Used in biological research, particularly in studies of the potassium ion channel (Kv1.3), which is involved in the function of T cells in the immune system. BF-170 hydrochloride acts as an inhibitor of this ion channel, enabling effective studies of chronic inflammation and autoimmune diseases such as rheumatoid arthritis and type 1 diabetes. Additionally, it aids in the development of new drugs targeting the control of immune responses without reducing overall immunity.
