title: A solution-phase combinatorial synthesis of selective dopamine D4 ligands.
abstract: Utilizing combinatorial synthesis and a preparative LC-MS automated chromatography system we have prepared and purified a library of 4-[2-(1,2,4-oxadiazolyl)]piperidines that were designed to be novel and selective dopamine D4 ligands. In one round of synthesis we identified N-4-chlorobenzyl-4-[2-(3-(2-thienyl)-1,2, 4-oxadiazolyl)]piperidine with a Kd of 5 nM for the human D4 receptor.
