IDOi-Pt(IV) prodrug-1 (Compound 10) is an IDOi-Pt(IV) prodrug that suppresses IDO expression. It induces apoptosis, reduces mitochondrial membrane potential, and inhibits tumor cell migration and invasion. Additionally, IDOi-Pt(IV) prodrug-1 triggers reactive oxygen species-mediated endoplasmic reticulum stress and the secretion of damage-associated molecular patterns (DAMPs), leading to immunogenic cell death (ICD). Compared to cisplatin, IDOi-Pt(IV) prodrug-1 exhibits relatively high efficiency and low toxicity in its antitumor activity.

Benzomalvin C is a weak antagonist of the neurokinin-1 (NK1) receptor, inhibiting binding of substance P by 46% at 100 μg ml in vitro, and a weak inhibitor of indolamine 2,3-dioxygenase (IDO) with an IC50 value of 130 μM for recombinant IDO. Isolated from Penicillium, it contains an epoxide group at C-19 and C-20, absent in benzomalvins A, B, or E.

Acid secretion-IN-1, a polycyclic compound, is synthesized for its application as an IDO inhibitor in synthetic experiments.

IDO1-IN-11 is an IDO1 inhibitor with an IC50 value of 0.6 nM.

IDO1-IN-7, a potent and selective indoleamine-2,3-dioxygenase-1 (IDO1) inhibitor, exhibits high potency with an IC 50 of 6.1 nM in the cellular assay (SKOV3). Apart from its inhibitory properties, IDO1-IN-7 also demonstrates immunomodulatory effects, contributing to its potential applications in cancer research.

IDO1-IN-12 is a potent oral inhibitor of IDO1 (indoleamine 2,3-dioxygenase 1).

eIF4E-IN-1 (WO2021003194A1, compound Y), is a highly effective inhibitor of eIF4E, a key protein involved in immunosuppression. By targeting immune checkpoint proteins such as PD-1, PD-L1, LAG3, TIM3, and IDO, eIF4E-IN-1 functions to disrupt immune suppression and promote immune release in specific diseases such as cancer and infectious diseases.

PCC0208009 (IDO-IN-2) is an IDO inhibitor.

1. Coptisine sulfate has growth inhibitory activity against human cancer cell line in the NCI's anticancer drug screening program.

1. Coptisine (Coptisin) treatment increases cell viability based on its reversal effect on the enhanced activity of Indoleamine 2, 3-dioxygenase . 2. Coptisine treats myocardial I R likely through suppressing myocardial apoptosis and inflammation by inhibiting the Rho ROCK pathway. 3. Coptisine is a potential anti-osteosarcoma drug candidate, via exerting a strong anti-osteosarcoma effect with very low toxicity . 4. Coptisine with a high dosage could inhibit cholesterol synthesis via suppressing the HMGCR expression and promoting the use and excretion of cholesterol via up-regulating LDLR and CYP7A1 expression. 5.
