Abstract
En 中文
Our investigation involves the analysis of perylene diimide (PDI) through DFT estimation, evaluating its potential as a drug carrier framework for Hesperetin, Melphalan, Mercaptopurine, Resveratrol, and Zidovudine. Analysis of the bond lengths between the interacting atoms indicates that PDI demonstrates exceptional carrier capabilities for the delivery of Hesperetin, Melphalan, Mercaptopurine, Resveratrol, and Zidovudine, with measurements of 2.10, 1.82, 2.24, 2.01, and 2.46 & Aring;, respectively. The presence of hydrogen bonding interactions can be analyzed through Noncovalent Interaction (NCI) and Quantum Theory of Atoms in Molecules (QTAIM) methodologies. The dipole moments and chemical descriptors indicate the significant reactivity of the PDI nanocarriers with Hesperetin, Melphalan, Mercaptopurine, Resveratrol, and Zidovudine drugs. According to the analysis of optoelectronic properties, PDI@Mercaptopurine demonstrates a significant adsorption affinity for the perylene diimide (PDI) complex in comparison to other complexes. Moreover, the release of Mercaptopurine from the nanocarrier is enhanced by the stability of adsorption during protonation in an acidic environment, in conjunction with the brief recovery time anticipated for the PDI nanocarrier surface. After considering all the factors mentioned before, it is clear that PDI nanocarriers have a lot of promise as anticancer drug delivery methods.
