✦ Synopsis

A molecule library containing 42 1-[3-(arylpiperazin-1-yl)-propyl]-pyrrolidin-2-one derivatives has been designed and synthesized. The phospholipophilicity of the obtained compounds has been determined using immobilized artificial membrane high-performance liquid chromatography (IAM-HPLC). The performed analysis allowed the calculation of log k we values for each of the tested compounds. Experimental phospholipophilicity data (log k we ) has been compared with the affinity of the tested compounds to α 2 -adrenoceptors. Performed quantitative structure-activity relationship studies indicated that, for the tested compounds, there are dependences between affinity for α 2 -adrenoceptors and their log k we values. The obtained results confirmed that the applied chromatographic IAM-HPLC method could be useful in fast characterization of the phosholipophilicity of structurally closely related compounds as well as for larger series of compounds, such as drug candidates. It could also be used as a tool for further research into this group of compounds.
