trans-Methylisoeugenol
(E)-Methyl isoeugenol (trans-Methylisoeugenol) is a natural food flavour, it also has anxiolytic and antidepressant like properties. Eugenol methyl ether(trans-Methylisoeugenol) can cause moderate reversible inhibition of glutathione S-transferases (GSTs)(I25 ranged from 0.2 to 5.4 mM for human GSTs and from 0.4 to 4.9 mM for rat GSTs).The use of isoeugenol methyl ether(trans-Methylisoeugenol) is described as an agent to inhibit and/or prevent the growth of and/or to destroy micro-organisms causing bad breath and/or to combat bad breath.

Providing storage is as stated on the product vial and the vial is kept tightly sealed, the product can be stored for up to
24 months(2-8C).
Wherever possible, you should prepare and use solutions on the same day. However, if you need to make up stock solutions in advance, we recommend that you store the solution as aliquots in tightly sealed vials at -20C. Generally, these will be useable for up to two weeks. Before use, and prior to opening the vial we recommend that you allow your product to equilibrate to room temperature for at least 1 hour.
Need more advice on solubility, usage and handling? Please email to: service@chemfaces.com
The packaging of the product may have turned upside down during transportation, resulting in the natural compounds adhering to the neck or cap of the vial. take the vial out of its packaging and gently shake to let the compounds fall to the bottom of the vial. for liquid products, centrifuge at 200-500 RPM to gather the liquid at the bottom of the vial. try to avoid loss or contamination during handling.

Anxiolytic and antidepressant like effects of natural food flavour (E)-methyl isoeugenol.[Pubmed:
24920211 ]
(E)-methyl isoeugenol (MIE, trans-Methylisoeugenol) is a natural food flavour that constitutes 93.7% of an essential oil from Pimenta pseudocaryophyllus leaf. The leaf extracts of this species are used as a calming agent. As a ubiquitous food additive, the application of MIE for treating mood disorders appears to be globally attractive.
METHODS AND RESULTS:
Hence, we sought to evaluate general pharmacological activities, anticonvulsant, anxiolytic and antidepressant effects and the possible mechanisms of MIE actions. MIE at 250 and 500 mg kg(-1) potentiated the hypnotic effect of sodium pentobarbital. However, MIE did not protect against PTZ-induced convulsion. Except for MIE at 500 mg kg(-1), parameters evaluated in the LDB, EPM and OF demonstrated an anxiolytic like property of MIE. This effect was blocked by WAY100635 pretreatment. MIE at 500 mg kg(-1) elicited a reduction in locomotor activity of the mice in the OF. Anti-immobility effect of MIE 250 mg kg(-1) in the FST suggested an antidepressive like property. Unlike AMPT, pretreatment with PCPA reversed the antidepressant like effect of MIE.
CONCLUSIONS:
Our findings demonstrated anxiolytic and antidepressant like properties of (E)-methyl isoeugenol and suggested the participation of serotonergic pathways.

Inhibition of rat, mouse, and human glutathione S-transferase by eugenol and its oxidation products.[Pubmed:
8620581]
METHODS AND RESULTS:
The irreversible and reversible inhibition of glutathione S-transferases (GSTs) by eugenol was studied in rat, mouse and man.
The reversible inhibition of human and rat GST by eugenol, eugenol methyl ether, isoeugenol methyl ether(trans-Methylisoeugenol), 2-allylphenol and 4-propylphenol was also studied using purified isoenzymes. The reversible inhibition of human and rat GSTs, using 1-chloro-2,4-dinitrobenzene as substrate, was expressed as I25. All compounds caused moderate reversible inhibition (I25 ranged from 0.2 to 5.4 mM for human GSTs and from 0.4 to 4.9 mM for rat GSTs).
CONCLUSIONS:
In rat, eugenol methyl ether was the strongest inhibitor. In human, the overall inhibiting capacities of eugenol, eugenol methyl ether, isoeugenol methyl ether (trans-Methylisoeugenol) and 4-propyl phenol were more or less similar; 2-allylphenol was the poorest inhibitor.
