Journal Article
Amey, J. S., O'Reilly, A. O., Burton, M. J., Puinean, A. M., Mellor, I. R., Duce, I. R., …Davies, T. E. (2015). An evolutionarily-unique heterodimeric voltage-gated cation channel found in aphids. FEBS Letters, 589(5), 598-607. https://doi.org/10.1016/j.febslet.2015.01.020

We describe the identification in aphids of a unique heterodimeric voltage-gated sodium channel which has an atypical ion selectivity filter and, unusually for insect channels, is highly insensitive to tetrodotoxin. We demonstrate that this channel h... Read More about An evolutionarily-unique heterodimeric voltage-gated cation channel found in aphids.

The Aryl hydrocarbon receptor (AhR) binds a variety of chlorinated and brominated dioxins, furans and biphenyls. Mixed halogenated variants have been recently identified in food at significant levels but full characterisation requires potency data in...

Philanthotoxin?433 (PhTX?433) is a known potent inhibitor of ionotropic glutamate receptors, and analogues have been synthesised to identify more potent and selective antagonists. Herein we report the synthesis of four PhTXs with a cyclopropane moiet... Read More about The Effects of Conformational Constraints in the Polyamine Moiety of Philanthotoxins on AMPAR Inhibition.

The mechanisms regulating the induction of hepatic DNA synthesis by PPARα agonists are currently incompletely understood, and we set out to determine whether there are different mechanisms of induction for PPARα agonists and other hepatic growth agen...

The antimalarial drug quinine interferes with serotonin biosynthesis and action (2014)
Journal Article
Islahudin, F., Tindall, S. M., Mellor, I. R., Swift, K., Christensen, H. E., Fone, K. C., …Avery, S. V. (2014). The antimalarial drug quinine interferes with serotonin biosynthesis and action. Scientific Reports, 4(3618), https://doi.org/10.1038/srep03618

The major antimalarial drug quinine perturbs uptake of the essential amino acid tryptophan, and patients with low plasma tryptophan are predisposed to adverse quinine reactions; symptoms of which are similar to indications of tryptophan depletion. As... Read More about The antimalarial drug quinine interferes with serotonin biosynthesis and action.

The bivalent ligand approach as a tool for improving the in vitro anti-alzheimer multitarget profile of dimebon (2013)
Journal Article

Inspired by the concept of bivalent ligands, we prepared a small set of analogues of the drug candidate dimebon. They were shown to inhibit AChE, Aβ42 aggregation, and NMDA receptor activation to a greater extent than dimebon. Some of these compounds...
