clove and Lung-Neoplasms

Lung Cancer (LC) is an emergent disease widespread globally. Compared to other types of cancer, LC has one of the lowest survival rates (18%). As some risk factors associated with the development of lung carcinogenesis are still unavoidable, researchers have been trying to find efficient and safe alternatives that can help prevent LC or even attenuate its rapid evolution after diagnosis. Studies with natural products promise to offer biological effects against several types of cancers, including LC. The uncountable types of plant matrices dispersed in nature, or even their extracts, contain a powerful composition of bioactive compounds with promising biological effects on LC. The biomes in Brazil are examples of regions with a great biodiversity of bioactive compounds-rich fruits. Therefore, this review aimed to present the potential anticancer effect of Brazilian native fruits, their fractions, and by-products on LC through the elucidation of the main molecular mechanisms involved. The Brazilian plant matrices discussed here (açaí, achiote, araticum, camu camu, cocoa, jaboticaba, genipap, guarana, and pequi) showed promising evidence by inducing cellular apoptosis, reducing cancer cell viability and tumor growth, and regulating cell cycle.

Lemon myrtle (Backhousia citriodora F.Muell.) leaves, whether fresh or dried, are used traditionally in folk medicine to treat wounds, cancers, skin infections, and other infectious conditions. However, the targets and mechanisms related to anti-cancer effect of lemon myrtle are unavailable. In our study, we found that the essential oil of lemon myrtle (LMEO) showed anti-cancer activity in vitro, and we initially explored its mechanism of action.. We analyzed the chemical compositions of LMEO by GC-MS. We tested the cytotoxicity of LMEO on various cancer cell lines using the MTT assay. Network pharmacology was used also to analyze the targets of LMEO. Moreover, the mechanisms of LMEO were investigated through scratch assay, flow cytometry analysis, and western blot in the HepG2 liver cancer cell line.. LMEO showed cytotoxicity in various cancer cell lines in vitro. Pharmacological networks showed LMEO to have multi-component and multi-targeting effects that are related to inhibit migration of HepG2 cells, and affect cell cycle S-phase arrest and apoptosis through modulation of p53 protein.

Plants of the Myrcia genus have been widely used in folk medicine to treat various diseases, including cancer. Myrcia splendens species has a diverse chemical constitution, but the biological activities of its essential oil have not been well investigated. In this study to out the chemistry characterization of essential oil (EO) from the leaves of the species M. splendens from Brazil and evaluate cytotoxic effect in A549 lung cancer cells.. M. splendens EO was obtained by hydrodistillation and analyzed by Gas Chromatography-Mass Spectrometry (GC-MS). EO was isolated and evaluated for cellular viability in tumor cell lines by MTT assay. The evaluation of the formation of clones and the migratory capacity of the A549 cells treated with EO was done by the clonogenic assay and the wound healing assay. Morphological changes were observed in A549 cells by fluorescence using Phalloidin/FITC and DAPI.. The findings of this study suggest that the M. splendens EO has cytotoxic compounds for the A549 lung cancer cells. Treatment with the EO decreased the colony formation and reduced the ability of lung cancer cells to migrate. Future studies may be used to isolate compounds from the EO for the study of lung cancer.

The time between clinical symptoms onset and the diagnosis of bronchial cancer should be as short as possible so that it can be managed early and effectively. In Madagascar, this diagnostic delay is unknown. Therefore this study aims to evaluated the diagnostic delay of bronchopulmonary cancers at the the USFR Befelatanana Pneumology, Antananarivo, Madagascar. We conducted a retrospective descriptive study of patients with bronchopulmonary cancers diagnosed at the USFR Befelatanana Pneumology over the period 1

Baeckea frutescens is a natural remedy recorded to be used in curing various health conditions. In Peninsular Malaysia, B. frutescens is found on the mountain tops, quartz ridge and sandy coasts. To our knowledge, there is only limited published literature on B. frutescens.. B. frutescens leaf crude methanol and its fractionated extracts (hexane, ethyl acetate and water) were prepared. Folin-Ciocalteau's method was used for the measurement of total phenolic content of the extracts. The antioxidant activity was measured by the scavenging activity on DPPH (1,1-diphenyl-2-picrylhydrazyl) radicals, reducing power assay through the Prussian blue complex formation, the metal chelating assay as well as the β-Carotene-linoleic acid system assay. The cytotoxic activity of the extracts were evaluated against two lung carcinoma cell lines with varying molecular characteristics using the MTT [3-(4, 5-dimethylthiazol-2-yl)-2, 5-diphenyltetrazolium bromide] assay. Lastly the toxicity of the crude methanol extract was evaluated using the acute oral toxicity experiment.. The methanolic extract with highest phenolic content showed the strongest β-carotene bleaching inhibition, whilst the water extract exhibited the highest activity in metal chelating and reducing power assays. The hexane extract displayed a mild cytotoxic effect on both A549 and NCI-H1299 human lung carcinoma cell lines. No mortalities and no adverse effects were observed in the acute oral toxicity investigation at the highest dose of 5000 mg/kg.. The findings in the present study suggest B. frutescens may be considered as a safe source of compounds with antioxidant and cytotoxic properties for therapeutic and functional food applications.

Investigation of the endemic Madagascan plant Nematostylis anthophylla (Rubiaceae) for antiproliferative activity against the A2780 ovarian cancer cell line led to the isolation of the known triterpene saponin randianin (1), and the two new bioactive triterpene saponins 2"-O-acetylrandianin (2) and 6"-O-acetylrandianin (3). The structures of the two new compounds were elucidated based on analysis of their 1D- and 2D-NMR spectra, and mass spectrometric data. The three isolated triterpene saponins displayed moderate but selective antiproliferative activities, with IC(50) values of 1.2, 1.7, and 2.2 μM, respectively, against the A2780 ovarian cancer, but only weak inhibitions of the proliferation of A2058 melanoma and the H522 lung cancer cell lines.

Investigation of the Madagascan endemic plant Ambavia gerrardii for antiproliferative activity against the A2780 ovarian cancer cell line led to the isolation of the three new alkaloids 8-hydroxyeupolauridine (1), 9-methoxyeupolauridine 1-oxide (2), and 11-methoxysampangine (3) and the three known alkaloids 4-6. The structures of 1 and 2 were confirmed by synthesis. Compounds 3, 4, and 6 showed moderate to good antiproliferative activities, with IC50 values of 10.3, 3.5, and 0.60 μM, respectively, against the A2780 human ovarian cancer cell line and with IC50 values of 0.57, 1.77, and 0.58 μM, respectively, against the H460 human lung cancer cell line.

Bioassay-guided fractionation of a CH(2)Cl(2)/MeOH extract of the bark of Casearia lucida resulted in the isolation of 11 new clerodane diterpenes, namely, casearlucins A-K (1-11), and three known clerodane diterpenoids, rel-(2S,5R,6R,8S,9S,10R,18S,19R)-diacetoxy-18,19-epoxy-6-hydroxy-2-(2xi-methylbutanoyloxy)cleroda-3,13(16),14-triene (12), rel-(2S,5R,6R,8S,9S,10R,18S,19R)-18,19-diacetoxy-18,19-epoxy-6-methoxy-2-(2xi-methylbutanoyloxy)cleroda-3,13(16),14-triene (13), and rel-(2S,5R,8S,9S,10R,18S,19R)-18,19-diacetoxy-18,19-epoxy-2-(2xi-methylbutanoyloxy)cleroda-3,13(16),14-triene (14). The structures of compounds 1-11 were established on the basis of extensive 1D and 2D NMR spectroscopic data interpretation. All compounds exhibited cytotoxicity activity against the A2780 ovarian cancer cell line, but none of the six compounds selected for testing in multiple cell lines showed significant selectivity.
