Anti-inflammatory components of the Vietnamese starfish Protoreaster nodosus

Abstract: BackgroundIn the present study, we examined the inhibitory effects of a methanolic extract, dichloromethane fraction, water layer, and polyhydroxylated sterols (1–4) isolated from the Vietnamese starfish Protoreaster nodosus on pro-inflammatory cytokine (IL-12 p40, IL-6, and TNF-α) production in LPS-stimulated bone marrow-derived dendritic cells (BMDCs) using enzyme-linked immunosorbent assays (ELISA).ResultsThe methanolic extract and dichloromethane fraction exerted potent inhibitory effects on the production… Show more

“…998 Polyhydroxylated sterols from the Vietnamese urchin Diadema savignyi induce apoptosis in HTCLs via inactivation of the MAPK/ERK1/2 pathway 999 while sterols from the starsh Protoreaster nodosus were found to inhibit the production of pro-inammatory cytokines including IL-12 p40, IL-6 and TNF-a in LPS-stimulated bone marrow-derived dendritic cells. 1000 Puried saponins from Chinese collections of Holothuria moebii exhibited in vitro cytotoxicity towards a panel of HTCLs and a total saponin fraction (mixture) inhibited CT-26 tumour growth in mice. 1001 In a detailed study, the triterpene glycoside stichoposide D (Thelenota anax) was found to induce apoptosis in vitro in human leukemia cells through activation of CerS6 (ceramide synthase) and p38 kinase, and that similar activation properties were observed in vivo towards HL-60 and K562 xenogras.…”
