential as anti-inflammatory agents.
Used in Flavor Industry:
10 G Methyl Jasmonate Pure is used as a flavor ingredient in various applications, including plum, peach, apricot, and tutti-frutti flavors.
Used in Research and Development:
10 G Methyl Jasmonate Pure is used as a mediator of extensive plant transcriptome reprogramming/remolding on exogenous treatment to Salvia sclarea leaves and as a modulator in the expression of chalcone synthase (chs) and proline-rich cell wall protein (PRP), two wound-responsive genes in soybean suspension cultures. It also serves as a starting material in the synthesis of [13C,2H3]-MeJA, an internal standard used in the quantitative determination of MeJA in plant tissues, and as a test compound in the application of reduced graphene oxide–poly(safranine T) film on glassy carbon electrode (rGO–PST/GCE) in the electrochemical determination of MeJA in jasmine essential oil.
in vitro
it was found that (±)-jasmonic acid methyl ester, when applied to surfaces of tomato plants, could induce the synthesis of defensive proteinase inhibitor proteins. the presence of (±)-jasmonic acid methyl ester in the chamber atmosphere containing plants resulted in the accumulation of proteinase inhibitors in leaves of all studied three species [1]. another study found that (±)-jasmonic acid methyl ester could induce death in each of the studied cell lines, while other plant stress hormones could not affect normal human lymphocytes. in addition, (±)-jasmonic acid methyl ester caused apoptotic death, as measured by flow cytometric dna profile, characteristic nuclear morphology, and caspase-3 activity elevation [2].
in vivo
animal study showed that mice bearing el-4 lymphoma and treated with (±)-jasmonic acid methyl ester survived for significantly longer periods of time than untreated mice, suggesting that plant stress hormones might potentially be a new class of anti-cancer drugs [2].

Check Digit Verification of cas no
The CAS Registry Mumber 39924-52-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,9,9,2 and 4 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 39924-52:
(7*3)+(6*9)+(5*9)+(4*2)+(3*4)+(2*5)+(1*2)=152
152 % 10 = 2
So 39924-52-2 is a valid CAS Registry Number.

Synthesis of cis-Hedione and methyl jasmonate via cascade Baylis-Hillman reaction and Claisen ortho ester rearrangement
Chapuis, Christian,Buechi, George H.,Wueest, Hans
, p. 3069 - 3088 (2007/10/03)
The exocyclically unsaturated conjugated keto esters 10, obtained via a Claisen ortho ester rearrangement of the allylic hydroxy ketones 9, were either directly hydrogenated or partially isomerized into the endocyclically unsaturated tetrasubstituted didehydrojasmonoid intermediates 14, prior to a more selective hydrogenation with Pd/C in cyclohexane to the disubstituted oxocyclopentaneacetates 15 (Scheme 2). The key intermediates 9 were obtained either by a four-step sequence, including acetal protection/deprotection from enone 1, in the specific case of hydroxy ketone 9a (Scheme 1), or more directly and generally by a Baylis-Hillman reaction from cyclopent-2-en-1-one (16) and the appropriate aldehydes 17 (Scheme 2). The judicious choice of these aldehydes opens versatile modifications for the stereoselective introduction of the partially cis- or epimerized trans-C(2) jasmonoid side chain, while the Baylis-Hillman reaction, catalyzed by chiral [1,1′-binaphthalene]-2, 2′-diols (BINOLs) 19 (Scheme 3), may be efficiently conducted in a one-pot cascade fashion including the ortho ester Claisen rearrangement.
Behaviour of monocomplexed 1,4-diynes in the Khand reaction and use of ethylene equivalent techniques in a convenient route to tritium-labelled methyl jasmonate
Kerr, William J.,McLaughlin, Mark,Pauson, Peter L.
, p. 118 - 124 (2007/10/03)
1,2-Complexed hexacarbonyl(hepta-1,4-diyne)dicobalt, obtained from hexacarbonyl(propargyl acetate)dicobalt with tri-1-butynylaluminium, has been converted, by selective Khand annulation of the complexed triple bond with vinyl benzoate, to 2-pent-2-yn-1-ylcyclopent-2-en-1-one. By use of standard procedures this alkynyl cyclopentenone has been transformed into methyl jasmonate, allowing replacement of the final hydrogenation step by tritiation to produce the labelled analogue. Two alternative approaches to the intermediate pentynylcyclopentenone were examined and shown to be unsuccessful.
Stereochemical Control over Three Contiguous Stereogenic Centers in the Intramolecular Ene Reaction of Activated 1,6-Dienes. Application to the Synthesis of (±)-Methyl Cucurbate and (±)-Methyl Epijasmonate
Sarkar, Tarun K.,Ghorai, Binay K.,Nandy, Sandip K.,Mukherjee, Bireswar,Banerji, Asoke
, p. 6006 - 6011 (2007/10/03)
The influence of a protected alcohol group adjacent to the ene or enophile component on diastereoselectivity in both thermal and Lewis acid-catalyzed 5-(3,4) ene reactions of a series of 1,6-dienes 1-7 has been studied. The results indicate that its effect can be considerable, and in one example, with a gem-dimethyl group on the connecting chain and a large silyl protecting group on the hydroxyl, the diastereocontrol was almost perfect, with three stereogenic centers and one double bond geometry set up in one step, e.g., 4 → 10. This new finding was exploited in a synthesis of epijasmonoid natural products, (±)-methyl cucurbate (19) and (±)-methyl epijasmonate (18) starting from aldehyde 24, where the key step was a highly diastereocontrolled 5-(3,4) ene cyclization 23 → 22. 1 Indian Institute of Technology 2 BARC.
