Insights That Move the GPCR Field Forward

The first time Michelle ran a cyclic AMP assay, she did it with a single-channel pipette, trays of melting ice, and the kind of focus that only comes from knowing one mistake could waste weeks of work.

Drug discovery pipelines often stall not because the target is wrong—but because the chemical matter interacting with that target lacks the right properties to produce meaningful pharmacology. We obsess over target validation, signaling pathways, expression patterns, and disease relevance. Yet, far less time is spent scrutinizing the structural logic and origin of the molecules we screen in the first place.

Each edition highlights the decisions that move GPCR projects forward—from pharmacology essentials to ligand binding site strategies, bench-ready tools, and industry momentum shaping GPCR pipelines. Read fast, apply faster, and stay ahead in GPCR drug discovery with evidence-based insights—no hype, just strategies you can use.

This week’s insights give you a strategic edge across the pipeline—from drug design that accounts for physiological counterforces, to simplifying internalization detection without microscopy, to boosting HTRF assay sensitivity using fluorescent ligands. It’s a curated toolkit designed to help GPCR professionals move faster, with more confidence. Premium Members count on this every week—and this is your preview.

Early signals can mislead. This week’s Dr. GPCR Weekly shows how to call Mechanism of Action with model-first rigor—distinguishing orthosteric vs. allosteric, designing assays that reveal mechanism, and unlocking SAR. Plus: Novo’s \$550M obesity/diabetes push, Rhythm’s sNDA, key events, and confocal imaging that respects function. Upgrade to Premium for the full digest.
