Piperaquine Description

Piperaquine is an antiparasitic drug used in combination with dihydroartemisinin to treat malaria. It is a bis-quinoline compound that inhibits the vitro growth of P. falciparum isolates from malaria-infected patients with IC50s ranging from 11.8-217.3 nM. Piperaquine was developed under the Chinese National Malaria Elimination Programme in the 1960s and was adopted throughout China as a replacement for the structurually similar antimalarial drug chloroquine.

Piperazine phosphate has also recently become a potential drug against COVID-19.
