Neurotoxicological effects now rank second behind cardiovascular events as adverse events impeding the development and safety of new drug candidates. Accordingly, Metrion has developed assays that can be used to predict seizurogenic and neurotoxic compound activity in the peripheral and central nervous system using native neurons, and are now building similar assays with human stem-cell derived neurons. Both approaches provide a translational step for development of anticonvulsant compounds and safe and effective treatments for other central nervous system diseases.
We developed a high-throughput, electrophysiological assay of TREK-1 function to identify novel modulators. The assay was optimized to identify both activators and inhibitors, providing comprehensive mechanistic data for high value, limited supply screening libraries, such as the venom fraction library used in this study (Targeted Venom Discovery Array, T-VDA, Venomtech, UK).
Scientifica’s PatchScope Pro is an integrated electrophysiology rig incorporating an inverted phase-contrast fluorescence microscope, motorised XY stage and PatchStar micromanipulators, suitable for patch-clamp recording.
