A library consisting of 60 arylpiperazines modified with N-acylated amino acids was prepared on BAL linker SynPhase (TM), Lanterns and evaluated in vitro for 5-HT1A receptor affinity. Biological screening, followed by a simple Fujita Ban analysis, enabled the description of structure-activity relationships and allowed the selection of some potent, high-affinity ligands for in vivo pharmacological investigations.

Novel class of arylpiperazines containing N-acylated amino acids: Their synthesis, 5-HT1A, 5-HT2A receptor affinity, and in vivo pharmacological evaluation
SynPhase Lanterns, were prepared in solution and their affinity for 5-HT(1A), 5-HT(2A), and D(2) receptors was evaluated. The compounds bearing (3-acylamino)pyrrolidine-2,5-dione (19-26) and N-acylprolinamide (29-34) moieties showed high affinity for 5-HT(1A) (K(i)=3-47 nM), high-to-low for 5-HT(2A) (K(i)=4.2-990 nM), and low for D(2) receptors (K(i)=0.77-21.19 microM).
