Non-communicable diseases like diabetes and cancer are the major cause of death worldwide. Various drugs are used for the treatment of these diseases. However, they cause lots of side effects. There is a need for alternate drugs with fewer side effects. Medicinal plants serve as a good source for alternate form of treatment. Therefore, in this study, ethanolic and aqueous extracts of D. regia flowers were evaluated for their antioxidant, antidiabetic, anti-inflammatory and cytotoxic activity to justify its use as a medicinal plant. Total phenol and flavonoid content of the extracts were measured. GC-MS analysis of the extracts were done to investigate the presence of various bioactive compounds. Antioxidant activity was assessed by radical scavenging and reduction assays. Antidiabetic activity was assessed by the ability of extracts to inhibit enzyme alpha amylase. Anti-inflammatory activity was evaluated by membrane stabilization activity. Anticancer activity against MCF-7 and A549 cell lines were measured by the MTT assay.The ethanolic extract contained more phenols (282.940.80 mgGAE/g) and flavonoids (140.912.27 mgQE/g). GC-MS analysis showed the presence of compounds belonging to fatty acids, alkanes, phenols and organic alcohols. The aqueous extract showed strong superoxide radical scavenging activity with a low IC50 of 39.35±0.74 µg/mL. The ethanolic extract showed higher ferric reducing power with an IC50 of 59.65±0.28µg/mL. Ethanolic extract was more potent in inhibiting alpha amylase with a low IC50 value of 47.14±0.6 µg/mL. Ethanolic extract also showed maximum inhibition of 88.86±0.1% against heat induced lysis of cell membrane. Both extracts affected the proliferation of MCF-7 and A549 cell lines at 160 µg/mL. The results of the present study support the use of D. regia flower as a potential source of bioactive phytochemicals and can be used as a plant-based antioxidant, antidiabetic, anti-inflammatory and anticancer agent.

Abstract Background Nymphaea lotus L. (N. lotus) is an aquatic plant with anecdotal reports suggesting its use in the traditional management of cancer. However, there is a paucity of data on the antioxidant, anti-inflammatory and cytotoxic properties of N. lotus in relation to its phytochemical and elemental contents. This study aimed at determining the antioxidant, anti-inflammatory and cytotoxic properties of the hydro-ethanolic extract of N. lotus leaves (NLE), and its phenolic, flavonoid and elemental constituents. Methods The antioxidant property of NLE was determined using total phenolic and flavonoid, DPPH radical scavenging, lipid peroxidation and reducing power assays. The anti-inflammatory activity of NLE (100–250-500 mg/kg), diclofenac and hydrocortisone (positive controls) were determined by paw oedema and skin prick tests in Sprague Dawley rats. Also, the erythrocyte sedimentation rate (ESR) was determined by Westergren method. The macro/micro-elements content was determined by the XRF method. The cytotoxic property of NLE was determined by the MTT assay, on two cancer cell lines (MCF-7 and Jurkat) and compared to a normal cell line (Chang liver). Inhibitory concentrations were determined as IC50 values (±SEM). Results The extract had appreciable levels of phenolic and flavonoids compounds and was two-fold more potent in scavenging DPPH radicals than Butylated hydroxytoluene (BHT). However, NLE was three- and six-fold less potent than ascorbic acid and BHT, respectively, in reducing Fe3+ to Fe2+. The extract was six-fold more potent than gallic acid in inhibiting lipid peroxidation. The extract caused a dose-dependent decrease in rat paw oedema sizes, comparable to diclofenac, and a significant decrease in wheel diameters and ESR. The elemental analysis revealed relevant concentrations of Mg2+, P2+, S2+, K2+, Mn+, Fe+, Cu+, Zn+ and Cd+. The extract exhibited cytotoxic activity on both MCF-7 (IC50 = 155.00 μg/ml) and Jurkat (IC50 = 87.29 μg/ml), with higher selectivity for Jurkat cell line. Interestingly, the extract showed low cytotoxicity to the normal Chang liver cell line (IC50 = 204.20 μg/ml). Conclusion N. lotus leaves extract exhibited high antioxidant, anti-inflammatory and cancer-cell-specific cytotoxic properties. These aforementioned activities could be attributed to its phenolic, flavonoid and elemental constituents. Graphical abstract

This study aims to investigate phytochemical screening, total polyphenol and flavonoids content, antioxidant activities and to examine toxicity, anti-inflammatory and antinociceptive effects of different extracts of stigmata of Zea mays from Morocco. The flavonoids and total phenols content were performed for both extracts. The aqueous and hydro-ethanolic extracts were screened for their possible antioxidant activities by three test systems, namely DPPH free radical-scavenging, reducing power and molybdenum system. Oral and Sub-acute toxicity of the hydro-ethanolic extract was evaluated in vivo. Anti-inflammatory activity of the hydro-ethanolic extract was evaluated by Carrageenaninduced rat paw edema method. The antinociceptive effect was tested by using the formalin test. Phytochemical screening of the extracts revealed a presence of flavonoids, leucoanthocyans, heterosid sterodic, coumarins, alkaloids, cardiac glycosides, anthocyanins and tannins. The flavonoids and total phenols content show higher content of flavonoids and total phenols in the hydro-ethanolic extract. It showed better antioxidant activity than the aqueous extract in the three methods used. Furthermore, the hydro-ethanolic extract with a concentration of 250 and 500 mg/kg body weight inhibited the inflammation induced by carrageenan in rats at 66.67% and 86.67% compared to 60.8% for indomethacin at 10 mg/kg after 5 h of inflammation induction. However, at dose of 500 mg/kg extract showed a pro-inflammatory effect. In the formalin test, the tolerance time of the rats was significantly higher compared to the control group. These initial results tend to support the traditional use in the treatment of cystitis, oliguria, nephritis, renal lithiasis edema, albuminuria, heart disease, slimming cures of stigmata of Zea mays in Morocco.

Objective: Synedrella nodiflora is traditionally used in the treatment of several ailments. Pharmacologically, this plant has anticonvulsant, sedative, anti-nociceptive and anti-proliferative effects. This study further investigated S. nodiflora for its antioxidant and in vitro inhibition of cancerous cell lines. Methods: Phytochemical assays, and the DPPH radical scavenging method were employed in preliminary screening for antioxidant activities of the crude hydro-ethanolic extract (SNE) and resulting fractions. The potent ethyl acetate fraction (EAF), was further investigated for total phenol and flavonoid contents, reducing power, lipid peroxidation potential, and cytotoxic effects on human breast cancer (MCF-7), leukemic (Jurkat), and normal liver (Chang’s liver) cell lines. Results: The extract contained phenols, flavonoids, tannins, glycosides, sterols, terpenoids, and alkaloids. It scavenged for DPPH with an IC50 of 114 µg/ml, whereas that of EAF was 8.9 µg/ml. EAF prevented peroxidation of egg lecithin at an IC50 of 24.01±0.08 µg/ml. These IC50s are four and three times lower than the reference standards. EAF produced anti-proliferative effects against MCF-7, and Jurkat cell lines with IC50s of 205.2 and 170.9 µg/ml, respectively. EAF had a high IC50 of 252.2 µg/ml against Chang’s liver cells. At 0.1 mg/ml EAF had similar total flavonoid content to SNE, but a significantly higher total phenol content. Conclusion: The ethyl acetate fraction of S. nodiflora, exhibited the most potent antioxidant activity. It inhibited the proliferation of breast and leukemic cancer cell lines, whiles having weak cytotoxic effect on normal liver cells. These can be explored for further drug development.

Background: NSAIDs are the most widely prescribed medications worldwide for their anti-inflammatory, antipyretic, and analgesic effects However, their chronic use can lead to several adverse drug events including GI toxicity. The selective COX-2 inhibitors developed as gastro-sparing NSAIDs also suffer from serious adverse effects which limit their efficacy. Objective: Local generation of reactive oxygen species is implicated in NSAID-mediated gastric ulceration and their combination with H2 antagonists like famotidine reduces the risk of ulcers. The objective of this work was to design and synthesize novel methanesulphonamido isoxazole derivatives by hybridizing the structural features of NSAIDs with those of antiulcer drugs (ranitidine, famotidine, etc.) to utilize a dual combination of anti-inflammatory activity and reducing (antioxidant) potential. Method: The designing process utilized three dimensional similarity studies and utilized an isoxazole core having a potential for anti-inflammatory as well as radical scavenging antioxidant activity. The compounds were assayed for their antiinflammatory activity in established in vivo models. The in vitro antioxidant activity was assessed in potassium ferricyanide reducing power (PFRAP) assay employing ascorbic acid as the standard drug. Results: Compounds (5, 6, 9 and 10) showed anti-inflammatory activity comparable to the standard drugs and were also found to be non-ulcerogenic at the test doses. Compounds 6-10 exhibited good antioxidant effect in the concentration range of 1.0-50.0 µmol/ml. The test compounds were also found to comply with the Lipinski rule suggesting good oral absorption. Conclusion: A new series of isoxazole based compounds is being reported with good anti-inflammatory activity coupled with antioxidant potential as gastro-sparing anti-inflammatory agents.
