L-Alanosine is primarily used in research settings to study its effects on cancer cells due to its ability to inhibit purine biosynthesis. It has been investigated for its potential as an anticancer agent, particularly in targeting tumors that rely heavily on de novo purine synthesis. Additionally, L-Alanosine has been explored in studies related to immunosuppression, as it can interfere with the proliferation of immune cells. Its role in metabolic pathways also makes it a valuable tool in biochemical research to understand purine metabolism and its dysregulation in diseases.
