RETENTION BEHAVIOR AND BIOLOGICAL ACTIVITY OF N-SUBSTITUTED-2-PHENYLACETAMIDE DERIVATES
Phenylacetamide derivatives are a group of compounds that exhibit a wide range of biological activities as analgetic, anticonvulsant, pesticide, cytostatic. It is well known that the biological activity and the field of activity of the substance are greatly dependent on its physical, chemical and structural properties. In this paper, we applied QSRR analysis (Quantitative Structure Retention Relationships), which is based on the prediction of biological properties of compounds based on their chromatographic retention behaviors. To that end, retention constants of investigated N-substituted-2-phenylacetamide were determined by reversed phase thin-layer chromatography, (HPTLC RP18 F254s) in the presence of different volume fractions of n-propanol and tetrahydrofuran. The resulting data were correlated with molecular descriptors determined in different ways in order to establish the mathematical model that describes the relationship between retention properties and biological activities of investigated phenylacetamides.
