Background:

Cipargamin (NITD609) is an potent antimalarial compound, with IC50 of appr 1 nM against P. falciparum.

Cipargamin (NITD609) inhibits T. gondii with a MIC90 for tachyzoites of 5 μM and a MIC50 of 1 μM, without toxicity to human foreskin fibroblasts (HFFs) at the highest concentration tested (10 μM)[1]. Cipargamin (NITD609) is the most effective inhibitor of early gametocyte development at 50 and 500 nM. Cipargamin shows a dose-dependent inhibiting effect on late gametocyte development[2]. Cipargamin (NITD609) shows potent activities against a panel of culture-adapted P. falciparum strains, with ICIC50 values of 0.5-1.4 nM. Cipargamin is effective as artesunate with potency in the low nanomolar range (ICIC50 values consistently P. falciparum and P. vivax isolates[3].

Cipargamin (NITD609) shows favorable pharmacokinetic properties and displays single dose cure efficacy in a malaria mouse model. Cipargamin (100 mg/kg) completely clears P. berghei infection in all treated mice, and partial cure (50%) is achieved with a single oral dose at 30 mg/kg[3].
