These compounds inhibit the tyrosine kinase activity of the receptor for epidermal growth factor (EGF) and c-erbB2 kinase and can be used as anti-tumor agents.
(IDO) 1 is the key enzyme for regulating tryptophan metabolism and is an important target for interrupting tumor immune escape. In this study, we designed four series of compounds as potential IDO1 inhibitors by attaching various fragments or ligands to indole or phenylimidazole scaffolds to improve binding to IDO1. The compounds were synthesized and their inhibitory activities against IDO1 and tryptophan
