Abstract
ABSTRACTThe aim of this paper is a better comprehension of the encapsulation and interaction an anticancer drug Altretamine into BN nano ring [BNNR(9,9-5)] and AlN nano ring [AlNNR(9,9-5)]. The electronic and adsorption properties of the molecule Altretamine over the BNNR and AlNNR were theoretically studied in the solvent phase at the B3LYP/6-31G* level of theory for the first time. With the non-bonded interaction of Altretamine, the electronic properties of the BN and AlN nano-cages can be significantly changed. The electronic spectra of the Altretamine drug, complex BNNR/Altretamine and AlNNR/Altretamine in solvent water were calculated by Time Dependent Density Functional Theory (TD-DFT) for the investigation of adsorption effect. According to the natural bond orbital (NBO) results, the molecule Altretamine, BNNR and AlNNR play as both electron donor and acceptor at the complexes BNNR/Altretamine and AlNNR/Altretamine. On the other hand, the charge transfer is occurred between the bonding, antibonding or nonbonding orbitals in the molecule drug, BNNR and AlNNR. As a consequence, BNNR(9,9-5) and AlNNR(9,9-5) can be considered as a drug delivery system for the transportation of Altretamine as anticancer drug within the biological systems.
