Results of a Phase 1 Study Assessing the Effect of CIN‐102, a Novel Formulation of the Dopamine Receptor Antagonist Domperidone Designed to Treat Gastroparesis, on Cardiac Repolarization in Healthy Volunteers

Clinical Pharmacology in Drug Development, Volume 15, Issue 3, March 2026.
Abstract CIN‐102 is a deuterated form of domperidone in development for the treatment of acute, recurrent gastroparesis. This thorough QT study assessed the effects of CIN‐102 on cardiac repolarization in 62 healthy volunteers. In this 4‐period randomized crossover study, participants were administered single doses of 30‐mg CIN‐102 (representing ...

AttenhERG: a reliable and interpretable graph neural network framework for predicting hERG channel blockers

Journal of Cheminformatics
Cardiotoxicity, particularly drug-induced arrhythmias, poses a significant challenge in drug development, highlighting the importance of early-stage prediction of human ether-a-go-go-related gene (hERG) toxicity.

Plectasin, First Animal Toxin-Like Fungal Defensin Blocking Potassium Channels through Recognizing Channel Pore Region

Toxins, 2015
The potassium channels were recently found to be inhibited by animal toxin-like human β-defensin 2 (hBD2), the first defensin blocker of potassium channels. Whether there are other defensin blockers from different organisms remains an open question. Here,

Position of Premature Termination Codons Determines Susceptibility of hERG Mutations to Nonsense-Mediated mRNA Decay in Long QT Syndrome

, 2014
The degradation of human ether-a-go-go-related gene (hERG, KCNH2) transcripts containing premature termination codon (PTC)mutations by nonsense-mediatedmRNA decay (NMD) is an importantmechanismof long QT syndrome type 2 (LQT2).

Congenital Long QT Syndrome: An Update and Present Perspective in Saudi Arabia [PDF]

, 2013
Primary cardiac arrhythmias are often caused by defects, predominantly in the genes responsible for generation of cardiac electrical potential, i.e., cardiac rhythm generation.

Hydroxyzine, a First Generation H1-Receptor Antagonist, Inhibits Human Ether-a-go-go–Related Gene (HERG) Current and Causes Syncope in a Patient With the HERG Mutation

Journal of Pharmacological Sciences, 2008
QT prolongation, a risk factor for arrhythmias, can result from genetic variants in one (or more) of the genes governing cardiac repolarization as well as intake of drugs known to affect a cardiac K+ channel encoded by human ether-a-go-go–related gene ...

The conduction pore of a cardiac potassium channel. [PDF]

, 1998
Ion channels form transmembrane water-filled pores that allow ions to cross membranes in a rapid and selective fashion. The amino acid residues that line these pores have been sought to reveal the mechanisms of ion conduction and selectivity. The pore (P)

hERG channel agonist NS1643 strongly inhibits invasive astrocytoma cell line SMA-560.

PLoS ONE
Gliomas are highly malignant brain tumours that remain refractory to treatment. Treatment is typically surgical intervention followed by concomitant temozolomide and radiotherapy; however patient prognosis remains poor.

Experimentally Validated Pharmacoinformatics Approach to Predict hERG Inhibition Potential of New Chemical Entities

Frontiers in Pharmacology, 2018
The hERG (human ether-a-go-go-related gene) encoded potassium ion (K+) channel plays a major role in cardiac repolarization. Drug-induced blockade of hERG has been a major cause of potentially lethal ventricular tachycardia termed Torsades de Pointes ...
