Mechanism of action elucidated with Qube

Two papers were recently published mechanistic studies; in Inhibitory effects of cannabidiol on voltage-dependent sodium currents Xenon together with Simon Frasier University used temperature control on Qube to describe the potency and mechanism of cannabidiol binding to voltage-gated sodium channels. Interestingly the potency is higher at lower temperatures. In Selective Nav1.7 Antagonists with Long Residence Xenon together with Genentech describe the mechanism of several of their compounds in selectively inhibiting Nav1.7, which is relevant in relation to inflammatory and neuropathic pain. These compounds act very slowly, but Qube allows more than one hour long experiments with very good voltage control during the whole experiment or as the authors state:

“Appropriate filters for minimum seal resistance and minimum current size were applied, and series resistance was compensated >80% to yield high- quality sodium channel recordings on par with manual voltage clamp techniques”
