After the structure identification of the compounds, various conformations of the two compounds were calculated using DFT. The two molecules showed the most energy-favorable values when their two double bonds adopted the E configuration. These configurations were compatible with the spatial correlations observed in the 2D-NOESY spectrum. In addition, due to the various isomers that occurred, the energy of the transition states from one isomer to another was calculated. Finally, molecular binding experiments were performed to detect potential targets for KKI15 and KKI18 derived from SwissAdme. In silico molecular binding experiments showed favorable binding energy values for all four enzymes studied. The strongest binding energy was observed in the enzyme butyrylcholinesterase. ADMET calculations using the preADMET and pKCSm software showed that the two molecules appear as possible drug leads.}, number={8}, journal={Molecules (Basel, Switzerland)}, author={Georgiou, Nikitas and Katsogiannou, Aikaterini and Skourtis, Dimitrios and Iatrou, Hermis and Tzeli, Demeter and Vassiliou, Stamatia and Javornik, Uroš and Plavec, Janez and Mavromoustakos, Thomas}, year={2022}, month={Apr} }
