Lipophilicity Studies on Thiosemicarbazide Derivatives

Molecules. 2017 Jun 8;22(6):952. doi: 10.3390/molecules22060952.

Abstract

The lipophilicity of two series of thiosemicarbazide derivatives was assessed by the RP-HPLC method with the RP-18 chromatographic column and the methanol-water mixture as the mobile phase. Distribution coefficients logPHPLC were compared to calculated values generated by commonly used AClogP software and quantum chemical calculations. The reliability of the predictions was evaluated using the correlation matrix and PCA. For 4-benzoylthiosemicarbazides, a high correlation between theoretical and experimental logP parameters was obtained using the XlogP3 algorithm, while for 4-aryl/(cyclohexyl)thiosemicarbazides, the XlogP2 parameter was strongly correlated with the experimentally obtained logP.

Keywords: PCA; RP-HPLC; bacterial type IIA topoisomerases; logP; thiosemicarbazide derivatives.
