Investigation of the Potential of Selected Food-Derived Antioxidants to Bind and Stabilise the Bioactive Blue Protein C-Phycocyanin from Cyanobacteria Spirulina. Int J Mol Sci 2023; 25:229. [PMID: 38203400 PMCID: PMC10779248 DOI: 10.3390/ijms25010229] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/29/2023] [Revised: 12/19/2023] [Accepted: 12/20/2023] [Indexed: 01/12/2024] Open
Abstract
Blue C-phycocyanin (C-PC), the major Spirulina protein with innumerable health-promoting benefits, is an attractive colourant and food supplement. A crucial obstacle to its more extensive use is its relatively low stability. This study aimed to screen various food-derived ligands for their ability to bind and stabilise C-PC, utilising spectroscopic techniques and molecular docking. Among twelve examined ligands, the protein fluorescence quenching revealed that only quercetin, coenzyme Q10 and resveratrol had a moderate affinity to C-PC (Ka of 2.2 to 3.7 × 105 M-1). Docking revealed these three ligands bind more strongly to the C-PC hexamer than the trimer, with the binding sites located at the interface of two (αβ)3 trimers. UV/VIS absorption spectroscopy demonstrated the changes in the C-PC absorption spectra in a complex with quercetin and resveratrol compared to the spectra of free protein and ligands. Selected ligands did not affect the secondary structure content, but they induced changes in the tertiary protein structure in the CD study. A fluorescence-based thermal stability assay demonstrated quercetin and coenzyme Q10 increased the C-PC melting point by nearly 5 °C. Our study identified food-derived ligands that interact with C-PC and improve its thermal stability, indicating their potential as stabilising agents for C-PC in the food industry.

Biomolecules 2023; 13:1444. [PMID: 37892126 PMCID: PMC10604708 DOI: 10.3390/biom13101444] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/30/2023] [Revised: 09/20/2023] [Accepted: 09/22/2023] [Indexed: 10/29/2023] Open
Abstract
Neurodegenerative diseases (NDs) are characterized by progressive and irreversible neuronal loss, accompanied by a range of pathological pathways, including aberrant protein aggregation, altered energy metabolism, excitotoxicity, inflammation, and oxidative stress. Some of the most common NDs include Alzheimer's Disease (AD), Parkinson's Disease (PD), Multiple Sclerosis (MS), Amyotrophic Lateral Sclerosis (ALS), and Huntington's Disease (HD). There are currently no available cures; there are only therapeutic approaches that ameliorate the progression of symptoms, which makes the search for new drugs and therapeutic targets a constant battle. Cyanobacteria are ancient prokaryotic oxygenic phototrophs whose long evolutionary history has resulted in the production of a plethora of biomedically relevant compounds with anti-inflammatory, antioxidant, immunomodulatory, and neuroprotective properties, that can be valuable in this field. This review summarizes the major NDs and their pathophysiology, with a focus on the anti-neurodegenerative properties of cyanobacterial compounds and their main effects.

Abstract
In this study, the interaction mechanism of bovine serum albumin (BSA) with tannic acid (TA) was investigated by spectroscopic and computational approaches and further validated using circular dichroism (CD), differential scanning calorimetry (DSC) and molecular docking techniques. The fluorescence spectra showed that TA bound to BSA and underwent static quenching at a single binding site, which was consistent with the molecular docking results. And the fluorescence quenching of BSA by TA was dose-dependent. Thermodynamic analysis indicated that hydrophobic forces dominated the interaction of BSA with TA. The results of circular dichroism showed that the secondary structure of BSA was slightly changed after coupling with TA. Differential scanning calorimetry showed that the interaction between BSA and TA improved the stability of the BSA-TA complex, and the melting temperature increased to 86.67 °C and the enthalpy increased to 264.1 J g-1 when the ratio of TA to BSA was 1.2 : 1. Molecular docking techniques revealed specific amino acid binding sites for the BSA-TA complex with a docking energy of -12.9 kcal mol-1, which means the TA is non-covalently bound to the BSA active site.

Abstract
Spirulina platensis was first isolated from Lake Texcoco by Aztecs in the sixteenth century. In 2012, spirulina was considered to be safe dietary supplement by the Food and Drug Administration (FDA). Spirulina is a cyanophytic microalgae that is often considered as single cell protein. It contains many essential amino acids, proteins, fatty acids, antioxidant pigments, carotenoids, and cyanogenic pigments, that is, phycocyanobilins and phycocyanins (Eriksen, Appl Microbiol Biotechnol, 80(1):1-4, 2008). Components of spirulina are investigated for many health benefits and for pharmaceutical uses (Karkos et al., Spirulina in clinical practice: evidence-based human applications). Spirulina has been found to have a role in growth, immunity (Wu et al., Arch Toxicol, 90(8):1817-40, 2016), antioxidant (Wu et al., Arch Toxicol, 90(8):1817-40, 2016), antiviral (Ayehunie et al., J Acquir Immune Defic Syndr Hum Retrovirol, 18(1):7-12, 1998), antitoxicologic, anti-cancerogenic (Hirahashi et al., Int Immunopharmacol, 2(4):423-34, 2002), antidiabetic (Layam and Reddy, Diabetol Croat, 35(2):29-33, 2006), and neuroprotective properties. In this study, we focused on spirulina components in anti-Parkinson's and anti-Alzheimer's activity. Four potential targets, two for each activity, that is, structure of parkinE3 ligase (PDB ID:4I1H) and structure of BACE bound to 5-(3-(5-chloropyridin-3-yl)phenyl)-5-cyclopropyl-2-imino-3-methylimidazolidin-4one (PDBI D:4DJx) for anti-Parkinson's activity and structure of human MAO B in complex with selective inhibitor safinamide (PDB ID:2V5Z) and crystal structure of human BACE-1 in complex with CNP520(PDB ID:6EQM) for anti-Alzheimer's activity, have been selected. The in silico results and scoring of virtual screening, that is, molecular docking, were compared with commonly used marketed drugs such as levodopa for Parkinson's disease (PD) and rivastigmine (Rösler et al., BMJ, 318(7184):633-40, 1999) for Alzheimer's disease.

Abstract
Serum albumin (SA) is the most abundant extracellular chaperone protein presenting in various bodily fluids. Recently, several studies have revealed molecular mechanisms of SA in preventing the amyloid formation of amyloidogenic proteins. However, our insight into the mechanism SA employed to sense and regulate the folding states of full-length native proteins is still limited. Addressing this question is technically challenging due to the intrinsic dynamic nature of both chaperones and clients. Here using nuclear magnetic resonance spectroscopy, we show SA modifies the folding free energy landscape of clients and subsequently alters the equilibria between different compact conformations of its clients, resulting in the increased populations of excited states of client proteins. This modulation of client protein conformation by SA can change the client protein activity in a way that cannot be interpreted on the basis of its ground state structure; therefore, our work provides an alternative insight of SA in retaining a balanced functional proteome.

Abstract
Spirulina is a microscopic, filamentous cyanobacterium that grows in alkaline water bodies. It is extensively utilized as a nutraceutical food supplement all over the world due to its high levels of functional compounds, such as phycocyanins, phenols and polysaccharides, with anti-inflammatory, antioxidant, immunomodulating properties both in vivo and in vitro. Several scientific publications have suggested its positive effects in various pathologies such as cardiovascular diseases, hypercholesterolemia, hyperglycemia, obesity, hypertension, tumors and inflammatory diseases. Lately, different studies have demonstrated the neuroprotective role of Spirulina on the development of the neural system, senility and a number of pathological conditions, including neurological and neurodegenerative diseases. This review focuses on the role of Spirulina in the brain, highlighting how it exerts its beneficial anti-inflammatory and antioxidant effects, acting on glial cell activation, and in the prevention and/or progression of neurodegenerative diseases, in particular Parkinson’s disease, Alzheimer’s disease and Multiple Sclerosis; due to these properties, Spirulina could be considered a potential natural drug.
