Int J Biol Macromol 2024; 269:131810. [PMID: 38677669 DOI: 10.1016/j.ijbiomac.2024.131810] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/02/2024] [Revised: 04/04/2024] [Accepted: 04/11/2024] [Indexed: 04/29/2024]
Abstract
DNA is essential in biological processes as it directs transcription and translation assisting in RNA and protein synthesis. Extended periods of elevated blood glucose levels cause non-enzymatic DNA glycation, which results in the formation of DNA-AGEs and the production of free radicals, causing structural perturbation of DNA. In this work, we have investigated the glycation of calf thymus (ct-DNA) DNA and examined its inhibition by two anthraquinone derivatives, purpurin and aloin. Ribose sugar served as the glycating agent inducing non-enzymatic glycation of DNA and subsequent DNA-AGEs formation. UV-vis and fluorescence spectroscopic methods were utilized to characterize DNA-AGE formation in vitro. Circular dichroism (CD) spectroscopy was used to observe the structural disruption of DNA caused by glycation. The changes in AGEs fluorescence intensity and melting temperature (Tm) were measured to assess the inhibition of glycation process by aloin and purpurin. These derivatives demonstrated inhibitory effects via binding to glycating sites of ct-DNA or by scavenging free radicals generated during glycation. The current study elucidates the inhibitory actions of aloin and purpurin on DNA glycation, suggesting their possible applications in mitigating the adverse consequences linked to increased ribose concentrations.

Abstract
The aim of this study was to investigate the use of Arbutus unedo L. fruits for the production of functional foods by three-dimensional printing (3DP). First, the biological activity of the fruits was investigated in vitro, followed by 3DP with different starch types and proportions using two 3DP programs. All 3DP samples were characterized for their bioactive, antioxidant, physicochemical and rheological properties. In terms of biological activity, the recommended daily dose of polyphenols from the aqueous extract of A. unedo can protect the integrity of DNA. Moreover, it could be useful as an antimicrobial agent. All 3DP parameters significantly affected bioactive compounds and antioxidant capacity. The 3DP products were found to be a good source of polyphenols (632.60 mg/100 g), among which condensed tannins were predominant (42 %). In conclusion, the fruits of A. unedo should be considered as a sustainable resource for the production of innovative functional foods with 3DP.

Abstract
The present study is focused on the antimicrobial, antioxidant, cytotoxic, and DNA protective effects of methanol extract obtained from R. digitellata, R. fastigiata, R. fraxinea, and R. polymorpha species that are distributed in Turkey. The highest total phenol content was determined in R. digitellata (144.6 mgGAE/gextract ), and the highest total amount of flavonoids was found in R. fastigiata (20.40 mgGAE/gextract ). The content of usnic acid was determined by High-Performance Liquid Chromatography (HPLC) and the highest amount was found in R. digitellata. DPPH (1,1-diphenyl-2-picrylhydrazyl) and ABTS [2,2'-azinobis(3-ethylbenzathiazoline-6-sulfonic acid)] radical scavenging methods were used for antioxidant activity. R. fraxinea showed the highest DPPH⋅ and ABTS+ ⋅ scavenging activity. In addition, the DNA protective effect was investigated using pBR322 plasmid DNA, and; all studied species were found to have DNA protective effects. The antibacterial activity was investigated using the disc diffusion method, and the R. digitellata methanol extract showed the best results with a 12.35 mm zone on Proteus mirabilis. On the human lung cancer (A549) and breast cancer (MDA-MB-231) cell lines, cytotoxic activity was assessed using an MTT assay. All lichen extracts were found to have a significant cytotoxic effect on both cancer cell lines at 1000 μg/mL concentration. These results suggest that Ramalina species may be potential candidates for developing new phytopharmaceuticals and functional components.

On valorization of solvent extracts of Terminalia arjuna (arjuna) upon DNA scission and free radical scavenging improves coupling responses and cognitive functions under in vitro conditions. Sci Rep 2021; 11:10656. [PMID: 34017022 PMCID: PMC8137696 DOI: 10.1038/s41598-021-88710-w] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/05/2019] [Accepted: 04/06/2021] [Indexed: 11/22/2022] Open
Abstract
Chronic diseases have been treated using the phytochemical concepts of ethnomedicinal plant-derived herbal products. Terminalia arjuna, a significant ethnomedicinal plant, was revisited and reconnoitred for antioxidant, free radical scavenging, and DNA nicking inhibiting activity under H2O2 conditions using 21 solvent extracts. Ferric reducing antioxidant power (FRAP), 2,2-diphenyl-1-picrylhydrazyl (DPPH), 2,2′-azino-bis-3-ethylbenzothiazoline-6-sulphonic acid, and nitrous oxide scavenging (%) were found to have a strong positive association and interaction (PCA 1 explains 84.54% variation) with ethanol bark (Etoh-AB) (Meoh-AF). TPC (144.67–1794 µg/mL GAE) and TFC (2.5–34 µM Fe(II)/g were highest in Etoh-AB. In a pattern of combined solvent extracts, Etoh-AB had the highest antioxidant capacity, accompanied by Etoh-AL ≥ Meoh-AB ≥ Dw-AF. With R2 = 0.94, the DNA nicking inhibition behaviour parameters relative front, relative quantity, band (%), and lane (%) formed a positive significant (p < 0.01) connection. For the first time, we show that Etoh-AB nicks supercoiled, circular plasmid DNA in a way that is comparable to normal antioxidants. Normal antioxidants with the ability to prevent DNA nicking include Butylated hydroxy anisole < Butylated hydroxy toluene < ascorbic acid < and Gallic acid. Gallic acid (m/z 170.0208 g/mol) and Ellagic acid (m/z 302.0063 g/mol were present in high concentrations in solvent extracts. 0.48 mg was found to be the effective concentration for inhibiting relative DNA nicking. The current study is the first of its kind to show that steroid concentrations are higher in bark fractions of acetone, ethanol, and methanol. Furthermore, T. arjuna solvent extracts provide a wealth of information on phytochemical profiling, antioxidant ability, and DNA nicking inhibition, which may be useful for exploring the natural way and further research to develop a remedy against geriatric chronic disease. Despite the fact that ethanol is very close to methanol in terms of solvent toxicity, the current study identified it as the preferred solvent. Thus, the current research revisits previous studies and explores the potentiality of non-polar and polar aprotic and polar protic solvent systems, which lend credence to bioactive compounds that may be useful in isolating and formulating safe and cost effective herbal medicament for livestocks and aquaculture, and drugs for deoxygenerative human diseases, and can also be investigated further to instil environmental frugality.

Abstract
Launaea taraxacifolia (Willd.) Amin ex C. Jeffrey is a herb found mostly in tropical Africa. The plant, commonly found in West Africa, is used in the management of many diseases including cardiovascular, respiratory, haematological, endocrine, and metabolic diseases in Ghana, Nigeria, Benin, Serra Leone, and Senegal. This piece provides comprehensive and updated information on the traditional uses, phytochemical constituents, and pharmacological and toxicological information available on Launaea taraxacifolia to support its medicinal uses and also unearth knowledge gaps for future studies. An electronic literature search using search engines, namely, Google Scholar, ScienceDirect, and PubMed, was carried out to obtain information on the plant. Both common and scientific names of the plant were used as keywords for the search process. This paper captured information on Launaea taraxacifolia from 1985 to 2018. The search revealed that the leaves of the plant possess nutritional/pharmacological effects on diseases such as diabetes mellitus, hypertension, cancer, malaria, bacterial infections, and arthritis. The leaf has been shown to be a rich source of phytoconstituents such as flavonoids, phenolic acids, tannins, alkaloids, glycosides, coumarins, triterpenoids, ascorbic acid, lycopene, and β-carotene. Also, isolated phytoconstituents as well as the safety profile of the plant have been documented. This review on Launaea taraxacifolia has provided a one-stop documentation of information in support of the several purported ethnopharmacological uses of the plant. It also reveals information gaps such as the need to research into its pharmacokinetics, interactions with drugs of importance, and its development into a plant-based drug in order to expand its clinical use.
