Bestatin is widely used in biochemical and pharmacological research due to its ability to inhibit aminopeptidases, which are enzymes that play a role in protein metabolism. It is particularly studied for its potential in cancer therapy, as it can enhance the immune response by increasing the activity of natural killer cells and macrophages. Additionally, Bestatin is explored for its anti-inflammatory properties, making it a candidate for treating inflammatory diseases. In clinical settings, it has been investigated as an adjunct in chemotherapy to improve treatment outcomes by modulating immune functions. Its role in inhibiting tumor growth and metastasis is also a significant area of research, offering promising avenues for cancer treatment strategies.
