Eco-Friendly Sustainable Nanocarriers to Treat Oxidative Stresses and Skin Aging-Related Ailments, Valorization of a By-Product.

ABSTRACT: The peel from Citrus-sinensis L. is a medicinally significant food waste, and its extract (O-Ext) could be significant against oxidative stresses and skin aging, However, the penetration barriers, instability in formulation, undefined toxicities, and enzymatic activities make the O-Ext difficult to formulate and commercialize. The goal of this study was to evaluate O-Ext against oxidative stress, prepare O-Ext-loaded nano-lipid carriers (O-NLCs), and load them into topical O/W-emulsion (O-NLC-E) to improve O-Ext permeation and its in vivo antiaging effects. TPC, TFC, DPPH activity, and mineral/metal contents of O-Ext were determined via atomic-absorption spectroscopy. For bioactive compounds profiling, GC-MS analysis was carried out. O-NLCs were prepared and tested for physicochemical attributes, while HaCaT and fibroblast cells were used to study permeation and cytotoxicity. The kinetic characteristics of ex vivo permeation through rat skin were established, following the Higuchi model. Following written consent, safety investigations were conducted on human volunteers for three months, where optimized O-NLC-E and B-NLC-E were regularly applied on cheeks. Non-invasive procedures were used to assess the volunteer's skin erythema, TEWL, sebum level, melanin, hydration, pH, elasticity, and pore sizes after specified intervals. The results demonstrated that applying O-NLC-E formulation to the skin of volunteers directed significant antiaging benefits. The study offers nanotechnology-based sustainability approach against skin ageing.

Project description:ObjectivesThe current study aimed to investigate how regulatory frameworks and policies are used to support the use of sustainable medicines within the pharmaceutical sector.MethodsThe Scopus database was searched to retrieve papers. Advanced search tool of the Scopus online database was used focused on the papers that have the search query included in their titles. Data analysis incorporated bibliometric indicators like publication counts and trends, visualized through VOSviewer software version 1.6.20.Key findingsA total of 43 publications on Sustainable Medicines Use were found between 2000 and 2024. Leading countries in publication output on sustainable medicines use were United Kingdom, United States, India, Italy, Portugal, and Switzerland, indicating their collaborative relationships and publication volumes. A total of 92 institutions have been involved in research on Sustainable Medicines Use. Key institutions such as the Faculty of Engineering and the Laboratory for Process and Environmental Engineering, Lowell Center for Sustainable Production, Greiner Environmental Inc., and the University of Florence are prominently featured, indicating their significant contributions to research in this area. Key journals such as the "Journal of Cleaner Production," "Business Strategy and the Environment," "Chemical Engineering Transactions," "Benchmarking," and "Lecture Notes in Mechanical Engineering" are prominently featured. The retrieved articles have been cited an average count of 22.26. The overlay visualization created using VOSviewer suggest a shift towards exploring new drug categories, innovative approaches, and the commercial aspects of sustainability. Future research directions are likely to delve deeper into innovative methods and sustainable chemical practices (green chemistry), reflecting an emphasis on developing greener processes and products.ConclusionThis study offers a thorough analysis of the legislative and governmental strategies promoting the use of sustainable medicine. It offers important insights for promoting sustainability in the pharmaceutical industry by pointing out gaps, defining useful frameworks, and suggesting doable solutions. Achieving sustainable pharmaceutical practices that support worldwide environmental and public health objectives requires sustained research, policy development, and international cooperation. The area needs to keep developing and implementing sustainable methods like green chemistry to decrease environmental harm and improve sustainability. Furthermore, collaborations among academia, industry, and international organizations are essential to progress and interchange effective strategies.

Project description:Malva parviflora L. is an edible and medicinal herb containing mucilaginous cells in its leaves. Mucilage obtained from M. parviflora leaves (MLM) was extracted in distilled water (1:10 w/v) at 70 °C followed by precipitation with alcohol. Preliminary phytochemical tests were performed to assess the purity of the extracted mucilage. Results showed that the yield of mucilage was 7.50%, and it was free from starch, alkaloids, glycosides, saponins, steroids, lipids and heavy metals. MLM had 16.19% carbohydrates, 13.55% proteins and 4.76% amino acids, which indicate its high nutritional value. Physicochemical investigations showed that MLM is neutral and water-soluble, having 5.84% moisture content, 15.60% ash content, 12.33 swelling index, 2.57 g/g water-holding capacity and 2.03 g/g oil-binding capacity. The functional properties, including emulsion capacity, emulsion stability, foaming capacity and stability increased with increased concentrations. Micromeritic properties, such as bulk density, tapped density, Carr's index, Hausner ratio, and angle of repose, were found to be 0.69 g/cm3, 0.84 g/cm3, 17.86%, 1.22 and 28.5, respectively. Scanning electron microscopy (SEM) showed that MLM is an amorphous powder possessing particles of varying size and shape; meanwhile, rheological studies revealed the pseudoplastic behavior of MLM. The thermal transition process of MLM revealed by a differential scanning calorimetry (DSC) thermogram, occurring at a reasonable enthalpy change (∆H), reflects its good thermal stability. The presence of functional groups characteristic of polysaccharides was ascertained by the infrared (IR) and gas chromatography/mass spectrometry (GC/MS) analyses. GC revealed the presence of five neutral monosaccharides; namely, galactose, rhamnose, arabinose, glucose and mannose, showing 51.09, 10.24, 8.90, 1.80 and 0.90 mg/g of MLM, respectively. Meanwhile, galacturonic acid is the only detected acidic monosaccharide, forming 15.06 mg/g of MLM. It showed noticeable antioxidant activity against the DPPH (1,1-diphenyl-2-picrylhydrazyl) radical with an IC50 value of 154.27 µg/mL. It also prevented oxidative damage to DNA caused by the Fenton reagent, as visualized in gel documentation system. The sun protection factor was found to be 10.93 ± 0.15 at 400 µg/mL. Thus, MLM can be used in food, cosmetic and pharmaceutical industry and as a therapeutic agent due to its unique properties.
