• Opis:
  Studies on the interactions between cucurbituril Q7 and gemcitabine (Gem) hydrochloride in water were carried out using isothermal titration calorimetry (ITC) and electrospray ionization–mass spectrometry (ESI-MS). According to ITC and ESI-MS, the formation of this complex occurs in both the solution containing excess gemcitabine and the solution containing excess cucurbituril Q7. ITC results confirm the formation of a thermodynamically stable supramolecular complex with stoichiometry 1:1. The inclusion mechanism of Gem inside the cucurbituril macromolecule is spontaneous (ΔG<0). This process is exothermic (ΔH<0) and is characterized by the loss of entropy (ΔS<0).;
  The study was financed from the Grant for Development of Young Researchers from the Faculty of Chemistry, University of Lodz, 2017.
