The Impact of 2-Ketones Released from Solid Lipid Nanoparticles on Growth Modulation and Antioxidant System of Lactuca sativa. PLANTS (BASEL, SWITZERLAND) 2023; 12:3094. [PMID: 37687341 PMCID: PMC10490278 DOI: 10.3390/plants12173094] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/13/2023] [Revised: 07/31/2023] [Accepted: 08/17/2023] [Indexed: 09/10/2023]
Abstract
2-Ketones are signal molecules reported as plant growth stimulators, but their applications in vegetables have yet to be achieved. Solid lipid nanoparticles (SLNs) emerge as a relevant nanocarrier to develop formulations for the controlled release of 2-ketones. In this sense, seedlings of Lactuca sativa exposed to 125, 375, and 500 µL L-1 of encapsulated 2-nonanone and 2-tridecanone into SLNs were evaluated under controlled conditions. SLNs evidenced a spherical shape with a size of 230 nm. A controlled release of encapsulated doses of 2-nonanone and 2-tridecanone was observed, where a greater release was observed as the encapsulated dose of the compound increased. Root development was strongly stimulated mainly by 2-tridecanone and leaf area (25-32%) by 2-nonanone. Chlorophyll content increased by 15.8% with exposure to 500 µL L-1 of 2-nonanone, and carotenoid concentration was maintained with 2-nonanone. Antioxidant capacity decreased (13-62.7%) in L. sativa treated with 2-ketones, but the total phenol concentration strongly increased in seedlings exposed to some doses of 2-ketones. 2-Tridecanone strongly modulates the enzymatic activities associated with the scavenging of H2O2 at intra- and extracellular levels. In conclusion, 2-ketones released from SLNs modulated the growth and the antioxidant system of L. sativa, depending on the dose released.

Abstract
BACKGROUND The present study was designed to prepare and characterize poly lactide-co-glycolide nanoparticles of antitubercular drugs (ATDs) for delivery through oral route to alveolar macrophages. METHODS Nanoparticles were prepared by double emulsification solvent evaporation method. Ex vivo and in vivo drug accumulation studies were performed in alveolar macrophages, harvested by broncheoalveolar lavaging. Internalization of nanoparticles was studied by confocal laser scanning microscopy. γ-scintigraphy imaging using technetium-99m was done to study the biodistribution pattern of nanoparticles. RESULTS High intracellular concentrations of ATDs were observed in macrophages within 30 min of administration of nanoparticles. Intense radioactivity recorded in liver, spleen and lungs revealed uptake of nanoparticles in macrophages, abundantly present in mononuclear phagocyte system present in these organs. CONCLUSION Targeted delivery of ATDs will help reduce dose and associated side effects including hepatotoxicity of ATDs. Further studies are required to assess the potential therapeutic advantages for treatment of TB.

Abstract
Aim: The purpose of this study was to formulate carbopol hydrogels containing eugenol-loaded solid lipid nanoparticles (EG–SLNs) for epidermal targeting to treat fungal infections in skin. Materials & methods: EG–SLNs were incorporated into carbopol hydrogels and the physiochemical characteristics of EG–SLN in hydrogels were investigated by dynamic light scattering, transmission electron microscopy and atomic force microscopy. Rheological behavior and mechanical properties of hydrogels were also studied before and after incorporation of EG–SLNs. The epidermal-targeting ability of EG–SLN-enriched hydrogels was evaluated by estimation of eugenol in the epidermis of human cadaver skin. An occlusion (hydration) study was also performed to elucidate the mechanism of epidermal targeting of EG–SLN-enriched hydrogels. Results: The particle size (d90) and morphology of EG–SLNs were not significantly changed after incorporation into the hydrogel. EG–SLN of stearic acid-enriched hydrogels follow the Carreau model that describes pseudoplastic flow. The hydrogel containing EG–SLN of stearic acid and of Compritol® (Gattefose, Mumbai, India) showed significantly greater accumulation of eugenol in the epidermis (62.65 ± 4.35 and 52.86 ± 3.76 µg/cm2, respectively) than that of eugenol–hydroxypropyl-β–cyclodextrin complex in hydrogel (9.77 ± 1.16 µg/cm2) and almond oil solution of eugenol (3.45 ± 0.6 µg/cm2). The occlusion study demonstrated greater hydration of human cadaver skin treated with EG–SLN-enriched hydrogel compared with that of hydrogel and intact skin. Conclusion: Hydrogels containing EG–SLNs could be a promising formulation for epidermal targeting to treat fungal infections in skin.

Anti-inflammatory effects and hepatotoxicity of Tripterygium-loaded solid lipid nanoparticles on adjuvant-induced arthritis in rats. PHYTOMEDICINE : INTERNATIONAL JOURNAL OF PHYTOTHERAPY AND PHYTOPHARMACOLOGY 2012; 19:998-1006. [PMID: 22884304 DOI: 10.1016/j.phymed.2012.06.006] [Citation(s) in RCA: 37] [Impact Index Per Article: 3.1] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/22/2011] [Revised: 06/12/2012] [Accepted: 06/17/2012] [Indexed: 06/01/2023]
Abstract
Tripterygium wilfordii Hook f. (TWHF) has been demonstrated to have anti-inflammatory, immunosuppressive effects and its clinical use was restricted to some extent due to some toxic effects on the digestive, urogenital, and blood circulatory systems, especially the male reproductive system. In the previous study, we had confirmed that TWHF-loaded solid lipid nanoparticles (SLN) have protective effects on male reproductive toxicity in rats. Anti-inflammatory effects and hepatotoxicity of TWHF-SLN remain to be unidentified. The present study was focused on the anti-inflammatory effect of complete Freund's adjuvant-induced arthritis in rats treated with TWHF-SLN as well as the effects of SLN delivery system on decreasing the hepatotoxicity induced by tripterygium. Sixty-four healthy male rats were randomly divided into eight groups with eight rats each. From day 18 after FCA injection, TWHF-SLN group (120, 60, 30 mg/kg) and TWHF group (120, 60, 30 mg/kg) were administered by oral gavage for 24 consecutive days. The control group was with saline and model control group was without any treatment. The volume of the right hind paws was evaluated at 0, 4, 8, 12, 18, 24, 30, 36 and 42 days post-injection of FCA by a home-made connected device. The serum alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP), γ-glutamyl transpeptidase (GGT), total bilirubin (TBIL) and albumin (ALB) levels were evaluated by an autoanalyzer. Activities of superoxide dismutase (SOD), glutathione peroxidase (GSH-PX) malondialdehyde (MDA) and xanthine oxidase (XOD) levels were determined using commercial kits. The PG level in sera was examined by double antibody sandwich method. Tissue histopathology was evaluated with hematoxylin and eosin (H&E). The results show that TWHF-SLN can significantly reduce rat paw volume at 60 mg/kg (p<0.05) and PG levels in serum (p<0.05); the levels of ALT, AST, ALP, GGT in serum and MDA, XOD, GSH-PX in liver were not significantly elevated. Histopathology observation found that free TWHF caused more serious damage to the liver than TWHF-SLN. These results revealed that SLN delivery system can enhance the anti-inflammatory activity of TWHF, and meanwhile has a protective effect against TWHF-induced hepatotoxicity.
