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 [3,9] and awarded MMV Project of the Year (2009).
The active enantiomer is shown here, with the 1R,3S configuration essential for antimalarial activity [3].
