[PMID: 38729731 DOI: 10.1016/j.foodres.2024.114374] [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: 01/07/2024] [Revised: 04/08/2024] [Accepted: 04/17/2024] [Indexed: 05/12/2024]
Abstract
As a crucial component of the fungal cell membranes, ergosterol has been demonstrated to possess surface activity attributed to its hydrophobic region and polar group. However, further investigation is required to explore its emulsification behavior upon migration to the oil-water interface. Therefore, this study was conducted to analyze the interface properties of ergosterol as a stabilizer for water in oil (W/O) emulsion. Moreover, the emulsion prepared under the optimal conditions was utilized to load the water-soluble bioactive substance with the chlorogenic acid as the model molecules. Our results showed that the contact angle of ergosterol was 117.017°, and its dynamic interfacial tension was obviously lower than that of a pure water-oil system. When the ratio of water to oil was 4: 6, and the content of ergosterol was 3.5 % (ergosterol/oil phase, w/w), the W/O emulsion had smaller particle size (438 nm), higher apparent viscosity, and better stability. Meanwhile, the stability of loaded chlorogenic acid was improved under unfavorable conditions (pH 1.2, 90 °C, ultraviolet irradiation, and oxidation), which were 73.87 %, 59.53 %, 62.53 %, and 69.73 %, respectively. Additionally, the bioaccessibility of chlorogenic acid (38.75 %) and ergosterol (33.69 %), and the scavenging rates of the emulsion on DPPH radicals (81.00 %) and hydroxyl radicals (82.30 %) were also enhanced. Therefore, a novel W/O Pickering emulsion was prepared in this work using ergosterol as an emulsifier solely, which has great potential for application in oil-based food and nutraceutical formulations.

Abstract
Ergosterol is an important sterol commonly found in edible mushrooms, and it has important nutritional value and pharmacological activity. Ergosterol is a provitamin. It has been well established that edible mushrooms are an excellent food source of vitamin D2 because ergosterol is a precursor that is converted to vitamin D2 under ultraviolet radiation. The pharmacological effects of ergosterol, which include antimicrobial, antioxidant, antimicrobial, anticancer, antidiabetic, anti-neurodegenerative, and other activities, have also been reported. This review aims to provide an overview of the available evidence regarding the pharmacological effects of ergosterol and its underlying mechanisms of action. Their potential benefits and applications are also discussed.

Abstract
Mushrooms are known not only for their taste but also for beneficial effects on health attributed to plethora of constituents. All mushrooms belong to the kingdom of fungi, which also includes yeasts and molds. Each year, hundreds of new metabolites of the main fungal sterol, ergosterol, are isolated from fungal sources. As a rule, further testing is carried out for their biological effects, and many of the isolated compounds exhibit one or another activity. This study aims to review recent literature (mainly over the past 10 years, selected older works are discussed for consistency purposes) on the structures and bioactivities of fungal metabolites of ergosterol. The review is not exhaustive in its coverage of structures found in fungi. Rather, it focuses solely on discussing compounds that have shown some biological activity with potential pharmacological utility.

Abstract
![]()
The triterpenoid
natural products have played an important role
in understanding mechanistic models of human diseases. These natural
products are diverse, but many have been characterized as reactive
oxygen species (ROS) modulators. ROS can regulate cell survival and
function, which ultimately affects biological processes leading to
disease. The triterpenoids offer an untapped source of creativity
to generate tool compounds with high selectivity to regulate ROS.
This brief Review highlights the diverse complexity by which these
secondary metabolites induce many cell death modalities (apoptosis,
autophagy, ferroptosis, etc.) that can affect various complex cell
signaling pathways through ROS and ultimately lead to evading or accelerating
cell death.

Abstract
The therapeutic arsenal for the treatment of leishmaniasis is limited and has serious obstacles, such as variable activity, high toxicity, and costs. To overcome such limitations, it becomes urgent to characterize new bioactive molecules. Plants produce and accumulate different classes of bioactive compounds, and these molecules can be studied as a strategy to combat leishmaniasis. The study presented herein evaluated the leishmanicidal effect of maslinic acid isolated from the leaves of Hyptidendron canum (Lamiaceae) and investigated the morphological that occurred on Leishmania (Leishmania) infantum upon treatment. Maslinic acid was active and selective against promastigote and amastigote forms in a dose-dependent manner. Additionally, it was not toxic to peritoneal macrophages isolated from golden hamsters, while miltefosine and amphotericin B showed mild toxicity for macrophages. Morphological changes in promastigotes of L. (L.) infantum treated with maslinic acid were related to cytoplasmic degeneration, intense exocytic activity, and blebbing in the kDNA; disruption of mitochondrial cristae was observed in some parasites. The nucleus of promastigote forms seems to be degraded and the chromatin fragmented, suggesting that maslinic acid triggers programmed cell death. These results indicate that maslinic acid may be an interesting molecule to develop new classes of drugs against leishmaniasis.

Abstract
Abstract
Objectives
Sorafenib (SOR) is an orally administered molecular targeted agent in the systemic chemotherapy of hepatocellular carcinoma (HCC). However, the partial response of SOR is limited due to its adverse side effect and high heterogeneity and resistant phenotype of HCC. In the current study, we investigated synergistic effects of SOR and usnic acid (UA) on HCC cell lines including HepG2 and SNU-449, and a normal cell line, HUVEC.
Methods
The antiproliferative and apoptotic effects of combination therapy and SOR alone were analysed by WST-1 and Annexin V analysis, respectively. Furthermore, cell cycle, gene expression analysis of SOR-targeted kinases and acridine orange–ethidium bromide staining were also performed in combined treatments.
Key findings
Our results demonstrated that SOR and UA combination indicated a strong synergism in HCC cell lines and reduced SOR toxicity in HUVEC cells. Additionally, the combination treatment SOR and UA significantly induced much more apoptotic cell death and G0/G1 arrest through downregulation of SOR-targeted kinases.
Conclusions
Consequently, SOR and UA combination could be a new therapeutic strategy for HCC treatment.

Antilung cancer effect of ergosterol and cisplatin-loaded liposomes modified with cyclic arginine-glycine-aspartic acid and octa-arginine peptides. Medicine (Baltimore) 2018; 97:e11916.

Abstract
BACKGROUND Lung cancer is one of the most important diseases threatening human health, and targeted therapy has become the main research direction. This work, therefore, aimed to develop cyclic arginine-glycine-aspartic (RGD) and octa-arginine (R8) peptide-modified ergosterol (ERG)-combined cisplatin (diamminedichloridoplatinum(II) [DDP]) liposomes (LIP) as a drug delivery system. METHODS Soybean phospholipids (SPC) and cholesterol (Chol) were selected to prepare different LIPs: ERG-loaded LIP (ERG-LIP), DDP and ERG-LIP (DDP/ERG-LIP), R8 peptide-modified DDP and ERG-LIP (R8-DDP/ERG-LIP), and cyclic RGD and R8-DDP/ERG-LIP (RGD/R8-DDP/ERG-LIP). The quality, tumor sphere penetrating ability, in vitro cellular uptake, mechanism of cellular uptake, and in vitro cytotoxicity of RGD/R8-DDP/ERG-LIP were evaluated. RESULTS The LIP quality evaluation revealed that RGD/R8-DDP/ERG-LIP is round with a double-layer structure. The average particle size, dispersion coefficient of the polydispersity index (PDI), and zeta potential of RGD/R8-DDP/ERG-LIP were 155.2 ± 8.7 nm, 0.102, and 4.74 ± 0.7 mV, respectively. Furthermore, the LIPs were stable in the serum, and obviously inhibited the growth of A549 lung cancer cells with RGD/R8-DDP/ERG-LIP exhibiting the strongest inhibitory effect. The highest cellular uptake rate, which was at 4 hours, was exhibited by RGD/R8-DDP/ERG-LIP in a concentration-dependent manner. CONCLUSION The results showed that LIP uptake by A549 cells was mainly by the clathrin-mediated endocytosis pathway (chlorpromazine). The results also suggest that RGD/R8-DDP/ERG-LIP might be a promising drug delivery system to improve antilung cancer drug effect and tumor-targeting in vitro.
