N-Phenethylbiguanide is primarily recognized for its role in the treatment of type 2 diabetes. It functions by decreasing glucose production in the liver, enhancing insulin sensitivity, and improving glucose uptake by muscle tissues. This helps in maintaining blood sugar levels within a normal range, making it a valuable component in diabetes management. Additionally, it has been explored for its potential anti-cancer properties, where it may inhibit the growth of certain cancer cells by affecting their metabolism. Research is ongoing to further understand and harness its therapeutic benefits in oncology. Its application extends to studies in metabolic disorders, where it aids in understanding the mechanisms of glucose regulation and insulin resistance.
