Abstract

Compounds that modulate the oxidoreductase enzyme indoleamine 2,3- dioxygenase, and compositions containing the compounds, are described herein. The use of such compounds and compositions for the treatment and / or prevention of a diverse array of diseases, disorders and conditions, including cancer- and immune-related disorders, that are mediated by indoleamine 2,3-dioxygenase is also provided.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to U.S. Provisional Application Nos. 62 / 075,671, filed November 5, 2014, and 62 / 098,022, filed December 30, 2014, respectively, the entire contents of which applications are incorporated herein by reference middle. Background of the invention [0003] Indoleamine 2,3-dioxygenase (IDO; also known as IDO1) is an IFN-γ target gene that plays a role in immune regulation. IDO is an oxidoreductase and is one of two enzymes that catalyze the first and rate-limiting step in the conversion of tryptophan to N-formyl-kynurenine. It exists as a 41 kD monomer found in several cell populations including immune cells, endothelial cells and fibroblasts. IDO is relatively well conserved between species, with mice and humans sharing 63% sequence identity at the amino acid level. Data derived from its crystal structure and site-directed mutagenesis show that substrate binding and the relationship between...
