GtoPdb Ligand ID: 9721

Synonyms: KAE609 | NITD609
Antimalarial Ligand
Compound class: Synthetic organic
Comment: Cipargamin is an antimalarial drug candidate, under clinical development. It is the optimised lead for the spiroindolones, a novel class of compounds identified from a phenotypic screen as having antimalarial activity [2,7] and awarded MMV Project of the Year (2009).
The active enantiomer is shown here, with the 1R,3S configuration essential for antimalarial activity [2].

Guide to Malaria Pharmacology Comments
Cipargamin has potent activity against the asexual blood stages of P. falciparum and P. vivax [2] and potential as a transmission-blocking therapy with a study reporting that the drug inhibits gametocytogenesis and blocks P. falciparum transmission to the Anopheles mosquito vector [5].

Potential Target/Mechanism Of Action: A number of studies have investigated the mechanism of action of cipargamin, with evidence from genetic experiments indicating Plasmodium non-SERCA-type Ca2+-transporting P-ATPase (PfATP4) may be the target [1-2].
