Computational Study of the Interaction of C12P12 and C12N12 Nanocages with Alendronate Drug Molecule

Abstract The utilization of nanomaterials as efficient delivery systems to specific metabolic sites is essential for harnessing the utmost therapeutic potency of drugs leading to a tremendous quest in the design of efficient drug delivery systems. In this present study, appropriate level of quantum chemical calculation by applying DFT/ωB97XD/6‐311G+ (d, p) method was utilized to investigate the effectiveness of C 12 N 12, and C 12 P 12 nanocages as delivery systems for alendronate drug. The properties of an ideal nano‐delivery system with regards to potential constraints during fabrication are being considered. The highest adsorption energy in C 12 N 12 was observed in interaction site CN_CH −7.355 eV while interaction site CP_CH was observed with the highest Eads −3.518 eV for C 12 P 12. These interaction sites in studied nanocages are suitable for the delivery of alendronate to target site. Our results for energy gap show that studied nanocages are good for the delivery of alendronate drug. The natural bond orbital analysis confirms nanocages and various interactions to be stable. Non‐covalent interaction and quantum theory of atoms in molecules were used to probe the effectiveness of the nanomaterials as delivery materials and confirms strong interaction between drug alendronate and nanocages.
