[PMID: 38852452 DOI: 10.1016/j.foodchem.2024.139934] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/08/2024] [Revised: 05/19/2024] [Accepted: 05/30/2024] [Indexed: 06/11/2024]
Abstract
Gelatin (GEL), pectin (PEC), carboxymethyl cellulose (CMC), and whey protein isolate (WPI) were employed to formulate hydrogels for stabilizing N-Acetylneuraminic Acid (NeuAc). GEL/WPI-NeuAc hydrogels, irrespective of the ratio, exhibited a flexible and smooth surface with a continuous three-dimensional network structure internally. Porosity of the three types of hydrogels increased from 3.69% to 86.92% (GEL/WPI), 41.67% (PEC/WPI), and 87.62% (CMC/WPI), rendering them suitable as carriers for NeuAc encapsulation. The dynamic swelling behavior of all hydrogels followed Schott's second-order kinetics model. The degradation performance of GEL, PEC, and CMC/WPI-NeuAc hydrogels was optimal at a 5: 5 ratio, with degradation rates of 80.39 ± 1.26%, 82.38 ± 1.96%, and 81.39 ± 1.57%, respectively. GEL, PEC, CMC/WPI-NeuAc hydrogels demonstrated decreased release rates of 44.56%, 31.04%, and 41.26%, respectively, compared to free NeuAc, post gastric digestion. The present investigation suggests the potential of GEL/WPI hydrogels as effective carriers for delivering NeuAc encapsulation.

Assessment of the anti-cancer potential of Ephedra foeminea leaf extract on MDA-MB-231, MCF-7, 4 T1, and MCF-10 breast cancer cell lines: Cytotoxic, apoptotic and oxidative assays. Saudi Pharm J 2024; 32:101960. [PMID: 38328794 PMCID: PMC10847678 DOI: 10.1016/j.jsps.2024.101960] [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: 07/15/2023] [Accepted: 01/17/2024] [Indexed: 02/09/2024] Open
Abstract
Ephedra foeminea is traditionally used to treat breast cancer in several Arab countries. Scientific studies have reported different effects of this plant on some cancer cell lines. The current study determined the anti-cancer potential of the methanolic extract of Ephedra foeminea against four different types of breast cancer cell lines in-vitro. The extract was prepared by maceration and phytoconstituents were identified by LC-MS analysis. The IC50 value was determined against MDA-MB-231, MCF-7, 4 T1, and MCF-10 cell lines using the MTT assay. Further investigations were carried out using IC50 concentration of the extract (40.09 µg/ml) to determine live/dead cells by acridine orange/ethidium bromide staining. The effect on the expression of reactive oxygen species (ROS) was evaluated by flow cytometry. The results were analyzed using one-way ANOVA followed by Tukey's test. The LC-MS analysis revealed the presence of 34 and 30 phytoconstituents in positive and negative modes respectively. The Ephedra foeminea extract was most effective against 4 T1 cells in a dose-dependent manner (P < 0.001) with an IC50 value of 40.09 µg/ml and showed negligible effect against MCF-10 cells. It increased apoptosis in 77.84 % of 4 T1 cells, as determined by acridine orange/ethidium bromide staining. The extract also increased the ROS expression in the 39.57 % of 4 T1 cells. The study results showed that Ephedra foeminea extract possesses an anti-cancer effect against 4 T1 cells by increasing the expression of ROS and inducing apoptosis in the 4 T1 cells. The result suggests Ephedra foemenia methanolic extract possesses a reasonable anti-cancer effect due to its effect on apoptosis and oxidative pathways. The results confirm the traditional belief that Ephedra is effective against breast cancerز.

Abstract
Most supramolecular systems were discovered by using a trial-and-error approach, leading to numerous synthetic efforts to obtain optimal supramolecular building blocks for selective guest encapsulation. Here, we report a simple coassembly strategy for preparing tamoxifen-selective supramolecular nanomaterials in an aqueous solution. The synthetic amphiphile molecule, 1,1,2,2-tetraphenylethylene (TPE), promotes large tamoxifen aggregate disassembly into smaller, discrete aggregates such as ribbon-like and micellar assemblies in coassembled solutions, enhancing the solubility and dispersion. The TPE moiety exhibits enhanced emission upon tamoxifen interaction, enabling the observation of the coassembled species in an aqueous solution for cell imaging. The tamoxifen-selective fluorescent micelles in the presence of a 1:1 molar ratio of TPE derivative with tamoxifen show enhanced tamoxifen absorption and anticancer effects against MCF-7 breast cancer cells. These supramolecular approaches, based on the coassembly of building blocks with molecular structural similarity, can provide a novel strategy for the efficient development of selective molecular carriers with enhanced biological activities.

Talanta 2024; 266:124969. [PMID: 37524040 DOI: 10.1016/j.talanta.2023.124969] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/26/2023] [Revised: 07/08/2023] [Accepted: 07/18/2023] [Indexed: 08/02/2023]
Abstract
Studies have shown that hypobromous acid (HOBr) produced during chlorination disinfection of tap water can react with some organic matter in water to form toxic brominated disinfection byproducts (Br-DBPs) and HOBr also plays an important role during the process of micro pollutants degradation. Hence, real-time monitoring of HOBr in water environment plays a significant role in controlling the generation of Br-DBPs and degradation of micro pollutants. Herein, a novel highly specific fluorescent probe (PBE-HOBr) for accurate detection of HOBr was constructed based on the HOBr-induced oxidation elimination of benzothiazoline moiety employing the photo-induced electron transfer (PET) mechanism. PBE-HOBr has high sensitivity and linear response to HOBr with a low detection limit of 119 nM. PBE-HOBr not only has the ability to detect endogenous and exogenous HOBr in cells and zebrafish, but also has been used to monitor the formation of HOBr in water treatment. In addition, benzothiazoline group was demonstrated for the first time to be able to be used as a new recognition receptor for developing highly specific fluorescent probes for HOBr.

Front Nutr 2023; 10:1181942. [PMID: 37275652 PMCID: PMC10235517 DOI: 10.3389/fnut.2023.1181942] [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: 03/08/2023] [Accepted: 04/18/2023] [Indexed: 06/07/2023] Open
Abstract
Platostoma palustre (or Mesona chinensis Benth) is an important medicinal and edible plant in China and Southeast Asian countries. To study the effects of different processing methods on the quality, nutrition, and flavor of P. palustre, we adopted the LC-MS and HS-GC-MS to compare the influences of tedding (S), sweating (M), and drying (H) on the metabolites and volatile substances of P. palustre. Biochemical determinations revealed that the M treatment could promote the accumulation of the contents of total sugar, soluble sugar, and total pectin compared with the H and S treatments but decrease the total flavonoid contents. LC-MS and HS-GC-MS uncovered 98 differential metabolites and 27 differential volatile substances among the three treatments, respectively. Overall, the M treatment facilitated the stabilization and improvement of the quality of polysaccharides and volatile substances, while the H treatment could promote the level of amino acids in P. palustre. The current study provided a theoretical reference for establishing standardized processing methods and sustaining the quality stability of P. palustre in future.
