Alpha9 nicotinic acetylcholine receptors and the treatment of pain [PDF]

open access: yes, 2009
Chronic pain is a vexing worldwide problem that causes substantial disability and consumes significant medical resources. Although there are numerous analgesic medications, these work through a small set of molecular mechanisms.

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.

Stabilization of α-conotoxin AuIB: Influences of disulfide connectivity and backbone cyclization [PDF]

open access: yes, 2011
alpha-Conotoxins are peptides isolated from the venom ducts of cone snails that target nicotinic acetylcholine receptors (nAChRs). They are valuable pharmacological tools and have potential applications for treating a range of conditions in humans ...

The Tetrodotoxin Receptor of Voltage-Gated Sodium Channels—Perspectives from Interactions with μ-Conotoxins

open access: yesMarine Drugs, 2010
Neurotoxin receptor site 1, in the outer vestibule of the conducting pore of voltage-gated sodium channels (VGSCs), was first functionally defined by its ability to bind the guanidinium-containing agents, tetrodotoxin (TTX) and saxitoxin (STX ...

Calcium channels controlling acetylcholine release from preganglionic nerve terminals in rat autonomic ganglia [PDF]

open access: yes, 1999
Little is known about the nature of the calcium channels controlling neurotransmitter release from preganglionic parasympathetic nerve fibres. In the present study, the effects of selective calcium channel antagonists and amiloride were investigated on ...

The Evolution of Fangs, Venom, and Mimicry Systems in Blenny Fishes [PDF]

open access: yes, 2017
Venom systems have evolved on multiple occasions across the animal kingdom, and they can act as key adaptations to protect animals from predators. Consequently, venomous animals serve as models for a rich source of mimicry types, as non-venomous ...

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

Evolution: Fangtastic Venoms Underpin Parasitic Mimicry [PDF]

open access: yes, 2017
Venomous teeth are rare in fishes, which typically utilise spines for defence. A new study reveals the evolutionary origins of fangs and venom in the Nemophini blennies and shows that, in contrast to snakes and lizards, the fangs pre-date the ...
