Background: Cancer is a major cause of mortality worldwide with increasing numbers by the years. In North Africa, the number of cancer patients is alarming. Also shocking is that a huge number of cancer patients only have access to traditional medicines due to several factors, e.g., economic difficulties. In fact, medicinal plants are widely used for the treatment of several pathologies, including cancer. Truthfully, herbalists and botanists in North African countries prescribe several plants for cancer treatment. Despite the popularity and the potential of medicinal plants for the treatment of cancer, scientific evidence on their anticancer effects are still scarce for most of the described plants.Objective: Bearing in mind the lack of comprehensive and systematic studies, the aim of this review is to give an overview of studies, namely ethnobotanical surveys and experimental evidence of anticancer effects regarding medicinal plants used in North Africa for cancer therapy.Method: The research was conducted on several popular search engines including PubMed, Science Direct, Scopus and Web of Science. The research focused primarily on English written papers published between the years 2000 and 2016.Results: This review on plants traditionally used by herbalists in North Africa highlights that Morocco and Algeria are the countries with most surveys on the use of medicinal plants in folk medicine. Among the plethora of plants used, Nigella sativa and Trigonella foenum-graecum are the most referred ones by herbalists for the treatment of cancer. Moreover, a plethora of scientific evidence qualifies them as candidates for further drug development. Furthermore, we report on the underlying cellular and molecular mechanisms.Conclusion: Overall, this review highlights the therapeutic potential of some medicinal plants as anticancer agents. The North African flora offers a rich source of medicinal plants for a wide array of diseases, including cancer. The elucidation of their modes of action represents an indispensable condition for the rational development of new drugs for cancer treatment. Furthermore, testing the anticancer activity in vivo and in clinical trials are warranted to explore the full therapeutic potential of North African plants for cancer therapy.

“…Among these medicinal plants, garlic ( Allium sativum L.) has secured its repute of a therapeutic panacea (Ankri and Mirelman, 1999). Garlic has been documented to possess antimicrobial (Feldberg et al, 1988; Ankri and Mirelman, 1999; Coppi et al, 2006; Ayazi, 2011; Wallock-Richards et al, 2014), anticancer (Thomson and Ali, 2003; Rana et al, 2011; Lee et al, 2013), antidiabetic (Lee et al, 2009), antiviral potential (Corzo-Martínez et al, 2007) and nevertheless, has ability to cope with cardiac complications (Lawson et al, 1992; Borek, 2001). Various organosulfur compounds such as DADS, DATS, DAS, Ajoene etc., have been suggested to contribute to the biological properties of garlic (Martins et al, 2016).…”

Garlic, from Remedy to Stimulant: Evaluation of Antifungal Potential Reveals Diversity in Phytoalexin Allicin Content among Garlic Cultivars; Allicin Containing Aqueous Garlic Extracts Trigger Antioxidants in Cucumber

et al. 2016

Garlic has the charisma of a potent remedy and holds its repute of a therapeutic panacea since the dawn of civilization. An integrated approach was adopted to evaluate the genetic diversity among Chinese garlic cultivars for their antifungal potency as well as allicin content distribution and, furthermore; a bioassay was performed to study the bio-stimulation mechanism of aqueous garlic extracts (AGE) in the growth and physiology of cucumber (Cucumis sativus). Initially, 28 garlic cultivars were evaluated against four kinds of phytopathogenic fungi; Fusarium oxysporum, Botrytis cinerea, Verticillium dahliae and Phytophthora capsici, respectively. A capricious antifungal potential among the selected garlic cultivars was observed. HPLC fingerprinting and quantification confirmed diversity in allicin abundance among the selected cultivars. Cultivar G025, G064, and G074 had the highest allicin content of 3.98, 3.7, and 3.66 mg g-1, respectively, whereas G110 was found to have lowest allicin content of 0.66 mg g-1. Cluster analysis revealed three groups on the basis of antifungal activity and allicin content among the garlic cultivars. Cultivar G025, G2011-4, and G110 were further evaluated to authenticate the findings through different solvents and shelf life duration and G025 had the strongest antifungal activity in all conditions. minimum inhibitory concentration and minimum fungicidal concentration of Allicin aqueous standard (AAS) and AGE showed significant role of allicin as primary antifungal substance of AGE. Leaf disk bioassay against P. capsici and V. dahliae to comparatively study direct action of AGE and AAS during infection process employing eggplant and pepper leaves showed a significant reduction in infection percentage. To study the bioactivity of AGE, a bioassay was performed using cucumber seedlings and results revealed that AGE is biologically active inside cucumber seedlings and alters the defense mechanism of the plant probably activating reactive oxygen species at mild concentrations. However, at higher concentrations, it might cause lipid peroxidation and membrane damage which temper the growth of cucumber seedlings. At the outcome of the study, an argument is advanced that current research findings provide bases for cultivar selection in antifungal effectivity as well as genetic variability of the cultivars. Allicin containing AGE can be used in specialized horticultural situations such as plastic tunnel and organic farming as a bio-stimulant to enhance cucumber growth and attenuate fungal degradation of agricultural produce.

Abstract. The present study was designed to investigate the antiproliferative activity of isoimperatorin against SGC-7901 cells and to examine the possible mechanisms. The antiproliferative activity of isoimperatorin against SGC-7901 cells was evaluated using an MTT assay, and the mechanisms were investigated using flow cytometry and western blot assays, which were used to determine the apoptotic rate and expression levels of mitochondria-mediated apoptosis-associated proteins, including Survivin, myeloid leukemia cell-1 (Mcl-1), B cell lymphoma-extra large (Bcl-xl), B cell lymphoma 2 (Bcl-2), second mitochondria-derived activator of caspase (Smac), Bcl-2-associated X factor (Bax), cleaved (c)-caspase-3 and c-caspase-9 in SGC-7901 cells. Additionally, a xenograft assay was used to confirm whether isoimperatorin had an inhibitory effect on SGC-7901 cell-induced tumors in vivo. The results of the MTT assay suggested that isoimperatorin significantly inhibited the proliferation of SGC-7901 cells in a dose-and time-dependent manner, and the half maximal inhibitory concentration was 18.75 µg/ml. The results of the flow cytometric analysis indicated that, following treatment with isoimperatorin, the apoptotic rate of SGC-7901 cells was significantly increased, compared with that of cells in the control group. The results of the western blot analysis indicated that, following treatment with isoimperatorin, the expression levels of the pro-apoptotic proteins, Bax, c-caspase-3 and c-caspase-9, were significantly increased and the expression levels of the anti-apoptotic proteins, Survivin and Bcl-2, were significantly reduced, compared with the control group. No alterations in expression were found in the other apoptosis-associated proteins, including Mcl-1, Bcl-xl and Smac. The results of the xenograft assay indicated that isoimperatorin significantly inhibited the growth of SGC-7901 cell-induced tumor in vivo by increasing the expression levels of pro-apoptotic proteins (Bax, c-caspase-3 and c-caspase-9) and reducing the expression levels of anti-apoptotic proteins (Survivin and Bcl-2) without adverse effects on the increasing body weight of nude mice. In conclusion, the present study revealed that isoimperatorin may be able to induce the apoptosis of SGC-7901 cells in vitro and in vivo by regulating the expression levels of mitochondria-mediated apoptosis-associated proteins.
