Abstract
AbstractWe synthesized cinnamic acid derivatives of ethyl cinnamate (EC) and analyzed the resulting products using 1H‐NMR and FTIR spectroscopy. The formation of the confirmed EC and γ‐Cyclodextrin inclusion complex is investigated through UV–vis and fluorescence spectroscopy. Cyclic voltammetry techniques are employed to analyze the formation of the inclusion complex. By using Job's plot, the stoichiometric ratio of the inclusion complex is found to be 1:1, and the binding constant (K) is calculated through the Benesi‐Hildebrand plot. Furthermore, we calculated the thermodynamic parameters (ΔG) using the Gibbs‐Helmholtz free energy equation, indicating that the formation of this inclusion complex is spontaneous. The molecular interaction between EC and the hydrophobic cavity of γ‐CD is characterized using 2D NMR (ROESY), revealing their specific interactions. Research highlights the need for antibacterial studies due to the rise of new infectious diseases. Specifically, the study investigates the antibacterial activity of inclusion complexes compared to the guest molecule alone.
