  (Pyridylcyanomethyl)piperazines as orally active PAF antagonists

  摘要：

  A series of (pyridylcyanomethyl)piperazines was prepared and evaluated for PAF-antagonist activity. Compounds were tested in vitro in a PAF-induced platelet aggregation assay and in vivo in a PAF-induced hypotension test in normotensive rats. Oral activity was ascertained through a PAF-induced mortality test in mice. The main structure-activity trends of the series were established. Activity was mainly found in four skeletons: 1-acyl-4-(3-pyridylcyanomethyl)-piperazine, 1-acyl-4-(4-pyridylcyanomethyl)piperazine, 1-acyl-4-(3-pyridylcyanomethyl)piperidine, and 1-acyl-4-cyano-4-(3-pyridylamino)piperidine. The acyl substituents, diphenylacetyl and 3,3-diphenylpropionyl, provided the most active compounds, and the introduction of an amine or hydroxy group in the 3,3-diphenylpropionyl substituent led to further improvement in oral activity. As a result, three of the most active compounds (100, 114, and 115) have been selected for further pharmacological development.
