Used in traditional medicine for its cardiotonic effects, acetylarenobufagin exhibits potent activity on heart muscle contraction. It has been studied for its ability to inhibit Na+/K+-ATPase, which contributes to its positive inotropic effect, making it relevant in research on heart failure treatments. Additionally, it shows antitumor potential in some cancer cell lines, prompting interest in oncology-related drug development. Due to its high toxicity, it is primarily used in controlled research settings rather than clinical applications.
