Chemical Synthesis and NMR Solution Structure of Conotoxin GXIA from Conus geographus

Marine Drugs, 2021
Conotoxins are disulfide-rich peptides found in the venom of cone snails. Due to their exquisite potency and high selectivity for a wide range of voltage and ligand gated ion channels they are attractive drug leads in neuropharmacology.

Synthesis, Pharmacological and Structural Characterization of Novel Conopressins from Conus miliaris

Marine Drugs, 2020
Cone snails produce a fast-acting and often paralyzing venom, largely dominated by disulfide-rich conotoxins targeting ion channels. Although disulfide-poor conopeptides are usually minor components of cone snail venoms, their ability to target key ...

Toxins from cone snails: properties, applications and biotechnological production [PDF]

Applied Microbiology and Biotechnology, 2008
AbstractCone snails are marine predators that use venoms to immobilize their prey. The venoms of these mollusks contain a cocktail of peptides that mainly target different voltage- and ligand-gated ion channels. Typically, conopeptides consist of ten to 30 amino acids but conopeptides with more than 60 amino acids have also been described. Due to their

Toxinology of Marine Venomous Snails

Iranian South Medical Journal, 2021
A surprisingly large number of sea snail species are venomous. Cone snail venoms are produced in a lengthy tubular duct from a complex venom gland and form a cocktail of many toxins, particularly conotoxins which have high potency and specificity for ...

Mitogenomic phylogeny of cone snails endemic to Senegal

Molecular Phylogenetics and Evolution, 2017
Cone snails attain in Senegal one of their highest peaks of species diversity throughout the continental coast of Western Africa. A total of 15 endemic species have been described, all placed in the genus Lautoconus. While there is ample data regarding the morphology of the shell and the radular tooth of these species, virtually nothing is known ...

Curses or Cures: A Review of the Numerous Benefits Versus the Biosecurity Concerns of Conotoxin Research

Biomedicines, 2020
Conotoxins form a diverse group of peptide toxins found in the venom of predatory marine cone snails. Decades of conotoxin research have provided numerous measurable scientific and societal benefits.

Prey Shifts Drive Venom Evolution in Cone Snails [PDF]

Molecular Biology and Evolution
Abstract Venom systems are complex traits that have independently emerged multiple times in diverse plant and animal phyla. Within each venomous lineage there typically exists interspecific variation in venom composition where several factors have been proposed as drivers of variation, including phylogeny and diet.

The introduction of marine cone snail species from the coast of the Qeshm Island, contains conotoxin palliative pain in mice [PDF]

بوم‌شناسی آبزیان, 2019
Conotoxins are small toxic peptides that are synthesized in cone snail venom ducts. Conotoxins have analgesic effects in models animal. In this study, the analgesic effects with no toxicity of Persian Gulf cone snails, Conus coronatus, and Conus frigidus

Multimodal AI‐Driven Identification of Dehydrocostus Lactone as a Potent Renal Fibrosis Attenuator Targeting IQGAP1

Advanced Science, EarlyView.
Renal fibrosis, a hallmark of CKD, lacks effective treatments. Herein, we developed a multimodal AI model (TCM‐SPred) to identify anti‐fibrotic agents and found that dehydrocostus lactone (DCL) targets IQGAP1 to inhibit Wnt signaling, blocking the interaction between IQGAP1 and CCT3, demonstrating potent anti‐fibrotic activity in vitro and in vivo ...
