delta-Amyrone inhibits lipopolysaccharide-induced inflammatory cytokines and protects against endotoxic shock in mice.[Pubmed:26271896]
Chem Biol Interact. 2015 Oct 5;240:354-61.
delta-Amyrone (13(18)-Oleanen-3-one), which is an active constituent extracted and separated from Sedum lineare Thunb., has been found to possess a potent anti-inflammatory effect in different inflammation model animals. But its effects on lipopolysaccharide (LPS)-induced endotoxic shock have not been previous explored. The aim of this study is to evaluate the effect of delta-Amyrone on LPS-induced inflammatory cytokines and the protective effect on endotoxic shock mice. Experimental animals received delta-amyrone (4 and 8 mg/kg, i.p.) and dexamethasone (DEX) (5 mg/kg, i.p.) at 24 and 1 h before LPS injection. delta-Amyrone treatment significantly decreased mortality rate, tissues myeloperoxodase (MPO) activity, p65 NF-kappaB protein expression when compared with the LPS groups. The levels of tumor nectosis factor-alphagene (TNF-alpha) and interleukin-6 (IL-6) both in serum and lung, liver, kidney tissues, as well as the accumulation of nitric oxide (NO) in serum were decreased by delta-amyrone in response to p65 nuclear factors-kappa B (NF-kappaB). These results suggest that the protective activity of delta-amyrone on LPS-induced endotoxic shock is attributed to reducing NO production and mediating the pro-inflammatory cytokines, inhibited NF-kappaB expression.
Protective effect of delta-amyrone against ethanol-induced gastric ulcer in mice.[Pubmed:25572867]
Immunobiology. 2015 Jun;220(6):798-806.
The purpose of this study is to examine the protective effect of delta-amyrone on ethanol-induced gastric ulcer in mice. The mice intragastric administration 75% (0.5 mL/100g) ethanol was pretreated with delta-amyrone (4 and 8 mg/kg) and cimetidine (100 mg/kg) or vehicles in different experimental groups for a continuous three-day, and animals were euthanized 3h after ethanol ingestion. The gastric lesions were significantly attenuated by delta-amyrone (4 and 8 mg/kg) as compared to the ulcer control group. Pre-treatment with delta-amyrone prevented the myeloperoxidase (MPO) activity, production of nitric oxide (NO) in serum, expression of inducible nitric oxide synthase (iNOS) and nuclear factor kappa B (NF-kappaB) p65 protein expression. Analysis of cytokines in gastric tissue and serum of ethanol-induced mice showed the levels of tumor necrosis factor-alpha (TNF-alpha) and interleukin-6 (IL-6) were decreased by delta-amyrone in response to NF-kappaB p65. These results suggested that delta-amyrone exerts its protective effect on experimental gastric ulcer by inhibiting NF-kappaB signaling pathways, which subsequently reduces overproduction of the inducible enzymes iNOS and suppresses the release of the inflammatory factors TNF-alpha, IL-6 and NO. Thus, delta-amyrone shows promise as a therapeutic agent in experimental gastric ulcer.
delta-Amyrone, a specific inhibitor of cyclooxygenase-2, exhibits anti-inflammatory effects in vitro and in vivo of mice.[Pubmed:24813716]
Int Immunopharmacol. 2014 Jul;21(1):112-8.
The whole plant of Sedum lineare Thunb has been used as traditional folk medicines for the treatment of sore throat, persistent hepatitis, jaundice and dysentery. delta-Amyrone (13(18)-Oleanen-3-one), a pentacyclic triterpene compound from S. lineare Thunb, was found to possess a potent anti-inflammatory effect in different inflammation model animals. Pretreatment with delta-Amyrone (i.p.) inhibited the ear edema in xylene-induced mouse ear edema. delta-Amyrone also decreased the level of nitric oxide (NO), prostaglandin E2 (PGE2), interleukin-6 (IL-6) and leukocyte numbers in acetic acid-induced peritonitis in vivo. To clarify the possible mechanism of delta-Amyrone, we investigated the effect of delta-Amyrone in lipopolysaccharide (LPS) induced peritoneal macrophages. The data indicated that delta-Amyrone notably inhibited IL-6, TNF-alpha and NO production. In addition, the result showed that delta-Amyrone may control the cyclooxygenase-2 (COX-2) regulation and not the cyclooxygenase-1 (COX-1) at protein levels. These results suggest that delta-Amyrone is a bioactive agent which possesses anti-inflammatory effects, which may be relevant to the regulation of COX-2.
