Parallel synthesis and biological screening of dopamine receptor ligands taking advantage of a click chemistry based BAL linker

J Comb Chem. Mar-Apr 2005;7(2):309-16. doi: 10.1021/cc049860s.

Abstract

The click-chemistry-derived formyl indolyl methyl triazole (FIMT) resin 1a was evaluated for the parallel solid-phase synthesis of a series of BP-897-type arylcarboxamides. By application of a five-step sequence (including loading by reductive amination, subsequent amide coupling, deprotection, palladium-catalyzed N-arylation, and acidic cleavage), a focused library of putative dopamine D3 receptor ligands was constructed. The final products revealed good to excellent purity and were screened for binding at monoaminergic G-protein-coupled receptors when selected library members proved to show excellent binding affinity, especially toward the dopamine D3 receptor subtype.
