[PMID: 37560710 PMCID: PMC10407673 DOI: 10.1016/j.heliyon.2023.e18153] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/23/2023] [Revised: 07/09/2023] [Accepted: 07/10/2023] [Indexed: 08/11/2023] Open
Abstract
Nanostructured metal oxide particles with diversified morphologies are in high demand in nanotechnology. The particle size, shape, and overall geometry mainly depend on the fabrication method. This study reports synthesis of zinc oxide nanoparticles (ZnO NPs) from zinc nitrate hexahydrate [Zn(NO3)2.6H2O] precursor in aqueous media at 65 °C by using lactose from cow milk as a reducing agent and regulating pH from 6 to 10. UV-visible absorption gave maximum absorbance (λmax) at 371-375 nm in ethanol for localized surface plasmon resonance (LSPR), FTIR exhibited bands at ca. 439-481 cm-1 for stretching mode Zn-O bonds, and XRD peaks at 2 θ values at 31.8, 34.45, and 36.28° confirmed the fabricated ZnO NPs. The XRD spectra also indicated that the ZnO crystallite (20-30 nm) has a hexagonal wurtzite structure. The average particle sizes measured by DLS were ca. 50-837 nm, and SEM microphotographs demonstrated the morphology of ZnO NPs with a hexagonal, rod-shaped, or spike-like structure. The ZnO NPs were used to investigate the LSPR absorption at various concentrations of insulin, ranging from 2.5 μM to 50 μM. The ZnO NPs fabricated at pH 7 and 10 showed better insulin sensing performance with high precision. The synthesis approach of ZnO NPs with variable morphologies would play a significant function in biomedical science especially real time monitoring of glucose for efficient management of diabetes.

Abstract
Background:
Monoclonal antibodies licensed by the US Food and Drug Administration
(FDA) target diverse biological targets relevant to immuno-oncology, and small compounds in clinical
trials target various aspects of immuno-oncology. Several small compounds that target CD73 are
at various stages of clinical studies. Several imidazoles are currently being utilized to treat malignancies,
including Dacarbazine, Zoledronic acid, Mercaptopurine, and others. As a result, we evaluated
the cytotoxicity of modified tri-phenyl imidazoles against breast cancer cell lines, as well as conducted
virtual tests.
Methods:
We used Accelrys Drug Discovery Studio 3.5 software to undertake molecular docking,
ADMET, and molecular properties studies on 68 proposed imidazole derivatives. The synthesized
compounds' binding mechanisms were investigated against the CD73 protein (PDB Code: 4H1S).
To find the drugs with the best pharmacokinetics, researchers assessed ADMET solubility, BBB
penetration, hepatotoxicity, PPB binding, and polar surface area. The MDA-MB-231 breast cancer
cell line was treated with these produced compounds, and the MTT test method was used to determine
the IC50 values.
Results:
The selected 14 compounds showed good binding in the active site of CD73 by forming Hbonds
with amino acid residues, according to molecular docking studies. Breast cancer cell lines
were treated with substituted tri-phenyl imidazole derivatives, which displayed anticancer activity.
Compounds 3a and 3h, which had an electron-donating group at the 2nd and 3rd positions and
p-substitutions of the chloro and nitro groups, respectively, showed considerable anticancer action.
Conclusion:
Fourteen imidazole derivatives were produced and tested against breast cancer cell
lines based on in-silico research. The MDA-MB-231 cell line was strongly suppressed by compounds
3a and 3h. In-vitro enzyme inhibition experiments revealed that only 3h demonstrated considerable
inhibition.

Front Microbiol 2020; 11:365.

Abstract
Engineered nanoparticles have provided a basis for innovative agricultural applications, specifically in plant disease management. In this interdisciplinary study, by conducting comparison studies using macroscale magnesium oxide (mMgO), we evaluated the fungicidal activity of MgO nanoparticles (nMgO) against soilborne Phytophthora nicotianae and Thielaviopsis basicola for the first time under laboratory and greenhouse conditions. In vitro studies revealed that nMgO could inhibit fungal growth and spore germination and impede sporangium development more efficiently than could macroscale equivalents. Indispensably, direct contact interactions between nanoparticles and fungal cells or nanoparticle adsorption thereof were found, subsequently provoking cell morphological changes by scanning electron microscopy/energy-dispersive spectrometry (SEM/EDS) and transmission electron microscopy (TEM). In addition, the disturbance of the zeta potential and accumulation of various modes of oxidative stress in nMgO-exposed fungal cells accounted for the underlying antifungal mechanism. In the greenhouse, approximately 36.58 and 42.35% decreases in tobacco black shank and black root rot disease, respectively, could testify to the efficiency by which 500 μg/ml of nMgO suppressed fungal invasion through root irrigation (the final control efficiency reached 50.20 and 62.10%, respectively) when compared with that of untreated controls or mMgO. This study will extend our understanding of nanoparticles potentially being adopted as an effective strategy for preventing diversified fungal infections in agricultural fields.

BIOMED RESEARCH INTERNATIONAL 2017; 2017:2105610. [PMID: 29312992 PMCID: PMC5664374 DOI: 10.1155/2017/2105610] [Citation(s) in RCA: 17] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 05/11/2017] [Revised: 07/31/2017] [Accepted: 08/27/2017] [Indexed: 01/04/2023]
Abstract
Breast cancer is one of the leading causes of death noticed in women across the world. Of late the most successful treatments rendered are the use of aromatase inhibitors (AIs). In the current study, a two-way approach for the identification of novel leads has been adapted. 81 chemical compounds were assessed to understand their potentiality against aromatase along with the four known drugs. Docking was performed employing the CDOCKER protocol available on the Discovery Studio (DS v4.5). Exemestane has displayed a higher dock score among the known drug candidates and is labeled as reference. Out of 81 ligands 14 have exhibited higher dock scores than the reference. In the second approach, these 14 compounds were utilized for the generation of the pharmacophore. The validated four-featured pharmacophore was then allowed to screen Chembridge database and the potential Hits were obtained after subjecting them to Lipinski's rule of five and the ADMET properties. Subsequently, the acquired 3,050 Hits were escalated to molecular docking utilizing GOLD v5.0. Finally, the obtained Hits were consequently represented to be ideal lead candidates that were escalated to the MD simulations and binding free energy calculations. Additionally, the gene-disease association was performed to delineate the associated disease caused by CYP19A1.

Strong light scattering and broadband (UV to IR) photoabsorption in stretchable 3D hybrid architectures based on Aerographite decorated by ZnO nanocrystallites. Sci Rep 2016; 6:32913. [PMID: 27616632 PMCID: PMC5018730 DOI: 10.1038/srep32913] [Citation(s) in RCA: 47] [Impact Index Per Article: 5.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/13/2016] [Accepted: 08/17/2016] [Indexed: 11/23/2022] Open
Abstract
In present work, the nano- and microscale tetrapods from zinc oxide were integrated on the surface of Aerographite material (as backbone) in carbon-metal oxide hybrid hierarchical network via a simple and single step magnetron sputtering process. The fabricated hybrid networks are characterized for morphology, microstructural and optical properties. The cathodoluminescence investigations revealed interesting luminescence features related to carbon impurities and inherent host defects in zinc oxide. Because of the wide bandgap of zinc oxide and its intrinsic defects, the hybrid network absorbs light in the UV and visible regions, however, this broadband photoabsorption behavior extends to the infrared (IR) region due to the dependence of the optical properties of ZnO architectures upon size and shape of constituent nanostructures and their doping by carbon impurities. Such a phenomenon of broadband photoabsorption ranging from UV to IR for zinc oxide based hybrid materials is novel. Additionally, the fabricated network exhibits strong visible light scattering behavior. The developed Aerographite/nanocrystalline ZnO hybrid network materials, equipped with broadband photoabsorption and strong light scattering, are very promising candidates for optoelectronic technologies.
