Used in pharmaceutical research as a key intermediate in the synthesis of kinase inhibitors, particularly targeting cancer-related enzymes such as Aurora kinases and cyclin-dependent kinases (CDKs). Its structure supports the development of anti-proliferative agents due to its ability to mimic natural indole-containing compounds involved in cell signaling. Also explored in the design of anti-inflammatory and neuroprotective drugs owing to the indole scaffold’s biological relevance. Serves as a building block in medicinal chemistry for constructing more complex heterocyclic systems through Michael addition or cyclization reactions.
