The Journal of Physiology, Volume 604, Issue 18, Page 7799-7818, 15 September 2026.Abstract figure legend Contrary to the prevailing view, the therapeutic efficacy of sodium channel blockers in myotonia does not depend on inhibition of the transient sodium current (NaT) responsible for action potentials. In a mouse model of myotonia congenita, effective concentrations of sodium channel blockers did not reduce NaT, but consistently ...

Pharmacological Inhibition of Cav2.2 Channels by Recombinant Phα1β Toxin (CTK01512‐2)
Basic &Clinical Pharmacology &Toxicology, Volume 139, Issue 2, August 2026.The recombinant Phα1β toxin (CTK01512‐2) partially and reversibly inhibits Cav2.2 calcium channels in HEK‐293 cells. CTK01512‐2 displays dose‐dependent inhibition of N‐type calcium currents, with an IC50 of 3.94 nM. In vivo, CTK01512‐2 effectively reduces mechanical allodynia in a neuropathic pain model, confirming its antinociceptive activity ...

Structure-activity studies on alpha-conotoxins
, 2011 Conotoxins are small bioactive highly structured peptides from the venom of marine cone snails (genus Conus). Over the past 50 million years these molluscs have developed a complex venom cocktail for each species that is comprised of 100-2000 distinct ...

Neuronal Nicotinic Acetylcholine Receptor Modulators from Cone Snails
Marine Drugs, 2018 Marine cone snails are a large family of gastropods that have evolved highly potent venoms for predation and defense. The cone snail venom has exceptional molecular diversity in neuropharmacologically active compounds, targeting a range of receptors, ion

A Structure‐Informed Atlas of Venom‐Derived Peptides Reveals the Organization of Chemical Space
Molecular Informatics, Volume 45, Issue 5, May 2026.A structure‐informed atlas integrating sequence and AlphaFold‐derived features across 3,423 venom peptides reveals that chemical space is organized by disulfide‐stabilized compactness and electrostatic–hydrophobic balance, with functional classes clearly separated and convergent design principles overriding taxonomic origin.

Molecular basis for a pore block of Tentonin 3 expressed in HEK293 cells by a conopeptide, NMB‐1
British Journal of Pharmacology, Volume 183, Issue 9, Page 1845-1859, May 2026.Background and Purpose Tentonin 3 (TTN3/TMEM150C) is a mechanosensitive ion channel that plays critical roles in mechanotransduction processes. TTN3 forms a tetramer with a predicted rectangular shape and a central pore. A conotoxin ρ‐TIA and its synthetic analog, noxious mechanosensation blocker 1 (NMB‐1), were initially developed to inhibit slowly ...
