Asaronaldehyde is a COX-2 inhibitor, exhibiting 17-fold selectivity over COX-1, it's a natural product isolated and purified from the rhizoma of Acorus tatarinowii Schott.
Asarylaldehyde (2,4,5-TMBA) is a natural COX-2 inhibitor, which isolated from carrot (Daucus carota L.) seeds significantly inhibits cyclooxygenase II (COX-2) activity at the concentration of 100 μg/mL compared to three commercial nonsteroidal anti-inflammatory drugs Aspinin, Ibuprofen, and Naproxen at their IC50 values 180, 2.52, and 2.06 μg/mL, respectively. 2,4,5-TMBA, a natural inhibitor of cyclooxygenase-2, suppresses adipogenesis and promotes lipolysis in 3T3-L1 adipocytes. When treated with 100 μg/mL of 2,4,5-TMBA for 24, 48, or 72 h, the viability of fully differentiated 3T3-L1 adipocytes is decreased by 8.35, 15.54, and 27.26%, respectively. When the preadiocytes are treated with 100 μg/mL of 2,4,5-TMBA for 24 h before differentiation medium is supplemented, the cell viability is decreased by 26.46%[3]. Asaronaldehyde exhibited significant anti-Candida activity (P = 0.0412). Minimum inhibitory concentration (MIC) and minimum fungicidal concentration (MFC) were established as 0.25 and 0.5 mg/mL, respectively. It showed significant inhibition of hyphal form transition in yeast at MIC/2 and MIC/4 values[4].
