The unrelenting menace of the Lassa virus, characterized by its high mortality rate and potential for global dissemination, underscores an urgent call comprehensive eradication to safeguard public health. In light this, this research embarked on extensive investigation trans-N-feruloyltyramine (FLTM), a compound derived from Cissampelos pareira. This study encompassed thorough examination structural characteristics, utilizing spectroscopic analyses including FT-IR, UV, NMR, with aim elucidating electronic, structural, biological properties. Seamlessly integrating experimental theoretical approaches at DFT/B3LYP/def2SVP level theory in FLTM_dmso, FLTM_gas, FLTM_H2O, FLTM_MeOH solvation. Moreover, solvation dynamic simulation highlighted FLTM's heightened total energy enhanced solubility across dimethyl sulfoxide (DMSO), water (H2O), methanol (MeOH) phases, signifying efficient distribution target sites emphasizing as drug candidate. Conversely, FLTM_gas exhibited lower energy. Electronic properties further elucidated reactivity kinetic stability, FLTM_DMSO displaying lowest gap among solvents corresponding values 1.4168, 4.2159, 4.2175, 4.2749 eV. These findings mirrored compound's higher stability compared FLTM_MeOH, aligning principles chemical hardness softness. Results molecular docking introduced FLTM fever treatment candidate, surpassing Ribavirin binding affinities virus receptors. energies -6.5 kcal/mol, -7.2 -8.2 kcal/mol 7UOT, 3MX5, 3MX2, respectively, establishing interactions crucial amino acid residues. strongly advocate efficacy, meriting vitro vivo investigations clinical validation.

This study employed density functional theory (DFT) computational techniques at the ωB97XD/def2svp level of to comprehensively explore electronic behavior Fe-group transition metal (Fe, Ru, Os) coordination Se-doped graphitic carbon (Se@g-C3N4) nanosystems in smart delivery zidovudine (ZVD), an antiretroviral drug. The HOMO-LUMO results interactions show a general reduction energy gap values across all complexes following order: ZVD_Se@C3N4 < ZVD_Ru_Se@C3N4 ZVD_Fe_Se@C3N4 ZVD_Os_Se@C3N4. exhibits smallest post-interaction band 3.783 eV, while ZVD_Os_Se@C3N4 presents highest 5.438 eV. Results from corrected adsorption (BSSE) revealed that Os_Se@C3N4 and Ru_Se@C3N4 demonstrated more negative energies -2.67 -2.701 respectively, pointing favorable interaction between ZVD these systems, thus potentially enhancing drug efficiency. investigation into release mechanism adsorbents involved comprehensive examination dipole moment influence pH, shedding light on controlled ZVD. Additionally, investigating decomposition analysis (EDA) exhibited same total -787.7 kJ mol-1. intriguing similarity their levels suggested stability was governed by factors beyond reactivity, possibly due intricate orbital interactions. Furthermore, analyzing bond dissociation showed systems enthalpy values, indicating were exothermic both surface levels, suggesting processes emitted heat, contributing surrounding thermal energy.
