Elucidating The Mechanism Of Antimigratory Activity Of Cardiac Glycosides, Joshua H. Johnson

Honors Scholar Theses

The focus of this research is on cell migration and how it can be better understood through the use of small molecules that modulate cell migratory activity. The results have particular relevance in the realm of cancer pharmacology. Cardiac glycosides, which are known inhibitors of the eukaryotic Na⁺/K⁺-ATPase, have been determined to have antimigratory activities through the screening of several small molecule libraries. Here we investigate the antimigratory activities of the cardiac glycoside digitoxin as well as its analogs that we synthesized. Antimigratory activity was determined by conducting a wound closure assay with MDA-MB-231 human breast …
