Biochem/physiol Actions

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.

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

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

Diarrhoeal disease is responsible for 8.6% of global child mortality. Recent epidemiological studies found the protozoan parasite Cryptosporidium to be a leading cause of paediatric diarrhoea, with particularly grave impact on infants and immunocompromised individuals. There is neither a vaccine

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

Scientific reports, 7(1), 17680-17680 (2017-12-17)
Eradication of malaria requires a novel type of drug that blocks transmission from the human to the mosquito host, but selection of such a drug is hampered by a lack of translational models. Experimental mosquito infections yield infection intensities that
