Example text

1 Overview of drugs often cited in the text. Low-affinity transporter AT1 [46], most likely high-affinity AQP2 [108, 109] Low-affinity transporter AT1 [46], most likely high-affinity AQP2 [108, 109] Transported through LdMT [71], if in the presence of LdRos3 [72] Entrance through AAT6 [55] Possibly through TcABCG1 [100] PfCTR, probably in vacuoles [63, 64] Entrance through AQP1 [80]; export through PGPA [98] Genes implicated in mode of entrance Activated by type 1 NTR [57]; probably causes oxidative stress ; possibly DNA/RNA degradation [112] Mechanism unclear; cross-resistance with Melarsoprol [47] Probably several activity, among them increased oxidative stress [110, 111] SbV is reduced to SbIII [76–78]; nonspecific toxicity Targets phosphatidylinositol-3-kinase [105]; resistance can be cause by mutation in Kelch-13 propeller [104] Inhibits cytochrome b/c [106] Activated by type 1 NTR [57]; probably causes oxidative stress [107] Probably inhibiting hemozoin formation [37, 38]; PfMDR1 is involved in resistance [64] It targets and covalently binds ornithine decarboxylase [50] Mechanism unclear; cross-resistance with Pentamidine [47] Genes implicated in mode of action and resistance Principles 5 6 1 Discovery the Mechanism of Action Growth, morphology Target organelle/structure?

Five metabolites in this pathway were quantified, and it was found that in fact another enzyme, methylerythritol phosphate cytidylyltransferase, was inhibited [177]. This result prompted further investigation, and indeed, overexpression of methylerythritol phosphate cytidylyltransferase conferred resistance to fosmidomycin [177]. If drug targets are not known, untargeted metabolomics can be used to identify candidate target pathways [167]. Taking samples at different times is important to characterize the drug effect and use of different drug combinations can also be informative.

The authors validated the interaction of this compound with adenosine kinase using circular dichroism spectroscopy and isothermal titration calorimetry, based on the principle that a protein binding to its ligand will have higher thermal stability [142]. The substrate transformation kinetics indicated that the compound was limiting the substrate inactivation pathway. The authors speculated that the parasites died because deregulation of the enzyme activity disrupted purine interconversion [142].
