    Neferine, an alkaloid ingredient in lotus seed embryo, inhibits proliferation of human osteosarcoma cells by promoting p38 MAPK-mediated p21 stabilization.[Pubmed: 22227330 ]
    Identification of natural products that have antitumor activity is invaluable to the chemoprevention and therapy of cancer. The embryos of lotus (Nelumbo nucifera) seeds are consumed in beverage in some parts of the world for their presumed health-benefiting effects.
    In this report we studied the effects of neferine, a major alkaloid component in lotus embryos, on human osteosarcoma cells and the underlying mechanisms. We found that neferine possessed a potent growth-inhibitory effect on human osteosarcoma cells, but not on non-neoplastic human osteoblast cells. The inhibitory effect of neferine on human osteosarcoma cells was largely attributed to cell cycle arrest at G1. The induction of G1 arrest was p21(WAF1/CIP1)-dependent, but was independent of p53 or RB (retinoblastoma-associated protein). The up-regulation of p21 by neferine was due to an increase in the half-life of p21 protein. We examined four kinases that are known to affect the stabilization of p21, and found that p38 MAPK and JNK were activated by neferine. However, only SB203580 (an inhibitor of p38), but not SP600125 (the inhibitor of JNK), can attenuate the up-regulation of p21 in response to neferine. Furthermore, the p21-stabilizing effect of neferine was abolished when p38 was silenced by RNA interference. Finally, we showed that neferine treatment led to an increased phosphorylation of p21 at Ser130 that was dependent on p38.
    Our results for the first time showed a direct antitumor effect of neferine, suggesting that consumption of neferine may have cancer-preventive and cancer-therapeutic benefit.

    Neferine prevents NF-κB translocation and protects muscle cells from oxidative stress and apoptosis induced by hypoxia[Pubmed: 27041079]
    Abstract Neferine (Nef), a bisbenzylisoquinoline alkaloid from lotus seed embryo has a wide range of pharmacological activities. Possible molecular mechanism for the cytoprotective action of Nef during hypoxic stress has not been explored till now. Hence, this is an attempt to elucidate the molecular mechanism involved in the Nef mediated cytoprotection on hypoxia-induced cell injury. Cytoprotective dose of Nef in muscle cells (Human rhabdomyosarcoma cells) exposed to hypoxia was determined by MTT assay. Nef at 500 nM offered better cytoprotection and was used for all the experiments. ROS, intracellular calcium accumulation and mitochondrial membrane (ΔψM) potential were measured using fluorescent probes. Further, we evaluated the effect Nef on hypoxia induced inflammatory and apoptotic responses by FACS and analyzing the expression patterns of NF-κB, COX-2, HIF-1α, caspase-3, caspase-9, Bcl2, and Bax. The results of this study revealed that pretreatment of the cells with Nef significantly decreased the ΔψM and ROS in the cells subjected to hypoxia. Further, Nef inhibited NF-κB there by inhibiting the expression of its downstream regulator COX-2, while it induced the functional HIF-1α expression. The results also indicate that Nef significantly inhibited the ROS dependent mitochondrial mediated apoptosis induced during hypoxia. The cytoprotection elicited by Nef in a model of hypoxia induced cell death involves both anti-inflammatory and anti-apoptotic response. These results suggest that Nef may be used as prophylactic agent against the hypoxic challenge. © 2016 BioFactors, 42(4):407-417, 2016.

    Neferine enhances insulin sensitivity in insulin resistant rats.[Pubmed: 19527823 ]
    Neferine was isolated from green seed embryo of Nelumbo nucifera Gaertn which has been used as an anti-obesity agent in traditional Chinese herbal medicine. This study was conducted to investigate the effects of neferine on enhancing insulin sensitivity in insulin resistant rats compared with rosiglitazone and to potentially reveal its role in mediating the anti-obesity properties of Nelumbo nucifera Gaertn.
    Fasting blood glucose (FBG), fasting blood insulin (FINS), triglycerides (TG) and tumor necrosis factor-alpha (TNF-alpha) were measured, and the oral glucose tolerance test for 2-h plasma glucose level (2-h PG) was carried out. The glucose infusion rate (GIR) was used to measure the insulin sensitivity by hyperinsulinemic euglycemic clamp technique. The levels of FBG, FINS, TG, TNF-alpha and 2-h PG all decreased significantly in the rosiglitazone and neferine groups compared with the insulin resistance (IR) model group. Neferine diminished the 2-h PG more than did rosiglitazone treatment. Compared to the IR model group, the treatments of neferine and rosiglitazone remarkably increased GIRs but no difference between these two treatments themselves was evident.
    These data demonstrate that neferine has effects similar to rosiglitazone in decreasing fasting blood glucose, insulin, TG, TNF-alpha and enhancing insulin sensitivity in insulin resistant rats.

    Effects of extracts and neferine from the embryo of Nelumbo nucifera seeds on the central nervous system.[Pubmed: 19010651 ]
    The effects of embryos of the seeds of Nelumbo nucifera on the central nervous system were studied in mice.
    MeOH extracts of embryos of Nelumbo nucifera seeds significantly inhibited locomotor activity in mice. The MeOH extract was successively partitioned between H(2)O and n-hexane, between H(2)O and CHCl(3), and between H(2)O and n-BuOH. CHCl(3) extracts strongly inhibited locomotor activity in mice, although other extracts had no effect on locomotor activity. The main alkaloid of CHCl(3) extracts, neferine, dose-dependently inhibited locomotor activity in mice. Neferine induced hypothermia in mice and apparently potentiated thiopental-induced sleeping time. An anxiolytic, diazepam, decreased locomotor activity, rectal temperature and enhanced sleep elicited by thiopental, similar to neferine. In addition, neferine and diazepam showed anti-anxiety effects in the elevated plus maze test. Neferine did not affect muscle coordination by the rota-rod test. Neferine did not affect strychnine- nor picrotoxin-induced seizure. In contrast, diazepam had apparent muscle relaxant and anti-convulsant effects.
    These results suggest that neferine has several central effects and that neferine may participate in the efficacy of the sedative effects of embryos of the seeds of Nelumbo nucifera. The mechanisms of the sedative effects of neferine are not similar to those of diazepam.

    Protective effect of neferine against isoproterenol-induced cardiac toxicity.[Pubmed: 23274852 ]
    The present study was designed to investigate the cardioprotective effect of neferine against isoproterenol-induced myocardial infarction.
    Neferine was given orally for 30 days, and isoproterenol was injected subcutaneously for 2 days. Histopathological examination of heart tissue of isoproterenol-treated rats showed myocardial necrosis. Biochemical analysis of isoproterenol-treated rats showed significant increase in the serum marker enzymes--creatine kinase, lactate dehydrogenase, and aspartate transaminase and increased serum glycoprotein components with a concomitant decrease in the heart tissue homogenate when compared to control. Increased lipid peroxidation and decreased antioxidants reduced glutathione, superoxide dismutase, catalase, glutathione-S-transferase, glutathione peroxidase and altered lipid profile in serum and tissue was also recorded in the isoproterenol-treated rats, whereas the rats which received neferine pre-treatment followed by isoproterenol injection showed minimal histological changes, absence of inflammation, and a significant decrease in the serum marker enzymes and serum glycoprotein components with a concomitant increase in the heart tissue homogenate when compared to isoproterenol group. Neferine pre-treatment restored the altered biochemical parameters and lipid profile to near normal.
    The results of the present study showed that neferine exerts strong antioxidant property against isoproterenol-induced oxidative stress and can be used as a potent cardioprotective agent against isoproterenol-induced myocardial infarction.

    Neferine inhibits proliferation and collagen synthesis induced by high glucose in cardiac fibroblasts and reduces cardiac fibrosis in diabetic mice[Pubmed: 27533252]
    Abstract Cardiac fibrosis is a common pathological process accompanying diabetes mellitus. In this report, we studied the effects of neferine (a major bisbenzylisoquinline alkaloid derived from lotus embryos) on cardiac fibrosis induced by diabetes mellitus, as well as the underlying molecular pathways. In vivo, type 1 diabetes mellitus was induced in mice by administering streptozotocin. Diabetic mice were treated with neferine through oral gavage, and cardiac function was assessed using echocardiography. Total collagen deposition was assessed by Masson's trichrome and Picrosirius staining. In vitro, cardiac fibroblasts were cultured in normal or high-glucose medium with or without neferine. Neferine attenuated left ventricular dysfunction and remodeling and reduced collagen deposition in diabetic mice. In vitro, neferine inhibited cardiac fibroblast proliferation, migration, and differentiation into myofibroblasts. In addition, neferine reduced high-glucose-induced collagen production and inhibited TGF-β1-Smad, ERK and p38 MAPK signaling activation in cardiac fibroblasts. These results suggest that neferine may have antifibrogenic effects in diabetes-related cardiac fibrosis.
