Interaction of eugenol-based anti-tuberculosis nanoemulsion with bovine serum albumin: A spectroscopic study including Rifampicin, Isoniazid, Pyrazinamide, and Ethambutol. Heliyon 2024; 10:e28306. [PMID: 38571616 PMCID: PMC10987999 DOI: 10.1016/j.heliyon.2024.e28306] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/31/2023] [Revised: 03/15/2024] [Accepted: 03/15/2024] [Indexed: 04/05/2024] Open
Abstract
Tuberculosis (TB), a deadly infectious disease, is primarily caused by the bacterium Mycobacterium tuberculosis. The misuse of antibiotics has led to the development of drug resistance, prompting researchers to explore new technologies to combat multidrug-resistant Tuberculosis (MDR TB). Phospholipid-based nanotherapeutics, such as nanoemulsions, are gaining traction as they enhance drug solubility, stability, and bioavailability. Our study focuses on the interaction between Bovine Serum Albumin (BSA) and a drug-loaded nanoemulsion based on Eugenol. This nanoemulsion incorporates Eugenol, Clove, cinnamon oil, and first-line anti-tuberculosis drugs like Rifampicin, Isoniazid, Pyrazinamide, and Ethambutol. The primary objective is to assess the biosafety profile of the nanoemulsion upon interaction with BSA. We employed Fluorescence, UV-visible, and Fourier Transform Infrared Spectroscopy (FTIR) to analyze this interaction. UV-visible spectroscopy detected changes in hydrophobicity due to structural alterations in BSA near the tryptophan residue, leading to the formation of ground-state complexes. Fluorescence spectroscopy demonstrated that the nanoemulsion effectively quenched fluorescence originating from tryptophan and tyrosine residues. Studies using synchronous and three-dimensional spectroscopy point to a potential modification of the aromatic environment of BSA by the nanoemulsion. Resonance light scattering spectra indicated the formation of large aggregates due to the interaction with the nanoemulsion. The second derivative FTIR spectra showed an increase in the magnitude of secondary structure bands, suggesting a conformational shift. This research has significant pharmacological implications for developing safer, more targeted drug delivery systems. The information obtained from the interaction of the nanoemulsion with the blood carrier protein is vital for the future development of superior carriers with minimal adverse effects on patients. It is crucial to remember that conformational changes brought on by drug-ligand complexes attaching to carrier proteins may have negative consequences. Therefore, this study enhances the in vitro evaluation of potential adverse effects of the nanoemulsion on serum proteins.

Abstract
AbstractFollowing recent work on new Tris hydroxymethyl aminomethane Schiff base derivatives were synthesized and characterized by using NMR (1H, 13C, and depth), FT‐IR, and Mass spectroscopy. The crystal structure of STB has been determined by X‐ray diffraction analysis. The binding interaction of the 3 chemically synthesized molecules with human serum albumin has been examined under the pH=7.40 through UV‐visible absorption and fluorescence spectroscopy analysis. The result obtained from the fluorescence experiment (1014) suggests a static mechanism of quenching. By utilizing fluorescence spectroscopy to determine the binding constant (Kb=106), it was determined which ligands have the highest affinity for HSA and that these ligands had changed the structure of HSA. Through hydrophobic interactions, the ligands bind to HSA on site I (subdomain II), according to thermodynamic parameters like enthalpy change (ΔHo), entropy change (ΔSo), and Gibbs free energy change (ΔGo). The result of 3D fluorescence spectra also showed that albumin conformational changes were brought on by these ligands. The results of the experiments were supported by DFT and molecular docking of ligands with HSA. Escherichia coli, Stap. aureus, Aspergillus niger, and Aspergillus flavus were tested for antimicrobial activity against the synthesized compounds respectively.

Abstract
Genistein is a naturally occurring polyphenolic molecule in the isoflavones group which is well known for its neuroprotection. In this review, we summarize the efficacy of genistein in attenuating the effects of memory impairment (MI) in animals. Scopus, PubMed, and Web of Science databases were used to find the relevant articles and discuss the effects of genistein in the brain, including its pharmacokinetics, bioavailability, behavioral effects, and some of the potential mechanisms of action on memory in several animal models. The results of the preclinical studies highly suggested that genistein is highly effective in enhancing the cognitive performance of the MI animal models, specifically in the memory domain, including spatial, recognition, retention, and reference memories, through its ability to reduce oxidative stress and attenuate neuroinflammation. This review also highlighted challenges and opportunities to improve the drug delivery of genistein for treating MI. Along with that, the possible structural modifications and derivatives of genistein to improve its physicochemical and drug-likeness properties are also discussed. The outcomes of the review proved that genistein can enhance the cognitive performance and ameliorate MI in different preclinical studies, thus indicating its potential as a natural lead for the design and development of a novel neuroprotective drug.

Abstract
The effect of manganese (Mn) on protein conformation is closely related to its chemical species. To further realize the behavior of different species of Mn in vivo, this study is designed to analyze the separate and simultaneous interactions of Mn(ii) and Mn(iii) with bovine serum albumin (BSA) using multi-spectroscopy. The results demonstrated that the interaction of Mn(ii) or Mn(iii) with BSA is a process of static quenching and Mn(iii) formed a more stable complex. The binding constants and thermodynamic constants indicated that a 1:1 complex was formed between Mn(ii)/Mn(iii) and BSA through a moderate binding force, and hydrophobic interaction played an important role in the binding. UV-Vis spectroscopy, synchronous fluorescence spectroscopy and three-dimensional fluorescence spectroscopy results revealed that the conformation changes in BSA induced by Mn(ii)/Mn(iii) binding. The results of the ternary systems suggested that both Mn species interfered the interaction of the other with BSA. The conformation of BSA may change more to adapt to the simultaneous binding to Mn (ii) and Mn (iii) when two Mn species coexist.

Abstract
Antitumor activity of plant-derived flavonoids has been researched during recent decades. Among them, genistein (Gen) stands out for showing cytotoxic activity against breast cancer cells. However, its low water solubility, limited bioavailability, and fast metabolism hinder its administration in chemopreventive therapies. To overcome these obstacles, bovine serum albumin nanovehicles (BSAnp) were obtained by a heat-induced self-assembly process at 70 °C and two aqueous medium pH (9.0 and 11.0) and assayed for the Gen loading. Thus, in this work, Gen loading in BSAnp was studied by spectroscopic techniques and compared with the one obtained for its stereoisomer, chrysin (Chrys). Results revealed that Gen binds to BSAnp via fluorescence quenching mechanism forming inclusion complexes. Compared to Chrys, Gen binding to BSAnp involved more molecules, whereas the association constant was similar for both flavonoids. In general, flavonoid loading in protein systems was strongly affected by the combined effects of BSA conformational state (native vs. aggregated), nanovehicle size, and flavonoid chemical structure. To evaluate the antitumor properties freeze-dried powders were obtained, and they were assayed in vitro after reconstitution by XTT technique and Annexin V-FITC flow cytometry against mouse mammary adenocarcinoma F3II cells. Gen-loaded BSAnp produced a significant decrease in cell viability compared with unloaded BSAnp systems, being the highest cytotoxic effects found for the lowest sized Gen-loaded BSAnp. The leading cytotoxicity mechanism for Gen-loaded systems was apoptosis. Summarizing, it can be concluded that BSAnp constitute versatile nanovehicles for potential flavonoid incorporation in pharmaceutical and nutraceutical matrices.

Abstract
Fifteen 7,4’- O-modified genistein amino acid derivatives are synthesized through nucleophilic substitution and hydrolysis, followed by condensation with diverse amino acid esters. The antiproliferative activity of all the synthesized compounds is evaluated against three cancer cell lines (MGC-803, HeLa, HCT-116) and one normal cell line (HUVEC) using 5-fluorouracil (5-Fu) as the positive control. The results show that methyl [2-({5-hydroxy-3-[4-(2-{[3-(4-hydroxyphenyl)-1-methoxy-1-oxopropan-2-yl]amino}-2-oxoethoxy)phenyl]-4-oxo-4 H-chromen-7-yl}oxy)acetyl] tyrosinate exhibits significant antiproliferative activity against the MGC-803 cell line with an IC50 value of 8.52 µM, and its inhibitory effects on HeLa and HCT-116 cancer cells are stronger than that of the positive control drug 5-Fu.

Abstract
This work aimed to evaluate the contribution of isoflavones and melatonin to the aqueous extract obtained from the coffee silverskin (CSE) antiglycative properties, which has not been previously studied. To achieve this goal, two model systems constituted by bovine serum albumin (BSA) and reactive carbonyls (glucose or methylglyoxal) in the presence or absence of pure phytochemicals (chlorogenic acid (CGA), genistein, and melatonin) and CSE were employed. Glucose was used to evaluate the effect on the formation of glycation products formed mainly in the early stage of the reaction, while methylglyoxal was employed for looking at the formation of advanced products of the reaction, also called methylglyoxal-derivative advanced glycation end products (AGE) or glycoxidation products. CGA inhibited the formation of fructosamine, while genistein and melatonin inhibited the formation of advanced glycation end products and protein glycoxidation. It was also observed that phenolic compounds from CSE inhibited protein glycation and glycoxidation by forming BSA-phytochemical complexes. CSE showed a significant antiglycative effect (p < 0.05). Variations in the UV-Vis spectrum and the antioxidant capacity of protein fractions suggested the formation of protein-phytochemical complexes. Fluorescence quenching and in silico analysis supported the formation of antioxidant-protein complexes. For the first time, we illustrate that isoflavones and melatonin may contribute to the antiglycative/antiglycoxidative properties associated with CSE. CGA, isoflavones, and melatonin composing CSE seem to act simultaneously by different mechanisms of action.
