AbstractCotinus coggygria Scop. leaf aqueous ethanolic extract was examined for its in vitro antiproliferative and antioxidant activity. Antiproliferative effect was assessed on four human gynecological cancer cell lines: breast (MCF7, T47D), cervical (HeLa) and ovarian (A2780) and compared to the cell growth inhibitory effect on non-cancerous breast epithelial cell line MCF10A using MTT cell proliferation assay. Radical scavenging assay with DPPH was applied to evaluate antioxidant potential of the extract. The obtained results showed that the herb inhibited cell growth of all of the tested cancer cell lines and the highest was the cytostatic effect on A2780 cells with a half maximal inhibitory concentration (IC50) value of 30.8 μg/ml. For the other cell lines the IC50values were in the range of 55-122.7 μg/ml. Additionally, the extract exerted considerably weaker reduction in cell proliferation of the non-cancerous cell line MCF10A compared to cancer cells, which indicates for antiproliferative selectivity. C. coggygria extract showed high free radical scavenging activity with an IC50value of 11.2 μg/ml. The obtained data provide evidence for pharmacological potential of the tested extract and future more detailed studies concerning the molecular mechanisms of the anticancer effect of the herb are needed.

Antiproliferative Activities

Cacti fruits are known to possess antioxidant and antiproliferative activities among other health benefits. The following paper evaluated the antioxidant capacity and bioactivity of five clarified juices from different cacti fruits (Stenocereus spp., Opuntia spp. and M. geomettizans) on four cancer cell lines as well as one normal cell line. Their antioxidant compositions were measured by three different protocols. Their phenolic compositions were quantified through high performance liquid chromatography and the percentages of cell proliferation of fibroblasts as well as breast, prostate, colorectal, and liver cancer cell lines were evaluated though in vitro assays. The results were further processed by principal component analysis. The clarified juice from M. geomettizans fruit showed the highest concentration of total phenolic compounds and induced cell death in liver and colorectal cancer cells lines as well as fibroblasts. The clarified juice extracted from yellow Opuntia ficus-indica fruit displayed antioxidant activity as well as a selective cytotoxic effect on a liver cancer cell line with no toxic effect on fibroblasts. In conclusion, the work supplies evidence on the antioxidant and antiproliferative activities that cacti juices possess, presenting potential as cancer cell proliferation preventing agents.

Although seaweeds and seagrasses have been used for food and traditional medicine for centuries, merely a small amount of them is exploited and used. Positive biological activities of seaweed and seagrass products on humans, animals and plants have also been recorded for a long time. Vietnam is a tropical country with 3,260 km long coastline and about 350 species of seaweeds, including 60 widely used species. In this study, 57 seaweed and seagrass samples were extracted using CHCl3/MeOH solvent systems and their crude extracts were tested for selected biological actives, including antimicrobial, antioxidant activities and cytotoxicity. The results revealed that 13 out of 57 extracts (accounting for 24.07%) were cytotoxic to one of the two tested cancer cell lines (Hepatocellular carcinoma cell line Hep-G2 and human lung adenocarcinoma cell line LU-1), and 4 extracts (accounting for 7.4%) were cytotoxic to both cancer cell lines. In antimicrobial activity assay, 18 of all 57 extracts (accounting for 37.5%) were capable of inhibiting 1 to 2 test microorganisms and 16 extracts (accounting for 33.33%) inhibited at least 3 test microorganisms. There were solely 1 extract (accounting for 1.85%) of the 57 extracts performing antioxidant activity in DPPH (1,1-diphenyl-2-picrylhydrazyl) radical scavenging assay.

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

Long noncoding RNA (lncRNA) GASL1 was identified as a novel lncRNA, which plays an important role in the proliferation and apoptosis of cells. This study aimed to compare the expression of GASL1 mRNA in kidney cancer cells and normal cells and detect the biological role of GASL1 in kidney cancer cell line A498. Polymerase chain reaction (PCR) was performed to examine the expression of GASL1 mRNA in kidney cancer tissues, normal tissues, and the cell lines. GASL1 overexpression was achieved in kidney cancer cell lines A498 through transfection. MTT was used to detect the effects of GASL1 overexpression in A498 cells. GASL1 mRNA was significantly overexpressed in adjacent normal tissues compared with renal cell carcinoma. The expression of GASL1 is lower in kidney cancer cell lines than in normal kidney epithelium cell line HREpiC. Overexpression of GASL1 inhibits the proliferation of renal carcinoma cell lines. GASL1 mRNA was down-regulated in kidney cancer tissues and may play a role in kidney cancer cell proliferation.

Sonchus Oleraceus

This study was designed to evaluate the anticancer, effects of the ethanolic (EE), cold aqueous (CAE), and hot aqueous (HAE) extracts of Sonchus oleraceus on cancer cell lines (in vitro). In vitro study was performed on three cancer cell lines (murine mammary adenocarcinoma AMN-3 cell line, laryngeal carcinoma Hep-2 cell line) and rat embryogenic fibroblast (REF) as normal cell line. Periods of exposure of cell lines were measured at 24, 48, and 72-hr in a microtitration plate under complete sterile conditions. Different concentrations starting from (78.125 to 10000) μg/ml of two fold dilution for each extract were prepared and tested on each cell line, with three replicates for each concentration. The three extracts showed concentration and time dependence with growth inhibitory effects, and the highest effect was obtained from ethanolic extract at higher concentrations after 48 hr. of exposures on both AMN3 and Hep-2 cell lines, while the cytotoxic effect of both cold aqueous and hot aqueous extracts on AMN-3 and Hep-2 cell lines exhibited that the higher concentrations gave a significantly (P<0.05) and the higher inhibition growth rate of cells were increased at 24 hrs.Conclusion: These results suggest that the cytotoxic concentrations of Sonchus oleraceus extracts showed variation in values among cell lines according to cell types in vitro.

Background: In the last few decades, plants have been playing a vital role in treating cancer and infectious diseases. Natural products have been rediscovered as effective methods of drug production amid advances in combinatorial chemistry. Roots of Martynia annua are being used as a folklore remedy for the treatment of cancer and rheumatism successfully. Aims of the Study: In the present study, ethanolic, aqueous and hydro-ethanolic root extracts of Martynia annua were screened for in vitro cytotoxicity activity using different cell lines. Settings and Design: In the experiment, lung cancer cell lines (A549), leukemia cancer cell lines (K562), oral cancer cell lines (SCC-40), breast cancer cell lines (MCF-7) & cervix cancer cell lines (SiHa) were studied on the extracts. Materials and Methods: The method used was Sulforhodamine B (SRB) assay technique in which growth inhibition of 50% (GI50) was analyzed by comparing it with standard drug Adriamycin (ADR) (doxorubicin). Results: Aqueous & ethanolic extract of Martynia annua root had shown high anticancer activity with GI50 value 11.3µg/ml and 20.4µg/ml respectively on human leukemia cell line K-562 but for human breast cancer cell line MCF-7, human lung cancer cell line A-549, human squamous cell carcinoma SCC-40 and human cervical cancer cell line SiHa the extracts showed activity in more than 80µg/ml. Conclusion: The anticancer activity of aqueous extract of Martynia annua root was found superior than the ethanolic extract in Human Leukemia Cell Line K-562. The study indicates that the Martynia annua root extracts are most effective against the fast proliferative cells (Leukemic cells) and possibly a cell cycle arrest (needed to be proved as future perspective) is the mode of action of the extract. To study its effect on targeted cancers, specific in vivo scientific studies and clinical trials should be carried out by further researchers.

The discovery for effective combinations of anticancer drugs for treatment for breast cancer is the actual problem in the experimental chemotherapy. In this paper we conducted a study of antitumor effect of the combination of sunitinib and bortezomib against MDA-MB-231 and SKBR-3 breast cancer cell lines in vitro. We found that bortezomib in non-toxic concentrations can potentiate the antitumor activity of sunitinib. MDA-MB-231 cell line has showed great sensitivity to the combination of bortezomib and sunitinib in vitro. Bortezomib and sunitinib caused reduced expression of receptor tyrosine kinases VEGFR1, VEGFR2, PDGFRa, PDGFRß and c-Kit on HER2- and HER2+ breast cancer cell lines

Background: The importance of inhibiting the kinases of the DDR pathway for radiosensitizing cancer cells is well established. Cancer cells exploit these kinases for their survival, which leads to the development of resistance towards DNA damaging therapeutics. Objective: In this article, the focus is on targeting the key mediator of the DDR pathway, the ATM kinase. A new set of quinoline-3-carboxamides, as potential inhibitors of ATM, is reported. Methods: Quinoline-3-carboxamide derivatives were synthesized and cytotoxicity assay was performed to analyze the effect of molecules on different cancer cell lines like HCT116, MDA-MB-468, and MDA-MB-231. Results: Three of the synthesized compounds showed promising cytotoxicity towards a selected set of cancer cell lines. Western Blot analysis was also performed by pre-treating the cells with quercetin, a known ATM upregulator, by causing DNA double-strand breaks. SAR studies suggested the importance of the electron-donating nature of the R group for the molecule to be toxic. Finally, Western-Blot analysis confirmed the down-regulation of ATM in the cells. Additionally, the PTEN negative cell line, MDA-MB-468, was more sensitive towards the compounds in comparison with the PTEN positive cell line, MDA-MB-231. Cytotoxicity studies against 293T cells showed that the compounds were at least three times less toxic when compared with HCT116. Conclusion: In conclusion, these experiments will lay the groundwork for the evolution of potent and selective ATM inhibitors for the radio- and chemo-sensitization of cancer cells.

Background:: Prostate cancer is still one of the serious causes of mortality and morbidity in men. Despite recent advances in anticancer therapy, there is a still need of novel agents with more efficacy and specificity in the treatment of prostate cancer. Because of its function on angiogenesis and overexpression in the prostate cancer, methionine aminopeptidase-2 (MetAP-2) has been a potential target for novel drug design recently. Objective:: A novel series of Flurbiprofen derivatives N-(substituted)-2-(2-(2-fluoro-[1,1'- biphenyl]-4-il)propanoyl)hydrazinocarbothioamide (3a-c), 4-substituted-3-(1-(2-fluoro-[1,1'-biphenyl]- 4-yl)ethyl)-1H-1,2,4-triazole-5(4H)-thione (4a-d), 3-(substitutedthio)-4-(substituted-phenyl)- 5-(1-(2-fluoro-[1,1'-biphenyl]-4-yl)ethyl)-4H-1,2,4-triazole (5a-y) were synthesized. The purpose of the research was to evaluate these derivatives against MetAP-2 in vitro and in silico to obtain novel specific and effective anticancer agents against prostate cancer. Methods: The chemical structures and purities of the compounds were defined by spectral methods (1H-NMR, 13C-NMR, HR-MS and FT-IR) and elemental analysis. Anticancer activities of the compounds were evaluated in vitro by using MTS method against PC-3 and DU-143 (androgenindependent human prostate cancer cell lines) and LNCaP (androgen-sensitive human prostate adenocarcinoma) prostate cancer cell lines. Cisplatin was used as a positive sensitivity reference standard. Results:: Compounds 5b and 5u; 3c, 5b and 5y; 4d and 5o showed the most potent biological activity against PC3 cancer cell line (IC50= 27.1 μM, and 5.12 μM, respectively), DU-145 cancer cell line (IC50= 11.55 μM, 6.9 μM and 9.54 μM, respectively) and LNCaP cancer cell line (IC50= 11.45 μM and 26.91 μM, respectively). Some compounds were evaluated for their apoptotic caspases protein expression (EGFR/PI3K/AKT pathway) by Western blot analysis in androgen independent- PC3 cells. BAX, caspase 9, caspsase 3 and anti-apoptotic BcL-2 mRNA levels of some compounds were also investigated. In addition, molecular modeling studies of the compounds on MetAP-2 enzyme active site were evaluated in order to get insight into binding mode and energy. Conclusion:: A series of Flurbiprofen-thioether derivatives were synthesized. This study presented that some of the synthesized compounds have remarkable anticancer and apoptotic activities against prostate cancer cells. Also, molecular modeling studies exhibited that there is a correlation between molecular modeling and anticancer activity results.

Background: The Epidermal Growth Factor Receptor (known as EGFR) induces cell differentiation and proliferation upon activation through the binding of its ligands. Since EGFR is thought to be involved in the development of cancer, the identification of new target inhibitors is the most viable approach, which recently gained momentum as a potential anticancer therapy. Objective: To assess various pyrazole linked pyrazoline derivatives with carbothioamide for EGFR kinase inhibitory as well as anti-proliferative activity against human cancer cell lines viz. A549 (non-small cell lung tumor), MCF-7 (breast cancer cell line), SiHa (cancerous tissues of the cervix uteri), and HCT-116 (colon cancer cell line). Methods: In vitro EGFR kinase assay, in vitro MTT assay, Lactate dehydrogenase release, nuclear staining (DAPI), and flow cytometry cell analysis. Results: Compounds 6h and 6j inhibited EGFR kinase at concentrations of 1.66μM and 1.9μM, respectively. Furthermore, compounds 6h and 6j showed the most potent anti-proliferative results against the A549 KRAS mutation cell line (IC50 = 9.3 & 10.2μM). Through DAPI staining and phase contrast microscopy, it was established that compounds 6h and 6j also induced apoptotic activity in A549 cells. This activity was further confirmed by FACS using Annexin-V-FITC and Propidium Iodide (PI) labeling. Molecular docking studies performed on 6h and 6j suggested that the compounds can bind to the hinge region of ATP binding site of EGFR tyrosine kinase in a similar pose as that of the standard drug gefitinib. Conclusion: The potential anticancer activity of compounds 6h and 6j was confirmed and need further exploration in cancer cell lines of different tissue origin and signaling pathways, as well as in animal models of cancer development.
