| | L-Menthol Usage And Synthesis |
| Chemical Properties | white to light yellow crystal powde | | Uses | (1R,2S,5R)-(-)-Menthol (L-Menthol) is the natural form of Menthol. L-Menthol is used as: refreshing agent, food flavor,
cool and antipruritic drug, carminative drug. Menthol crystals is used for pers
onal care and cosmetics. | | Uses | L-Menthol is used as a cooling agent that strongly activates TRPM8.(Transient Receptor Potential Cation Channel, Subfamily M, Member 8 is a Protein Coding gene). It is used as analgesic (topical), antipruritic agent. It is used as: refreshing agent, food flavor, cool and antipruritic drug, carminative drug. Menthol crystals is used for pers onal care and cosmetics. | | Definition | ChEBI: A p-menthan-3-ol which has (1R,2S,5R)-stereochemistry. It is the most common naturally occurring enantiomer. | | Acquired resistance | (1R,2S,5R)-(-)-Menthol (L-Menthol) is the natural form of Menthol. L- and D-menthol are variants of the same molecule, but have a mirror-image structure in relation to each other, like the right and left hand. | | General Description | Produced and qualified by HWI pharma services GmbH.
Exact content by quantitative NMR can be found on the certificate. | | Flammability and Explosibility | Non flammable | | Biological Activity | l-Menthol inhibite the binding of 13 ligands (calcium channels, sodium channels, γ-aminobutyric acid type A (GABAA) receptor, GABA transporter, dopamine transporter, dopamine D4 receptor, adenosine A2a receptor, α2A-adrenergic receptor, histamine H2 receptor, bombesin receptor, angiotensin AT1 receptor, vasopressin V2 receptor, and leukotriene B4 receptor) with relatively high inhibition rates and acts on these ligands over a similar concentration range. It acts as a positive allosteric modulator of the GABAA receptor rather than an agonist. In periaqueductal grey neurons in rat midbrain slices, l-menthol was shown to prolong spontaneous GABAA receptor–mediated inhibitory current, most likely via a mechanism distinct from that of benzodiazepines. It acts on the dopamine D4 receptor and the dopamine transporter. l-menthol inhibits the [3H]-WIN35,428 binding, similar to GBR12909, suggesting that l-menthol inhibits the binding of dopamine to the dopamine transporter and leading to decreased dopamine uptake[1].
