Abstract
In our pursuit of designing potent bioactive compounds, we synthesized six novel tellurium (IV) complexes through the condensation of 5‐methyl‐2‐thiophene carboxaldehyde and p‐nitroaniline. These compounds underwent rigorous investigation using various analytical techniques (TGA, SEM, EDAX, and powder XRD) and spectral analyses (NMR, mass spectrometry, UV–Vis, and FTIR). Spectroscopic analysis suggested an octahedral geometry for the complexes, revealing chelation through the thiophene sulfur and azomethine nitrogen atoms. Thermal analysis indicated a three‐step degradation process, ultimately leaving behind metal oxide as the end product. We conducted in‐vitro antimicrobial screening using the broth micro‐dilution method, highlighting the significant antimicrobial and antioxidant properties of complexes 3c and 3d, as well as the potent antimicrobial activity of 3b and 3f against various bacterial strains, including Candida albicans. To further substantiate our findings, we performed advanced computational analyses, including molecular docking, pharmacophore modeling, DFT, MESP, and ADMET studies. Molecular docking validated our antimicrobial results, whereas pharmacophore models enhanced our understanding of molecular interactions with proteins, potentially identifying novel bioactive compounds. Furthermore, DFT and MESP investigations underscored the superior biological efficacy of tellurium (IV) complexes over thiophene‐derived ligands, emphasizing their potential as therapeutic agents. ADMET analysis revealed their favorable profile as precursors for drug development with minimal adverse effects. In summary, our research seamlessly integrates experimental and theoretical aspects, offering innovative insights into drug design and potential applications in pharmaceuticals. This study represents a significant milestone, paving the way for future advancements in the field of pharmaceutical science.
