SKF 38393 is primarily used in research settings to study the dopamine system, particularly the D1 dopamine receptor. It acts as a selective agonist for the D1 receptor, making it a valuable tool in neuroscience and pharmacology. Researchers use it to explore the role of D1 receptors in various physiological and behavioral processes, such as motor control, cognition, and reward mechanisms. It is also employed in studies investigating conditions like Parkinson's disease, schizophrenia, and addiction, as it helps to elucidate the specific contributions of D1 receptor activation in these disorders. Additionally, SKF 38393 is used in experimental models to understand the signaling pathways and molecular mechanisms associated with dopamine receptor activity.
