Guanfu base H is a diterpenoid alkaloid isolated from Aconitum coreanum. It has antiplasmodial activity against the malarial Plasmodium falciparum strains TM4 8.2 (wild type) and K1CB1 (IC50s: 4 μM and 3.6 μM).
Isochondodendrine has strong antiplasmodial activity against Plasmodium falciparum. Isochondrodendrine is a class of bisbenzylisoquinoline alkaloid isolated from Isolona ghesquiereina.
L-Canaline, a nonprotein amino acid found in many leguminous plants, exhibits potent anticancer and antiproliferative effects. It effectively inhibits the growth of the malaria parasite Plasmodium falciparum with an IC50 of 297 nM. Additionally, L-Canaline acts as a cytotoxic metabolite produced from L-canavanine through arginase catalysis and serves as a potent and irreversible inhibitor of ornithine aminotransferase.
CWHM-1008 is an effective oral antimalarial drug. The EC50 values of the drug-sensitive Plasmodium falciparum 3D7 and drug-resistant Dd2 strains are 46 and 21 nM, respectively.
