Predictions from modeling inform chemistry. Chemistry fuels assays. Assay data flows back into models. The cycle only works because every part is connected .   His group is trained to explain exactly what a model can predict and where its limits are. Biased signaling, allosteric binding sites, and subtype selectivity mean there is rarely a straight line He treats modeling as part of a continuum rather than a separate discipline.

October 2022 "G protein-coupled receptors (GPCRs) are important drug targets characterized by a canonical seven transmembrane (TM) helix architecture. Recent advances in X-ray crystallography and cryo-EM have resulted in a wealth of GPCR structures that have been used in drug design and formed the basis for mechanistic activation hypotheses. Here, ensemble refinement (ER) of crystallographic structures is applied to explore the impact of binding of agonists and antagonist/inverse agonists to selected structures of cannabinoid receptor 1 (CB1R), β2 adrenergic receptor (β2 AR) and A2A adenosine receptor (A2A AR).

receptors (GPCRs), including the parathyroid hormone 1 receptor (PTH1R), a class B GPCR and an important modulator the activation of PTH1R and its downstream signaling, we describe here that RAMP2 acts as a specific allosteric modulator of PTH1R, shifting PTH1R to a unique preactivated state that permits faster activation in Moreover, RAMP2 modulates PTH1R downstream signaling in an agonist-dependent manner, most notably increasing of RAMPs in the activation and signaling of a GPCR that may provide a new venue for highly specific modulation

Why Allosteric Modulation Is the Productive Route The same structural account points toward the alternative An allosteric modulator does not need to engage the orthosteric contact network at all. Family B GPCRs have a rich history of allosteric ligands that produce activation. It also suggests that allosteric modulation deserves earlier consideration than it sometimes receives orthosteric small molecules are not well positioned to fill.

October 2022 Mechanism of enhanced sensitivity of mutated β-adrenergic-like octopamine receptor to amitraz in honeybee Apis mellifera: An insight from MD simulations "Background: Amitraz is one of the critical acaricides/insecticides for effective control of pest infestation of Varroa destructor mite, a devastating parasite of Apis mellifera, because of its low toxicity to honeybees. Previous assays verified that a typical G protein-coupled receptor, β-adrenergic-like octopamine receptor (Octβ2R), is the unique target of amitraz, but the honeybee Octβ2R resists to amitraz. However, the underlying molecular mechanism of the enhanced sensitivity or toxicity of amitraz to mutated honeybee Octβ2RE208V/I335T/I350V is not fully understood. Here, molecular dynamics simulations are employed to explore the implied mechanism of the enhanced sensitivity to amitraz in mutant honeybee Octβ2R."

Biased pharmacological modulators provide potential therapeutic benefits, including greater pharmacodynamic Therefore, the identification of such modulators as drug candidates is highly desirable. The biased signaling modulation of non-GPCR receptors has yet to be exploited.

Although many cardiovascular GPCRs have been extensively studied as model receptors for decades, new As a result, there is an ongoing need to develop novel approaches to monitor and to modulate GPCR activation

An alternative and promising approach is allosteric modulation. Over the past decade, there has been a notable growth in the discovery of allosteric modulators for GPCRs Allosteric modulators that do not exhibit agonistic properties remain inactive in the absence of endogenous In this context, allosteric modulators exhibiting constrained positive or negative cooperativity are modulators with a diminished risk of target-related toxicity (Wold et al. 2018).
