Based on 1 Customer Validation

DL-Menthol (Racementhol) is an orally active, GABA_aR positive allosteric modulator and UDP-glucuronosyltransferase (UGT) inhibitor that can cross the blood-brain barrier. DL-Menthol binds to GABA_AR and exhibits an allosteric activation effect, enhancing GABA-mediated chloride influx and inhibiting neuronal excitability. DL-Menthol can induce surgical anesthesia in fish and inhibit the metabolic detoxification of tobacco carcinogens by human liver and intestinal UGT enzymes, resulting in reduced NNAL-N-Gluc production.

製品説明

体内実験

DL-Menthol (0.2-3.0 mM; water administration; single; short-term treatment) induces surgical anesthesia in a dose-dependent manner in medaka (Oryzias latipes), goldfish (Carassius auratus) and zebrafish (Danio rerio) models. At high concentrations (3.0 mM), it first induces rapid movement and then turns to anesthesia. Pretreatment with a GABA_aR antagonist can prolong the anesthetic latency^[1].
0.5 mM DL-Menthol induces 100%, 90% and 100% surgical anesthesia in medaka, goldfish and zebrafish, respectively^[1].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Model:

Japanese medaka (Oryzias latipes), goldfish (Carassius auratus), zebrafish (Danio rerio) (medaka 1.6±0.2 cm, goldfish 3.2±0.4 cm, zebrafish 1.7± 0.2 cm), aquatic behavioral assay for surgical anesthesia^[2]
Dosage:

0.1-3.0 mM (dissolved in dechlorinated water, vehicle control: 50 μL DMSO in 300 mL water)
Administration:

Single-dose waterborne administration by adding to experimental tanks (300 mL water per fish), incubated for 6 minutes to observe anesthetic response; recovery time measured after transfer to fresh water
Result:

Low-concentration effect (0.2-0.5 mM):
- Surgical anesthesia induction: Loss of equilibrium and lack of response to touch stimulus. Response rates increased with dose: 8-17% at 0.2 mM, 80-100% at 0.4-0.5 mM across all three fish species. - Latency and recovery: Latency to anesthesia decreased with increasing dose (e.g., 225-330 seconds at 0.2 mM vs. 40-60 seconds at 0.5 mM). Recovery time averaged 228-640 seconds, showing no significant dose dependency.
High-concentration effect (3.0 mM):
- Rapid movement followed by anesthesia: 73% of medaka and 40-60% of goldfish exhibited rapid movement within 4.4 ± 1.2 seconds, followed by anesthesia with a latency of 44 ± 20 seconds. This response was specific to menthol and the cold nociceptor agonist allyl isothiocyanate, but not the cold receptor agonist icilin, suggesting involvement of TRPA1-like pathways.
GABA_aR antagonist interaction:
- Pretreatment with SR-95531 (70 μM for 30-120 min in medaka, 50-100 μM for 120 min in goldfish): Significantly prolonged anesthesia latency (e.g., from 26 ± 14 seconds to 66-99 seconds in medaka, 228 ± 10 seconds to 249-351 seconds in goldfish). Cold-water stimulation latency remained unchanged, confirming specificity to GABAₐR-mediated pathways.

Stock Solution Working Solution

For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.

Protocol 1

Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)

Solubility: ≥ 2.5 mg/mL (16.00 mM); Clear solution

This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).

Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.

Protocol 2

Add each solvent one by one: 10% DMSO 90% Corn Oil

Solubility: ≥ 2.5 mg/mL (16.00 mM); Clear solution

This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown). If the continuous dosing period exceeds half a month, please choose this protocol carefully.

Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 900 μL Corn oil, and mix evenly.

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
