Twelve new peer-reviewed publications using QPatch or Qube 384 in Q3

̶T̶w̶e̶l̶v̶e̶ thirteen new peer-reviewed publications were published in Q3 using QPatch or Qube 384.

Most of the publications this quarter came from the pharma industry, with publications from Gedeon Richter, Eisai, Lundbeck, Sanofi, Novartis, Esteve, Taisho Pharmaceuticals. However, as always, a few from academia with one from University of Heidelberg using Qube 384 and also, as always, a massive input from the University of Queensland with four publications. To our knowledge that brings the University of Queensland up to 12 publications using QPatch in 2020 alone.

NMDA, Cav3.X, the full sodium channel panel Nav1-8 and the entire CiPA safety panel have been investigated. Also, a few of the QPatch publications were only used for hERG safety testing. While this might be of less scientific relevance it is great to see that the QPatch still are the benchmark for cardiac safety testing and hERG counter screens.

Topics are diverse, from NMDA research to early drug discovery and lead optimisation.

Of the more exotic topics, we could highlight Wang er al 2020 and McMahon et al. 2020 using QPatch to characterise the effect of conotoxins, a group of neurotoxic peptides isolated from the venom of the predatory marine cone snails of the genus Conus.

Le Marois et al. 2020 might be a good evening read. This group at Sanofi in Paris, France, has evaluated the effect of the non-psychoactive component of Cannabis (CBD) on seven major cardiac currents. They show that CBD impacts cardiac electrophysiology, so hold back on the cannabis oil if you have heart problems.

Enjoy the read, and remember you can always find QPatch and Qube 384 publications on in our publication library
