Life (Basel) 2024; 14:144. [PMID: 38276273 DOI: 10.3390/life14010144] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/11/2023] [Revised: 12/22/2023] [Accepted: 01/02/2024] [Indexed: 01/27/2024] Open
Abstract
The excessive use of synthetic pesticides has detrimental impacts on humans, non-target organisms, and the environment. Insect pest management strategies are shifting toward biopesticides, which can provide a feasible and environmentally friendly green solution to the pest problem. The key objective of the present research work was the preparation of Mentha piperita-based nanobiopesticides with enhanced stability, solubility, and pesticidal potential. Nanobiopesticides based on the Mentha piperita extract were prepared using the antisolvent precipitation method. The central composite design of response surface methodology (RSM) was utilized to optimize different process parameters, e.g., the amounts of the stabilizer and plant extract. The nanosuspension of Mentha piperita prepared with the stabilizer SLS showed a particle size of 259 nm and a polydispersity index of 0.61. The formulated biopesticides in the form of nanosuspensions showed good antibacterial activities as compared to the Mentha piperita extract against two phytopathogenic bacterial strains, Clavibacter michiganensis and Pseudomonas syringae. The M. piperita nanosuspension had higher antifungal efficacy against A. niger and F. oxysporum than the Mentha piperita extract. The M. piperita extract and its nanosuspensions were tested for pesticidal activity against the stored-grain insects Tribolium castaneum and Sitophilus oryzae. Mentha piperita-based nanobiopesticides demonstrated significantly high (p < 0.05) average mortality of 84.4% and 77.7% against Tribolium castaneum and Sitophilus oryzae, respectively. Mentha piperita-based nanobiopesticides showed enhanced pesticidal potential and could be used as a good alternative to synthetic chemical pesticides.

Gamma oryzanol loaded into micelle-core/chitosan-shell: from translational nephroprotective potential to emphasis on sirtuin-1 associated machineries. Int J Pharm 2023; 631:122482. [PMID: 36513255 DOI: 10.1016/j.ijpharm.2022.122482] [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: 08/29/2022] [Revised: 12/02/2022] [Accepted: 12/06/2022] [Indexed: 12/14/2022]
Abstract
Gamma oryzanol (ORZ) is a nutraceutical that is poorly water soluble with poor intestinal absorption. In the current work, ORZ was nanoformulated into uncoated and chitosan coated micelles based on methoxy-poly(ethylene glycol)-b-poly(ε-caprolactone) (mPEG-PCL) and poly(ε-caprolactone)-b-methoxy-poly(ethylene glycol)-b-poly(ε-caprolactone) (PCL-PEG-PCL) copolymers for augmenting ORZ oral delivery. The physicochemical properties, morphological study, in-vitro release and safety of the nanoplaforms were determined. Importantly, the nephroprotective competence of the nanoplaforms was analyzed against acute kidney injury (AKI) rat model and the sirtuin-1 associated machineries were assessed. The results revealed that the micelles exerted particle size (PS) from 97.9 to 117.8 nm that was markedly increased after chitosan coating. The reversal of zeta potential from negative to highly positive further confirmed efficient coating. In vitro release profiles demonstrated prolonged release pattern. The nanoforms conferred higher cell viability values than free ORZ on Vero cell line. The designed micelles displayed augmented nephroprotection compared to free ORZ with the supremacy of CS coated micelles over uncoated ones in restoring kidney parameters to normal levels. The attenuated AKI was fulfilled via the modulation of sirtuin-1 signaling pathways translated by restoring the histological features, increasing renal antioxidant states, renal autophagy and decreasing renal inflammation and renal apoptosis. These outcomes confirmed that surface modification with chitosan had a considerable leverage on micelles safety, release behavior and in vivo performance.

Abstract
The objective of this study was to develop ritonavir (RTV) nanosuspensions (NSs) by microfluidization method. Particle size (PS) measurements were performed by photon correlation spectroscopy. Amorphous properties of the particles were evaluated by X-ray diffraction (XRD) and scanning electron microscopy (SEM). The dissolution studies were conducted in fed state simulated intestinal fluid (FeSSIF) medium. The flow cytometry was utilized to determine the lymphocyte sub-groups and immune response of NSs. RTV NSs were obtained with 400-500 nm PS. The crystal properties of RTV remain unchanged. The solubility of NS was enhanced five times. 57% and 18% of RTV were dissolved in FeSSIF medium for NSs and coarse powder. According to immunological studies, the prepared NSs did not significantly alter the ratio of CD4+/CD8+. Therefore, NSs may be a beneficial approach for the oral administration of RTV.

Electrostatic molecular effect of differently charged surfactants on the solubilization capacity and physicochemical properties of salt-caged nanosuspensions containing pH-dependent and poorly water-soluble rebamipide. Int J Pharm 2022; 619:121686. [PMID: 35314274 DOI: 10.1016/j.ijpharm.2022.121686] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/19/2021] [Revised: 02/09/2022] [Accepted: 03/15/2022] [Indexed: 11/15/2022]
Abstract
In this study, the electrostatic molecular effect of differently charged surfactants on the solubilization capacity and physicochemical properties of salt-caged nanosuspensions (NSPs) containing poorly water-soluble drug was investigated. Anionic rebamipide (RBM) was chosen as a model drug because of its poor water solubility in low pH condition and ionizable acidic forms. Negatively charged sodium lauryl sulfate (SLS) and positively charged cetyltrimethylammonium bromide (CTAB) were selected as surfactants for the preparation of NSPs or in the dissolution medium. Salt-caged NSPs surrounded by NaCl were prepared by the HCl-NaOH neutralization method in the presence of poloxamer 407. Interestingly, the addition of positively charged CTAB in the preparation process or the dissolution media could interfere with the solubilization capacity of salt-caged NSPs containing a negatively charged drug via intermolecular electrostatic attraction. In the presence of positively charged CTAB, the salt-caged NSP was disordered in structure via electrostatic attractive interaction with partially ionizable anionic RBM resulting in changes in the physicochemical properties of the salt-caged NSP such as low drug content, increased particle size, decreased dissolution rate, and the formation of water-insoluble precipitates with rough and irregular crystals. This inhibitory effect of CTAB on the dissolution rate of pure RBM and the salt-caged NSP in pH 6.8 intestinal fluid was pronounced in a concentration-dependent manner mainly owing to the formation of precipitates, so-called poorly soluble complexes. When the salt-caged NSP (F1) was dissolved in DW containing CTAB, the dissolution rate decreased more significantly, dissolving less than 20% within 2 h. Depending on the surfactant charges, the charge density and the initial potential were varied during the dissolution of NSPs in deionized water (DW). In contrast, the negatively charged SLS did not significantly change the physicochemical properties of the salt-caged NSP. For example, the dissolution rate of the salt-caged NSP containing SLS in DW or pH 1.2 gastric fluid remained over 90% for 2 h. Surfactants for the formulation or dissolution media should be chosen carefully because of their effect on the physicochemical properties and solubilization capacity of salt-caged NSPs containing poorly water-soluble and ionizable drugs via electrostatic molecular interactions.
