Abstract
The novel N-tert-butoxycarbonyl (Boc)-3-aminomethyl pyridine (NBAMP) was analyzed by density functional theory (DFT) quantum chemical method. The B3LYP method with 6–311++ G (d,p) basis set were employed to obtain the optimized structure, vibrational wavenumbers, electronic properties and the molecular electrostatic potential surface (MEP). The vibrational frequencies were assigned using the potential energy distribution (PED) calculation. UV-Vis spectrum was simulated by TD-DFT method, which is also observed experimentally. The 13C NMR spectrum of NBAMP molecule was simulated and observed using Gauge-Invariant-atomic orbital (GIAO) method with DMSO solution and their chemical shifts were calculated and observed. The natural bond orbital analysis (NBO) was used to predict the donor-acceptor interactions. The reactive sites were obtained by fukui function analysis. The nucleophilic and electrophilic sites were predicted by molecular electrostatic potential surface (MEP). The mulliken atomic charge distribution was calculated for NBAMP molecule. Intra-molecular charge transfer was predicted by frontier molecular orbitals (FMO) and NBO. To identify the potential applications of the NBAMP molecule, the molecular docking analysis was carried out and the molecular docking results revealed that the NBAMP molecule may be useful for drug designing in the treatment of amyotrophic lateral sclerosis.
