PKC-iota inhibitor 1 is primarily used in research settings to study the role of protein kinase C iota (PKC-ι) in cellular processes. It is particularly valuable in cancer research, as PKC-ι is often overexpressed in various cancers and plays a role in tumor cell survival, proliferation, and invasion. By inhibiting PKC-ι, this compound helps researchers understand its signaling pathways and its potential as a therapeutic target for cancer treatment. Additionally, it is utilized in studies focused on cell polarity and migration, which are critical in both normal development and disease progression. Its application extends to exploring the involvement of PKC-ι in inflammatory diseases and neurological disorders, providing insights into potential treatment strategies.
