Anywar G, Muhumuza E. Bioactivity and toxicity of coumarins from African medicinal plants. Front Pharmacol 2024; 14:1231006. [PMID: 38273831 PMCID: PMC10809390 DOI: 10.3389/fphar.2023.1231006] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/29/2023] [Accepted: 12/18/2023] [Indexed: 01/27/2024] Open
Abstract
Introduction: Coumarins are naturally occuring metabolites from plants and a few micro-organisms. They have been widely used in the food and drug industry in their natural or synthetic forms. Numerous coumarins possess several biological activities such as anti-inflammatory, anti-ulcers, anti-tumour, anti-microbial, anti-coagulant. The aim of this study was to assess the bioactivity, and toxicity of coumarins from African medicinal plants. Methods: We searched online databases and search engines such as PubMed, Google Scholar and Web of Science for key terms such as coumarins, toxicity, bioavailability, bioactivity with appropriate Boolean operators. Only full-length research articles published in English between 1956 to 2023 were reviewed. Results: We recorded 22 coumarins from 15 plant species from Africa. Most of the plant species (33%) were from North Africa. These were followed by East Africa at 21%, then West, and Central Africa at 18.2% each. Most of the coumarins (21.3%) were isolated from the entire plant and the leaves (19.1%) and most of them (46.7%) had some antimicrobial activity. Five coumarins viz osthole, pseudocordatolide C & calanolide, chartreusin and esculetin had either antitumor or anticancer activity. Six coumarins had varying levels and types of toxicity ranging from inhibiting blood clotting as anticoagulants, to cytotoxic effects, causing hyperventilation, tremor, & photophobia, pulmonary haemorrhage, carcinogenic activity, severe neurotoxicity, hepato- and phototoxicity. Conclusion: Several African medicinal plants are sources of various coumarins that possess several biological activities as well as toxicities. This calls for more research into their safety and efficacy because of their wide spread applications as therapeutic agents.

[PMID: 37308634 DOI: 10.1007/s10787-023-01256-3] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/23/2023] [Accepted: 05/24/2023] [Indexed: 06/14/2023]
Abstract
Coumarin, a plant secondary metabolite, has various pharmacological activities, including antioxidant stress and anti-inflammatory effects. Umbelliferone, a common coumarin compound found in almost all higher plants, has been extensively studied for its pharmacological effects in different disease models and doses with complex action mechanisms. This review aims to summarize these studies and provide useful information to relevant scholars. The pharmacological studies demonstrate that umbelliferone has diverse effects such as anti-diabetes, anti-cancer, anti-infection, anti-rheumatoid arthritis, neuroprotection, and improvement of liver, kidney, and myocardial tissue damage. The action mechanisms of umbelliferone include inhibition of oxidative stress, inflammation, and apoptosis, improvement of insulin resistance, myocardial hypertrophy, and tissue fibrosis, in addition to regulation of blood glucose and lipid metabolism. Among the action mechanisms, the inhibition of oxidative stress and inflammation is the most critical. In short, these pharmacological studies disclose that umbelliferone is expected to treat many diseases, and more research should be conducted.

Abstract
Plant-based natural products have shaped traditional knowledge systems due to their numerous biological and pharmacological utility. However, in addition to their extensive utilization, some of these plants are also known for their toxicological properties. Since the foundation of human civilization, these toxic plants were used for fishing, hunting and safeguarding against enemies. In this study, a total of five plant species used in ethnofishery were considered for the toxicological study. The toxicities of these plants were evaluated using Brine Shrimp Lethality Assay (BSLA) and LC50 values were estimated. All the plants have displayed the toxic effect and have been graded to be highly toxic (i.e., LC50 of 0-100 μg/ml or LC50 < 1000 μg/ml). Furthermore, with the lowest LC50 (0.14 in 12 h of incubation), the plant species D. scandens was reported to be the most toxic. The toxic plants have an important role in rural livelihood; however, if the concentration of these compounds from poisonous plants reaches a high concentration in the vulnerable biological system, it could bring a devastating health-related issue for the frequent consumers.

(±)-Catechin—A Mass-Spectrometry-Based Exploration Coordination Complex Formation with FeII and FeIII. Cells 2022; 11:cells11060958. [PMID: 35326409 PMCID: PMC8946835 DOI: 10.3390/cells11060958] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/09/2021] [Revised: 03/03/2022] [Accepted: 03/07/2022] [Indexed: 02/06/2023] Open
Abstract
Catechin is an extensively investigated plant flavan-3-ol with a beneficial impact on human health that is often associated with antioxidant activities and iron coordination complex formation. The aim of this study was to explore these properties with FeII and FeIII using a combination of nanoelectrospray-mass spectrometry, differential pulse voltammetry, site-specific deoxyribose degradation assay, FeII autoxidation assay, and brine shrimp mortality assay. Catechin primarily favored coordination complex formation with Fe ions of the stoichiometry catechin:Fe in the ratio of 1:1 or 2:1. In the detected Fe–catechin coordination complexes, FeII prevailed. Differential pulse voltammetry, the site-specific deoxyribose degradation, and FeII autoxidation assays proved that coordination complex formation affected catechin’s antioxidant effects. In situ formed Fe–catechin coordination complexes showed no toxic activities in the brine shrimp mortality assay. In summary, catechin has properties for the possible treatment of pathological processes associated with ageing and degeneration, such as Alzheimer’s and Parkinson’s diseases.

Siewert B, Stuppner H. The photoactivity of natural products - An overlooked potential of phytomedicines? PHYTOMEDICINE : INTERNATIONAL JOURNAL OF PHYTOTHERAPY AND PHYTOPHARMACOLOGY 2019; 60:152985. [PMID: 31257117 DOI: 10.1016/j.phymed.2019.152985] [Citation(s) in RCA: 42] [Impact Index Per Article: 8.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/14/2019] [Revised: 06/07/2019] [Accepted: 06/08/2019] [Indexed: 06/09/2023]
Abstract
BACKGROUND Photoactivity, though known for centuries, is only recently shifting back into focus as a treatment option against cancer and microbial infections. The external factor light is the ingenious key-component of this therapy: Since light activates the drug locally, a high level of selectivity is reached and side effects are avoided. The first reported photoactive medicines were plant extracts. Synthetic entities (so-called photosensitizers PSs), however, paved the route towards the clinical approval of the so-called photodynamic therapy (PDT), and thus natural PSs took a backseat in the past. HYPOTHESIS Many isolated bioactive phytochemicals hold a hidden photoactive potential, which is overlooked due to the reduced common awareness of photoactivity. METHODS A systematic review of reported natural PSs and their supposed medicinal application was conducted by employing PubMed, Scifinder, and Web of Science. The identified photoactive natural products were compiled including information about their natural sources, their photoyield, and their pharmacological application. Furthermore, the common chemical scaffolds of natural PS are shown to enable the reader to recognize potentially overlooked natural PSs. RESULTS The literature review revealed over 100 natural PS, excluding porphyrins. The PSs were classified according to their scaffold. Thereby it was shown that some PS-scaffolds were analyzed in a detailed way, while other classes were only scarcely investigated, which leaves space for future discoveries. In addition, the literature revealed that many PSs are phytoalexins, thus the selection of the starting material significantly matters in order to find new PSs. CONCLUSION Photoactive principles are ubiquitous and can be found in various plant extracts. With the increasing availability of light-irradiation setups for the identification of photoactive natural products, we anticipate the discovery of many new natural PSs in the near future. With the accumulation of chemically diverse PSs, PDT itself might finally reach its clinical breakthrough as a promising alternative treatment against multi-resistant microbes and cancer types.

Abstract
Seventy-one 7-oxycoumarins, 66 synthesized and 5 commercially sourced, were tested for their ability to inhibit growth in murine PAM212 keratinocytes. Forty-nine compounds from the library demonstrated light-induced lethality. None was toxic in the absence of UVA light. Structure-activity correlations indicate that the ability of the compounds to inhibit cell growth was dependent not only on their physiochemical characteristics, but also on their ability to absorb UVA light. Relative lipophilicity was an important factor as was electron density in the pyrone ring. Coumarins with electron withdrawing moieties - cyano and fluoro at C3 - were considerably less active while those with bromines or iodine at that location displayed enhanced activity. Coumarins that were found to inhibit keratinocyte growth were also tested for photo-induced DNA plasmid nicking. A concentration-dependent alteration in migration on neutral gels caused by nicking was observed.

Abstract
OBJECTIVES Assess whether an ancient text on herbal medicine accurately characterizes a class of herbal diuretics. DESIGN The Greek text of Dioscorides De materia medica was assessed for herbs stated to have diuretic activity, and then modern research was sought to determine how accurate the ancient assessment of these herbs was. RESULTS Of the 105 plants cited as having diuretic activity by Dioscorides, 56 (53.3%) genuses are confirmed as being diuretic in animal or human research. For another 38 (36.2%) genuses, no research related to diuresis could be identified. Six (5.7%) genuses had mixed results in modern research, whereas a mere 5 (4.8%) genuses were shown to not have diuretic activity. Considering the 67 genuses that were investigated, 56 (83.6%) were confirmed. CONCLUSION This analysis confirms that Dioscorides was accurate in determining the diuretic nature of herbs, raising the possibility that he was right about other therapeutic suggestions concerning herbs he made. For the remaining herbs that have not been assessed for diuretic effect, it is not yet known if Dioscorides was accurate. Our findings suggest that the 38 herbs Dioscorides categorized as diuretics that have not been studied for diuretic function are candidates for research in this regard.

Abstract
Phototoxicity can cause toxic responses such as edemas and lesions, and is one of the severe adverse effects that largely limit the use of these phototoxic drugs. Some traditional Chinese medicines (TCMs) and their constituents have been reported to be phototoxic. However, to date, their phototoxicity information is still very limited, and lacks systemic investigation. This article presents the phototoxicity potential of various types of TCMs and their active components in an effort to provide valuable information for drug research and discovery to mitigate phototoxicity concerns. Some potential mechanisms of action (MoAs) of phototoxicity are discussed. In addition, in vivo and in vitro phototoxicity assays are summarized this review.

Abstract
The chemical contamination of food is among the main public health issues in developing countries. With a view to find new natural bioactive products against fungi responsible for chemical contamination of staple food such as maize, the antifungal activity tests of scopoletin extracted from different components of the cassava root produced in Benin were carried out. The dosage of scopoletin from parts of the root (first skin, second skin, whole root, and flesh) was done by High Performance Liquid Chromatography. The scopoletin extract was used to assess the activity of 12 strains (11 strains of maize and a reference strain). The presence of scopoletin was revealed in all components of the cassava root. Scopoletin extracted from the first skin cassava root was the most active both as inhibition of sporulation (52.29 to 87.91%) and the mycelial growth (36.51-80.41%). Scopoletin extract from the cassava root skins showed significant inhibitory activity on the tested strains with fungicide concentration (MFC) between 0.0125 mg/mL and 0.1 mg/mL. The antifungal scopoletin extracted from the cassava root skins may be well beneficial for the fungal control of the storage of maize.

Abstract
The coumarin composition of Peucedanum palustre (L.) Moench populations growing in Finland was investigated. A total of 132 flowering P. palustre specimens from 43 locations in southern and central Finland were collected, divided into root, stem, leaf, and umbel samples, and analyzed by HPLC. HPLC coupled to high-resolution mass spectrometry was used to aid the identification of coumarins. A total of 13 coumarin-structured compounds were quantitatively analyzed from the samples. The coumarin profile of root samples was found to differ from the aerial plant parts. The main coumarins in roots were oxypeucedanin and columbianadin. In aerial parts, peulustrin isomers were the most abundant coumarin components. Umbels and leaves also contained a considerable amount of umbelliprenin, which was only found in traces in roots. Based on hierarchical cluster analysis of the coumarin profiles, some populations shared common characteristics. The most distinct property connecting certain populations was their high peulustrin content. Another notable common property between some populations was the high umbelliprenin content in aerial plant parts. Some populations were clustered together due to their low overall coumarin content.

Abstract
Coumarins are widely distributed, plant-derived, 2H-1-benzopyran-2-one derivatives which have attracted intense interest in recent years as a result of their diverse and potent pharmacological properties. Particularly, their effects on the central nervous system (CNS) have been established. The present review discusses the most important pharmacological effects of natural and synthetic coumarins on the CNS, including their interactions with benzodiazepine receptors, their dopaminergic and serotonergic affinity, and their ability to inhibit cholinesterases and monoamine oxidases. The structure-activity relationships pertaining to these effects are also discussed. This review posits that natural or synthetic coumarins have the potential for development in the therapy of psychiatric and neurodegenerative disorders, including Alzheimer's and Parkinson's diseases, schizophrenia, anxiety, epilepsy, and depression.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE The genus Peucedanum (Apiaceae) comprising more than 120 species is widely distributed in Europe, Asia and Africa. The ethnopharmacologial history of this genus indicated that some extracts of aerial and underground parts of several Peucedanum species have been used in folk medicine for treatment of various conditions, such as cough, cramps, pain, rheumatism, asthma and angina. This review focuses on ethnopharmacological uses of Peucedanum species, as well as the phytochemical, pharmacological and toxicological studies on this genus. Through this review, I intend to highlight the known and potential effects of the Peucedanum species or their isolated compounds and show which traditional medicine uses have been supported by pharmacological investigations. METHODS Information on the Peucedanum species was collected from scientific journals, books, thesis and reports via a library and electronic search (using Google Scholar, Pubmed, Scopus, Web of Science and ScienceDirect). This review covers the available literature from 1970 to the end of September 2013. RESULTS Although, there are about 120 species in this genus, so far many species have received no or little attention and most of pharmacological studies were performed on just about 20 species. Many phytochemical investigations on this genus confirmed that Peucedanum species are rich in essential oils and coumarins. The present review article shows that Peucedanum species have a wide spectrum of pharmacological activities and the most reported activities of Peucedanum plants come back to the presence of coumarins, flavonoids, phenolics and essential oils. CONCLUSIONS The present review confirms that some Peucedanum species have emerged as a good source of the traditional medicine for treatment of inflammation, microbial infections, cardiopulmonary diseases and provides new insights for further investigations on isolated compounds, especially on praeruptorins, to find novel therapeutics and aid drug discovery. However, for using Peucedanum species to prevent and treat various diseases, additional pharmacological studies to find the mechanism of action, safety and efficacy of them before starting clinical trials are required.

Abstract
Plants are used by humans in daily life in many different ways, including as food, herbal medicines, and cosmetics. Unfortunately, many natural plants and their chemical constituents are photocytotoxic and photogenotoxic, and these phototoxic phytochemicals are widely present in many different plant families. To date, information concerning the phototoxicity and photogenotoxicity of many plants and their chemical constituents is limited. In this review, we discuss phototoxic plants and their major phototoxic constituents; routes of human exposure; phototoxicity of these plants and their constituents; general mechanisms of phototoxicity of plants and phototoxic components; and several representative phototoxic plants and their photoactive chemical constituents.

ECOTOXICOLOGY AND ENVIRONMENTAL SAFETY 2008; 70:294-9.

Abstract
Landfills are used to dispose municipal solid wastes, and although on-site recycling in these places is an extensive practice in Latin America, diverse pollutants are incorporated into the leachates. The objective of this work was to establish relationships between composition and toxicity of leachates from the landfill of the city of Cartagena, Colombia. Leachates were characterized measuring Cd, Ni, Hg, Mn, Cu, and Pb concentrations, and physicochemical parameters including pH, conductivity, chemical oxygen demand (COD), and hardness. Bioassays were conducted diluting with synthetic sea water, recording toxicity against Artemia franciscana as median lethal concentrations (LC50 values) after 24 and 48 h exposure. Average LC(50) values oscillated between 3.20% and 39.33% (v/v). Multivariate analysis showed that toxicity was dependent on Cd and COD. The slope of the concentration-response curve correlated with Ni concentration independently from toxicity. Results suggest toxicity of these leachates depends on Cd concentrations associated with organic matter, this effect being modulated by Ni.

Abstract
The present work was undertaken to determine safety parameters of selected Mexican medicinal plants chosen on the basis of their frequency of medicinal use and commercial importance. The medicinal herbs included Amphipteryngium adstringens, Hintonia standleyana, Hintonia latiflora, Piper sanctum, Haemathoxylon brasiletto, Iostephane heterophylla, Valeriana procera, Arracacia tolucensis, Brickellia veronicaefolia, Scaphyglottis livida, Exostema caribaeum, Hippocratea excelsa, Ligusticum porteri, Poliomintha longiflora and Gnaphalium sp. In the acute toxicity studies in mice performed according to the Lorke procedure, Exostema caribaeum, Hippocratea excelsa, Ligusticum porteri and Poliomintha longiflora were the most toxic with LD(50) values between 1085 and 2mg/kg. The Ames test revealed that Gnaphalium sp. and Valeriana procera extracts induced mutations of S. typhimurium TA98 with or without the S9 microsomal fraction, and TA100 in the presence of the enzymatic fraction, respectively. The tincture of Valeriana procera, however, was non-mutagenic. Finally, in the Artemia salina lethality test Brickellia veronicaefolia, Arracacia tolucensis, Poliomintha longiflora and Piper sanctum caused significant mortality of the crustacean larvae with LC(50) in the range of 37-227 microg/mL.

Abstract
We describe an unusual case of phytophototoxicity induced by an herbal plant, Ruta graveolens, from the Rutaceae family. This common herb, also called rue, can be found throughout rural settings in the United States. When psoralens from rue come in contact with human skin that is subsequently exposed to ultraviolet A light, an impressive photoirritant reaction can occur. This report both clarifies the distinguishing features of photoirritant reactions versus photoallergic reactions and reviews the pathophysiology and clinical presentation of phytophotodermatitis. R. graveolens can be associated with an impressive photoirritant reaction and should not be used as an insect repellent.

Abstract
Brine shrimp assay-guided fractionation and isolation of the EtOAc soluble fraction of Phryma leptostachya L. (Phrymacaceae) gave two active compounds, phrymarolin II (1) and ursolic acid (2), which were identified by physicochemical and spectroscopic methods. Compound 1 exhibited potent lethality with LD50 value of 0.0013 microg/ml, whereas 2 showed moderate lethality with LD50 value of 27.0 microg/ml against brine shrimp. The cytotoxic activities of 1 and 2 were also evaluated against one murine and five human cancer cell lines employing the sulforhodamin B (SRB) method. Compound 2 exhibited cytotoxic activity against L1210 and SK-MEL-2 cells with ED50 values of 3.70 and 9.27 mg/ml, respectively, whereas 1 was devoid of any cytotoxic activity against all cancer cells tested.

Abstract
Antimicrobial screening against selected Gram-positive and Gram-negative bacteria, yeasts, mold, as well as plant pathogenic fungi, with emphasis on method optimization was carried out on methanol extracts prepared from seven plants grown in Finland. Sensitivity to the extracts was found to vary considerably among the micro-organisms, the extract from Petroselinum crispum and Ruta graveolens showing the highest toxicity against Rhizoctonia solani. The growth of Heterobasidium annosum was inhibited, whereas that of Phytophtora (cactorum) was promoted by all the extracts. The antibacterial and antifungal activities of six natural coumarin compounds were weak, except for the inhibitory effect against Fusarium culmorum.
