PG - 606-615 LID - S0753-3322(18)31607-X [pii] LID - 10.1016/j.biopha.2018.06.019 [doi] AB - Solanine A is a novel steroidal alkaloid isolated from Solanum nigrum Linn., a medicinal and edible plant which is widely used for treating various inflammatory diseases. In this study, we found that solanine A markedly suppressed the production of nitric oxide (NO) and prostaglandin E(2) (PGE(2)) in lipopolysaccharide/interferon-gamma (LPS/IFNgamma)-stimulated RAW264.7 cells, and attenuated xylene, carrageenan and agar-induced inflammation in mice. The mRNA levels of inducible nitric oxide synthase (iNOS), cyclooxygenase-2 (COX2), tumor necrosis factor-alpha (TNF-alpha), interleukin-6 (IL-6), and -1beta (IL-1beta), as well as C-X-C motif chemokine ligand-9 (CXCL9), were significantly decreased by solanine A. Furthermore, solanine A also suppressed LPS/IFNgamma-induced protein expression of iNOS and COX2. Mechanistically, solanine A inhibited the nuclear translocation of nuclear factor-kappaB (NF-kappaB) through the prevention of NF-kappaB p65 and inhibitory kappaB-alpha (IkappaBalpha) phosphorylation and IkappaBalpha degradation, and it also suppressed activation of extracellular regulated protein kinases (ERK), signal transducers and activators of transcription-1 (STAT1) and serine/threonine protein kinase Akt in LPS/IFNgamma-stimulated RAW264.7 macrophages and agar-induced granuloma model in mice. Taken together, solanine A exhibits a potent anti-inflammatory activity in LPS/IFNgamma- activated macrophages and animal models of inflammation through inhibition of NF-kappaB, ERK1/2, Akt and STAT1 signaling pathways, suggesting that solanine A may be a valuable leading compound in the treatment of inflammatory diseases.
