In this study we investigated the anti-cancer effect of Moringa oleifera leaves, bark and seed extracts. When tested against MDA-MB-231 and HCT-8 cancer cell lines, the extracts of leaves and bark showed remarkable anti-cancer properties while surprisingly, seed extracts exhibited hardly any such properties. Cell survival was significantly low in both cells lines when treated with leaves and bark extracts. Furthermore, a striking reduction (about 70–90%) in colony formation as well as cell motility was observed upon treatment with leaves and bark. Additionally, apoptosis assay performed on these treated breast and colorectal cancer lines showed a remarkable increase in the number of apoptotic cells; with a 7 fold increase in MD-MB-231 to an increase of several fold in colorectal cancer cell lines. However, no significant apoptotic cells were detected upon seeds extract treatment. Moreover, the cell cycle distribution showed a G2/M enrichment (about 2–3 fold) indicating that these extracts effectively arrest the cell progression at the G2/M phase. The GC-MS analyses of these extracts revealed numerous known anti-cancer compounds, namely eugenol, isopropyl isothiocynate, D-allose, and hexadeconoic acid ethyl ester, all of which possess long chain hydrocarbons, sugar moiety and an aromatic ring. This suggests that the anti-cancer properties of Moringa oleifera could be attributed to the bioactive compounds present in the extracts from this plant. This is a novel study because no report has yet been cited on the effectiveness of Moringa extracts obtained in the locally grown environment as an anti-cancer agent against breast and colorectal cancers. Our study is the first of its kind to evaluate the anti-malignant properties of Moringa not only in leaves but also in bark. These findings suggest that both the leaf and bark extracts of Moringa collected from the Saudi Arabian region possess anti-cancer activity that can be used to develop new drugs for treatment of breast and colorectal cancers.
N. sativa ( N. sativa ) has been used since ancient times, when a scientific concept about the use of medicinal plants for the treatment of human illnesses and alleviation of their sufferings was yet to be developed. It has a strong religious significance as it is mentioned in the religious books of Islam and Christianity. In addition to its historical and religious significance, it is also mentioned in ancient medicine. It is widely used in traditional systems of medicine for a number of diseases including asthma, fever, bronchitis, cough, chest congestion, dizziness, paralysis, chronic headache, back pain and inflammation. The importance of this plant led the scientific community to carry out extensive phytochemical and biological investigations on N. sativa . Pharmacological studies on N. sativa have confirmed its antidiabetic, antitussive, anticancer, antioxidant, hepatoprotective, neuro-protective, gastroprotective, immunomodulator, analgesic, antimicrobial, anti-inflammatory, spasmolytic, and bronchodilator activity. The present review is an effort to explore the reported chemical composition and pharmacological activity of this plant. It will help as a reference for scientists, researchers, and other health professionals who are working with this plant and who need up to date knowledge about it.
Liver disease is one of the major causes of morbidity and mortality across the world. According to WHO estimates, about 500 million people are living with chronic hepatitis infections resulting in the death of over one million people annually. Medicinal plants serve as a vital source of potentially useful new compounds for the development of effective therapy to combat liver problems. Moreover herbal products have the advantage of better affordability and acceptability, better compatibility with the human body, and minimal side effects and is easier to store. In this review attempt has been made to summarize the scientific data published on hepatoprotective plants used in Saudi Arabian traditional medicine. The information includes medicinal uses of the plants, distribution in Saudi Arabia, ethnopharmacological profile, possible mechanism of action, chemical constituents, and toxicity data. Comprehensive scientific studies on safety and efficacy of these plants can revitalise the treatment of liver diseases.
Lepidium sativum seed (LSS) (family: Cruciferae) has been used in traditional medicine for the treatment of jaundice, liver problems, spleen diseases and gastrointestinal disorders. It was also reported to possess antihypertensive, diuretic, anti-asthmatic, antioxidant, and anti-inflammatory activities. Attempt has been made to study hepatoprotective potential of LSS available in Saudi Arabian Market. The aim of the present study was to determine the hepatoprotective effect of ethanolic extracts of LSS against carbon tetrachloride (CCl4) induced acute liver injury in rats. The bioactive compounds responsible for this activity have been analyzed by GCMS.To evaluate the hepatoprotective activity, six groups (n = 6) of rats were taken. First group was control, second was toxic and other groups received oral test solutions: 100 mg/kg silymarin, or LSS (100, 200, and 400 mg/kg), once daily for 7 consecutive days, followed by hepatotoxicity induction with CCl4. Blood and liver tissues were collected for biochemical, antioxidant and microscopic analyses. The bioactive constituents present in the extract were analyzed by GCMS. Results showed that pretreatment with LSS and silymarin significantly reduced the level of serum alanine transaminase (ALT), aspartate transaminase (AST), alkaline phosphatase (ALP) and bilirubin (BIL), which was increased significantly in toxic group treated with only CCl4. Histological analysis of liver tissues in groups pretreated with LSS and silymarin showed mild necrosis and inflammation of the hepatocytes compared to the toxic group. GCMS analysis of LSS showed the presence of twelve major fatty acids including alpha-linolenic acid as a major constituent. These results indicated that LSS exerts enhance hepatoprotective activity that could be attributed towards its antioxidant activity, coupled together with the presence of anti-inflammatory compounds in LSS extract.
Diabetes and cancer are among the most frequent and complex diseases. Epidemiological evidence showed that the patients suffering from diabetes are significantly at higher risk for a number of cancer types. There are a number of evidence that support the hypothesis that these diseases are interlinked, and obesity may aggravate the risk(s) of type 2 diabetes and cancer. Multi-level unwanted alterations such as (epi-)genetic alterations, changes at the transcriptional level, and altered signaling pathways (receptor, cytoplasmic, and nuclear level) are the major source which promotes a number of complex diseases and such heterogeneous level of complexities are considered as the major barrier in the development of therapeutic agents. With so many known challenges, it is critical to understand the relationships and the commonly shared causes between type 2 diabetes and cancer, which is difficult to unravel and understand. Furthermore, the real complexity arises from contended corroborations that specific drug(s) (individually or in combination) during the treatment of type 2 diabetes may increase or decrease the cancer risk or affect cancer prognosis. In this review article, we have presented the recent and most updated evidence from the studies where the origin, biological background, the correlation between them have been presented or proved. Furthermore, we have summarized the methodological challenges and tasks that are frequently encountered. We have also outlined the physiological links between type 2 diabetes and cancers. Finally, we have presented and summarized the outline of the hallmarks for both these diseases, diabetes and cancer.
Objective: To evaluate the antimicrobial properties of Thymus vulgaris against seven pathogenic fungi strains and its cytotoxic effect on a human breast cancer cell line (MDA-MB-231) Methods: The susceptibility test was carried out in terms of by determining minimal inhibitory concentration (MIC) and minimum fungicidal concentration (MFC) using micro-dilution methods and additional end point by using MTS chromogenic assay. Cytotoxicity activity was assessed using MTT assay, the viability and the IC50 were used to evaluate this test. Results: All tested fungal strains were sensitive to the (Thymus vulgaris essential oil) TEO and this inhibitory effect is dose-dependent. A remarkable (p<0.001) inhibitory effect at concentrations 2.5-10mg/ml for all tested organisms comparable with control was found. The MIC 50 values ranged between 0.5 to 5mg/ml. The MFC values varied from 2.5-10 mg/mL and were equal to MIC values for majority of the tested organisms. As far as the antifungal activity is concern, out of the seven strains tested, Candida kefyr exhibited the highest sensitivity with minimal inhibition growth 2.5mg/ml whereas, Aspergillus niger exhibited the lowest inhibition ≥10mg/ml. Thymus vulgaris oil inhibited proliferation of MDA-MD-231 cancer cells in a time-and dose dependent manner. IC 50 value of the complex was found to be time dependent. At 24h treatment, the IC 50 values ranging between 108-115μg/ml, while at 48h treatment the values were between 71-78μg/ml against cancer cell. Conclusion: Thymus vulgaris essential oil exhibited significant antifungal and cytotoxic effects on living cells. Therefore, it can be used as alternative antifungal natural substances and also play a significant role in discovery of the new drugs.
Recently, there is a greater global interest in non synthetic, natural medicines derived from plant sources due to better tolerance and minimum adverse drug reactions as compared to synthetic medicines. Herbal products are also commonly used by the patients with certain chronic medical conditions, including breast cancer, liver disease, human immunodeficiency, asthma and rheumatological disorders. WHO estimates that about three-quarters of the world's population currently uses herbs and other forms of traditional medicines for the treatment of various diseases. The herbs are formulated in different modern dosage forms, such as Tablets, Capsules, Topical cream, Gel, Ointment and even some novel drug delivery forms, like extended release, sustained release, and microencapsules dosage forms. Patenting of herbal formulations has increased over the past few years and scientific evidence of therapeutic activity has been reported by performing various in vitro and in vivo experiments. This manuscript deals with various patented herbal formulations with their therapeutic application against various diseases.
