WebOne of the most well-known anti-targets defining medication cardiotoxicity is the voltage-dependent hERG K + channel, which is well-known for its crucial involvement in cardiac action potential repolarization. Torsades de Pointes, QT prolongation, and sudden death are all caused by hERG (the human Ether-à-go-go-Related Gene) inhibition. There is great … WebAs shown in Figure 4 A, the shape of the hERG current under an action potential (AP) waveform voltage-clamp protocol in the dynamic hERG model is close to that of IKr in the original ORd model.

WebJan 28, 2014 · Whilst obtaining an IC50 for drug block of hERG is relatively straight forward, this is a poor surrogate for risk of pro-arrhythmia. Predicting the overall consequences of hERG drug block on cardiac electrical activity is complicated by the fact that the effect of hERG channel block varies in different cells (e.g. epicardial, mid-myocardial, … WebNov 4, 2024 · In this work, we emphasize the need for human-relevant hERG safety prediction and mitigation criteria during the preclinical stages of drug discovery, … WebMar 27, 2024 · A novel hERG/IKr dynamic model was developed by combining a Markov model of the hERG channel that includes temperature-sensitive gating pharmacological components representing open (IO, O) or closed (IC1, IC2, C1, C2) state of hERG channel and a pharmacodynamic model applying drug binding (IO * and O *) and trapping (C *) … roche posay effac sch rein
