The electrophysiological patch clamp technique is the most direct method to show effects of drugs on ion channels in the cell membrane, and as such it remains essential as a secondary screen to the fluorescence assay. Furthermore, screening by patch clamp may be the first choice for ion channel targets, as it is the only useful technique for use-dependent drug-channel interactions. Currently Newron has a specialized Laboratory for Electrophysiological evaluations, including a TEVC platform for High Throughput Screening and patch clamp instruments.
Electrophysiological screening is conducted early in the Company's Discovery process and allows to cost-effectively decide whether or not to advance a drug candidate, as it allows to select state and frequency dependant blockers, with improved safety and tolerability profiles.
