KDU691 is an orally active imidazopyrazine class antiparasitic that inhibits Plasmodium & Cryptosporidium phosphatidylinositol-4-OH kinase, PI(4)K, in an ATP-competitive, highly potent and selective manner (IC50/[ATP] = 1.5 nM/10 μM/P. vivax & 17 nM/3 μM/C. parvum PI(4)K) with little or no activity against human PI3Kα/β/γ/δ, PI4KIIIβ, VPS34, and 36 human protein kinases. KDU691 is effective against human pathogens P. falciparum, P. vivax, C. parvum and C. hominis, as well as simian parasite P. cynomolgi. KDU691 blocks Plasmodium development in all life-cycle stages and displays in vivo efficacy in murine models of malaria and cryptosporidiosis.

To develop new drugs and vaccines for malaria elimination, it will be necessary to discover biological interventions, including small molecules that act against Plasmodium vivax exoerythrocytic forms. However, a robust in vitro culture system for P. vivax is still lacking. Thus...

A molecular understanding of drug resistance mechanisms enables surveillance of the effectiveness of new antimicrobial therapies during development and deployment in the field. We used conventional drug resistance selection as well as a regime of limiting dilution at early stages...

The unique relapsing nature of Plasmodium vivax infection is a major barrier to malaria eradication. Upon infection, dormant liver-stage forms, hypnozoites, linger for weeks to months and then relapse to cause recurrent blood-stage infection. Very little is known about hypnozoite...

Two Plasmodium PI4 kinase (PI4K) inhibitors, KDU691 and LMV599, were selected for in vivo testing as causal prophylactic and radical-cure agents for Plasmodium cynomolgi sporozoite-infected rhesus macaques, based on their in vitro activity against liver stages. Animals were infected with...

Artemisinin (ART) resistance has spread through Southeast Asia, posing a serious threat to the control and elimination of malaria. ART resistance has been associated with mutations in the Plasmodium falciparum kelch-13 (Pfk13) propeller domain. Phenotypically, ART resistance is defined as...
