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

The two disulfide bonds of α-conotoxin ImI, a peptide antagonist of the α7 nicotinic acetylcholine receptor (nAChR), were systematically replaced with isosteric redox-stable cystathionine thioethers. Regioselective thioether formation was accomplished on

α-Conotoxin GIC is a 16-residue peptide isolated from the venom of the cone snail Conus geographus. α-Conotoxin GIC potently blocks the α3β2 subtype of human nicotinic acetylcholine receptor, showing a high selectivity for neuronal versus muscle subtype [

Characterisation of a Novel A-Superfamily Conotoxin
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 ...

Among the brain tumors, glioma is the most common. In general, different biochemical mechanisms, involving nicotinic acetylcholine receptors (nAChRs) and the arachidonic acid cascade are involved in oncogenesis.

Cancer pain: current practice and emerging targets
Cancer pain (CP) arises from a complex interplay between the tumour and its microenvironment. Many patients experience a mixed pain phenotype that encompasses nociceptive, neuropathic and neuroinflammatory mechanisms, and vary across tumour type and disease stage. Despite decades of intensive research, the mainstay of cancer pain treatment is still non‐

Stability and Structure-Forming Properties of the Two Disulfide Bonds of α-Conotoxin GI
α-Conotoxin GI is a 13 residue snail toxin peptide cross-linked by Cys2−Cys7 and Cys3−Cys13 disulfide bridges. The formation of the two disulfide bonds by thiol/disulfide exchange with oxidized glutathione (GSSG) has been characterized.

Venom duct origins of prey capture and defensive conotoxins in piscivorous Conus striatus
The venom duct origins of predatory and defensive venoms has not been studied for hook-and-line fish hunting cone snails despite the pharmacological importance of their venoms. To better understand the biochemistry and evolution of injected predatory and
