摘要

Purine-based analogs of SDZ 211-500 (5) were prepared and evaluated as inactivation modifiers of guinea pig or human cardiac sodium (Na) channels expressed inXenopus oocytes. Substances which remove or slow the Na channel inactivation process in cardiac tissue are anticipated to prolong the effective refractory period and increase inotropy and thus have potential utility as antiarrhythmic agents. Heterocyclic substitution at the 6- ...
