Isoindol-1-one Analogues of 4-(2‘-methoxyphenyl)-1-[2‘-[<i>N</i>-(2‘‘-pyridyl)-<i>p</i>-iodobenzamido]ethyl]piperazine (<i>p</i>-MPPI) as 5-HT<sub>1A</sub> Receptor Ligands

moderate to low brain uptakes with little or no specific localization in hippocampal region, where 5-HT1Areceptors are concentrated. These data indicate that the new iodinated ligands showed high binding affinities and better metabolic stability but displayed unexpectedly low selective binding to 5-HT1Areceptors in vivo. Additional structural modifications may be needed to correct the unfavorable properties
Complementary Synthetic Approaches to Constitutionally Diverse N-Aminoalkylated Isoindolinones: Application to the Synthesis of Falipamil and 5-HT1A Receptor Ligand Analogues
Different synthetic approaches for the elaboration of poly and diversely substituted isoindolinones tailed with constitutionally diverse aminoalkylated chains have been developed. The key step is based upon the preliminary assembly of the isoindolinone template equipped with hydroxyalkyl appendages. Subsequent manipulation of the terminal hydroxy functionality afforded the targeted compounds and the
