  • Abstract:Materials and methods:Non-toxic doses of teuclatriol were determined for both cell types by MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide)-assay. The effect of teuclatriol on the activity of NF-κB in LPS-stimulated human monocytic THP-1 cells was studied using infrared electrophoretic mobility shift assay (IR-EMSA) using curcumin as positive control (32μM). THP-1 were differentiated into macrophage-like cells and evaluated for TNF-α secretion by L929 bioassay following stimulation with LPS and treatment with teuclatriol. Inflammatory gene expression in human umbilical vein endothelial cells (HUVEC), modeling target cells for TNF-α-induced inflammatory gene activation, was investigated by real-time RT-PCR. Results:The LPS-induced DNA binding activity of NF-κB in THP-1 was significantly decreased by non-toxic doses of teuclatriol (312 and 390μM). Teuclatriol reduced the production of TNF-α in a dose-dependent manner. mRNA levels of both monocyte chemoattractant protein (MCP)-1 and toll-like receptor (TLR)2 were decreased in TNF-α-activated HUVEC. Conclusion:These data show an inhibitory effect of teuclatriol on NF-κB signaling at doses of 312μM and higher, validating the traditional use of Salvia mirzayanii in the treatment of inflammatory diseases. Future work on the mode of action of teuclatriol may provide new lead structures with NF-κB inhibiting properties, lacking possible side effects mediated via alkylating centers of sesquiterpene lactones.
