In Vitro Anticancer and Cytotoxic Activity of Ethanolic Extract of Phyllanthus reticulatus Poir. Against Hela Cell Line and Vero Cell Line

The present study was designed to investigate the anticancer activity of Phyllanthus reticulatus Poir. against HeLa cell line and to predict the therapeutic potential by investigating the cytotoxicity of the extract against Vero cell line and determining the selectivity index (SI). Phytochemical screening of the ethanolic extract of Phyllanthus reticulatus Poir. was employed by using standard methods. Anticancer and cytotoxic activities were investigated from Centre for Advanced Research in Science using their commercial services. MTT assay was employed for the evaluation of the activities. The concentrations of the extract was 5 mg/ml, 2.5 mg/ml, 1.25 mg/ml and 0.625 mg/ml. From the survival rate % inhibition was calculated and graphically the IC50 value was determined by plotting the % inhibition against the concentration of the extract investigated. Finally, the selectivity index was calculated from the IC50 values of the extract against HeLa cell line and Vero cell line. Glycoside, tannin, alkaloid, flavonoid, phenol, coumarin were present in the ethanolic extract of Phyllanthus reticulatus Poir. The IC50 value of the extract against HeLa Cell and Vero Cell were 1.00 mg/ml and 8.09 mg/ml respectively. The selectivity index was 8.09. This value indicates that the cancer cell (HeLa cells) will be killed at higher rate than normal ones i.e. the extract is more toxic for cancer cells.

Recycled Pequi (Caryocar brasiliense, Camb.) Shell Ethanolic Extract Induces Apoptosis in Canine Osteosarcoma Cells

Abstract Osteosarcoma is a mesenchymal cancer associated with high mortality in dogs and in humans. The biodiversity-rich Cerrado, the predominant biome in the Midwest region of Brazil, is native to locally appreciated fruits such as pequi (Caryocar brasiliense, Camb). Although this plant has been frequently used in folk medicine, the pharmacological properties of pequi fruit shells have not been fully evaluated. Thus, this study aimed to determine the cytotoxic activity of ethanol extract of recycled pequi shells on canine osteosarcoma cells in vitro. Cells were cultured and treated with final extract concentrations of 0, 0.029 µg/µL, 0.29 µg/µL, and 2.91 µg/µL for 24, 48, or 72 hours. Cell viability assay using trypan blue exclusion method and tetrazolium reduction method, cell survival assay, and double labeling with annexin V and propidium iodide were performed in the treated osteosarcoma cells. These allowed the determination of IC50, survival fraction, and type of cell death, respectively. Pequi shell ethanol extract at a concentration of 2.91 µg/µL showed the greatest inhibition of osteosarcoma cell growth in vitro, resulting in a 71.80% decrease in growth compared to the control. The mean IC50 was 155.2 μg/mL at 72 hours. The calculated survival fractions showed that cell growth at 72 hours was 3.33% lower in cells treated with 2.91 µg/µL extract. Results from the double labeling experiment suggest that apoptosis was the predominant type of cell death in cells treated with 2.91 µg/µL extract. These results demonstrate that ethanol extract of recycled pequi shells promotes apoptosis in canine osteosarcoma cells.

Aloe saudiarabica and Aloe shadensis are a rare species of the genus Aloe found only in Saudi Arabia. The cytotoxic activity of both plants were evaluated in the current study using three different human cancer cell line, lung carcinoma (A-549), breast adenocarcinoma (MCF-7) and liver cancer (HepG2), assessed by WST-1 cell viability assays. The results indicate that the Aloe saudiarabica and Aloe shadensis showed weak cytotoxic effects against all three tested cancer cell lines, with an IC50 value of >300 μg/ml. In addition, HepG2 cells were more sensitive to Aloe saudiarabica treatment than MCF-7 and A549 cells, while MCF-7 cells were more sensitive to Aloe shadensis treatment than HepG2 and A549 cells. This study also identified the characteristic chemical constituents of the two plants using gas chromatography-mass spectrometry technique and the result indicated that 9-octadecenoic acid (Z)-, methyl ester (32.23%) was the main compound of Aloe saudiarabica while methyl 9-octadecenoate (17.28%) was the main compound of Aloe shadensis. In conclusion, the in vitro evaluation of Aloe saudiarabica and Aloe shadensis methanolic extraction showed low cytotoxicity on the viability of A-549, MCF-7 and HepG2 cell lines.

Four selected commercial seaweeds: biologically active compounds, antioxidant and cytotoxic properties

The aim of this research work was to study the chemical characterisation, antioxidant and cytotoxic activity of ethanolic extracts of four commercial algae species Arame, Kombu, Hijiki and Wakame. The highest scavenging activity has been observed in Arame extract. Antioxidant potential of all extracts was in correlation with total phenol content (Arame extract: 319.15 ± 0.56 mg GAE/g d.w) and it was not in correlation with total carotenoids content (Wakame: 75.15 ± 0.20 mg/g). Polyphenols were quantified using LC-MS/MS technique. Baicalein and amentoflavone were identified in higher amount in relation to other phenols. Intracellular antioxidant activity and cytotoxicity of algae extracts were evaluated on the human prostate cancer cell line PC3. Although presented biomolecules in the extracts have demonstrated in vitro antioxidant activity, they did not show a significant effect on PC3 cells. However, this study opens up broad perspective for the further comprehensive investigation of these, commercial, seaweed’s biopotential.
