O estudo do estresse oxidativo nos tecidos estomacais mostrou um aumento significativo dos níveis das enzimas antioxidantes superóxido dismutase, catalase e glutationa peroxidase, com uma diminuição significativa da peroxidação lipídica enquanto pré-tratamento com POE. Em conclusão, o POE protege contra úlcera gástrica devido aos seus potenciais antioxidantes e à presença de moléculas bioativas.

Phytochemical profile and biological activities of Bromelia antiacantha extracts / Perfil fitoquímico e atividades biológicas de extratos de Bromelia antiacantha

Reports from popular medicine usually act as a basis for the development of new drugs from natural compounds with therapeutic actions for serious diseases and prevalence such as cancer. Bromelia antiacantha Bertol. is a species of the Bromeliaceae family, considered an unconventional food plant, found in the south and midwest regions of Brazil. Despite the high nutritional content and pharmacological potential of its fruits, few scientific studies report its biological actions. Thus, this study evaluates the phytochemical profile of aqueous and ethanol extracts obtained from B. antiacantha fruits, as well as their possible antioxidant, antitumor, and cytotoxic activities. The aqueous extract exhibited phenolic compounds and flavonoids, while ethanol extracts indicated the presence of flavonoids and coumarin in their composition, regardless of the region of collection. The ethanolic extract demonstrated a more promising antioxidant effect than the aqueous extract and also induced a significant inhibition in the viability of human cervical cancer cells of the SiHa strain. In addition, treatment with both extracts did not alter the viability of non-tumor cells of the immortalized human keratinocyte lineage (HaCaT). These results bring new data about extracts obtained from a native plant, edible and traditionally used in popular medicine, opening new perspectives for its possible therapeutic application.

Relatos da medicina popular costumam atuar como referencial para o desenvolvimento de novos fármacos a partir de moléculas naturais com ações terapêuticas para doenças de alta gravidade e prevalência como o câncer. Bromelia antiacantha Bertol. é uma espécie da família Bromeliaceae, considerada uma planta alimentícia não convencional (PANC), encontrada nas regiões sul e centro-oeste do Brasil. Apesar do alto teor nutritivo e potencial farmacológico de seus frutos, poucos estudos científicos relatam suas ações biológicas. Desta forma, este estudo avalia o perfil fitoquímico de extratos aquoso e etanólico obtidos de frutos de B. antiacantha, bem como a sua possível ação antioxidante, antitumoral e citotóxica. O extrato aquoso apresentou compostos fenólicos e flavonoides, enquanto os extratos etanólicos apontam a presença de flavonóides e cumarina em sua composição, independente da região de coleta. O extrato etanólico demonstrou efeito antioxidante mais promissor do que o extrato aquoso e também induziu uma inibição significativa na viabilidade de células humanas de câncer cervical da linhagem SiHa. Além disso, o tratamento com ambos extratos não alterou a viabilidade de células não tumorais da linhagem de queratinócitos humanos imortalizados (HaCaT). Estes dados trazem novas informações sobre extratos obtidos de uma espécie vegetal nativa, comestível e já utilizada tradicionalmente, mas abrindo novas perspectivas quanto a possíveis aplicações terapêuticas.

Dipsacus and Scabiosa Species-The Source of Specialized Metabolites with High Biological Relevance: A Review.

The genera Dipsacus L. and Scabiosa L. of the Caprifoliaceae family are widely distributed in Europe, Asia, and Africa. This work reviews the available literature on the phytochemical profiles, ethnomedicinal uses, and biological activities of the most popular species. These plants are rich sources of many valuable specialized metabolites with beneficial medicinal properties, such as triterpenoid derivatives, iridoids, phenolic acids, and flavonoids. They are also sources of essential oils. The genus Dipsacus has been used for centuries in Chinese and Korean folk medicines to treat bone (osteoporosis) and joint problems (rheumatic arthritis). The Korean Herbal Pharmacopoeia and Chinese Pharmacopoeia include Dipsaci radix, the dried roots of D. asperoides C.Y.Cheng & T.M.Ai. In addition, S. comosa Fisch. ex Roem & Schult. and S. tschiliiensis Grunning are used in traditional Mongolian medicine to treat liver diseases. The current scientific literature data indicate that these plants and their constituents have various biological properties, including inter alia antiarthritic, anti-neurodegenerative, anti-inflammatory, antioxidant, anticancer, and antimicrobial activities; they have also been found to strengthen tendon and bone tissue and protect the liver, heart, and kidney. The essential oils possess antibacterial, antifungal, and insecticidal properties. This paper reviews the key biological values of Dipsacus and Scabiosa species, as identified by in vitro and in vivo studies, and presents their potential pharmacological applications.

The effect of infusion time on Echium amoenum extract -induced hepatotoxicity in vitro.

Echium amoenum is an annual herb native to the northern mountains of Iran which has medicinal application. Petals of Echium amoenum (Gole-Gavzaban) is one of the most valuable medicinal plants in Iranian folk medicine. The dry petals of E. amoenum have long been used as a sedative, tonic, anxiolytic and as a treatment for sore throat, cough and inflammation. Previous studies have shown that petals of E. amoenum contain four toxic pyrrolizidine alkaloids but conflicting results have been acquired in experimental studies investigating the hepatotoxicy of E. amoenum. However, the direct effect of E. amoenum on liver cells and the complete mechanisms of its possible cytotoxic effects toward these cells remain to be defined. The main aim of this study was to assay the mechanisms underlying the toxic effects of E. amoenum toward hepG2 cells. E. amoenum extract was obtained by infusion of dried petals in hot water (90 centigrade) for 15 or 30 min. Cell viability and mechanistic parameters were determined following 12 h incubation of hepG2 with E. amoenum extract that was obtained after 15 or 30 min infusion. The results indicated that E. amoenum extract exerts cytotoxic effects on hepG2 cells, probably through mitochondrial and lysosomal damage induced by glutathione depletion and oxidative stress.

The Genus Cuphea P. Browne as a Source of Biologically Active Phytochemicals for Pharmaceutical Application and Beyond-A Review.

Cuphea P. Browne (Lythraceae) is a monophyletic taxon comprising some 240-260 species that grow wild in the warm, temperate, and tropical regions of South and Central America and the southern part of North America. They have been valued as traditional medicinal remedies for numerous indications, including treating wounds, parasitic infections, hypertension, digestive disorders, cough, rheumatism, and pain. Modern pharmacological research provides data that support many of these traditional uses. Such a wide array of medicinal applications may be due to the exceptionally rich phytochemical profile of these plants, which includes bioactive compounds classified into various metabolite groups, such as polyphenols, triterpenes, alkaloids, and coumarins. Furthermore, Cuphea seed oils, containing medium-chain fatty acids, are of increasing interest in various industries as potential substitutes for coconut and palm oils. This review aims to summarize the results of phytochemical and pharmacological studies on Cuphea plants, with a particular focus on the therapeutic potential and molecular mechanisms of the action of polyphenolic compounds (especially flavonoids and tannins), which have been the subject of many recently published articles.

Recent insights into the hepatoprotective potential of medicinal plants and plant-derived compounds.

Liver problems are a worldwide concern, and conventional medicinal therapies are ineffective. Hence, safeguarding the healthy liver is vital for good health and well-being. Infections due to virus, immune problems, cancer, alcohol abuse, and an overdose of drugs are some of the causes of liver diseases. Antioxidants derived from medicinal plants and conventional dietary sources can protect the liver from damages caused by oxidative stress system and various chemicals. Plants and plant-derived phytochemicals are appealing hepatoprotective agents since they have less side effects and still there is a lot of interest shown in using herbal tonics for treating liver disorders. This review therefore primarily focuses on newly discovered medicinal plants and compounds produced from plants that fall under the classifications of flavonoids, alkaloids, terpenoids, polyphenolics, sterols, anthocyanins, and saponin glycosides, all of which have the potential to be hepatoprotective. Hosta plantaginea, Ligusticum chuanxiong, Daniella oliveri, Garcinia mangostana, Solanum melongena, Vaccinium myrtillus, Picrorhiza kurroa, and Citrus medica are some potential plants having hepatoprotective effects. We conclude that these phytochemicals and the plant extracts listed above are used in the future to treat a variety of liver diseases, additional research is still needed to develop safer and more potent phytochemical drugs.

A comprehensive review of antitumor properties of Angelica species and their antitumor-responsible constituents and the underlying molecular mechanisms involved in tumor inhibition.

Recent studies have suggested their potential use as anticancer agents, making them an area of interest for further research. The review aims to summarize the current understanding of the potential anticancer effects of Angelica species and to provide insights for further research in this area. We searched for "Angelica" related information on Google Scholar, PubMed, ScienceDirect, Wiley, Science Citation Index Finder, and Springer link by searching keywords such as "Angelica," "Angelica phytochemical," "Angelica antitumor effect," "Angelica molecular mechanisms," and "Angelica clinical application." Included articles focused on the Angelica plant's anticancer properties and clinical studies, while non-cancer-related biological or phytochemical investigations were excluded. We conducted a comprehensive search of books, journals, and databases published between 2001 and 2023, identifying 186 articles for this narrative review. The articles were analyzed for their potential anticancer properties and therapeutic applications. Active compounds in the Angelica genus, such as coumarins, furanocoumarins, phthalides, and polysaccharides, exhibit anticancer properties through various mechanisms. Specific species, like A. archangelica, Angelica sinensis, A. gigas, and A. ksiekie, have the potential as anticancer agents by targeting cellular pathways, generating reactive oxygen species, and inducing apoptotic cell death. Further research into the properties of the Angelica genus is needed for developing new treatments for cancer. Phytochemicals from Angelica species possess potential as anticancer agents, requiring further research for the development of effective, low-cost, and low-toxicity cancer treatments compared to synthetic antitumor drugs.

Evaluation of the gastroprotective and ulcer healing properties by Fridericia chica (Bonpl.) L.G. Lohmann hydroethanolic extract of leaves.

ETHNOPHARMACOLOGICAL RELEVANCE: Fridericia chica (Bonpl.) L.G. Lohmann (Bignoniaceae), is a climber native to Brazil, found in all Brazilian biomes. It is mostly known in Brazil as "carajiru," and home medicines made from the leaves have been used to cure disorders including stomach ulcers and other gastrointestinal disorders. AIM OF THE STUDY: The objective of the study was to investigate the F. chica hydroethanolic extract of leaves (HEFc) preventative and curative antiulcer gastrointestinal efficacy as well as the mechanisms of action using in vivo rodent models. MATERIALS AND METHODS: F. chica was collected in the municipality of Juína, Mato Grosso, and its leaves were used to prepare the extract by maceration technique (70% hydroethanol in the 1:10 ratio, w/v) to obtain the HEFc. The chromatographic analysis of HEFc was carried out by High Performance Liquid Chromatography-Photo Diode Array-Electrospray Ionization-Mass Spectrometry (HPLC-PDA-ESI-MS)- LCQ Fleet™ system. To determine the potential antiulcer potential of HEFc (1, 5 and 20 mg/kg, p.o.), the gastroprotective activity was assessed in various animal models of stomach ulcers caused by acidified ethanol, water constraint stress, indomethacin, (acute), and acid acetic (chronic). Additionally, the prokinetic properties of the HEFC were assessed in mice. The gastroprotective underlying mechanisms were evaluated by the histopathological analysis and determination of gastric secretion (volume, free and total acidity), gastric barrier mucus, activation of PGs, NO, K +ATP channels, α2-adrenoceptor, antioxidant activity (GSH, MPO and MDA), NO and mucosal cytokines (TNF-α, IL-1ß, and IL-10) levels. RESULTS: The chemical composition of HEFc was analyzed and apigenin, scutellarin, and carajurone were identified. HEFc (1, 5 and 20 mg/kg) showed effect against acute ulcers induced by HCl/EtOH with a reduction in the ulcerated area of 64.41% (p < 0.001), 54.23% (p < 0.01), 38.71% (p < 0.01), respectively. In the indomethacin experiment, there was no change in the doses tested, whereas in the water immersion restraint stress ulcer there was a reduction of lesions at doses of 1, 5, and 20 mg/kg by 80.34% (p < 0.001), 68.46% (p < 0.01) and 52.04% (p < 0.01). HEFc increased the mucus production at doses of 1 and 20 mg/kg in 28.14% (p < 0.05) and 38.36% (p < 0.01), respectively. In the pyloric ligation-induced model of gastric ulceration, the HEFc decreased the total acidity in all doses by 54.23%, 65.08%, and 44.40% (p < 0.05) and gastric secretory volume in 38.47% at dose of 1 mg/kg (p < 0,05) and increased the free acidity at the dose of 5 mg/kg by 11.86% (p < 0.05). The administration of EHFc (1 mg/kg) showed a gastroprotective effect possibly by stimulating the release of prostaglandins and activating K+ATP channels and α2-adrenoreceptors. Also, the gastroprotective effect of HEFc involved an increase in CAT and GSH activities, and a reduction in MPO activity and MDA levels. In the chronic gastric ulcer model, the HEFc (1, 5 and 20 mg/kg) decreased the ulcerated area significantly (p < 0.001) at all doses by 71.37%, 91.00%, and 93.46%, respectively. In the histological analysis, HEFc promoted the healing of gastric lesions by stimulating the formation of granulation tissue and consequently epithelialization. On the other hand, regarding the effect of HEFc on gastric emptying and intestinal transit, it was observed that the extract did not alter gastric emptying, but there was an increase in intestinal transit at the dose of 1 mg/kg (p < 0.01). CONCLUSION: These outcomes confirmed the advantages of Fridericia chica leaves for the treatment of stomach ulcers, which are well-known. HEFc was discovered to have antiulcer characteristics through multitarget pathways, which might be related to an increase in stomach defense mechanisms and a decrease in defensive factor. HEFc can be regarded as a potential new antiulcer herbal remedy because of its antiulcer properties, which may be attributed to the mixture of flavonoids, apigenin, scutellarin and carajurone.

Phytotherapy in paediatric skin disorders - A systematic literature review.

OBJECTIVES: Although skin disorders in children and adolescents are increasingly treated with phytotherapies in practice, there are very few studies investigating this topic, and no systematic review exists that summarizes the current state of research. This review examines which herbal medicines show to be effective to treat atopic dermatitis, diaper dermatitis, and skin lesions or wounds. METHODS: Clinical studies were searched according to PRISMA-guidelines in the medical databases of PubMed, EMBASE, and CINAHL and summarised in a systematic review. RESULTS: Among the 429 articles screened, 17 studies with a total of 2358 participants were identified that suited our inclusion criteria. Thereof seven studies each on the treatment of atopic dermatitis and skin lesions or wounds and three on diaper dermatitis. The phytotherapeutics investigated were based on the following herbs: Evening primrose, blackcurrant, polypodium leucotomos, calendula, aloe vera, chamomile, comfrey, hamamelis, olive, hypericum, neem, white oak, and myrrh. They have mainly been analysed in randomized controlled trials, but also in (long-term) observational studies, prospective trials and case series. CONCLUSIONS: Based on the application of the Jadad score, eight out of 17 of the studies examined were of low quality. Yet we found some indication that evening primrose oil may be effective for treating atopic dermatitis in children, while comfrey appears to have a positive effect on wound healing. Interestingly, none of the studies found positive effects for treating skin disorders with aloe vera or chamomile.

Traditional medicine herbs as natural product matrices in cancer chemoprevention: A trans pharmacological perspective (scoping review).

Emerging evidence on molecular biology related to tumors, inflammation, and immunity, highlights their architectural commonality shifting cancer treatment paradigms toward more economical prevention than treatment. Statistical surveys reveal exponentially growing herbal drug supplementation in cancer worldwide as vast pre-clinical and clinical data unravel their multi-mechanistic pharmacology. The integrative oncological approach calls for more "holistic" principles to be amalgamated into cancer care. New cancer drug development from herbs need not be limited by the archetypal 'RCT-Standardization' bottlenecks. Based on comprehensive literature scoping as per Prisma-ScR guidelines, we herein concurrently reviewed evidence-based research reports of selected Indian Traditional Medicine (ITM) herbs of anticancer repute in parallel with their holistic therapeutics; a rationalistic exploration of ITM's scientific genre. Their synergy effect on cancer revisited using a trans-pharmacological approach validates ITM's seemingly simplistic health/disease equation model, showing a fresh new avenue for re-purposing whole herbal drug complexes in cancer management. Herbal drugs as per ITM are natural matrices whose dynamics of interaction in the etiopathology of cancer are conceptually and mechanistically integrative. Lateral perspective to the same as laid out in this review holds the key to their effectual development as more tangible cancer chemopreventives/new drug targets/leads if not as new pharmacological tools.

Desert Endemic Plants in Algeria: A Review on Traditional Uses, Phytochemistry, Polyphenolic Compounds and Pharmacological Activities.

Due to their robust antioxidant capabilities, potential health benefits, wide variety of biological activities, and strong antioxidant qualities, phenolic compounds are substances that have drawn considerable attention in recent years. The main goal of the review is to draw attention to saharian Algerian medicinal plants and the determination of their bioactivity (antioxidant, anti-cancer, and anti-inflammatory importance), and to present their chemical composition as well as in vivo and in vitro studies, clinical studies, and other studies confirming their real impact on human health. Research results have revealed a rich variety of medicinal plants used to treat various disease states in this region. Based on in vivo and in vitro studies, biological activity, and clinical studies, a list of 34 species of desert plants, belonging to 20 botanical families, useful both in preventive actions and in the treatment of neoplastic diseases has been established, and polyphenolic compounds have been identified as key to the health potential of endemic diseases and desert plants. It has been shown that people who follow a diet rich in polyphenols are less prone to the risk of many cancers and chronic diseases, such as obesity and diabetes. In view of the increasing antioxidant potential of these plant species, as well as the increasing trade in herbal products from the Sahara region, phytosanitary and pharmaceutical regulations must change in this respect and should be in line with Trade Related Aspects of Intellectual Property Rights (TRIPS), and the sustainable use and development of plant products must be addressed at the same time.
