Incyclinide is primarily investigated for its potential therapeutic applications in the treatment of various types of cancer. It functions as a matrix metalloproteinase (MMP) inhibitor, targeting enzymes that play a role in tumor growth, invasion, and metastasis. By inhibiting these enzymes, it may help slow the progression of cancer and reduce the spread of malignant cells to other parts of the body. Research has explored its use in cancers such as breast, prostate, and lung cancer, where MMP activity is often elevated. Additionally, it has been studied in combination with other anticancer therapies to enhance their effectiveness. While still under clinical investigation, its potential to improve outcomes in cancer treatment makes it a promising candidate for further development.
