DNDI-6174
Based on 1 Customer Validation
DNDI-6174 is an orally active Leishmania cytochrome b (Qi site of cytochrome bc1 complex/complex III) inhibitor. DNDI-6174 binds to the Qi site of Leishmania cytochrome b, inhibits cytochrome bc1 complex activity in the parasite's electron transport chain across promastigote and axenic amastigote stages. DNDI-6174 reduces parasite burden in rodent models, inhibits growth of various Leishmania species, drug-resistant clinical isolates, and Trypanosoma cruzi, with marginal activity against Trypanosoma brucei. DNDI-6174 can be used for the research of visceral leishmaniasis, cutaneous leishmaniasis.

Biological Activity
DNDI-6174 (96 h) potently inhibits the intracellular amastigote stage of diverse Leishmania species/strains responsible for VL and CL, including drug-resistant isolates, with EC50 values ranging from 12 nM to 740 nM[1].
DNDI-6174 (72 h) inhibits growth of wild-type L. donovani promastigotes and axenic amastigotes with EC50 values of 24 nM and 75 nM, respectively; cross-resistance with DDD01716002-resistant lines and generated DNDI-6174-resistant lines confirms targeting of the cytochrome bc1 Qi site[1].
DNDI-6174 potently inhibits cytochrome bc1 complex activity in L. donovani promastigote and axenic amastigote mitochondrial lysates, with IC50 values of 8 nM and 2 nM, respectively[1].
DNDI-6174 shows a favorable in vitro safety profile with no cytotoxicity, genotoxicity, or significant mammalian mitochondrial inhibition at relevant concentrations; it exhibits moderate CYP inhibition and specific drug transporter inhibition, and high intestinal permeability[1].

Result:Achieved >98% reduction in liver parasite burden relative to vehicle controls when dosed at 12.5 mg/kg twice daily for 5 days, 25 mg/kg once daily for 5 days, or 6.25 mg/kg twice daily for 10 days.
Reached >95% reduction in liver parasite burden in mice infected with either L. donovani or L. infantum with 5-day regimens of 12.5 mg/kg twice daily or higher.
Failed to reach >95% reduction in liver parasite burden with 6.25 mg/kg twice daily for 5 days.

Result:Achieved >99% reduction in parasite burden across liver, spleen, and bone marrow relative to vehicle controls with once daily doses of 12.5 mg/kg or higher for 5 days.
Reached >95% reduction in parasite burden with twice daily dosing at 6.25 mg/kg for 5 days.
Showed no efficacy with once daily dosing at 6.25 mg/kg for 5 days.
Resulted in almost all organs being negative for viable parasites via promastigote back-transformation assay, suggesting potential to approach sterile cure, though 2 of 5 hamsters in the highest dosing group had at least one organ positive for residual parasites.
