Azima Tetracantha

Plant-derived antioxidants are a large group of natural products with the capacity to reduce radical-scavenging. Due to their potent therapeutic and preventive actions, these compounds receive a lot of attention from scientists, particularly pharmacologists. The pharmacological activities of the Azima tetracantha Lam. (AT) plant, belonging to the Salvadoraceae family, reported here justifies its traditional use in treating several diseases or disorders. This study aims to look at the propensity of certain plant compounds found in natural AT plant extracts that might play a critical role as a secondary metabolite in cervical cancer treatment. There is a shortage of information on the plant’s phytochemical and biological characteristics. Methanol (MeOH) solvent extracts of the dried AT plant were screened phytochemically. Its aqueous extract was tested for antioxidant, antiseptic, anti-inflammatory, and anticancerous properties. Absorption Distribution Metabolism and Excretion (ADME/T), Docking, and HPLC were also performed. In clinical treatment, the plant shown no adverse effects. The antioxidant activity was evaluated and showed the highest concentration at 150 µg/mL (63.50%). MeOH leaf extract of AT exhibited the highest and best inhibitory activity against Staphylococcus aureus (15.3 mm/1000) and displayed a high antiseptic potential. At a 200 µg/mL concentration, MeOH leaves-extract inhibited red blood cells (RBC) hemolysis by 66.56 ± 0.40, compared with 62.33 ± 0.40 from the standard. Albumin’s ability to suppress protein denaturation ranged from 16.75 ± 0.65 to 62.35 ± 0.20 inhibitions in this test, providing even more support for its favorable anti-inflammatory properties. The ADME/T studies were considered for a potential cancer drug molecule, and one of our compounds from MeOH extract fills the ADME and toxicity parameters. The forms of compound 4 showed a strong hydrogen-bonding interaction with the vital amino acids (ASN923, THR410, LEU840TRY927, PHE921, and GLY922). A total of 90% of cell inhibition was observed when HeLa cell lines were treated with 300 µg/mL of compound 4 (7-acetyl-3a1-methyl- 4,14-dioxo-1,2,3a,3a1,4,5,5a,6,8a,9b,10,11,11a-tetradecahydro-2,5a epoxy5,6a (methanooxymethano)phenaleno[1′,9′:5,6,7]indeno[1,7a-b]oxiren-2-yl acetate). The polyphenol compounds demonstrated significant advances in anticancer drug properties, and it could lead to activation of cancer cell apoptosis.

Arthrophytum scoparium is plant commonly used in folk medicine in Algeria to treat numerous human diseases especially infectious, Rheumatism, diabetes and cancer. However, its anti-inflammatory activity and the underlying mechanisms have not been studied systematically. The present study aims to assess both the in vitro and in vivo anti-inflammatory potential and antioxidant activity of the plant. Results showed that A. scoparium chloroform extract (ChE) contains the largest amount of phenolic and flavonoid compounds. In-vitro bioassay consisted of investigating the effect of the plant extracts against protein denaturation (BSA and egg albumin). In-vivo anti-inflammatory activity was evaluated by measuring the percentage inhibition of carrageenan-induced rat paw edema after oral administration of the extracts. Results showed that inhibition of protein denaturation was maximum in case of A. scoparium crude extract (CrE) with dose dependant manner. Similarly in the in-vivo study, carrageenan induced inflammation was significantly antagonized by CrE with inhibition of 87.02% at 400 mg/kg. CrE extracts showed the highest scavenger effect against hydroxyl and hydrogen peroxide. The CrE showed potent anti-inflammatory activity in both the conditions in vivo and in vitro. In conclusion different A. scoparium extracts scavenged reactive oxygen species efficiently; it may be due to the presence of its flavonoids and polyphenols. These results support the traditional use of this plant. Keywords: Arthrophytum scoparium, polyphenols, anti-inflammatory activity, radical scavenging activity.

Honey and propolis are natural substances produced by Apis mellifera that contain flavonoids, phenolic acids, and several other phytochemicals. The aim of this study was to phytochemically characterize three different types of honey and propolis, both separately and mixed, and to evaluate their wound-healing activity. Total phenolic compounds and flavonoids were determined using the Folin–Ciocalteu’s and aluminum chloride colorimetric methods, respectively. The antioxidant activity was evaluated by both the DPPH free radical scavenging assay and β-carotene bleaching test, and the anti-inflammatory activity was determined by a protein denaturation method. To evaluate the wound-healing activity of the samples, NHDF cells were subjected to a wound scratch assay. The obtained results showed that dark-brown honey presents a higher concentration of phenolic compounds and flavonoids, as well as higher antioxidant and anti-inflammatory activities. Propolis samples had the highest concentrations in bioactive compounds. Examining the microscopic images, it was possible to verify that the samples promote cell migration, demonstrating the wound-healing potential of honey and propolis.

Abstract Oxidative stress is a critical etiologic factor and driver of inflammatory responses, witnessed in chronic and persistent conditions. The current anti-oxidative stress and anti-inflammatory drugs are associated with detrimental effects, high dependence, high costs, inaccessibility, among other drawbacks; therefore, a need for alternatives is imperative. Despite the remarkable potential of medicinal plants, there are scanty empirical studies on their pharmacologic efficacy. The Phytexponent is an alcoholic polyherbal preparation of Allium sativum, Triticum repens, Echinacea purpurea, Viola tricolor and Matricaria chamomilla. In complementary medicine, the Phytexponent is used to boost immunity, to treat inflammatory disorders, oxidative stress, blood pressure, diabetes, stress/depression, among other conditions. However, there is no sufficient scientific data to support these healing claims. Therefore, in the current study evaluated the in vitro anti-inflammatory, antioxidant activities and qualitative phytochemical composition of the Phytexponent. The in vitro anti-inflammatory activities were evaluated using the inhibition of protein denaturation and the human erythrocyte (HRBC) membrane stabilization techniques. Antioxidant activities were evaluated by the 1,1-diphenyl-picryl-1-hydrazyl (DPPH) radical scavenging-, the hydroxyl radical scavenging- and catalase activities. Qualitative phytochemical screening was performed using standard procedures. The results showed a significantly higher percentage inhibition of heat-induced- and hypotonicity induced HRBC hemolysis by the Phytexponent at concentrations of 50 % and 100 %, compared with the percentage inhibitions of etanercept (p<0.05). No significant differences in percentage inhibitions of protein denaturation were observed among concentrations of 12.5 %,25.0 %,50.0 %,100.0 % of the Phytexponent and etanercept (25 mg/ml) (p˃0.05). Furthermore, the Phytexponent demonstrated high antioxidant activities against the DPPH- (IC50=0.00733%) and the hydroxyl- (IC50 = 0.716 %) radicals in vitro.The Phytexponent recorded significantly higher catalase activities at concentrations of 1 % and 0.1 % than those recorded by ascorbic acid at similar concentrations. Qualitative phytochemical screening revealed the presence of phenols, flavonoids, tannins, among other antioxidant associated phytochemicals. The bioactivities of the Phytexponent reported herein, were attributed to the presence of these phytochemicals. Further studies to establish specific mode(s) through which the Phytexponent exerts in vitro anti-inflammatory and antioxidant effects are encouraged. Moreover, in vivo anti-inflammatory and antioxidant activities should be done to determine the replicability of these findings in vivo. Bioassay-guided isolation of compounds responsible for the reported bioactivities herein should be done.

Euphorbia hirta L (Euphorbiaceae) also called asthma herb has long been prescribed in traditional medicine because it exhibits diverse pharmacological actions due to the presence of alkaloids, flavonoids, polyphenols, triterpenoids, and saponins. The present study is aimed at the study of phytochemical and antioxidant activity and anti-inflammatory screening of E. hirta. Extraction of dried powder was performed followed by phytochemical screening using color reactions. Total phenolic content (TPC) and total flavonoid content (TFC) of the extracts were estimated by Folin-Ciocalteu and Aluminum chloride method respectively. The antioxidant activity was studied by the 2,2-diphenyl-1-picrylhydrazyl (DPPH) free radical scavenging method.  Anti-inflammatory activity was studied by using protein denaturation in vitro bioassay. Phytochemical screening showed the presence of flavonoids, alkaloids, and phenolic compounds. TPC, TFC and antioxidant activity (IC50) of the extract were found as 288.10 mg gallic acid equivalent per gram (GAE/g), 29.36 mg quercetin equivalent per gram (QE/g) and 32.23 µg/mL (p<0.05) respectively. Diclofenac sodium and E. hirta extract showed the maximum inhibition of 91.28% and 68.20% respectively at the concentration of 1000 µg/mL compared with control (p>0.05). The phenolic compounds and flavonoids exert antioxidant and anti-inflammatory activities because of their scavenging ability. The demonstrated antioxidant and anti-inflammatory activities may be the rationale behind some of its folkloric uses and also may be responsible for some of its pharmacological effects. Thus, E. hirta can be considered a good source of antioxidants and anti-inflammatory actions, which might be beneficial for combating oxidative stress.

Abstract Abstract In the treatment of cancer, patients that receive anti-cancer drugs such as Vincristine develop peripheral neuropathic pain. Scyphocephalione A is a new bioactive compound isolated from Scyphocephalium ochocoa (Myristicaceae), a medicinal plant traditionally used in African countries. Recently, an in vitro study has shown its anti-inflammatory and cytotoxic activities on MCF-7 cell line of mammary carcinoma. The purpose of the present study was to assess the in vitro anti-inflammatory and in vivo anti-nociceptive activities of Scyphocephalione A. In vitro tests were carried out on cyclooxygenase and 5-lipoxygenase activities, and on protein denaturation; while in vivo tests were performed on acute and chronic pain models. It was noticed that, Scyphocephalione A (1000 µg/ml), inhibits proteins denaturation, cyclooxygenase and 5-lipoxygenase activities respectively by 74.21%, 75.80% and 64.43%. The dose 50 mg/kg of Scyphocephalione A, inhibits acetic acid (63.43%, p<0.001) and formalin (42.12% (p<0.001) within first phase and 67.53% (p<0.001) within second phase)-induced pains. At the same dose, Scyphocephalione A significantly inhibited mechanical and heat hyperalgesia, as well as cold allodynia induced by vincristine. In addition, the compound restored haematological, biochemical and oxidative stress parameters which were altered following Vincristine administration. These results suggest that Scyphocephalione A is endowed with anti-inflammatory potential and antinociceptive properties. Therefore, Scyphocephalione A can be classified as a promising molecule for the management of peripheral neuropathic pain triggered by anti-cancer drug.
