Biological Activity

Description Asaraldehyde (Asaronaldehyde) is a natural COX-2 inhibitor, exhibiting 17-fold selectivity over COX-1.
COX-2 [2]
In vitro

Asaraldehyde is found to be the most abundant constituent, but is totally absent in its cultured broth and its natural host, C. kanehirae wood. On feeding with the acid-digested sawdust of C. kanehirae wood or vanillin to the broth for culture, Asaraldehyde is produced in both cultured broths. [1] Asaraldehyde shows 3.32% of prostaglandin H endoperoxide synthase-1 (COX-1) inhibitory activity and 52.69% prostaglandin H endoperoxide synthase-2 (COX-2) inhibitory activity, respectively at 100 mg/mL. Asaraldehyde shows selectivity towards COX-2 enzyme inhibition at 100 µg/mL. The COX-2/COX-1 ratio for Asaraldehyde is 17.68 at 100 µg/mL compared to solvent control. [2] Asaraldehyde down-regulates C/EBPβ, C/EBPδ, and C/EBPα. Asaraldehyde suppresses expression of PPARγ1 and PPARγ2. Asaraldehyde also significantly suppresses the expression of acetyl-CoA carboxylase (ACC). [2]

Protocol (from reference)

Cell Research:[3]
  • Cell lines: 3T3-L1 cells
  • Concentrations: 100 μg/mL
  • Incubation Time: 24 hours
  • Method: 3T3-L1 cells are seeded in 96-well plates at a concentration of 104 /well. Twenty-four hours after seeding, the cells are treated with 100 μg/mL of Asaraldehyde for 24 hours or for the whole 8-day differentiation period. Fully differentiated adipocytes are also treated with 100 μg/mL of Asaraldehyde for 24 hours-72 hours to test the cytotoxicity. At the end of treatment, cells are cultured with MTT at a final concentration of 0.5 mg/mL for another 4 hours. The purple MTT formazan is dissolved by DMSO and the absorbance at 570 nm is taken with a spectrophotometer. The absorbance is proportional to the viability of adipocytes.

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.
