Design, Synthesis, and Structural Evolution of Pseudo-Natural Product IDO1 Inhibitors and Degraders. [PDF]
Angew Chem Int Ed EnglThe combination of bicyclic monoterpene‐ and pyrrolidine‐alkaloid fragments yields novel pseudo‐natural products. Biological characterization revealed that these iDegs are inhibitors and degraders of indoleamine‐2,3‐dioxygenase. Abstract Terpenoid alkaloids are derived from the fusion of structurally diverse terpenoid‐ and alkaloid moieties.
