α‐RgIB: A Novel Antagonist Peptide of Neuronal Acetylcholine Receptor Isolated from Conus regius Venom

open access: yesInternational Journal of Peptides, Volume 2013, Issue 1, 2013., 2013
Conus venoms are rich sources of biologically active peptides that act specifically on ionic channels and metabotropic receptors present at the neuromuscular junction, efficiently paralyzing the prey. Each species of Conus may have 50 to 200 uncharacterized bioactive peptides with pharmacological interest.

A Benchmark Dataset Comprising Partition and Distribution Coefficients of Linear Peptides

open access: yesDataset Papers in Science, Volume 2013, Issue 1, 2013., 2013
Peptides have a dominant role in biology; yet the study of their physical properties is at best sporadic. Peptide quantitative structure‐activity relationship (QSAR) lags far behind the QSAR analysis of drug‐like organic small molecules. Traditionally, QSAR has focussed on experimentally determined partition coefficients as the main descriptor of ...

Excitation–contraction coupling inhibitors potentiate the actions of botulinum neurotoxin type A at the neuromuscular junction

open access: yesBritish Journal of Pharmacology, Volume 182, Issue 3, Page 564-580, February 2025.
Abstract Background and Purpose Botulinum neurotoxin type A1 (BoNT/A) is one of the most potent neurotoxins known. At the same time, it is also one of the safest therapeutic agents used for the treatment of several human disorders and in aesthetic medicine.

Prey specificity of predatory venoms

open access: yesBiological Reviews, Volume 99, Issue 6, Page 2253-2273, December 2024.
ABSTRACT Venom represents a key adaptation of many venomous predators, allowing them to immobilise prey quickly through chemical rather than physical warfare. Evolutionary arms races between prey and a predator are believed to be the main factor influencing the potency and composition of predatory venoms.

δ‐Conotoxin Structure Prediction and Analysis through Large‐Scale Comparative and Deep Learning Modeling Approaches

open access: yesAdvanced Science, Volume 11, Issue 35, September 18, 2024.
δ‐Conotoxins are a diverse class of peptides that inhibit the inactivation of voltage‐gated sodium channels – proteins implicated in many human diseases – but which remain poorly characterized. Computational modeling of 18 different δ‐conotoxins using traditional and deep learning techniques uncovers structural features underlying the varying ...
