(R)-(+)-Citronellal
Based on 1 Customer Validation
(R)-(+)-Citronellal ((+)-Citronellal) is a monoterpenoid compound and is one of the main components of essential oils from plants such as lemon grass. (R)-(+)-Citronellal has antibacterial, antifungal, and insecticidal activities. (R)-(+)-Citronellal alleviates the bitterness of caffeine by antagonizing the bitter taste receptors Tas2r43 (IC50 = 84 μM) and Tas2R46. (R)-(+)-Citronellal generates analgesic activity by activating the opioid receptor (broad-spectrum opioid receptor) pathway, and its effect is particularly significant for inflammatory pain.

제품 설명
In Vitro
(R)-(+)-Citronellal (0.5-1024 μg/mL, 48 h) acts on the cell wall and cell membrane of the fungus, and exhibits antibacterial activity against Candida albicans[1].
(R)-(+)-Citronellal (1-512 μg/mL, 24 h) has a bactericidal effect on Staphylococcus aureus and Staphylococcus epidermidis, but is ineffective against Salmonella typhimurium and Escherichia coli[2].
(R)-(+)-Citronellal (24 h) has insecticidal activity against Ae. albopictus larvae (LC₅₀ ranging from 384.81 to 395.09 ppm) and adult mosquito (LD₅₀ ranging from 133.059 to 218.962 μg/cm²)[2].

-
Animal Model:Rod rotation experiment, heating plate experiment, formalin test established in male Swiss mice over 4 weeks of age were used (26-32 g)[4]
-
Dosage:50, 100, 150 mg/kg
-
Administration:Intraperitoneal injection (i.p.), single dose
-
Result:Did not significantly shorten the time that mice spent on the rotating rod.
Was ineffective in the acute pain model caused by thermal stimulation.
Exhibited a significant analgesic effect on chemical-induced inflammatory pain, and was also effective against acute neuropathic pain at higher concentrations (150 mg/kg).
Could be completely blocked by the opioid receptor antagonist Naloxone (HY-17417A).

In Vivo:
Select the appropriate dissolution method based on your experimental animal and administration route.
- 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.
Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
Solubility: ≥ 2.5 mg/mL (16.21 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 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.
Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)
Solubility: ≥ 2.5 mg/mL (16.21 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.
Preparation of 20% SBE-β-CD in Saline (4°C, storage for one week): 2 g SBE-β-CD powder is dissolved in 10 mL Saline, completely dissolve until clear.
