Herein we report the first exploration of a dual‐targeting drug design strategy to improve the efficacy of small‐molecule cancerimmunotherapy. New hybrids of indoleamine 2,3‐dioxygenase 1 (IDO1) inhibitors and DNA alkylating nitrogen mustards that respectively targetIDO1 and DNA were rationally designed. As the first‐in‐class examples of such molecules, they were found to exhibit significantly enhanced

The present invention relates to an indoleamine 2,3-dioxygenase inhibitor having the structure of formula (I), a preparation method therefor, and an application. The IDO inhibitor is an N′-hydroxyl-N-phenylformamidine derivative, which has a high inhibitory activity on IDO, effectively inhibits IDO activity, and may also be used to inhibit patient immunosuppression. The inhibitor may be widely applied to treat or prevent cancers or tumors, viral infections, depression, neurodegenerative disorders, trauma, age-related cataracts, organ transplant rejection or autoimmune diseases, and has the potential to be developed into a new generation of immunosuppressors.

In some embodiments, the methods involve the use of a combination of at least two of the following: an inhibitor of indoleamine-2,3-dioxygenase (IDO), an inhibitor of the PD-L1/PD-1 pathway, an inhibitor of CTLA-4, an inhibitor of CD25, or IL-7. The inventors particularly observed a major synergistic effect of combining anti-CTLA-4 with either an IDO inhibitor, with anti-PD-L1 mAb, or with CD-25 depletion. Such combinations have been found to demonstrate a synergistic effect in treating cancer and tumors, for example by reducing tumor size, increasing the percentage of antigen-specific T cells, and increasing T cell function.
