Some species of the Baccharis genus have been shown to possess important biomedical properties, including cytotoxic activity. In this study, we examined the cytotoxic effect of methanol extract from Baccharis obtusifolia (Asteraceae) in cancer cell lines of prostate (PC-3), colon (RKO), astrocytoma (D-384), and breast (MCF-7). The methanolic extract displayed the largest substantial cytotoxic effect in lines of colon cancer (RKO) and cerebral astrocytoma (D-384). Chromatographic purification of the B. obtusifolia methanolic extract led to the isolation and identification of 5,4′-dihydroxy-7-methoxyflavone (1) and 5-hydroxy-7,4′-dimethoxyflavone (2) compounds of the flavonoid type.

 Objective: Cancer is a molecularly heterogeneous diseaseand the leading cause of death worldwide. The methanol extract of Clerodendrum phlomidis leaf has been reported for cytotoxicity. Hence, the current investigation was planned to evaluate the cytotoxic activity of the chemical constituents isolated from the methanol extract of the C. phlomidis leaf against the Michigan cancer foundation-7 (MCF-7) breast cancer and adenocarcinomic human alveolar basal epithelial cells (A549) lung cancer cell lines by the apoptotic study.Methods: Cytotoxic activity of the chemical constituents of the methanol extract of the C. phlomidis leaf was evaluated by the 3-(4,5-dimethylthiazol- 2-yl)-5-diphenyltetrazolium bromide (MTT) assay against breast cancer (MCF-7) and lung cancer (A549) cell lines. The MCF-7 and A549 cell lines were tested at different concentrations to determine 50% of growth inhibition (inhibitory concentration [IC50]) by MTT assay. Apoptosis of nuclei was detected by 4’,6-diamidino-2-phenylindole staining assay.Results: In MCF-7 breast cancer cell line study, Compounds 6 and 9 exhibited good cytotoxic activity with an IC50 value of 83.80 and 75.16 μg/ml, respectively. In A549 lung cancer cell line, again Compounds 6 and 9 exhibited good cytotoxic activity with an IC50 value of 84.46 and 78.60 μg/ml, respectively. Percentage of apoptosis induced by the Compounds 6 and 9 in the MCF-7 cancer cells was found to be 74.50 and 85.48, respectively.Conclusion: The results of the current study prove that the Compounds 6 and 9 are potential agents for breast and lung cancer. In future research, these potential agents can further be evaluated by animal studies and their mechanism of action apart from the induction of apoptosis of the cancer cells can be determined.

PURPOSE: Blumea lacera (B. lacera) (Asteraceae) is a well-known Bangladeshi medicinal plant. This study aimed to identify and characterize constituents associated with the significant cytotoxic activity of this plant that we reported previously. Here, we describe the isolation and characterization of a new steroidal glycoalkaloid (SGA) 1, the evaluation of its cytotoxic activity, apoptotic potential, and effect on cell cycle in comparison to analogous steroidal glycoalkaloids (SGAs). METHODS: SGA 1 was isolated using C18 SPE and HPLC, and subsequently structurally characterized using 1D and 2D NMR, MS and other spectroscopic methods, along with a comparative inspection of the literature. Cytotoxic activity of 1 and seven SGA analogues and steroidal alkaloids (SAs), (β-solamarine, α-solanine, β-solamargine, α-solasonine, khasianine, solasodine, tomatidine HCl) were evaluated for their cytotoxicity against two healthy (NIH3T3 and VERO) and four human cancer (AGS, HT-29, MCF-7 and MDA-MB-231) cell lines using the MTT assay. Cytotoxic SGAs were further evaluated for apoptosis-inducing potential and cell cycle arresting ability against breast cancer cells (MCF-7) using the FITC Annexin V and propidium iodide (PI) assay. RESULTS: Bioactivity guided fractionation of the methanol extract of B. lacera led to isolation of compound 1: (25R)-3β-{O-β-D-glucopyranosyl-(1→4)-O-α-L-rhamnopyranosyl-(1→4)-[O-α-L-rhamnopyranosyl-(1→2)]-α-L-rhamnopyranosyl}-22αN-spirosol-5-ene. SGA 1 was the most cytotoxic compound against a number of human cancer cell lines with an IC50 of 2.62 µM against MCF-7 cells. It displayed the highest apoptotic potential (32% AV+/PI-) on MCF-7 cells compared to other cytotoxic SGA analogues and a slight, but significant cell cycle arresting effect. CONCLUSIONS: A new SGA 1 was isolated from B. lacera and its cytotoxic activity, as well as that of other SAGs, was evaluated. SAR investigations on SGA 1, in relation to SGA analogues, show that the number and nature of sugar moieties along with the linkages of the sugar to the aglycone are crucial for cytotoxic and apoptotic activity. This article is open to POST-PUBLICATION REVIEW.

Abstract Since cancer remains one of the most prevalent diseases today, there is an urgent need for the development of new agents. Triterpenoids may act in multiple pathways displaying antiproliferative, antiangiogenic, anti-inflammatory, and pro-apoptotic activities that place them as promising multifunctional agents in treating cancer. In this paper a series of betulonic acid and its N-methylpyperazinyl amide derivatives, especially holding C2-nicotinoylidene/furfurylidene/fluorobenzylidene fragments, have been synthesized and evaluated for their cytotoxic activity against the NCI-60 cancer cell line panel. N-Methylpiperazinyl amides of betulinic acid 11 and 4-pyridinoylidene-betulinic acid 9 as well as betulonic acid C2-4-pyridinoylidene- 14 or furfurylidene 16 derivatives were found to be the leading compounds with GI50 values of 0.49 μM for leukemia CCRF-CEM, 1.60 μM and 1.36 μM for colon cancer HCT-116 and 1.66 μM for melanoma LOX IMVI cell lines, respectively. The activity displayed for these compounds was higher than for the standard drug doxorubicin against colon cancer HCT-15 and ovarian cancer NCI/ADR-RES cell lines. Cell cycle analysis indicates that compound 11 promotes cytotoxic activity through the apoptosis induction both in conditionally normal (HEK293) and in cancer (A549, MCF-7) cells, whereas compound 14 exhibits both cytostatic and cytotoxic activity, dependently on cell line evaluated. In particular, in HEK293 cells the compound 14 induces mainly apoptotic cell death, while in A549 and MCF-7 cells cytostatic effect is dependent on cell cycle arrest in G2/M phase.Our results suggest that betulinic acid N-methylpyperazinyl amide 11 is the promising compound for the future drug development antitumor studies.

We aimed to assess the antitumor activity of Orobanche crenata methanolic extract and evaluate its cytotoxic effect on different cancer cell lines to develop an effective natural anticancer drug. Components of O. crenata methanolic extract were analyzed using gas chromatography–mass spectrometry. The extract’s antioxidant activity was assessed by 2,2-diphenyl-1-picrylhydrazyl and ferric reducing antioxidant power procedures and cytotoxicity of the extract was assessed by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) and lactate dehydrogenase assays. Caspase-3 activity was also estimated. O. crenata methanolic extract shows powerful antioxidant activity. The extract inhibited the propagation of human hepatocellular carcinoma (HepG2), human prostate cancer (PC3), human breast adenocarcinoma (MCF-7), and human colon carcinoma (HCT-116) in a dose-dependent manner. O. crenata–treated cells displayed obvious morphological structures distinctive of apoptosis. MTT assay exposed that the extract presented prevention of cell persistence in a dose-dependent means and revealed extremely cytotoxic activity against HepG2, PC3, MCF-7, and HCT-116 with 50% inhibitory concentration values 30.3, 111, 89.6, and 28.6 µg/mL, respectively, after 24 h of incubation. In addition, treatment of HCT-116 with various concentrations of the extract caused the release of lactate dehydrogenase and induction of caspase-3 activity in a dose-dependent way. In conclusion, our findings suggested that the O. crenata extract possesses potent antioxidant, cytotoxic activity, and anticancer properties which are possibly due to the principal bioactive phytochemical composites existing in this plant. These results can be used to develop new drugs for cancer treatment.

The aim of this study was to investigate the anticancer and antioxidant activities as well as the safety of the brown algae Dictyota dichotoma of the Western seacoast of Yemen. Cytotoxicity of methanol extract of D. dichotoma and several of its fractions, petroleum ether, chloroform, ethyl acetate, n-butanol, and aqueous extracts against seven different cancer cell lines was determined by crystal violet staining. The antioxidant activity was also assessed using the DPPH radical scavenging assay. Acute toxicity study was performed on rats at increasing doses of the methanol extract. Extracts of D. dichotoma exerted a significant dose-dependent cytotoxicity on the seven tumor cell lines but were generally more selective on MCF-7 and PC-3. Among all fractions, the chloroform fraction of the D. dichotoma displayed the highest cytotoxic activity and was most effective in MCF-7, PC3, and CACO cells (IC50 = 1.93 ± 0.25, 2.2 ± 0.18, and 2.71 ± 0.53 μg/mL, respectively). The petroleum ether fraction was also effective, particularly against MCF-7 and PC-3 (IC50 = 4.77 ± 0.51 and 3.93 ± 0.51 μg/mL, respectively) whereas the activity of the ethyl acetate fraction was more pronounced against HepG2 and CACO (IC50 = 5.06 ± 0.21 and 5.06 ± 0.23 μg/mL, respectively). Of all the extracts tested, the crude methanolic extract of the algae exhibited only a modest antioxidant potential (IC50 = 204.6 ± 8.3 μg/mL). Doses as high as 5000 mg/kg body weight of D. dichotoma methanolic extracts were safe and well tolerated by rats. The overall results showed that D. dichotoma exhibited a significant cytotoxic activity probably due to the occurrence of nonpolar cytotoxic compounds, which is independent of its antioxidant capability.

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

Sarcopoterium spinosum (L.) is a medicinal plant traditionally used for the treatment of various diseases including cancer in the Near- and Middle East. The fractions and constituents of the ethanol extract of S. spinosum were screened for in vitro cytotoxic activities on Jurkat (acute T-lymphoblastic leukemia), HeLa (cervical adenocarcinoma), MCF-7 (mammary gland adenocarcinoma), Caco-2 (human colorectal adenocarcinoma), and MDA-MB-231 (mammary gland adenocarcinoma) cell lines using the MTT (3-(dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide) assay. The ethanol extract was subsequently re-extracted with ethyl acetate and in its sub-fraction obtained by column chromatography three compounds (stachydrine, benzalkonium chloride and rutine) were the first time identified by nuclear magnetic resonance (NMR) analyses. The most active subfraction showed cytotoxic activity against HeLa, MCF-7, and Caco-2 cell lines. The three compounds mentioned, as standards of high-performance liquid chromatography (HPLC) quality, were studied individually and in combination. Cytotoxic activity observed might be due to the presence of benzalkonium chloride and rutin. Benzalkonium chloride showed the strongest growth suppression effect against HeLa cells (IC50 8.10−7 M) and MCF-7 cells (IC50 5.10−6 M). The mixture of stachydrine and benzalkonium chloride allowed a synergistic cytotoxic effect against all tested cancer and normal cells to be obtained. Anti-cancer activity of the plant extract of S. spinosum remains under-investigated, so this research describes how the three major compounds identified in the ethyl acetate extract can exert a significant dose dependent in vitro cytotoxicity.
