A prenylated cinnamic acid with diverse biological activities; selectively inhibits AKR1C3 (IC50 = 1 µM) over AKR1C1, AKR1C2, and AKR1C4 at 100 µM; inhibits lipid peroxidation in isolated human erythrocytes; induces calcium influx in HEK293T cells expressing human TRPA1 at 10 µM, an effect that can be blocked by HC-030031; cytotoxic to HT-1080 and 26-L5 cells (IC50s = 45.47 and 59.32 UG/ml, respectively); active against C. albicans, E. floccosum, T. rubrum, methicillin-sensitive S. aureus, and MRSA (MICs = 250, 50, 125, 250, and 250 UG/ml, respectively); decreases carrageenan-induced peritoneal leukocyte infiltration in mice at 1 and 10 mg/kg
