IDOi-Pt(IV) prodrug-1 (Compound 10) is an IDOi-Pt(IV) prodrug. IDOi-Pt(IV) prodrug-1 inhibits IDO expression. IDOi-Pt(IV) prodrug-1 induces apoptosis, decreases the mitochondrial membrane potential, inhibits tumor cell migration and invasion. IDOi-Pt(IV) prodrug-1 induces reactive oxygen species-mediated endoplasmic reticulum stress and secretion of damage-associated molecular patterns (DAMPs), thereby presenting immunogenic cell death (ICD) effects. IDOi-Pt(IV) prodrug-1 has high-efficiency and low-toxicity antitumor effects compared to Cisplatin with IC50 values in the range of 1.2 to 3 μM. Soclenicant can be used in studies of anxiety, trauma, and stressor-related disorders.
