Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Hippocratea africana root is used in African folk medicine for the treatment of several ailments, including pain and inflammation. AIM OF THE STUDY To isolate anti-inflammatory and analgesic compounds from the roots of H. africana, with accompanying antioxidant potentials. MATERIALS AND METHODS Dichloromethane, ethyl acetate, and aqueous fractions of H. africana roots, and isolated compounds from the bioactive ethyl acetate fraction were evaluated for anti-inflammatory and analgesic activities using the xylene induced oedema in mice and thermal induced pain models, respectively. The antioxidant potentials of isolated compounds were tested in 2,2-diphenyl-1-picryhydrazyl radical and ferric reducing antioxidant power assays. Structures were elucidated on the basis of spectroscopic analyses, including 1D and 2D NMR experiments, ionization mass spectrometry, and comparison with literature data. RESULTS Isoathyriol (1,3,7-trihydroxy-6-methoxyxanthone) and norathyriol (1,3,6,7-tetrahydroxyxanthone) were isolated from the potent anti-inflammatory and analgesic ethyl acetate fraction of H. africana roots. Isoathyriol and norathyriol demonstrated good anti-inflammatory, analgesic, and antioxidant properties compared with the standards used in each assay. CONCLUSIONS This study substantiates the use of H. africana root extract in the alleviation of inflammation and pain, and reports the characterization of secondary metabolites in H. africana and for the first time the presence of xanthones in Hippocratea genus.

Ameliorative effect of Homalium zeylanicum against carbon tetrachloride-induced oxidative stress and liver injury in rats. Biomed Pharmacother 2018; 111:305-314. [PMID: 30590318 DOI: 10.1016/j.biopha.2018.12.045] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/19/2018] [Revised: 11/16/2018] [Accepted: 12/12/2018] [Indexed: 12/11/2022] Open
Abstract
Objective is to evaluate the ameliorative effects of Homalium zeylanicum in carbon tetrachloride-induced oxidative stress and liver injury in rats. To establish the nature of antioxidant principles in the bioactive ethyl acetate fractions of bark (HZEB) and leaf (HZEL); oxygen radical absorbance capacity (ORAC) and cell-based antioxidant protection in erythrocytes (CAP-e) assays were performed. From acute toxicity study, HZEB and HZEL at 200 and 300 mg/kg b.w., were relatively safe at their effective doses. The degree of protection was measured by using biochemical parameters such as serum glutamate oxaloacetate transaminase (SGOT), serum glutamate pyruvate transaminase (SGPT), alkaline phosphatase (ALP), total bilirubin (TB) and total protein (TP) contents. Hepatic markers e.g. thiobarbituric acid reactive species (TBARS), superoxide dismutase (SOD), catalase (CAT) and reduced glutathione (GSH) were evaluated along with histopathological observations of liver tissues. Both fractions showed significant improvement in restoring SGOT, SGPT, ALP, TB and TP level. TBARS, SOD, CAT and GSH levels were significantly altered towards normal values. Both fractions at 300 mg/kg showed remarkable improvement in liver markers as compared to silymarin. Histopathological examinations showed reduction in hepatic necrosis and appeared normal hepatocellular architecture in HZEB and HZEL treated groups. In CAP-e assay, IC50 of HZEB (54.66 mg/mL) was higher than HZEL (60.88 mg/mL) and in ORAC assay, AUC of HZEB and HZEL were 33.46, 21.29 respectively and results were comparable with trolox. GC-MS and LC-MS analysis identified a total no. of 44 compounds. Few compounds were identified as bioactive compounds e.g. catechol (7.23%), tetraacetyl-d-xylonic nitrile (3%), oleic acid (0.49%), 2,6-bis(1,1-dimethylethyl)-phenol (3.71%), 3,4,5-trimethoxy-phenol (0.31%), and conifer alcohol (7.41%). The presence of antioxidant principles in both fractions were responsible for hepatoprotective activities, however, the presence of catechol (7.23%) in the bark part imparted better activities in protecting liver than leaf of H. zeylanicum.

Abstract
Paracetamol (APAP) is one of the most widely used and popular over-the-counter analgesic and antipyretic drugs in the world when used at therapeutic doses. APAP overdose can cause severe liver injury, liver necrosis and kidney damage in human beings and animals. Many studies indicate that oxidative stress is involved in the various toxicities associated with APAP, and various antioxidants were evaluated to investigate their protective roles against APAP-induced liver and kidney toxicities. To date, almost no review has addressed the APAP toxicity in relation to oxidative stress. This review updates the research conducted over the past decades into the production of reactive oxygen species (ROS), reactive nitrogen species (RNS), and oxidative stress as a result of APAP treatments, and ultimately their correlation with the toxicity and metabolism of APAP. The metabolism of APAP involves various CYP450 enzymes, through which oxidative stress might occur, and such metabolic factors are reviewed within. The therapeutics of a variety of compounds against APAP-induced organ damage based on their anti-oxidative effects is also discussed, in order to further understand the role of oxidative stress in APAP-induced toxicity. This review will throw new light on the critical roles of oxidative stress in APAP-induced toxicity, as well as on the contradictions and blind spots that still exist in the understanding of APAP toxicity, the cellular effects in terms of organ injury and cell signaling pathways, and finally strategies to help remedy such against oxidative damage.

Abstract
Acetaminophen (APAP) is a widely used analgesic and antipyretic drug. Generally, the therapeutic dose of APAP is clinically safe, however, high doses of APAP can cause acute liver and kidney injury. Therefore, the majority of previous studies have focussed on elucidating the mechanisms of APAP-induced hepatotoxicity and nephrotoxicity, in addition to examining ways to treat these conditions in clinical cases. However, few studies have reported APAP-induced intoxication in human stem cells. Stem cells are important in cell proliferation, differentiation and repair during human development, particularly during fetal and child development. At present, whether APAP causes cytotoxic effects in human stem cells remains to be elucidated, therefore, the present study aimed to investigate the cellular effects of APAP treatment in human stem cells. The results of the present study revealed that high-dose APAP induced more marked cytotoxic effects in human mesenchymal stem cells (hMSCs) than in renal tubular cells. In addition, increased levels of hydrogen peroxide (H2O2), phosphorylation of c-Jun N-terminal kinase and p38, and activation of caspase-9/-3 cascade were observed in the APAP-treated hMSCs. By contrast, antioxidants, including vitamin C reduced APAP-induced augmentations in H2O2 levels, but did not inhibit the APAP-induced cytotoxic effects in the hMSCs. These results suggested that high doses of APAP may cause serious damage towards hMSCs.
