Augmented antiviral activity of chlorhexidine gluconate on herpes simplex virus type 1, H1N1 influenza A virus, and adenovirus in combination with salicylic acid. Arch Virol 2023; 168:302. [PMID: 38036721 DOI: 10.1007/s00705-023-05932-1] [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: 02/25/2023] [Accepted: 09/18/2023] [Indexed: 12/02/2023]
Abstract
BACKGROUND The excessive usage of chlorhexidine gluconate (CHG) as a broad-spectrum antimicrobial reagent can have a negative impact on the environment and on human health. The aim of this study was to investigate the effectiveness of some plant-derived compounds in reducing the CHG concentration required to exert its antiviral activity. METHODS Antiviral assays were conducted according to EN 14476 (2019) against herpes simplex virus type 1 (HSV-1), H1N1 influenza A virus, and adenovirus type 5 (Ad-5) as enveloped and non-enveloped viral models to assess the synergistic interaction of CHG and natural additive compounds. RESULTS The effective concentration of 0.247 mM CHG against HSV-1 was decreased tenfold in combination with 0.0125 mM salicylic acid, with a titer reduction of 1.47 ⋅ 104 CCID50/ml. The time required for complete inactivation of HSV-1 particles was reduced to 15 min when the virus was exposed to 0.061 mM CHG and 0.0125 mM salicylic acid. Additionally, the presence of salicylic acid protected the CHG activity against interfering substances. CONCLUSION Our supplemented CHG formulation showed immediate antiviral effectiveness, which is important for management of the infections. CHG can be combined with salicylic acid to exhibit synergistic antiviral activity at lower concentrations and reduce the time required for inactivation. Furthermore, in the presence of interfering substances, the combination has higher antiviral activity than CHG alone.

Abstract
Professor Bruce Ames demonstrated that nutritional recommendations should be adjusted in order to 'tune-up' metabolism and reduce mitochondria decay, a hallmark of aging and many disease processes. A major subset of tunable nutrients are the minerals, which despite being integral to every aspect of metabolism are often deficient in the typical Western diet. Mitochondria are particularly rich in minerals, where they function as essential cofactors for mitochondrial physiology and overall cellular health. Yet substantial knowledge gaps remain in our understanding of the form and function of these minerals needed for metabolic harmony. Some of the minerals have known activities in the mitochondria but with incomplete regulatory detail, whereas other minerals have no established mitochondrial function at all. A comprehensive metallome of the mitochondria is needed to fully understand the patterns and relationships of minerals within metabolic processes and cellular development. This brief overview serves to highlight the current progress towards understanding mineral homeostasis in the mitochondria and to encourage more research activity in key areas. Future work may likely reveal that adjusting the amounts of specific nutritional minerals has longevity benefits for human health.

Abstract
Various kind of organics are toxic and detrimental, resulting in eutrophication, black, odorous water and so on. Photocatalysis has been deemed to be a promising technology which can decompose different kinds of organic pollutants under visible light irradiation, finally achieving non-poisonous, harmless CO2, water and other inorganic materials. Bismuth oxychloride (BiOCl) is considered as a promising photocatalyst for the efficient degradation of organic pollutants due to its high chemical stability, unique layered structure, resistance to corrosion and favorable photocatalytic property. However, BiOCl can only absorb UV irradiation because of its wide band gap of 3.2 eV-3.5 eV that limits its photocatalytic performance. Herein, a lot of methods have been reviewed to improve its photocatalytic activity. We introduced the unique and special layered structure of BiOCl, the typical and common synthesis methods that can control the morphology, and the most important part is varies of modification routes of BiOCl and the application of BiOCl-based materials for photocatalytic degradation of organic pollutants. Besides, we summarized the crucial issues and perspectives about the application of BiOCl in pollution management.

Abstract
Here, bismuth-based nanomaterials (Bi-based NMs) are introduced as promising theranostic agents to enhance image contrast as well as for the therapeutic gain for numerous diseases. However, understanding the interaction of such novel developed nanoparticles (NPs) within a biological environment is a requisite for the translation of any promising agent from the lab bench to the clinic. This interaction delineates the fate of NPs after circulation in the body. In an ideal setting, a nano-based therapeutic agent should be eliminated via the renal clearance pathway, meanwhile it should have specific targeting to a diseased organ to reach an effective dose and also to overcome off-targeting. Due to their clearance pathway, biodistribution patterns and pharmacokinetics (PK), Bi-based NMs have been found to play a determinative role to pass clinical approval and they have been investigated extensively in vivo to date. In this review, we expansively discuss the possible toxicity induced by Bi-based NMs on cells or organs, as well as biodistribution profiles, PK and the clearance pathways in animal models. A low cytotoxicity of Bi-based NMs has been found in vitro and in vivo, and along with their long-term biodistribution and proper renal clearance in animal models, the translation of Bi-based NMs to the clinic as a useful novel theranostic agent is promising to improve numerous medical applications.

Abstract
Peracetic acid (PAA) has been used to sterilize biomaterial scaffolds and allografts before their implantation. Although the antimicrobial effectiveness of PAA is widely known, there are no studies investigating its cytotoxicity on keratinocytes. This study aimed to investigate the cytotoxicity of PAA concentrations on keratinocytes by growing HaCaT cells in culture medium. Different concentrations of PAA (control-untreated, 0.01, 0.1, 1, 10, 100, 200, 400, 800, 1200, 1600, and 2000 ppm) were added to the culture wells and allowed to be in direct contact with cells for up to 24 hours. Cytotoxicity was quantitatively and qualitatively determined by cell viability assay and analysis of morphological changes. Statistical analysis was performed with 1-way analysis of variance and Tukey test at 5% significance. Cells treated with 0.01 and 0.1 ppm followed the same morphological pattern of untreated cells, whereas cells treated with 1.0 ppm presented about 20% of floating cells and dark cytoplasmic granules. More than 50% of the cells treated with 10 and 100 ppm were destroyed, whereas the attached ones showed unclear and interrupted cell membranes. Concentrations of 1 ppm or greater had less than 64.4% of viable cells compared with the control group. This study concluded that exposure of keratinocytes to concentrations of 1 ppm or greater of PAA resulted in strong cytotoxic effects.

Abstract
Metal nanoparticles or metal-based compounds have drawn attention in various fields ranging from industry to medicine because of their unique physicochemical properties. Bismuth (Bi) compounds and nanomaterials have been commonly used in alloys, electronic industry, batteries, and as flame retardants as well as for anti- Helicobacter pylori therapy, while the nanomaterial form has great potential for computed tomography imaging and thermotherapy, both of which will be introduced in this review. Although Bi was used for several decades, there is a lack of detailed information concerning their toxicity and mechanisms on human health. We described the toxicity of Bi on the kidney that seemed to be relatively known by researchers, while the mechanisms remain unclear. Recently, our group has found that Bi compounds, including bismuth nitrate (BN) and Bi nanomaterials, can induce autophagy in kidney cells. We also extended our findings by selecting five Bi compounds, and the results showed that BN, bismuth oxychloride, bismuth citrate, colloidal bismuth subcitrate, and Bi nanomaterials all induced slight cytotoxicity accompanied with autophagy. Although the role of autophagy in Bi-induced cytotoxicity and kidney injury is under investigation by us, autophagy may help with the exploration of the mechanisms of nephrotoxicity by Bi.

Abstract
Ionic liquids have gained increasing attention in the chemical industry as potential green substitutes for traditional solvents. However, little is known about toxicity of ionic liquids on the skin, a major exposure portal to toxic substances. Here, we evaluated dermal toxicity of ionic liquids using human keratinocyte and fibroblast cell line, 3D reconstructed human epidermis, and full-thickness model to investigate underlying mechanisms. Cytotoxicity of ionic liquids was evaluated for representative anions, [TFSI], [PF6], [BF4], and [DCA], as well as for cations, [EMIM], [BMPY], [TBA] and [Zn], in human keratinocyte cell line, HaCaT, and human dermal fibroblasts. In our results, significant cytotoxicity was induced by ionic liquids with [TFSI] in both cell lines. Notably, cytotoxicity of [TFSI] containing ionic liquids was comparable to xylene, a toxic conventional organic solvent. Fluorescent and flow cytometric analysis revealed that [TFSI]-exposed cells underwent necrotic cell death. Reactive oxygen species (ROS) was increased while the amount of glutathione was decreased by [TFSI] in dose-dependent manner, which was reversed by antioxidant, N-acetylcysteine. In 3D reconstructed human epidermis and full-thickness model, a single application of [TFSI] induced toxicity although it was minimal and largely limited to epidermal layer. Collectively, these results demonstrated potential dermal toxicity of ionic liquids.

Abstract
Recently, bismuth oxychloride nanomaterials (BiOCls) are showing great promise in pollutant removal. Residues from these environmental remediations are potential hazardous materials. Unfortunately, human health risks of BiOCls are still unexplored widely. In the present study, we focused on the influence of physicochemical properties on the cytotoxicity of BiOCls toward a human skin derived cell line (HaCaT). Results showed that morphology and surface hydroxyl both had a profound effect on the toxicity of BiOCls. Microsphere-shaped BiOCl caused less toxicity than nanosheet-shaped BiOCl because of weaker particle-membrane interactions, while the presence of surface hydroxyl on microsphere-shaped BiOCl significantly raised the toxicity owing to the increased interaction with cell membrane. Both microsphere-shaped BiOCl with surface hydroxyl and nanosheet-shaped BiOCl caused significant cell membrane damage (PI uptake and LDH release), however, based on the different mechanism. The former may be a predominant "chemical" mechanism involved an oxidative stress paradigm, as manifested by elevated ROS and depleted GSH, while the latter is mainly due to a direct "physical" damage to cell membrane. Both "physical" and "chemical" response led to cell death. Furthermore, a set of experiments including MMP collapse, cell cycle arrest, and apoptosis/necrosis were conducted to propose a scenario for toxicological aspects of BiOCls. Data presented here would help to enable the rational design of BiOCls for either reducing their unintended consequences or increasing their application potentials.

Abstract
Ethyl carbamate (EC) is a multi-site carcinogen in experiment animals and probably carcinogenic to humans (IARC group 2A). The present study was designed to investigate the cytotoxicity effect of EC on human hepatoma G2 (HepG2) cells. The results revealed that EC inhibited the viability of HepG2 cells significantly in a dose-dependent manner. Further analysis indicated that high concentration of EC induced cell apoptosis, inhibited the G1 to S phase transition along with increased expression of p53 and p21 and decreased the expression of cyclin E and Cdk 2, but no significant change in p27 expression was observed, which were evidenced by both real time PCR and western blotting analyses. Moreover, the results of the DCFH-DA assay suggested that oxidative stress was involved in the cytotoxic effects of EC. Altogether, the present work indicated that p21, cyclin E and Cdk2, which were regulated by p53, might account for the effect of EC on cell viability and cell cycle arrest, but p27 was not involved in the pathway in HepG2 cells treated with EC.
