Analyzing Cytotoxic and Apoptogenic Properties of Scutellaria litwinowii Root Extract on Cancer Cell Lines

The Scutellaria species (Lamiaceae) is used as a source of flavonoids to treat a variety of diseases in traditional medicine. In spite of many reports about the cytotoxic and antitumor effects of some species of this genus, anticancer researches on one of the Iranian species S. litwinowii have not yet been conducted. The cytotoxic properties of total methanol extract of S. litwinowii and its fractions were investigated on different cancer cell lines including AGS, HeLa, MCF-7, PC12 and NIH 3T3. Meanwhile, the role of apoptosis in this toxicity was explored. The cells were cultured in DMEM medium and incubated with different concentrations of herb plant extracts. Cell viability was quantitated by MTT assay. Apoptotic cells were determined using propidium iodide staining of DNA fragmentation by flow cytometry (sub-G1 peak). Scutellaria litwinowii inhibited the growth of malignant cells in a dose-dependent manner. Among solvent fractions of S. litwinowii, the methylene chloride fraction was found to be more toxic compared to other fractions. The IC50 values of this fraction against AGS, HeLa, MCF-7 and PC12 cell lines after 24 h were determined, 121.2 ± 3.1, 40.9 ± 2.5, 115.9 ± 3.5 and 64.5 ± 3.4 μg/ml, respectively. Scutellaria litwinowii induced a sub-G1 peak in the flow cytometry histogram of treated cells compared to control cells indicating that apoptotic cell death is involved in S. litwinowii toxicity. Scutellaria litwinowii exerts cytotoxic and proapototic effects in a variety of malignant cell lines and could be considered as a potential chemotherapeutic agent in cancer treatment

Cancer and Its Treatment in Main Ancient Books of Islamic Iranian Traditional Medicine (7th to 14th Century AD)

ABSTRACT: Islamic medicine is regarded as a comprehensive medical school with a long, glorious and worldwide reputation. Some of the physicians of this school are famous worldwide and have contributed valuable services to the scientific world. Given the dramatically increasing prevalence of cancer and the relative inefficacy of current medications, there is a great demand for the introduction of effective therapeutic approaches. To this end, integration of traditional medicine with modern medical treatments represents a promising option. In this essay, methods of diagnosis and treatment of cancer have been mentioned from the viewpoint of five famous physicians before the Mongolian attack who used Islamic medicine, namely Rhazes, Akhaveyni, Ahwazi, Avicenna and Jorjani. The ideas discussed dates back to a period between the eighth and fourteenth centuries

Ethnobotanical and phytochemical aspects of the edible herb Coriandrum sativum L.

Financiado para publicación en acceso aberto: Universidade de Vigo/CISUGCoriandrum sativum (coriander) is an edible herb in the family Apiaceae. The leaves, fruits, and stems of C. sativum have long been used as culinary spice due to their favorable odor. Traditional practitioners used this plant for treating different diseases like blepharitis, scabies, aphthous stomatitis, laryngitis, headache, and palpitation. In modern researches, coriander has demonstrated anxiolytic, anticonvulsant, antimigraine, neuroprotective, analgesic, diuretic, hypoglycemic, hypolipidemic, hypotensive, anticancer, and antioxidant activities. Coriander contains a wide range of bioactive phytochemicals among which phenylpropenes, terpenoids, isocoumarins, phytosterols, and fatty acids are the most important. This review provides information about the botanical and ethnobotanical aspects, chemical profile, therapeutic uses in Islamic traditional medicine (ITM), and recent pharmacological studies of coriander effects. The results have shown that coriander and its monoterpenoid compound, linalool, can be considered as potential drug candidates for treating metabolic syndrome and different inflammatory conditions especially neural and CNS diseases

A modern formulation of traditional medicine: Jujube) Ziziphus jujuba Mill.) fruit syrup

Ziziphus jujuba Mill.,commonly called jujube (Rhamnaceae) has been known for its health benefits and used to cure different diseases such as asthma, cough and anxiety. The aim of this study is a formulation of its syrup and evaluation of physicochemical properties in accelerated stability conditions. The isosbestic point of spinosin (as marker) and its stability kinetic was studied in different buffers (pH range: 3-8). The isosbestic point was 259 nm that was different from max (334 nm). It was found that spinosin was more stable at pH of 7. So, the pH of the syrup was adjusted to 7. The syrup was a brown viscous liquid with jujube fruit flavor. Dry residue, pH, density and viscosity of the syrup were found to be 0.8 g/mL, 7, 1.29 g/mL and 0.14 Pa/s, respectively. During accelerated stability studies no significant changes were observed in physical properties and 3.2% decrease in spinosin content was seen that is acceptable. The preservative effectiveness test showed that the free preservative formulation met the USP criteria. In conclusion, Z. jujuba fruit syrup has a suitable potential to be manufactured on the mass production for traditional herbal medicine markets

Phytochemicals as Modulators of Paraoxonase?1 in Health and Diseases

Chronic diseases such as cardiovascular disease (CVD), atherosclerosis, chronic liver disease, and neurodegenerative diseases are major causes of mortality. These diseases have gained much attention due to their complications, and therefore novel approaches with fewer side effects are an important research topic. Free radicals and oxidative stress are involved in the molecular mechanisms of several diseases. Antioxidants can scavenge free radicals and mitigate their adverse effects. One of the most important antioxidant enzymes are paraoxonases (PONs). These enzymes perform a wide range of physiological activities ranging from drug metabolism to detoxification of neuroleptics. Paraoxonase?1 (PON1) is produced in the liver and then transferred to the bloodstream. It has been demonstrated that PON1 could have beneficial effects in numerous diseases such as atherosclerosis, CVD, diabetes mellitus, and neurodegenerative diseases by modulating relevant signalling pathways involved in inflammation and oxidative stress. These pathways include peroxisome proliferator?activated receptor gamma (PPAR??) and protein kinase B/nuclear factor kappa?light?chain?enhancer of activated B cells (AKT/NF??B)?dependent signalling pathways. Increasing PON1 could potentially have protective effects and reduce the incidence of various diseases by modulating these signalling pathways. Several studies have reported that dietary factors are able to modulate PON1 expression and activity. This review aimed at summarizing the state of the art on the effects of dietary phytochemicals on PON1 enzyme activity and the relevant signalling pathways in different diseases

Evaluation of anti-oxidant and antimelanogenic effects of the essential oil and extracts of Rosa × damascena in B16F10 murine melanoma cell line

Objective(s): Rosa × damascena Herrm. belonging to the Rosaceae family has demonstrated anti-inflammatory and anti-oxidant effects previously. Excessive production of free radicals and activation of tyrosinase enzyme caused by UV induces excessive concentration of melanin pigment and skin spots in the long term. Therefore, finding natural sources with anti-oxidant and antityrosinase effects helps to regulate the melanogenesis process.  In the current research, we investigated the antimelanogenic, anti-oxidant, and anti-tyrosinase effects of its essential oil, methanol extract (MeOH), and different fractions including n-hexane, dichloromethane (CH2Cl2), n-butanol (BuOH), ethyl acetate (EtOAc), and H2O of R. × damascena in B16F10 cell line.Materials and Methods: For this purpose, impacts of extracts and essential oil of R. × damascena were investigated on cell viability, cellular tyrosinase, melanin content, mushroom tyrosinase, reactive oxygen species (ROS) production, as well as the amount of tyrosinase protein in the B16F10 murine melanoma cell line.Results: Essential oil, MeOH, and different fractions of R. × damascena were not cytotoxic on B16F10 cells. However, they had significant reducing effects on mushroom tyrosinase activity, melanin content, and ROS production. Also, there is a significant decrease in tyrosinase protein levels at 200 µg/ml but not at other concentrations. Conclusion: Therefore, the essential oil, MeOH, and different fractions of R. × damascena had promising antimelanogenic activity via repression of mushroom tyrosinase activity and ROS production
