title: Somatostatin sst4 ligands: chemistry and pharmacology.
abstract: Several classes of compounds (thioureas, ureas, beta-glucosides, sulfonamides, and cyclic peptides) show enhanced binding affinity and selectivity at somatostatin subtype 4 receptors (sst4). Pharmacophore models have recently been proposed to explain receptor subtype selectivity. The chemistry and therapeutic potential of sst4 ligands will be the subject of this review.
