faster, and stay ahead in GPCR drug discovery with evidence-based insights—no hype, just strategies you can Breakthroughs this week: New work clarifies how active-state GPCR conformations can support coupling Available in four formats, it turns a notoriously tricky measurement into something discovery teams can pharmacology—showing how persistence, precision, and the courage to take on “impossible” chemistry can B y integrating them into GPCR workflows, discovery teams can accelerate identification, characterization

achieve this, the work of Heydenreich et al. (2023) will be analysed to demonstrate how mutagenesis can By identifying key β2AR residues that influence efficacy and potency, pharmaceutical researchers can For example, orthosteric drug design —in which drugs bind to the receptor’s primary active site—can now Alternatively, allosteric modulators , which bind to sites outside the traditional ligand-binding pocket, can Understanding the evolutionary conservation of these residues can lead to the development of drugs that

Redefining Opioid Pharmacology Ben and his colleagues discovered that PAMs can dramatically increase His work highlights how foundational GPCR science can drive therapeutic innovation.

“ A substitution of one amino acid by another in a protein can have effects ranging from negligible to While these structural techniques offer significant advantages in drug discovery, no single method can Furthermore, data on the role of specific residues within receptors can provide valuable insights for Through either random or targeted (site-directed) approaches, mutagenesis can provide a comprehensive In summary, mutagenesis can be a critical tool in drug discovery, particularly for studying GPCRs.

For complex GPCR systems, this boundary is a strategic advantage: NAMs can only shift an agonist curve Kenakin  showed how the same agonist can behave as near-full, partial, or even silent depending on receptor This is why experts never classify ligands from a single system: The same molecule can occupy different Kenakin  stressed that low-alpha NAMs can resemble competitive antagonists unless deeper kinetic or concentration-range Extremely strong binders can fail in structured tissues because they saturate the periphery and never

. 👉 How long can we operate if fundraising takes longer than expected? Which decisions can we still reverse, and which ones are already locked in? creates the illusion of control 👉 Many biotech founders  believe they are in control because they can They manage cash flow, but they do not actively track which strategic decisions can still be changed In reality, this is the last window where control can still be regained.

Redundancy can be exemplified by the tumor infiltration of Treg cells which can be driven directly by This redundancy can be seen as problematic in drug discovery as blocking a single receptor might not the chemokine-receptor system, different chemokines are able to activate different pathways, which can Signaling bias can be seen as complex as advantageous since selectively inhibiting certain signaling pathways while sparing others, can prevent some of the negative off-target effects.

“…now you have a plethora of 400 models that you can start with molecular dynamics, docking, virtual iteratively refining the models with docking and mutagenesis data, they developed predictive pipelines that can

Yet one well-timed question can unlock clarity, accelerate a stalled project, or even spark a collaboration s a masterclass in asking better questions in science, not as a skill you’re born with, but one you can I’m running into a problem and I know you work on something similar — can I pick your brain for one minute

He emphasizes that not every question can be answered computationally—and that saying “we don’t know” In a field where major publications and grant awards can be rare, finding satisfaction in an optimized Modeling a Career on Your Own Terms Carlsson’s career shows that failures can evolve into strengths and that computational insights can transform how we approach GPCRs. early-career researchers, the takeaway is direct: GPCR drug discovery will increasingly depend on those who can

BBVs are nanoparticles covered with Sf9 cell membranes different from mammalian membranes,[9] which can affect receptors’ properties.[10,11] BBVs also lack downstream signaling components, which can be an The speed of reaching the binding equilibrium is key for this assay, which can be monitored over time Altogether, these aspects hint that the linker design and strategy can provide options for the tuning CELT-419 binding to D3 receptors in cells can be clearly visualized with fluorescence imaging.

Positioning 👉 Most biotech founders feel that something is wrong in external conversations long before they can stop adjusting their message mid-conversation , which increases confidence and coherence Alignment can Investors and partners can quickly assess relevance. Founders can quickly assess interest. External stakeholders can decide faster, and founders waste less energy trying to adapt. ✅ If every conversation

They give the comforting sense that progress can be measured and managed . Teams believe they can correct course by adjusting execution. How Founders Can Strengthen Strategic Decision Making Early Once founders recognize the role of early decisions and understand how alignment works, the next question becomes practical. 👉 How can strategic Founders who define when and how decisions can be challenged reduce fear and defensiveness later on.
