From Bench to Bedside: Transforming Cancer Therapy with Protease Inhibitors

Proteases play a pivotal role in cancer progression, facilitating processes such as extracellular matrix degradation, angiogenesis, and metastasis. Consequently, protease inhibitors have emerged as promising therapeutic agents in oncology. This review provides a comprehensive overview of the mechanisms by which protease inhibitors modulate cancer biology, categorizing inhibitors by their target protease classes, including matrix metalloproteinases, cysteine proteases, and serine proteases. We discuss the therapeutic potential of both synthetic and natural protease inhibitors, highlighting their applications in preclinical and clinical settings. Furthermore, challenges such as specificity, toxicity, and resistance mechanisms are addressed, alongside strategies to overcome these limitations through innovative drug designs and combination therapies. The future of protease inhibitors in cancer treatment lies in precision medicine, leveraging proteomic profiling to tailor therapies to individual tumors. This review underscores the importance of ongoing research and the development of novel approaches to harness protease inhibitors effectively for cancer management.
