Used in research settings to investigate inflammatory and autoimmune diseases due to its potent inhibition of spleen tyrosine kinase (Syk). It shows promise in modulating immune cell signaling, particularly in B cells and Fc receptor pathways, making it a candidate for studying conditions like rheumatoid arthritis, lupus, and allergic responses. Its selectivity allows for targeted exploration of Syk-dependent mechanisms without broad immunosuppression. Often utilized in preclinical models to assess therapeutic potential and mechanism of action in immune-mediated disorders.
