Exploration of Pipecolate Sulfonamides as Binders of the FK506-Binding Proteins 51 and 52: Complex of FKBP51 with 2-(3-((R)-1-((S)-1-(3,5-dichlorophenylsulfonyl)piperidine-2-carbonyloxy)-3-(3,4-dimethoxy -phenyl)propyl)phenoxy)acetic acid
FK506-binding proteins (FKBP) 51 and 52 are co-chaperones that modulate the signal transduction of steroid hormone receptors. Single nucleotide polymorphisms in the gene encoding FKBP51 have been associated with a variety of psychiatric disorders. Rapamycin and FK506 are two macrocyclic natural products, which tightly bind to all these proteins. A bio-isosteric replacement of the alpha-ketoamide moiety of rapamycin and FK506 with a sulfonamide was envisaged with the retention of the conserved hydrogen bonds. A focused solid support-based synthesis protocol was developed, which led to ligands with submicromolar affinity for FKBP51 and FKBP52. The molecular binding mode for one sulfonamide analog was confirmed by X-ray crystallography.
