Welcome back GPCR lovers,
In pharmacology, the wrong interpretation of antagonist behavior can derail your conclusions, your experiments, and even your program’s credibility. That’s why mastering competitive vs non-competitive antagonism isn’t optional — it’s essential for accurate, defensible science.
This week, Terry’s Corner takes you beyond curve shapes into the kinetic and mechanistic realities that separate surface-level analysis from true expertise.
Breakthroughs this week: FFA4 receptor signaling controls lipolysis at lipid droplets; novel atypical GPCR-arrestin complexes; Lilly's oral GLP-1, orforglipron, delivers weight loss of up to an average of 27.3 lbs in first of two pivotal Phase 3 trials in adults with obesity.

Terry's Corner - Demystifying Antagonism: The Key to Precision Drug Discovery
Understanding the nuances of competitive versus non-competitive antagonism is a cornerstone of effective drug discovery. Without a solid grasp of these concepts, scientists risk misinterpreting critical data, leading to flawed decisions and wasted resources.
This week in Terry’s Corner, we go beyond the dose-response curves to explore the kinetic and pharmacologic signatures of antagonism. Dr. Kenakin’s expert guidance provides a clear framework for distinguishing these mechanisms and avoiding common pitfalls that can derail a program.
Don't let misconceptions about receptor binding kinetics slow your progress—gain the clarity you need to move forward with confidence.
Solve the problem of misinterpreting your data by understanding how slow-offset kinetics can mimic classical patterns, leading to incorrect mechanistic assignments.
Gain a competitive edge by asking the right questions about binding kinetics and experimental constraints, ensuring your analysis is robust and your decisions are sound.
Avoid the professional threat of flawed data interpretations that can lead to costly dead ends and missed opportunities in your drug discovery program.

Yamina's Consulting Corner - Building Your GPCR Program for Breakthroughs, Not Breakdowns
In the fast-paced world of GPCR drug discovery, the "go fast" mindset can often lead to costly breakdowns. Yamina’s Corner tackles the critical disconnect between brilliant science and operational strategy, revealing why throwing more money and people at a problem is a multi-million dollar mistake.
This week, we introduce a new series, "The GPCR Precision Blueprint," which provides a systematic framework to ensure your science, strategy, and execution are seamlessly aligned.
Learn how to transform your program from a series of disconnected efforts into a predictable, de-risked pathway to success.
Solve the problem of a fragmented approach by learning how to build a unified system where every scientific detail and strategic decision aligns.
Gain a competitive edge by transforming your GPCR data from chaos into a strategic asset, enabling faster, more confident decision-making.
Avoid the professional threat of financial friction and missed investment opportunities by learning to translate operational precision into a compelling narrative for stakeholders.
Three takeaways from this week’s feature:
Stop firefighting: Learn why solving isolated problems burns capital without fixing root causes.
Bridge science and strategy: Ensure data and decision-making align with funding and milestones.
Build predictable success: Use a repeatable improvement framework to turn operational chaos into precision execution.
