• Hepatic stage parasites represent further complication for and infections, as some of the parasites in the hepatocytes transform into hypnozoites, which can stay dormant up to several years and cause relapse.4 A few medicines, e.g. atovaquone and 8-aminoquinolines primaquine and tafenoquine are effective against LS, but the primaquine is the only FDA licensed drug. (exposed-skin-care.net)
  • Primaquine is also harmful and has a very short half-life.4 Many other non-8-aminoquinolines lack oral bioavailability, and a few natural products with anti-LS activity have low selectivity.5,6 Hence, the search for new organic or synthtetic medicines focusing on the LS of the malaria parasite is timely and necessary.
