How Ligands Illuminate GPCR Molecular Pharmacology

Abstract

G protein-coupled receptors (GPCRs), which are modulated by a variety of endogenous and synthetic ligands, represent the largest family of druggable targets in the human genome. Recent structural and molecular studies have both transformed and expanded classical concepts of receptor pharmacology and have begun to illuminate the distinct mechanisms by which structurally, chemically, and functionally diverse ligands modulate GPCR function. These molecular insights into ligand engagement and action have enabled new computational methods and accelerated the discovery of novel ligands and tool compounds, especially for understudied and orphan GPCRs. These advances promise to streamline the development of GPCR-targeted medications.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Slightly more than half of non-olfactory GPCRs have annotated drugs and small molecules targeting them.

    “Slightly more than half of the non-olfactory GPCRs have annotated drugs and small molecules targeting them53,54,61; see also TABLE 1.”

    From Unexplored therapeutic opportunities in the human genome (2018) · cites this paper as [53]

    The Introduction section on understudied and orphan GPCRs describes GPCR-targeted drugs and annotated small-molecule interactors. It does not give a count or proportion of non-olfactory GPCRs with such annotations, so it does not support the claim that the proportion is slightly more than half. (LLM, conf=0.76)

  • A handful of GPCRs, mainly biogenic amine, muscarinic and opioid receptors, are the most abundantly targeted receptors for FDA-approved medications.

    “A recent analysis indicates, however, that a handful of GPCRs — mainly biogenic amine, muscarinic and opioid receptors — represent the most abundantly targeted receptors for FDA-approved medications53,54.”

  • Alterations in GPCR signalling are implicated in the pathogenesis and treatment of many disorders, including neuropsychiatric, immunological, gastrointestinal, cardiac, renal, hormonal and infectious disorders.

    “Alterations in GPCR signalling are implicated in the pathogenesis and treatment of neuropsychiatric55, immunological56, gastrointestinal57,58, cardiac59, renal, hormonal, infectious60 and many other disorders53,54.”

  • GPCRs are the largest family of druggable targets in the human genome, with 20-30% of approved drugs acting on them.

    “GPCRs represent the largest family of druggable targets in the human genome9, with between 20% and 30% of approved drugs acting on them53,54.”

  • GPCRs are membrane-bound cell-surface receptors that transduce signals via heterotrimeric G proteins, arrestins and other cellular transducers.

    “GPCRs are membrane-bound, cell-surface receptors that transduce signals via interactions with heterotrimeric G proteins, arrestins and other cellular transducers53,54.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
