Medicinal plants become very important in our days for their therapeutic benefits to humankind. It sustains human health, and it is commonly known as herbal medicines since ancient times. Annona muricata is a heart-shaped fruit that is consumed raw or as the fruit juice in the tropical area. A. muricata is used in traditional and alternative medicine to treat different ailments such as diabetes, hypertension, respiratory and skin illness, inflammation and cancer. A. muricata contains essential anticancer agents named acetogenins that play the significant role in various cancer types. Acetogenins are strong nicotinamide adenine dinucleotide oxidase inhibitors of the cancer cell's mitochondrial membrane but showed neurotoxic effects in rats. Therefore, acetogenins need to be further investigated to determine the exact mechanisms of action, long-term safety, optimal dosage, and potential side effects. Given the extensive studies on A. muricata, this review focuses on the phytochemistry, medicinal uses, biological activities and the mechanisms of action for the fruit extracts and acetogenins, to stimulate further studies on the fruit pulp used for human consumption.
Evaluation of metabolomics behavior of human colon cancer HT29 cell lines treated with ionic liquid graviola fruit pulp extract

ETHNOPHARMACOLOGICAL RELEVANCE: Medicinal plants have been used by indigenous people across the world for centuries to help individuals preserve their wellbeing and cure diseases. Annona muricata L. (Graviola) which is belonging to the Annonaceae family has been traditionally used due to its medicinal abilities including antimicrobial, anti-inflammatory, antioxidant and cancer cell growth inhibition. Graviola is claimed to be a potential antitumor due to its selective cytotoxicity against several cancer cell lines. However, the metabolic mechanism information underlying the anticancer activity remains limited.
AIM OF THE STUDY: This study aimed to investigate the effect of ionic liquid-Graviola fruit pulp extract (IL-GPE) on the metabolomics behavior of colon cancer (HT29) by using an untargeted GC-TOFMS-based metabolic profiling.
MATERIALS AND METHODS: Multivariate data analysis was used to determine the metabolic profiling, and the ingenuity pathway analysis (IPA) was used to predict the altered canonical pathways after treating the HT29 cells with crude IL-GPE and Taxol (positive control).
RESULTS: The principal components analysis (PCA) identified 44 metabolites with the most reliable factor loading, and the cluster analysis (CA) separated three groups of metabolites: metabolites specific to the non-treated HT29 cells, metabolites specific to the treated HT29 cells with the crude IL-GPE and metabolites specific to Taxol treatment. Pathway analysis of metabolomic profiles revealed an alteration of many metabolic pathways, including amino acid metabolism, aerobic glycolysis, urea cycle and ketone bodies metabolism that contribute to energy metabolism and cancer cell proliferation.
CONCLUSION: The crude IL-GPE can be one of the promising anticancer agents due to its selective inhibition of energy metabolism and cancer cell proliferation.

Leukemia is a leukocyte cancer that is characterized by anarchic growth of immature immune cells in the bone marrow, blood and spleen. There are many forms of leukemia, and the best course of therapy and the chance of a patient's survival depend on the type of leukemic disease. Different forms of drugs have been used to treat leukemia. Due to the adverse effects associated with such therapies and drug resistance, the search for safer and more effective drugs remains one of the most challenging areas of research. Thus, new therapeutic approaches are important to improving outcomes. Almost half of the drugs utilized nowadays in treating cancer are from natural products and their derivatives. Medicinal plants have proven to be an effective natural source of anti-leukemic drugs. The cytotoxicity and the mechanisms underlying the toxicity of these plants to leukemic cells and their isolated compounds were investigated. Effort has been made throughout this comprehensive review to highlight the recent developments and milestones achieved in leukemia therapies using plant-derived compounds and the crude extracts from various medicinal plants. Furthermore, the mechanisms of action of these plants are discussed.
Antiproliferative activity of ionic liquid-graviola fruit extract against human breast cancer (MCF-7) cell lines using flow cytometry techniques

Daddiouaissa D, Amid A, Kabbashi NA, Fuad FAA, Elnour AM, Epandy MAKMS

J Ethnopharmacol, 2019 May 23;236:466-473.

ETHNOPHARMACOLOGICAL RELEVANCE: Medicinal plants have been used for ages by indigenous communities around the world to help humankind sustain its health. Graviola (Annona muricata), also called soursop, is a member of the Annonaceae family and is an evergreen plant that is generally distributed in tropical and subtropical areas of the world. Graviola tree has a long history of traditional use due to its therapeutic potential including anti-inflammatory, antimicrobial, antioxidant, insecticide and cytotoxic to tumor cells.
AIM OF THE STUDY: This study aimed to investigate the in vitro antiproliferative effects and apoptotic events of the ionic liquid extract of Graviola fruit (IL-GFE) on MCF-7 breast cancer cells and their cytokinetics behaviour to observe their potential as a therapeutic alternative in cancer treatment.
MATERIALS AND METHODS: The cell viability assay of the extract was measured using tetrazolium bromide (MTT assay) to observe the effects of Graviola fruit extract. Then the cytokinetics behaviour of MCF-7 cells treated with IL-GFE is observed by plotting the growth curve of the cells. Additionally, the cell cycle distribution and apoptosis mechanism of IL-GFE action on MCF-7 cancer cells were observed by flow cytometry.
RESULTS: IL-GFE exhibited anti-proliferative activity on MCF-7 with the IC50 value of 4.75 μg/mL, compared to Taxol with an IC50 value of 0.99 μg/mL. IL- GFE also reduced the number of cell generations from 3.71 to 1.67 generations compared to 2.18 generations when treated with Taxol. Furthermore, the anti-proliferative activities were verified when the growth rate was decreased dynamically from 0.0077 h to 1 to 0.0035 h-1. Observation of the IL-GFE-treated MCF-7 under microscope demonstrated detachment of cells and loss of density. The growth inhibition of the cells by extracts was associated with cell cycle arrest at the G0/G1 phase, and phosphatidylserine externalisation confirms the anti-proliferation through apoptosis.
CONCLUSIONS: ionic liquid Graviola fruit extract affect the cytokinetics behaviour of MCF-7 cells by reducing cell viability, induce apoptosis and cell cycle arrest at the G0/G1 phase.
