Definitions
- the subject of the invention is the use of derivatives of 7H-indazole-3-carboxamides, and their pharmaceutically acceptable salts, for the preparation of a medicament for the treatment and prevention of malaria.
- Malaria is a parasitic disease transmitted by anopheles mosquitoes. This disease represents a major public health problem, with 300 to 500 million people infected and 2.7 million deaths each year, mostly children. Although eradicated in many regions of the world, malaria continues to progress endemically in Africa, Southeast Asia and South America, notably due to the parasite's resistance to certain molecules used as medicines antimalarials, especially against chloroquine which has long been the most used molecule.
- Plasmodium falciparum causes the deadly forms of the disease.
