IID432
Based on 1 Customer Validation
IID432 is a potent, orally active, and covalent inhibitor of Trypanosoma cruzi topoisomerase II. IID432 shows an EC50 of 8 nM against T. cruzi intracellular amastigotes, exhibits excellent oral bioavailability (52% in rats), favorable ADME properties, and no S1P pathway modulation. IID432 achieves relapse-free cure in a chronic T. cruzi infection mouse model, can be used for the study of Chagas disease.

Topoisomerase II |
IID432 (6 days) inhibits the growth of intracellular T. cruzi amastigotes in T. cruzi-infected NIH 3T3 fibroblasts with an EC50 of 8 nM[1].
IID432 (4 days) displays no cytotoxicity toward NIH 3T3 fibroblasts (CC50 > 20 μM)[1].
IID432 exhibits decreased potency against CRISPR-generated topoisomerase II mutant strains of T. brucei (>150-fold) relative to wild-type parasites[1].
IID432 (10 μM; 24 h) does not significantly increase intracellular sphingosine-1-phosphate (S1P) levels in HEK293T cells (1.2-fold increase) compared to DMSO control[1].

IID432 (25 mg/kg; p.o.; single dose) fully eliminates parasites in all treated animals in a chronic T. cruzi infection model in BALB/c mice (~100 days post-infection), with no detectable parasites after cyclophosphamide-induced immunosuppression (3 rounds at days 112, 116, and 120 post-treatment)[1].
IID432 (30 mg/kg/day; p.o.; once daily for 14 days) does not trigger S1P accumulation in the kidney or spleen relative to vehicle in Wistar rats, and maintains hematological parameters within the normal range[1].
IID432 (up to 50 mg/kg/day; p.o.; once daily for 14 days) is well tolerated in nonhuman primates with no significant adverse effects[1].
