Unlike orthosteric ligands that bind directly to the receptor's active site, allosteric modulators target Over the past decade, there has been a notable growth in the discovery of allosteric modulators for GPCRs functional and/or affinity for an orthosteric ligand; and negative allosteric modulators (NAMs), that In this context, allosteric modulators exhibiting constrained positive or negative cooperativity are SBI-553, an allosteric modulator of NTSR1, provides valuable insights into how allosteric modulation
