This book draws together contributions from basic, pharmaceutical
and clinical sciences aimed at a better understanding of the
structure and function of h ERG and the molecular basis for compound
binding.
It features regulatory authority perspectives on preferred
preclinical test systems and includes topics on h ERG channel
gating, regulation of functional expression, pharmacological
properties of h ERG/IKr channels, drug-induced long QT syndrome and
preclinical evaluation and regulatory recommendations for assessing
QT prolongation risks.
Better understanding of the role of the h ERG channel in
drug-induced cardiac arrhythmias should ultimately lead to the
development of important, new and safer medicines.
