AI Article Synopsis

  • The study focuses on the synthesis of thioguanine (TG)-capped gold nanoparticles (Au@TG) and assesses their effectiveness against various bacteria and cancer cells.
  • It investigates how TG binds to the gold nanoparticles through different scientific methods such as UV-Vis spectrum and TEM.
  • The results indicate that Au@TG exhibits stronger antimicrobial and anticancer properties compared to TG alone, suggesting gold nanoparticles could serve as effective drug delivery systems for cancer treatment.

Article Abstract

Synthesis of thioguanine (TG)-capped Au nanoparticles (Au@TG) and their enhanced in vitro antimicrobial and anticancer efficacy against Micrococcus luteus, Staphylococcus aureus, Pseudomonas aeruginosa, E. coli, Aspergillus fumigatus, Aspergillus niger and Hep2 cancer cell (Human epidermiod cell) have been reported. The nature of binding between 6-TG and the gold nanoparticles via complexation is investigated using ultraviolet-visible spectrum, cyclic voltammetry, transmission electron microscopy, fluorescence and Fourier transform infrared (FT-IR) spectroscopy. The present experimental studies suggests that Au@TG are more potential than TG towards antimicrobial and anticancer activities. Hence, gold nanoparticles have the potential to be used as effective carriers for anticancer drug.

Background: Enterovirus 71 (EV71) is one of the major causative agents of hand, foot, and mouth disease (HFMD), and can cause severe cerebral complications and even fatality in children younger than 5 years old. However, there is no specific medication for EV71 infection in clinical practice. Our previous studies had identified the 6-thioguanine (6-TG), an FDA-approved anticancer drug, as a potential antiviral agent, but its anti-EV71 activity is largely unknown, therefore, we aim to explore the antiviral effect of 6-TG on EV71.

A range of heterocyclic compounds, including Isatin (oneH-indole-2, 3-dione) and its by-products, have been shown to represent potential unit blocks in the synthesis of potential medicinal agents. Numerous studies have been carried out on isatin, its synthesis, biological uses, and its chemical composition since when it was discovered. Functionally, these isatin-containing heterocycles have demonstrated antibacterial, antidiabetic, antiviral, antitubercular, and anticancer properties, among many others.
