(-)-Arctiin

Isolated from Arctium lappa. Soluble in DMSO (20mg/ml), DMF (20mg/ml) or ethanol (1mg/ml). Insoluble in water. Metabolizes into (-)-Arctigenin (AG-CN2-0530). Multifunctional natural compound with photoprotective, anti-inflammatory, antidiabetic, antiproliferative and antiviral activities. Decreasing the production of nitric oxide and pro-inflammatory cytokines, such as IL-1beta, IL-6, TNF-alpha and PGE2 through the inhibition of PI3K/AKT/NF-kappaB signaling pathway. Suppresses cyclin D1 protein expression in multiple types of human tumor cells. Inhibitor of HIV-I integrase. Inhibits adipogenesis in 3T3-L1 adipocytes through the inhibition of PPARgamma and C/EBPalpha and the activation of AMPK signaling pathways. Photoprotective agent showing UVB protection in keratinocytes, which is mediated by miRNA responses and the suppression of UVB-induced cell death. Inhibitor of STAT3 phosphorylation at tyrosine 705 residue.
