Synthesis and Biological Activity of Novel α-Conotoxins Derived from Endemic Polynesian Cone Snails

open access: yesMarine Drugs, 2023
α-Conotoxins are well-known probes for the characterization of the various subtypes of nicotinic acetylcholine receptors (nAChRs). Identifying new α-conotoxins with different pharmacological profiles can provide further insights into the physiological or

Design of New α-Conotoxins: From Computer Modeling to Synthesis of Potent Cholinergic Compounds

open access: yesMarine Drugs, 2011
A series of 14 new analogs of α-conotoxin PnIA Conus pennaceus was synthesized and tested for binding to the human α7 nicotinic acetylcholine receptor (nAChR) and acetylcholine-binding proteins (AChBP) Lymnaea stagnalis and Aplysia californica.

Systematic dissection of genomic features determining the vast diversity of conotoxins

open access: yesBMC Genomics, 2023
Background Conus, a highly diverse species of venomous predators, has attracted significant attention in neuroscience and new drug development due to their rich collection of neuroactive peptides called conotoxins.

Satellite Glial Cells Synthesize and Release GABA to Activate Extrasynaptic GABAA Receptors That Modulate Dorsal Root Ganglia Neuron Excitability

open access: yesGlia, Volume 74, Issue 9, September 2026.
Mechanism of synthesis, release, receptor activation, uptake, and degradation of GABA in dorsal root ganglia (DRG). Left: GABA is synthesized from putrescine in satellite glial cells (SGCs). After being released by Best1 channel, it activates GABAA receptors in sensory neurons, producing a chloride current.

Conotoxins: natural product drug leads

open access: yes, 2009
Venomous marine cone snails harbour a variety of small disulfide-rich peptides called conotoxins, which target a broad range of ion channels, membrane receptors, and transporters.

Discovery of Novel Conotoxin Candidates Using Machine Learning

open access: yesToxins, 2018
Cone snails (genus Conus) are venomous marine snails that inject prey with a lethal cocktail of conotoxins, small, secreted, and cysteine-rich peptides.

Peripheral κ opioid receptor in pain and inflammation: From molecular signalling and gene expression to drug discovery

open access: yesBritish Journal of Pharmacology, Volume 183, Issue 17, Page 5157-5189, September 2026.
The κ opioid receptor (κ receptor, KOR) is a G protein‐coupled receptor with well established roles in analgesia and immune modulation. Although historically studied primarily in the central nervous system (CNS), growing evidence indicates that κ signalling in peripheral tissues plays an important role in regulating pain, inflammation and immune ...

Codon bias for - and -conotoxins.

open access: yes, 2013
(A) shows the data for the -conotoxins, and (B) shows the data for the -conotoxins. Values presented are the weighted average of values (sensu [43], Eq. 2) for codons encoding amino acids that can be represented by two (and only two) codons. Because the

Prolonging the Efficacy of Botulinum Toxin A Using a Novel Toxin Mimetic Complex and Peptide Formulation

open access: yesJournal of Cosmetic Dermatology, Volume 25, Issue 9, September 2026.
ABSTRACT Background Botulinum toxin type A (BTX‐A) is the cornerstone for treating dynamic wrinkles; however, it requires reinjection every 3–4 months. Adjunctive topical creams that mimic the effect of BTX‐A and enhance its action may prolong treatment intervals.
