We report the synthesis and extensive characterization of Diazepane and Oxazepane derivatives, followed by their biological evaluation. These compounds were assessed for in vitro and in vivo antimicrobial, anti-inflammatory, and anticancer activities. Among the synthesized molecules, compound 5b demonstrated remarkable antibacterial activity against Staphylococcus aureus and Staphylococcus epidermidis with MIC values of 20 and 40 ��g/mL, respectively. Additionally, 5b exhibited potent anti-inflammatory effects both in vitro and in vivo. Advanced computational studies, including DFT, MEP, RDG, and ELF analyses, were performed to understand the electronic distribution and molecular interactions. The bioactivity and physicochemical properties of these derivatives were further predicted using PASS and pkCSM platforms, emphasizing their potential as promising lead molecules in drug development.
