Drugs that rescue function of episodic ataxia 1 (EA1) mutant potassium channels are lacking. Here, Manville et al identify and describe the molecular basis for Native American botanical ataxia remedies that directly rescue EA1 mutant channels.

Substituting a hydrogen atom with its heavy isotope deuterium may improve the pharmacokinetic and/or toxicity profile of a drug compared with its non-deuterated counterpart. This article highlights milestones in the field of deuteration in drug discovery and development, and discusses recent examples of its application, which have shifted towards deuteration of novel drug candidates instead of developing deuterated analogues of marketed drugs.

This study shows that the insulinotropic actions of the dual GIPR and GLP-1R agonist, tirzepatide, depend on GIPR, and that tirzepatide has weaker activity at the mouse GIPR than murine GIP.

The single nucleotide polymorphism C115Y in the IL-23 receptor is associated with autoinflammatory diseases. Here the authors demonstrate that this mutation prevents the binding of a fluorescent cyclic peptide and IL-23 to the IL-23 receptor.
