Cyclopropanation reactions between C-60 and different malonates decorated with monosaccharides and steroids using the Bingel-Hirsch methodology have resulted in the synthesis of a new family of hybrid compounds. The chemical structures of these compounds were determined using instrumental techniques and cyclic voltammetry revealed their unique reductive pattern. Theoretical calculations and molecular docking simulations provided insights into their stability, geometry, and potential applications in biomedicine.
Cyclopropanation reactions between C-60 and different malonates decorated with monosaccharides and steroids using the Bingel-Hirsch methodology have allowed the obtention of a new family of hybrid compounds in good yields. A complete set of instrumental techniques has allowed us to fully characterize the hybrid derivatives and to determine the chemical structure of monocycloadducts. Besides, the proposed structures were investigated by cyclic voltammetry, which evidenced the exclusive reductive pattern of fullerene Bingel-type monoadducts. Theoretical calculations at the DFT-D3(BJ)/PBE 6-311G(d,p) level of the synthesized conjugates predict the most stable conformation and determine the factors that control the hybrid molecules ' geometry. Some parameters such as polarity, lipophilicity, polar surface area, hydrophilicity index, and solvent-accessible surface area were also estimated, predicting its potential permeability and capability as cell membrane penetrators. Additionally, a molecular docking simulation has been carried out using the main protease of SARS-CoV-2 (Mpro) as the receptor, thus paving the way to study the potential application of these hybrids in biomedicine.
