p. falciparum 3d7 parasites

DSM265 (PfSPZ) is a dihydroorotic acid dehydrogenase inhibitor with antimalarial activity (IC50: 8.9 nM).DSM265 inhibits the growth of Pf3D7 parasites and can be used for the treatment and prophylaxis of malaria infections.

DSM1465 (Compound 82) is a potent and selective inhibitor of P. falciparum dihydroorotate dehydrogenase (PfDHODH) with an IC50 value of 15 nM. It inhibits P. falciparum 3D7 (Pf3D7) parasites with an EC50 value of 1.4 nM and demonstrates significant in vivo efficacy in humanized P. falciparum mouse models.

Purfalcamine is an orally active, selective Plasmodium falciparum calcium-dependent protein kinase 1 (PfCDPK1) inhibitor with an IC50 of 17 nM and an EC50 of 230 nM, exhibiting antimalarial activity by inducing developmental arrest of malaria parasites at the schizont stage[1][2].
