Conformational Properties and Putative Bioactive Targets for Novel Thiosemicarbazone Derivatives
The structure assignment and conformational analysis of the thiosemicarbazones, <b>DKI21</b> and <b>DKI24</b>, were performed through homonuclear and heteronuclear 2D Nuclear Magnetic Resonance (NMR) spectroscopy (2D-COSY, 2D-NOESY, 2D-ROESY, 2D-HSQC, and 2D-HMBC) and quantum...

| description | The structure assignment and conformational analysis of the thiosemicarbazones, <b>DKI21</b> and <b>DKI24</b>, were performed through homonuclear and heteronuclear 2D Nuclear Magnetic Resonance (NMR) spectroscopy (2D-COSY, 2D-NOESY, 2D-ROESY, 2D-HSQC, and 2D-HMBC) and quantum mechanics (QM) calculations, using Functional Density Theory (DFT). In addition, utilizing a combination of 2D-NOESY and 2D-ROESY spectra an <i>exo</i> structure was established for both of the analogs. This experimental results were confirmed by theoretical mechanistic studies, as the lowest minima conformations derived through DFT calculations were compatible with the spatial correlations observed in the 2D-NOESY and 2D-ROESY spectra. Finally, molecular binding experiments were performed to detect the potential targets for <b>DKI21</b> and <b>DKI24</b>, derived from SwissAdme. <i>In silico</i> molecular binding experiments showed favorable binding energy values for the most of the enzymes studied. The ADMET calculations, using the preADMET and pKCSm software, showed that the two molecules appear as possible drug leads. |
