IDO1-IN-19(Cat No.:I043713)is a potent and selective inhibitor of indoleamine 2,3-dioxygenase 1 (IDO1), an enzyme that plays a key role in immune suppression by degrading tryptophan. By inhibiting IDO1, IDO1-IN-19 can restore immune function and enhance anti-tumor immunity, making it a promising candidate for cancer immunotherapy. It also holds potential for treating autoimmune diseases and chronic infections by modulating the immune response. With its high specificity and efficacy, IDO1-IN-19 is a valuable tool for researchers investigating immune regulation and developing targeted therapies in oncology and immunology.
