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.

Recombinant Expression and Characterization of α-Conotoxin LvIA in Escherichia coli

open access: yesMarine Drugs, 2016
α-Conotoxin LvIA is derived from Conus lividus, native to Hainan, and is the most selective inhibitor of α3β2 nicotinic acetylcholine receptors (nAChRs) known to date.

SPIDR: small-molecule peptide-influenced drug repurposing

open access: yesBMC Bioinformatics, 2018
Background Conventional de novo drug design is costly and time consuming, making it accessible to only the best resourced research organizations. An emergent approach to new drug development is drug repurposing, in which compounds that have already gone ...

Erratum to: The crystal structure of Ac-AChBP in complex with α-conotoxin LvIA reveals the mechanism of its selectivity towards different nAChR subtypes

open access: yesProtein & Cell, 2017
In the original publication of the article the keywords are incorrectly online published. The correct keywords should read as α-Conotoxin; Nicotinc acetylcholine receptor; Acetylcholine binding protein; X-ray crystallography”.

Unravelling the allosteric binding mode of αD-VxXXB at nicotinic acetylcholine receptors

open access: yesFrontiers in Pharmacology, 2023
αD-conotoxins are 11 kDa homodimers that potently inhibit nicotinic acetylcholine receptors (nAChRs) through a non-competitive (allosteric) mechanism. In this study, we describe the allosteric binding mode of the granulin-like C-terminal (CTD) of VxXXB ...

Inflammation Regulation via an Agonist and Antagonists of α7 Nicotinic Acetylcholine Receptors in RAW264.7 Macrophages

open access: yesMarine Drugs, 2022
The α7 nicotinic acetylcholine receptor (nAChR) is widely distributed in the central and peripheral nervous systems and is closely related to a variety of nervous system diseases and inflammatory responses.

Interactions of Globular and Ribbon [γ4E]GID with α4β2 Neuronal Nicotinic Acetylcholine Receptor

open access: yesMarine Drugs, 2021
The α4β2 nAChR is implicated in a range of diseases and disorders including nicotine addiction, epilepsy and Parkinson’s and Alzheimer’s diseases. Designing α4β2 nAChR selective inhibitors could help define the role of the α4β2 nAChR in such disease ...

Sensitive Detection of α-Conotoxin GI in Human Plasma Using a Solid-Phase Extraction Column and LC-MS/MS

open access: yesToxins, 2017
α-conotoxin GI, a short peptide toxin in the venom of Conus geographus, is composed of 13 amino acids and two disulfide bonds. It is the most toxic component of Conus geographus venom with estimated lethal doses of 0.029–0.038 mg/kg for humans.

Characterisation of a Novel A-Superfamily Conotoxin

open access: yesBiomedicines, 2020
Conopeptides belonging to the A-superfamily from the venomous molluscs, Conus, are typically α-conotoxins. The α-conotoxins are of interest as therapeutic leads and pharmacological tools due to their selectivity and potency at nicotinic acetylcholine ...
