Food Chem 2024; 436:137653. [PMID: 37832415 DOI: 10.1016/j.foodchem.2023.137653] [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: 06/29/2023] [Revised: 08/14/2023] [Accepted: 09/30/2023] [Indexed: 10/15/2023]
Abstract
Carotenoids, chlorophyll and phycocyanin are three types of photosynthetic pigments found in Spirulina that differ in colour, composition, stability, solubility, and commercial importance. Such diversity of structures creates a challenge to extract these pigments simultaneously from the same batch of raw material in an efficient and sustainable manner. This study demonstrates that water can be successfully used as a single solvent together with combined (non)mechanical cell membrane disruption techniques (ultrasonication, centrifugation, freezing/thawing cycle) to extract these photosynthetic pigments from the same batch. This water-based approach delivers a significant improvement in isolating green pigments, which are often overlooked during extraction due to a preference for blue and yellow pigments. Chlorophyll was quantitatively converted to its stable derivatives to carry out a comparative analysis of antioxidant properties (DPPH, TEAC, FRAP), singlet oxygen production and intracellular activities (MTT, ROS assays) using Caco-2 cells.

Fabrication of biodegradable cellulose acetate nanofibers containing Rose Bengal dye by electrospinning technique and their antiviral efficacy under visible light irradiation. CHEMOSPHERE 2024; 349:140897. [PMID: 38070613 DOI: 10.1016/j.chemosphere.2023.140897] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/09/2023] [Revised: 09/23/2023] [Accepted: 12/03/2023] [Indexed: 01/10/2024]
Abstract
Biodegradable cellulose acetate (CA) nanofibers containing Rose Bengal (RB) dye were fabricated by electrospinning technique. RB dye, an anionic photosensitizer, has been used in photodynamic therapy due to its excellent biocompatibility and ability to absorb light to generate reactive oxygen species (ROS), but has a decisive disadvantage of water solubility on infection prevention. Firstly, water-insoluble RB dye was synthesized through complexation with cationic ionic liquid (IL) for antiviral agents. The synthesized water-insoluble RB dyes were embedded into biodegradable CA nanofibers by electrospinning. The electrospun nanofibers passed both antiviral test for φx174 virus under visible light irradiation and biodegradability-test using enzymes. The fabricated RB nanofibers absorbed light and generated ROS to inactivate the virus. As a result, the log reduction (-Log10(N/N0)) of φx174 titer under visible light reached a detection limit of 5.00 within 30 min. Also, the fabricated nanofibers were degraded up to 34 wt % in 9 weeks by lipase and cellulase enzymes compared with non-biodegradable nanofibers.

Abstract
The strategic design, synthesis, and thorough characterizations of a redox-active BODIPY-based tripodal system (tri-BDP) displaying efficient aggregation-induced emission (AIE), great sensitivity toward the viscosity of a medium, ability for triplet photosensitization, singlet oxygen generation, and photooxidation have been described. The photophysical properties of tri-BDP in various solvents and in the solid state have been extensively investigated. It displayed efficient AIE and green (∼520) emission in acetonitrile/ether mixture and red (∼621 nm) emission in the solid state. Detailed viscosity-dependent studies suggested that it can act as a fluorescent molecular rotor. Triplet photosensitization, singlet oxygen generation, and photooxidation studies in the presence of 1,3-diphenylisobenzofuran and 1,5-dihydroxyl naphthalene suggested its high efficiency toward intersystem crossing and singlet oxygen generation. Detailed electrochemical investigations suggested the redox activity of the system. Hence, this system represents multifunctional features and can be applied as a functional material for various applications.

Abstract
Photothermal nanomedicine based on self-assembly of biological components, with excellent biosafety and customized performance, is vital significance for precision cancer therapy. However, the programmable design of photothermal nanomedicine remains extremely challenging due to the vulnerability and variability of noncovalent interactions governing supramolecular self-assembly. Herein, it is reported that amino acid encoding is a facile and potent means to design and construct supramolecular photothermal nanodrugs with controlled therapeutic activities. It is found that the amount and type of amino acid dominates the assembled nanostructures, structural stability, energy-conversion pathway, and therapeutic mechanism of the resulting nanodrugs. Two optimized nanodrugs are endowed with robust structural integrity against disassembly along with high photothermal conversion efficiency, efficient cellular internalization, and enhanced tumor accumulation, which result in more efficient tumor ablation. This work demonstrates that design based on amino acid encoding offers an unprecedented opportunity for the construction of remarkable photoactive nanomedicines toward cancer diagnostics and therapeutics.

Int J Biol Macromol 2021; 188:114-125.

Abstract
Herein, a new antioxidant-photosensitizing hydrogel based on chitosan has been developed to control photodynamic therapy (PDT) activity in cancer treatment. In PDT, photosensitizers generate reactive oxygen species (ROS) during photochemical reactions, leading oxidative damage to cancer cells. However, high ROS levels are lethal to non-target healthy cells and tissues such as endothelial cells and blood cells. To mediate these drawbacks, we improved PDT with a natural polyphenolic antioxidant, Tannic acid (TA), to control the ROS level and minimize side effects through singlet oxygen (1O2) scavenging. In this work, chitosan-based hydrogels were designed using tannic acid as an antioxidant cross-linker and loaded with water-soluble N, N'-di-(l-alanine)-3,4,9,10-perylene tetracarboxylic diimide (PDI-Ala) as a photosensitizer. Our results showed that the hydrogel formed a three-dimensional (3D) microstructure with good mechanical strength and significant singlet oxygen production and antioxidant activity. In addition, the behavior of human melanoma cell line A375 and dental pulp stem cells (as normal cells) was compared and studied during an in vitro photodynamic treatment. Normal cells had a higher viability than cancer cells, indicating that the PDT is more effective on cancer cells than on normal cells. The new hydrogels could be applied as an effective new drug to control PDT performance.

Abstract
Chlorophyll, the essential green pigment in plants, is considered a promising natural photosensitizer (PS) for photodynamic therapy (PDT). However, it suffers from lower stability in the physiological conditions that depress its efficacy in the PDT. The combination of nanotechnology and PDT is becoming a promising approach to combat tumors. Gold nanoparticles (Au NPs), for example, are proposed as suitable carriers that can increase chlorophyll stability when conjugating together. In the present work, the impact of Au NPs conjugation in enhancing Chlorophyll b (Chl b) efficiency in the PDT of cancer cells has been emphasized. A chemical method using a natural product synthesized a novel Chlorophyll b-gold nanoparticles nanoconjugate (Chl b-Au NCs). The synthesized Chl b-Au NCs were characterized via UV-Vis spectroscopy, Fourier-transform infrared spectroscopy (FTIR), Laser-Induced Fluorescence (LIF), Zeta potential, Dynamic light scattering (DLS), and Transmission electron microscopy (TEM). Chl b is characterized by a formyl group (CHO) which is absent in Chl a. This group leads to the formation of an electrostatic reaction between the positive charge of Chl b and the negative charge present on the surface of the gold nanoparticles. Moreover, Chlorophyll b loading on the biosynthesized gold nanoparticles (Au NPs) increases its photostability. The efficiency of the PDT was then studied on the MCF7 and the HepG2 cells using this conjugation. As a result, the prepared Chl b-Au NCs showed low dark toxicity, excellent photostability under laser irradiation of wavelength 650 nm, in addition to a significantly high PDT efficacy against tumor cells in vitro. This is due to the enhanced cellular uptake and the high reactive oxygen species (ROS) production upon laser irradiation. Therefore, the designed Chl b-Au NCs could be a photo-therapeutic agent for enhancing cancer therapy in future applications.
