Abstract Efficient determination of proteinogenic amino acid is great relevance, and evaluating the intrinsic interaction this interest with nanotubes play a crucial role in adsorption sensing mechanism, determining measurement index. As such, study apparently sought to examine (proline) on bare surfaces carbon boron nitride, nitride doped aluminum element nanotubes. In accordant geometric optimization, different dispersion models: PBE0, ωB97XD, M06‐2X, B3LYP‐D3(GD3BJ) were used; note that latter used only wave function analysis studies. Studies show strongest belongs (BNAl dop NT), similar more negative energy ‐0.719, ‐1.393, ‐1.001, ‐1.098eV respectively for various benchmarked functionals utilized study. Then highest strength was obtained nanotube (BNNT), at end (i.e. BNAl NT > BNNT BC 2 NNT). tandem energetic carried out suggests might be potent preferred candidate (proline molecule)among other studied nanotubes, respect their respective values

Rhenium complexes have been observed experimentally to exhibit good inhibitory activity against malignant cells. Hence, our motivation is explore this from a theoretical perspective. In the present study, density functional theory (DFT) and in silico molecular docking approaches were utilized unravel unique properties of metal-based rhenium tricarbonyl as effective anticancer drugs. All DFT calculations geometric optimizations conducted using well-established hybrid B3LYP-GD(BJ)/Gen/6-311++G(d,p)/LanL2DZ computational method. The FT-IR spectroscopic characterization complexes: fac-[Re(Pico)(CO)3(Pz)] (R1), fac-[Re(Pico)(CO)3(Py)] (R2), fac-[Re(Dfpc)(CO)3(H2O)] (R3), fac-[Re(Dfpc)(CO)3(Pz)] (R4), fac-[Re(Dfpc)(CO)3(Py)] (R5), fac-[Re(Tfpc)(CO)3(H2O)] (R6), fac-[Re(Tfpc)(CO)3(Py)] (R7), fac-[Re(Tfpc)(CO)3(Im)] (R8) was explored. To gain insights into electronic structural properties, bioactivity, stability these complexes, highest occupied orbital–lowest unoccupied orbital analysis, binding energy, topological analysis based on quantum atoms-in-molecules considered. activities measured via human BCL-2 protein (IG5M) proapoptotic (agonist) BAX 1 (450O). results showed that studied exhibited affinity (−3.25 −10.16 kcal/mol) could cause significant disruption normal physiological functions proteins. also are suitable candidates for development agents.
