1Ginsenoside Rg1 protects against transient focal cerebral ischemic injury and suppresses its systemic metabolic changes in cerabral injury rats显示文摘Ginsenoside Rg1(GR),a major bioactive compound of traditional Chinese medicine,such as Panax ginseng or Radix Notoginseng,has been shown to exert neuroprotective effects against ischemic stroke.However,pharmacokinetic studies have suggested that GR could not be efficiently transported through the blood–brain barrier.The mechanism by which GR attenuates cerebral ischemic injury in vivo remains largely unknown.Therefore,this study explored potential neuro-protective effects of GR through its systemic metabolic regulating mechanism by using mass spectrometry–based metabolomic profiling.Rats with middle cerebral artery occlusion(MCAO) were treated with GR intravenously.Their metabolic profiles in serum were measured by gas chromatography coupled with mass spectrometry on 1 and 3 days after MCAO.GR exhibited a potent neuro-protective effect by significantly decreasing the neurological scores and infarct volume in the MCAO rats.Moreover,18 differential metabolites were tentatively identified,all of which appeared to correlate well with these disease indices.Our findings suggested that GR carries a therapeutic potential in stroke possibly through a feed-back mechanism by regulating systematic metabolic mediation.Mingbao Lin Wei Sun Wan Gong Yasi Ding Yuanyan Zhuang Qi Hou 2015Acta Pharmaceutica Sinica B2015,5,3:7

8Product identification and toxicity change during oxidation of methotrexate by ferrate and permanganate in water显示文摘Accompanying an annual increase in cancer incidence,the global use of anticancer drugs has remarkably increased with their worldwide environmental prevalence and ecological risks.In this study,the oxidation of methotrexate(MTX),a typical anticancer drug with ubiquitous occurrence and multi-endpoint toxicity,by ferrate(VI)(Fe(VI))and permanganate(Mn(VII)))was investigated in water.Fe(VI)exhibited a higher reactivity with MTX(93.34 M^(−1) s^(−1))than Mn(VII)(3.01 M^(−1) s^(−1)) at pH 8.0.The introduction of Cu(II)and Fe(III)at 1.0 mM improved the removal efficiency of 5.0μM MTX by 100.0μM Fe(VI)from 80%to 95%and 100%after 4 min,respectively.Seven oxidized products(OPs)were identified during oxidative treatments,while OP-191 and OP-205 were characterized as specific products for Fe(VI)oxidation.Initial ketonization of the L-glutamic acid moiety and cleavage of the peptide bond of MTX were proposed.Additionally,a multi-endpoint toxicity evaluation indicated no genotoxicity,neurotoxicity,or endocrine-disrupting effects of MTX and its OPs.Particularly,serious developmental toxicity in zebrafish larvae was observed in the treated MTX solutions.Based on the acute and chronic aquatic toxicity prediction,OP-190,OP-192,OP-206,and OP-208 were deemed toxic or very toxic compared to harmful MTX.Furthermore,the reduced biodegradability index from 0.15(MTX)to−0.5 to−0.2(OP-192,OP-206,and OP-468)indicated the formation of lower biodegradable OPs.Overall,this study suggests that Fe(VI)and Mn(VII)oxidation are promising treatments for remediating anticancer drug-contaminated water.However,the environmental risks associated with these treatments should be considered in the evaluation of water safety.Shengqi Zhang Chengsong Ye Wenjun Zhao Lili An Xin Yu Lei Zhang Hongjie Sun Mingbao Feng 2022Frontiers of Environmental Science & Engineering2022,16,7:0
