There are numerous herbal products on the Ghanaian market that are purported to cure various ailments, including cancer. However, scientific investigations on efficacy and toxicity of most of these products are not done. The aim of the study was to assess the anticancer potentials of herbal products on the Ghanaian market. Antiproliferative effects of Kantinka BA (K-BA), Kantinka Herbaltics (K-HER), Centre of Awareness (COA), a stomach (STO) and multicancer (MUT) product were evaluated in vitro using liver (Hep G2), breast (MCF-7), prostate (PC-3 and LNCaP), and blood (Jurkat) cancer cell lines. Cytotoxicity of the medicinal products was assessed using tetrazolium-based colorimetric assay, and total phenolic content and antioxidant activity of the products were determined using Folin-Ciocalteau and 1,1-diphenyl-2-picrylhydrazyl (DPPH) assays, respectively. Phytochemical screening resulted in the detection of terpenoids and flavonoids in most of the products, and alkaloids were detected in only MUT. Tannins were absent from all the products. The highest and lowest concentrations of phenolics were recorded for MUT and K-BA, respectively. The highest and lowest antioxidant activities were measured for MUT and K-HER, respectively. Only 2 products (STO and MUT) were cytotoxic to Hep G2 cells; with MUT being the only product that was cytotoxic to MCF-7 cells. All but K-BA were cytotoxic to PC-3 cells, while all products except K-HER were cytotoxic to LNCaP and Jurkat cells. The study thus confirms that the herbal products have selective cytotoxic activities against the tested cancer cell lines. However, comprehensive toxicity studies must be conducted to establish their safety.

A novel metabolite containing sulfur, fusaodavinvin (1), was isolated from an endophytic fungus Fusarium sp.(CTGU-ZL-34), together with seven known compounds 2-8, and their structures were elucidated by NMR spectroscopy and MS. This is the first record of 3-(2R-hydroxyl-1-one-propane)-indole (compound 2) from nature. The isolated compounds were evaluated using the A549, Hep G2, Caski and MCF-7 cell lines by the MTT method, and compound 1 displayed significant inhibiting activity of four cancer cell lines with IC50 values of 11.5, 15.3, 15.2 and 60.5 μg/mL, respectively. However, compound 2 displayed no significant anticancer activity to the above four cancer cell lines.

This paper reports the cytotoxic effect on several cancer cell lines of the stem extracts and of some isolated compounds from Ehretia asperula. All the extracts exhibited cytotoxic effects on at least one cancer cell line. The n-hexane extract showed potent cytotoxic activity on Hep-G2, MCF-7 and HeLa cell lines with IC50 values of 28.3 g/ml, 14.42 g/ml and 18.59 g/ml, respectively, while the methanolic, ethyl acetate and water extracts exhibited toxicity towards MCF-7 cells with IC50 values of 16.45 g/ml, 13.4 g/ml and 39.78 g/ml, respectively. 06 compounds have been isolated from the ethyl acetate fraction of Ehretia asperula stem. Methyl caffeate has a strong cytotoxicity against Hep-G2, HeLa and MCF-7 cancer cell lines with IC50 values of 2.83 g/ml, 3.38 g/ml and 4.4 g/ml, respectively. Oresbiusin B was active against Hep-G2 with IC50 value of 9.89 g/ml. The other compounds including coniferaldehyde, 9′-methoxydehydrodiconiferyl alcohol and vanillic acid did not have any cytotoxic effect on the tested cancer cell lines. So, the obtained results have suggested possibility of using the potential Ehretia asperula extracts as health food for preventing and curing cancer diseases.

AbstractBackgroundClerodendrumis a genus of about 500 species belongs to the family Lamiaceae. Many species of this genus have been proved for the treatment of various diseases. This study was aimed to evaluate the cytotoxic effect of different solvents and their most active fractions ofClerodendrum thomsoniaeBalf.f. in different human cancer cell lines. Aerial parts of the plant were subjected to Soxhlet extraction. Phytochemical analysis was done by using standard tests. In vitro anti-cancer activity on MCF-7, Hep-G2, A549, HT-29, MOLT-4, Hela, and Vero cell lines were evaluated by MTT assay.ResultsPhytochemical analysis confirmed the presence of most of the phytoconstituents in ethyl acetate extracts and the same extracts were found to be more cytotoxic activity to cancer cell lines MCF-7,Hep-G2,A549,HT–29, MOLT-4, and Hela with IC50values 29.43 ± 1.44 μg/ml, 43.22 ± 1.02 μg/ml, 56.93 ± 1.41 μg/ml, 60.68 ± 1.05 μg/ml, 69.83 ± 1.33 μg/ml, and 40.02 ± 1.14 μg/ml respectively, while it had no cytotoxic effect on normal Vero cells IC50= 367.5 ± 1.03 μg/ml. Ethyl acetate extracts were selected for the fractionation and MCF-7 cell line was used repeat MTT assay and found that fraction F5 was the most active fraction with IC5017.33 ± 0.54 μg/ml.ConclusionThese findings have proved thatClerodendrum thomsoniaeBalf.f. have significant cytotoxicity especially for breast cancer cell lines. Further studies are required for the isolation of constituents and to explore the mechanism of action.

Background: Breast cancer is the most commonly diagnosed cancer and the second leading cause of cancer deaths among Canadian women. Cancer management through changes in lifestyle, such as increased intake of foods rich in dietary flavonoids, have been shown to decrease the risk associated with breast, liver, colorectal, and upper-digestive cancers in epidemiologic studies. Onions are high in flavonoid content and one of the most common vegetables. Additionally, onions are used in most Canadian cuisines.Methods: We investigated the effect of five prominent Ontario grown onion (Stanley, Ruby Ring, LaSalle, Fortress, and Safrane) extracts on two subtypes of breast cancer cell lines: a triple negative breast cancer line MDA-MB-231 and an ER+ breast cancer line MCF-7.Results: These onion extracts elicited strong anti-proliferative, anti-migratory, and cytotoxic activities on both the cancer cell lines. Flavonoids present in these onion extracts induced apoptosis, cell cycle arrest in the G2/M phase, and a reduction in mitochondrial membrane potential at dose-dependent concentrations. Onion extracts were more effective against MDA-MB-231 compared to the MCF-7 cell line. Conclusion: In this study, we investigated the extracts synthesized from Ontario-grown onion varieties in inducing anti-migratory, cytostatic, and cytotoxic activities in two sub-types of human breast cancer cell lines. Anti-tumor activity of these extracts depends upon the varietal and can be formulated into nutraceuticals and functional foods for the wellbeing of cancer patients. Overall, the results suggest that onion extracts are a good source of flavonoids with anti-cancerous properties.Keywords: onion extracts; flavonoids; anti-proliferative; breast cancer; cytotoxic activity

Background: Target-based approach to drug discovery currently attracts a great deal of interest from medicinal chemists in anticancer drug discovery and development. Histone deacetylase (HDAC) inhibitors represent an extensive class of targeted anti-cancer agents. Among the most explored structure moieties, hydroxybenzamides and hydroxypropenamides have been demonstrated to have potential HDAC inhibitory effects. Several compounds of these structural classes have been approved for clinical uses to treat different types of cancer, such as vorinostat and belinostat. Aims: This study aims at developing novel HDAC inhibitors bearing conjugated quinazolinone scaffolds with potential cytotoxicity against different cancer cell lines. Method: A series of novel N-hydroxyheptanamides incorporating conjugated 6-hydroxy-2 methylquinazolin-4(3H)- ones (15a-l) was designed, synthesized and evaluated for HDAC inhibitory potency as well as cytotoxicity against three human cancer cell lines, including HepG-2, MCF-7 and SKLu-1. Molecular simulations were finally performed to gain more insight into the structure-activity. relationships. Results: It was found that among novel conjugated quinazolinone-based hydroxamic acids synthesized, compounds 15a, 15c and 15f were the most potent, both in terms of HDAC inhibition and cytotoxicity. Especially, compound 15f displayed up to nearly 4-fold more potent than SAHA (vorinostat) in terms of cytotoxicity against MCF-7 cell line with IC50 value of 1.86 µM, and HDAC inhibition with IC50 value of 6.36 µM. Docking experiments on HDAC2 isozyme showed that these compounds bound to HDAC2 with binding affinities ranging from -10.08 to -14.93 kcal/mol compared to SAHA (-15.84 kcal/mol). It was also found in this research that most of the target compounds seemed to be more cytotoxic toward SKLu-1than MCF-7 and HepG-2. Conclusion: The resesrch results suggest that some hydroxamic acids could emerge for further evaluation and the results are well served as basics for further design of more potent HDAC inhibitors and antitumor agents.
