Design, Synthesis, Characterization, Molecular Docking, MM/GBSA and Biological Evaluation of Thiazolidinones Derivatives as Promising Antibacterial and Antifungal Agents Shabnam Thakur, Mohini Kalra, Naveen Khatri, Ritu Dahiya Asian Journal of Chemistry, 2026 In present study, a series of 24 thiazolidinone derivatives (TH7-TH30) was rationally designed as potential antibacterial and antifungal agents, of which twelve compounds (TH7-TH18) were successfully synthesized and fully characterized using IR, 1H NMR, 13C NMR, and HRMS techniques. The antimicrobial activity of the synthesized derivatives was evaluated by the tube dilution method, and minimum inhibitory concentrations (MICs) were determined against selected bacterial and fungal strains. To elucidate the molecular basis of activity, in silico studies were performed on all designed compounds using molecular docking with the Glide module of Schrödinger 9.6. Docking investigations targeted MurB (PDB ID: 7OSQ) and lanosterol 14-α demethylase (PDB ID: 5V5Z), key enzymes involved in bacterial cell wall synthesis and fungal sterol biosynthesis, respectively. Binding modes were further analyzed through superimposition with standard inhibitors, streptomycin for MurB and ketoconazole for lanosterol 14-α demethylase. The stability and binding free energies of the docked complexes were assessed using MM/GBSA calculations. Furthermore, ADMET properties of the designed derivatives were predicted using QikProp (v3.5) to evaluate drug-likeness, oral bioavailability and gut blood barrier permeability. Based on the combined experimental and computational findings, novel thiazolidinone derivatives emerge as promising lead structures for the further development of antibacterial and antifungal agents.
Structural Phase Transition and Magnetic Properties in Mn2−xCuxSnS4 (x = 0, 0.05, 0.1, 0.6, 0.7): From Defect Rock Salt to Disordered Spinel Prasanjit Agasti, Nunavath Ramakrishna, Aman Mishra, Sachindra Nath Sarangi, Saroj L. Samal European Journal of Inorganic Chemistry, 2026 Orthorhombic Mn 2 SnS 4 with defect‐ordered rock salt structure exhibits complex magnetic properties with two magnetic transitions, antiferromagnetism at around 152 K and a weak ferromagnetism at 53 K. In this article, we have studied the effect of copper(I) substitution on the structure and magnetic properties of Mn 2− x Cu x SnS 4 . A structural phase transition from orthorhombic defect‐ordered rock salt structure, Cmmm (for x = 0.05 and 0.1) to cubic spinel structure, Fd −3 m ( x = 0.6 and 0.7) is observed with Cu substitution in Mn 2− x Cu x SnS 4 . In the defect‐ordered rock salt structure, Cu goes to the octahedral Mn site, while in the spinel structure, Cu along with Mn goes to tetrahedral voids. With initial Cu(I) substitution in the orthorhombic phase, the low‐temperature weak ferromagnetic ordering temperature increases from 53 K to about ∼140 K and ∼120 K for x = 0.05 and 0.1, respectively, while the high‐temperature antiferromagnetic ordering temperature remains invariant. Higher amount of Cu substitution in Mn 2− x Cu x SnS 4 leads to structural transformation of orthorhombic to a cubic spinel phase (0.6 ≤ x ≤ 0.7), in which the magnetic ions occupy both tetrahedral and octahedral voids in a disordered manner resulting in further lowering of magnetic ordering temperature.
SUPERIOR ANTIBACTERIAL FEATURES OFZnONANOPARTICLES PREPARED BY Azadirachta indica: MEDIATED GREEN SYNTHESIS ROUTE S Ghadai, Suchismita Acharya, M Sahoo, M. P Mishra, S. K Biswal, S. N Sarangi Rasayan Journal of Chemistry, 2026 Zinc oxide nanoparticles exhibit size- and morphology-dependent properties strongly influenced by synthesis routes. We report ZnO nanoparticles prepared via chemical co-precipitation [ZnO(C)] and a green route using Azadirachtaindica leaf extract [ZnO(G)]. Furthermore, their structure–property correlations have been systematically studiedbyseveral characterization methods. Formation of a hexagonal wurtzite ZnO phase was confirmed by X-ray diffractionanalysis, revealing that ZnO(G) possessed comparatively smaller crystallite sizes, a result of the controllednucleation and growth imparted by phytochemicals present in the Azadirachta indica extract. FESEManalysisrevealed irregular agglomerates in ZnO(C), whereas ZnO(G) exhibited uniform spherical structures. UV–Vis spectrashowed strong near-UV absorption, with band gaps of ~3.60 eV (ZnO(C)) and ~3.63 eV (ZnO(G)), the latter slightlyredshifted by defect states and biomolecule interactions. Antibacterial tests against Escherichia coli (E. coli) and Staphylococcus aureus (S. aureus) showed stronger inhibition for ZnO(G), attributed to residual phytoconstituents and altered surface chemistry. Overall, synthesis pathways dictate crystallite size, morphology, optical bandgap, and antimicrobial activity, highlighting Azadirachta indica-mediated green synthesis as asustainable route to prepare nano ZnO for biomedical use.
Ligand tunability of emergent noncollinear magnetism in Cu-based layered hybrid perovskites P. Biswal, Sagar Sarkar, S. N. Sarangi, Arvind Kumar Yogi, Subhendra D. Mahanti, G. Tripathy, Ashis K. Nandy, Diptikanta Swain, D. Samal Physical Review B, 2025 Transition metal-based layered organic-inorganic hybrid perovskites (OIHPs) exhibit diverse magnetic phenomena, yet the atomistic origin of magnetism in this class of materials remains elusive after decades of study. Here we demonstrate a notable ligand tunability of magnetism in two new quasi-two-dimensional OIHPs (${\mathrm{C}}_{7}{\mathrm{H}}_{9}\mathrm{NBr}$)${}_{2}{\mathrm{CuX}}_{4}$ (${\mathrm{C}}_{7}{\mathrm{H}}_{9}\mathrm{NBr}$ = 4-Bromobenzylammonium = A, X = Cl, Br) from comprehensive magnetic measurements and provide its microscopic understanding supported by ab initio DFT calculations. Despite being isostructural and having easy plane magnetocrystalline anisotropy (MCA), the Cl and Br analogs exhibit contrasting magnetic response. While ${\mathrm{A}}_{2}{\mathrm{CuCl}}_{4}$ shows an in-plane ferromagnetic and out-of-plane antiferromagnetic-like response, ${\mathrm{A}}_{2}{\mathrm{CuBr}}_{4}$ follows the reverse trend. The origin of this intriguing behavior is argued to stem from Dzyaloshinskii-Moriya interaction (DMI) present in these layered systems. We quantify DMI by employing constrained noncollinear DFT calculations in the presence of SOC which otherwise is challenging in the domain of OIHPs due to their large system size. Based on the competition between DMI and MCA, we propose a canted and transverse conical spiral spin structure for ${\mathrm{A}}_{2}{\mathrm{CuCl}}_{4}$ and ${\mathrm{A}}_{2}{\mathrm{CuBr}}_{4}$, respectively, which captures the observed magnetic response. Our study provides an effective way of tailoring and understanding the occurrence of nontrivial spin textures in this class of OIHPs.
Reconfigurable Phototactic Micromotors from Fractal Self-Assembly of Dark Carbon Nanodot Sols: A Perfect Mimic of Colonial Green Algae Somnath Koley, Shraban Dey, Debopam Acharjee, Mrinal Kanti Panda, Jit Satra, Sachindra Nath Sarangi, Tapas Kuila, Karuna Kar Nanda Advanced Materials Technologies, 2025 Bottom‐up synthesized carbon nanodots (CNDs) are surface‐active, biocompatible nanomaterials well‐known for their bright photoluminescence properties. This paper introduces the potential of dark (non‐emissive) CNDs in crafting phototactic micro‐motors. Hydrogen bond mediated fractal self‐assembly of dark CNDs manifests colloidal superstructures with hierarchical dimensions in alcohol media resembling properties of natural green algae in terms of appearance, phototactic movement, and colony dynamics. Akin to the natural counterpart, the characteristic helical microswimming, and bi‐directional phototaxis following the gradient of light and shade by a school of swimmers are observed, establishing the unprecedented intelligence of any artificial constructs to date. The artificial algae produce a photocurrent upon light exposure, which drives the phototactic motility. Laser beam‐directed anti‐gravity propulsion implies the potentiality of these biocompatible micro‐motors for cargo‐delivery and microsurgery applications. In the condensed phase, alco‐algae reversibly transform to green‐transmitting leafy architectures that turn golden‐brown upon aging, resembling natural photosynthetic organisms. In one direction, this study establishes an inexpensive and powerful approach for crafting intelligent artificial living systems from bio‐available precursors. Furthermore, it pushes the boundaries of applications that can be achieved by CNDs.
Internal and external magnetic-field engineering of negative magnetization and exchange bias in L a1-x P rxCr O3 (0.8≤x≤0.9) Deepak Garg, Amit Kumar, S. M. Yusuf, Markos Skoulatos, Sachindra Nath Sarangi, Dinesh Topwal, Yixi Su Physical Review Materials, 2025 The negative magnetization and exchange bias phenomena have been the subject of interest due to their promising applications in spintronic devices. In this study, we have comprehensively investigated these two intertwined magnetic phenomena in La1−xPrxCrO3 (x=0.8−0.9) compounds. The Cooke's model fit to dc magnetization data infers negative internal magnetic field for x=0.8, 0.85, and 0.87 and positive for x=0.9. The crossover of internal magnetic field from negative to positive across x=0.87 and its dominance over the external applied magnetic field leads to the magnetization switching from negative to positive. The internal magnetic field behavior also explains the anomalous magnetization behavior involving reduced magnetization for x=0.87, despite having higher Pr3+ concentration than that for x=0.8 and 0.85. The anomalous magnetization is corroborated well by the neutron depolarization experiments, where no depolarization is observed for x=0.87 owing to nearly compensated domain magnetization. Remarkably, a switching of the exchange bias from inverse (with positive HEB) to conventional (with negative HEB) due to a competition of external and internal magnetic fields is found in x=0.8 and 0.85 compounds. The x=0.87 and 0.9 compounds, on the other hand, show only conventional exchange bias at all measured magnetic fields. Using the Cooke's model, we show that the antiferromagnetic coupling between polarized Pr3+ and weak ferromagnetic component of canted Cr3+ moments explain not only the inverse exchange bias but the conventional exchange bias as well, however, the moment orientations are different for both types of exchange bias. Moreover, our study demonstrates that the ferromagnetic coupling between the two moments can also lead to conventional exchange bias, similar to that observed in interfacial heterostructure systems.
