P32/98 is primarily used in biochemical research as a selective inhibitor of dipeptidyl peptidase IV (DPP-IV), an enzyme involved in various physiological processes. Its application is significant in studying glucose metabolism and the regulation of insulin secretion, making it a valuable tool in diabetes research. By inhibiting DPP-IV, P32/98 helps researchers understand the role of this enzyme in the degradation of incretin hormones, which are crucial for maintaining glucose homeostasis. Additionally, it is utilized in the development of therapeutic strategies for type 2 diabetes, as DPP-IV inhibitors are a class of drugs used to improve glycemic control. Beyond diabetes research, P32/98 is also employed in studies related to immune regulation and cancer, where DPP-IV activity plays a role in modulating cell signaling and proliferation. Its specificity and efficacy make it a key compound in both basic and applied biomedical research.
