Insights That Move the GPCR Field Forward

A peptide stabilizes a GPCR active state through multiple contact points a small molecule structurally cannot reach. That asymmetry is the reason biologics exist as a distinct therapeutic class — and the reason their ADME, safety, and pharmacology don't map onto small-molecule frameworks.

GPCR internalization does not end signaling — it redirects it. This article explores the assays, beta-arrestin gating mechanisms, and recycling-versus-degradation frameworks that determine receptor fate inside the cell.

Modern drug discovery produces thousands of compounds—but only pharmacology turns assay signals into predictions. Explore the drug discovery pharmacology principles guiding receptor signaling, potency interpretation, residence time, and real-world drug behavior.
