Allosteric α1-Adrenoreceptor Antagonism by the Conopeptide ρ-TIA [PDF]

open access: yesJournal of Biological Chemistry, 2003
A peptide contained in the venom of the predatory marine snail Conus tulipa, rho-TIA, has previously been shown to possess alpha1-adrenoreceptor antagonist activity. Here, we further characterize its pharmacological activity as well as its structure-activity relationships.

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

open access: yesMarine 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 ...

Analgesic effect of recombinant GABAergic precursors releasing ω-conotoxin MVIIA in a model of peripheral nerve injury in rats

open access: yesMolecular Pain, 2022
Development of chronic pain has been attributed to dysfunctional GABA signaling in the spinal cord. Direct pharmacological interventions on GABA signaling are usually not very efficient and often accompanied by side effects due to the widespread ...

Overexpression, purification, and pharmacological activity of a biosynthetically derived conopeptide [PDF]

open access: yesBiochemical and Biophysical Research Communications, 2005
A high yielding fusion protein system based on the protein cytochrome b(5) has been used for the production of novel 13-residue acyclic conopeptide. This peptide, Mo1659, can be liberated from the carrier protein using CNBr cleavage and subsequent purification using RP-HPLC methods. The yield of isotopically enriched peptides is high, ranging from 3 to

Bioactive Compounds Isolated from Neglected Predatory Marine Gastropods

open access: yesMarine Drugs, 2018
A diverse range of predatory marine gastropods produce toxins, yet most of these molecules remain uncharacterized. Conus species have received the most attention from researchers, leading to several conopeptides reaching clinical trials. This review aims

Glycosylation of Conotoxins

open access: yesMarine Drugs, 2013
Conotoxins are small peptides present in the venom of cone snails. The snail uses this venom to paralyze and capture prey. The constituent conopeptides display a high level of chemical diversity and are of particular interest for scientists as tools ...

A novel inhibitor of α9α10 nicotinic acetylcholine receptors from Conus vexillum delineates a new conotoxin superfamily. [PDF]

open access: yesPLoS ONE, 2013
Conotoxins (CTxs) selectively target a range of ion channels and receptors, making them widely used tools for probing nervous system function. Conotoxins have been previously grouped into superfamilies according to signal sequence and into families based

Characterization of a Novel Conus bandanus Conopeptide Belonging to the M-Superfamily Containing Bromotryptophan

open access: yesMarine Drugs, 2014
A novel conotoxin (conopeptide) was biochemically characterized from the crude venom of the molluscivorous marine snail, Conus bandanus (Hwass in Bruguière, 1792), collected in the south-central coast of Vietnam.

Toxins 'R' Us : more pharmacological tools from nature's superstore

open access: yes, 2002
Conus venoms from marine cone snails continue to provide novel bioactive components. Two new classes of conopeptide specifically block alpha(1)-adrenoceptors (rho-conopeptide) and noradrenaline transporters (chi-conopeptides).

Solution structures and conformational isomerism of novel conopeptides from Indian marine cone snails

open access: yes, 2020
This thesis describes the structure determination of peptides found in marine cone snails’ venom at atomic resolution and their biological activity. Chapter 1 gives a brief introduction to the cone snails, conopeptides, and basic NMR to determine the ...
