Borsoi FT, Pastore GM, Arruda HS. Health Benefits of the Alkaloids from Lobeira ( Solanum lycocarpum St. Hill): A Comprehensive Review. PLANTS (BASEL, SWITZERLAND) 2024; 13:1396. [PMID: 38794466 PMCID: PMC11124789 DOI: 10.3390/plants13101396] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/23/2024] [Revised: 05/14/2024] [Accepted: 05/15/2024] [Indexed: 05/26/2024]
Abstract
Solanum is the largest genus within the Solanaceae family and has garnered considerable attention in chemical and biological investigations over the past 30 years. In this context, lobeira or "fruta-do-lobo" (Solanum lycocarpum St. Hill), a species predominantly found in the Brazilian Cerrado, stands out. Beyond the interesting nutritional composition of the fruits, various parts of the lobeira plant have been used in folk medicine as hypoglycemic, sedative, diuretic, antiepileptic, and antispasmodic agents. These health-beneficial effects have been correlated with various bioactive compounds found in the plant, particularly alkaloids. In this review, we summarize the alkaloid composition of the lobeira plant and its biological activities that have been reported in the scientific literature in the last decades. The compiled data showed that lobeira plants and fruits contain a wide range of alkaloids, with steroidal glycoalkaloid solamargine and solasonine being the major ones. These alkaloids, but not limited to them, contribute to different biological activities verified in alkaloid-rich extracts/fractions from the lobeira, including antioxidant, anti-inflammatory, anticancer, antigenotoxic, antidiabetic, antinociceptive, and antiparasitic effects. Despite the encouraging results, additional research, especially toxicological, pre-clinical, and clinical trials, is essential to validate these human health benefits and ensure consumers' safety and well-being.

Abstract
The European Commission asked EFSA for a scientific opinion on the risks for animal and human health related to the presence of glycoalkaloids (GAs) in feed and food. This risk assessment covers edible parts of potato plants and other food plants containing GAs, in particular, tomato and aubergine. In humans, acute toxic effects of potato GAs (α-solanine and α-chaconine) include gastrointestinal symptoms such as nausea, vomiting and diarrhoea. For these effects, the CONTAM Panel identified a lowest-observed-adverse-effect level of 1 mg total potato GAs/kg body weight (bw) per day as a reference point for the risk characterisation following acute exposure. In humans, no evidence of health problems associated with repeated or long-term intake of GAs via potatoes has been identified. No reference point for chronic exposure could be identified from the experimental animal studies. Occurrence data were available only for α-solanine and α-chaconine, mostly for potatoes. The acute dietary exposure to potato GAs was estimated using a probabilistic approach and applying processing factors for food. Due to the limited data available, a margin of exposure (MOE) approach was applied. The MOEs for the younger age groups indicate a health concern for the food consumption surveys with the highest mean exposure, as well as for the P95 exposure in all surveys. For adult age groups, the MOEs indicate a health concern only for the food consumption surveys with the highest P95 exposures. For tomato and aubergine GAs, the risk to human health could not be characterised due to the lack of occurrence data and the limited toxicity data. For horses, farm and companion animals, no risk characterisation for potato GAs could be performed due to insufficient data on occurrence in feed and on potential adverse effects of GAs in these species.

Abstract
Genotoxic compounds may be detoxified to non-genotoxic metabolites while many pro-carcinogens require metabolic activation to exert their genotoxicity in vivo. Standard genotoxicity assays were developed and utilized for risk assessment for over 40 years. Most of these assays are conducted in metabolically incompetent rodent or human cell lines. Deficient in normal metabolism and relying on exogenous metabolic activation systems, the current in vitro genotoxicity assays often have yielded high false positive rates, which trigger unnecessary and costly in vivo studies. Metabolically active cells such as hepatocytes have been recognized as a promising cell model in predicting genotoxicity of carcinogens in vivo. In recent years, significant advances in tissue culture and biological technologies provided new opportunities for using hepatocytes in genetic toxicology. This review encompasses published studies (both in vitro and in vivo) using hepatocytes for genotoxicity assessment. Findings from both standard and newly developed genotoxicity assays are summarized. Various liver cell models used for genotoxicity assessment are described, including the potential application of advanced liver cell models such as 3D spheroids, organoids, and engineered hepatocytes. An integrated strategy, that includes the use of human-based cells with enhanced biological relevance and throughput, and applying the quantitative analysis of data, may provide an approach for future genotoxicity risk assessment.

Abstract
The glycoalkaloids which are secondary metabolites from plants have proven to be of significant interest for their biological properties both in terms of their roles in plant biology and the effects they exhibit when ingested by humans. The main feature of the action of glycoalkaloids is their strong binding to 3β-hydroxysterols, such as cholesterol, to form complexes with the consequence that membrane structure is significantly perturbed, and leakage or release of contents inside cells or liposomes becomes possible. The glycoalkaloids have been studied for their ability to inhibit the growth of cancer cells and in other roles such as vaccine adjuvants and as synergistic agents when combined with other therapeutics. The glycoalkaloids have rich and complex physical behavior when interacting with model membranes for which many aspects are yet to be understood. This review introduces the general properties of glycoalkaloids and aspects of their behavior, and then summarizes their effects against model membrane systems. While there are many glycoalkaloids that have been identified, most physical or biological studies have focused on the readily available ones from tomatoes (α-tomatine), potatoes (α-chaconine and α-solanine), and eggplant (α-solamargine and α-solasonine).

Abstract
Over the past 30 years, the genus Solanum has received considerable attention in chemical and biological studies. Solanum is the largest genus in the family Solanaceae, comprising of about 2000 species distributed in the subtropical and tropical regions of Africa, Australia, and parts of Asia, e.g., China, India and Japan. Many of them are economically significant species. Previous phytochemical investigations on Solanum species led to the identification of steroidal saponins, steroidal alkaloids, terpenes, flavonoids, lignans, sterols, phenolic comopunds, coumarins, amongst other compounds. Many species belonging to this genus present huge range of pharmacological activities such as cytotoxicity to different tumors as breast cancer (4T1 and EMT), colorectal cancer (HCT116, HT29, and SW480), and prostate cancer (DU145) cell lines. The biological activities have been attributed to a number of steroidal saponins, steroidal alkaloids and phenols. This review features 65 phytochemically studied species of Solanum between 1990 and 2018, fetched from SciFinder, Pubmed, ScienceDirect, Wikipedia and Baidu, using "Solanum" and the species' names as search terms ("all fields").

In vitro and in vivo assessment of the genotoxicity and antigenotoxicity of the Filipendula hexapetala and Filipendula ulmaria methanol extracts. JOURNAL OF ETHNOPHARMACOLOGY 2015; 174:287-292. [PMID: 26303017 DOI: 10.1016/j.jep.2015.08.025] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/03/2015] [Revised: 07/24/2015] [Accepted: 08/20/2015] [Indexed: 06/04/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE The two species of Filipendula genus, Filipendula hexapetala Gilib. and Filipendula ulmaria (L.) Maxim are a traditional herbal medicine widely used to treat haemorrhoids, diarrhoea, fever, rheumatism and arthritic pain, kidney problems, to stop bleeding, and the common cold, as well as food supplements. However, no scientific study has been performed to validate genotoxic and/or antigenotoxic potentials of these two Filipendula species. AIM OF THE STUDY The aim of the present study was to examine the genotoxic and possible in vitro and in vivo DNA protection potential of methanol extracts of F. hexapetala and F. ulmaria. MATERIALS AND METHODS The genotoxicity of different concentrations of F. hexapetala and F. ulmaria methanol extracts from roots and aerial parts (20, 40 and 80 mg/ml), mixed with standard food for Drosophila, was evaluated in vivo in the anterior midgut of Drosophila melanogaster using a modified alkaline comet assay. The protective effects of the highest dose of extracts were observed in somatic cells of third-instar larvae against ethyl methanesulphonate (EMS)-induced genotoxicity. Also, DNA protection activity of methanol extracts from F. hexapetala and F. ulmaria (100, 200, and 400 μg/ml) against hydroxyl radical-induced DNA damage was determined under in vitro conditions. RESULTS The results showed that methanol extracts from the root and aerial part of F. hexapetala at a concentration of 20mg/ml indicated the absence of genotoxicity. Also, there were no statistically significant differences in total scores between any of the groups treated with F. ulmaria root extract and the negative control group, while F. ulmaria aerial part extract possess weak genotoxic effects depending on the concentrations. The percentage reduction in DNA damage was more evident in the group of larvae simultaneously treated with EMS and the highest dose of F. hexapetala root or aerial part extracts and F. ulmaria root extract (91.02, 80.21, and 87.5%, respectively) and less expressive in the group simultaneously treated with F. ulmaria aerial part extract (54.7%). F. hexapetala root and aerial part extracts and F. ulmaria root extract possess strong capabilities to protect DNA from being damaged by hydroxyl radicals. CONCLUSIONS It can be concluded that F. hexapetala root and aerial part extracts and F. ulmaria root extract demonstrated the absence of genotoxic activity. The extracts appeared to have antigenotoxic effect, reducing the levels of DNA damage induced by EMS by more than 80%. Also, F. hexapetala root and aerial part extracts and F. ulmaria root extracts could effectively protect against hydroxyl radical-induced DNA damage.
