Tanomastat is primarily used in research and clinical studies focused on cancer treatment. It functions as a matrix metalloproteinase (MMP) inhibitor, which helps in controlling the spread of cancer cells by inhibiting enzymes that degrade the extracellular matrix. This action is crucial in preventing tumor growth and metastasis. Additionally, Tanomastat has been explored for its potential in treating inflammatory diseases and conditions involving tissue remodeling, such as arthritis and cardiovascular diseases. Its ability to modulate MMP activity makes it a valuable compound in developing therapeutic strategies for these complex medical conditions.
