1. Palmatine (Burasaine) is an inhibitor of dopamine generation. 2. Palmatine could potentially be developed for the treatment of flavivirus infections. 3. Palmatine has been used in the treatment of jaundice, dysentery, hypertension, inflammation, and liver-related diseases.

Indoximod (NLG-8189) is a methylated tryptophan with immune checkpoint inhibitory activity. Indoximod inhibits the enzyme indoleamine 2, 3-dioxygenase (IDO), which degrades the essential amino acid tryptophan, and may increase or maintain tryptophan levels important to T cell function. Tryptophan depletion is associated with immunosuppression involving T cell arrest and anergy.
