Study the nature of interaction between 5-Fluorouracil anti-cancer drug and borospherene

This study employs density functional theory (DFT) to evaluate pristine C₄B₃₂ borospherene and borospherenes functionalized by amino acid in drug delivery efficiency. The results showed that pristine and alanine-modified C₄B₃₂ clusters demonstrated high efficiency in drug delivery when borospherenes were designed using the quadruple carbon atom doping of C₄B₃₂. The main goal of this study was to evaluate the interaction between the 5-Fluorouracil drug (FU) and borospherenes (both alanine-modified variants and pristine). According to the findings, the bio-drug delivery function enabled by the amino acid led to enhanced FU adsorption onto C₄B₃₂, and in the ultraviolet-visible (UV-Vis) spectroscopy, a redshift was found in the drug@cluster electronic spectra. Therefore, it can be concluded that the borospherene modified by alanine offers drug delivery efficiency.
