Used in research settings as a selective inhibitor of protein-protein interactions, particularly in studies involving apoptosis and cancer pathways. It helps modulate the activity of Bcl-2 family proteins, making it a tool compound for investigating cell survival and death mechanisms. Due to its ability to disrupt anti-apoptotic signaling, it has been explored for potential use in developing anticancer therapies, especially in combination with other pro-apoptotic agents. Its racemic nature requires careful evaluation in biological assays to distinguish the activity of individual enantiomers.
