4-Methoxylonchocarpin is an orally active anti-inflammatory agent. 4-methoxylonchocarpin inhibits the binding of LPS to Toll-like Receptor (TLR) TLR4 to inhibit NF-kappaB activation and TNF Receptor and IL-6 expression. 4-Methoxylonchocarpin also inhibits the phosphorylation of TGF-beta activated kinase 1 and TNBS-induced expression of IL-1beta, IL-17A, and TNF. 4-methoxylonchocarpin can improve 2,4, 6-trinitrobenzene sulfonic acid (TNBS)-induced colitis mouse model[1].
