Targeting protein kinases in the malaria parasite: update of an antimalarial drug targetVeronica M Zhang
Australian Army Malaria Institute, Gallipoli Barracks, Enoggera, QLD
Curr Top Med Chem 12:456-72. 2012..As the search for novel antimalarials continues, an understanding of the phosphor-regulatory pathways will not only validate protein kinase targets, but also will identify novel chemotypes to thwart malaria drug resistance...

Infect Disord Drug Targets 10:134-46. 2010..With wide spread malaria drug resistance, coupled by a parasite that can develop resistance quickly to new drugs, the development of multi-kinase inhibitors may be extremely efficacious and reduce the likelihood for resistance...
Selective inhibition of Pfmrk, a Plasmodium falciparum CDK, by antimalarial 1,3-diaryl-2-propenonesJeanne A Geyer
Division of Experimental Therapeutics, Walter Reed Army Institute of Research, Silver Spring, MD 20910, United States
Bioorg Med Chem Lett 19:1982-5. 2009..Several mechanisms of action have been suggested for chalcone derivatives and our study suggests that kinase inhibition may be an additional mechanism of antimalarial activity for this class of compounds...
A three-dimensional in silico pharmacophore model for inhibition of Plasmodium falciparum cyclin-dependent kinases and discovery of different classes of novel Pfmrk specific inhibitorsApurba K Bhattacharjee
Division of Experimental Therapeutics, Walter Reed Army Institute of Research, Silver Spring, Maryland 20910 7500, USA
J Med Chem 47:5418-26. 2004..The predicted inhibitory activities of some of these Pfmrk inhibitors from the molecular model agree exceptionally well with the experimental inhibitory values from the in vitro CDK assay...
Assessment of malaria in vitro drug combination screening and mixed-strain infections using the malaria Sybr green I-based fluorescence assayEdgie Mark A Co
Division of Experimental Therapeutics, Walter Reed Army Institute of Research, Silver Spring, MD 20910, USA
Antimicrob Agents Chemother 53:2557-63. 2009..In conclusion, the MSF assay allows for reliable antimalarial drug combination screening and provides an important method to discern between homogenous and heterogeneous parasite populations...
Evaluation of broad spectrum protein kinase inhibitors to probe the architecture of the malarial cyclin dependent protein kinase PfmrkCassandra L Woodard
Division of Experimental Therapeutics, Walter Reed Army Institute of Research, Silver Spring, MD 20910, USA
Bioorg Med Chem Lett 17:4961-6. 2007..Structural analysis suggests that even subtle differences in amino acid composition within the active sites are responsible for conferring specificity of these inhibitors for Pfmrk over PKA...
Identification of an effector protein and gain-of-function mutants that activate Pfmrk, a malarial cyclin-dependent protein kinaseYueqin Chen
Department of Parasitology, Division of Experimental Therapeutics, Walter Reed Army Institute of Research, 503 Robert Grant Avenue, Silver Spring, MD 20910, USA
Mol Biochem Parasitol 149:48-57. 2006..Significant kinase activity of these mutants was observed in the absence of either cyclin or PfMAT1. Finally, we observed autophosphorylation of Pfmrk that is unaffected by the addition of either cyclin or PfMAT1...
The malarial CDK Pfmrk and its effector PfMAT1 phosphorylate DNA replication proteins and co-localize in the nucleusDayadevi Jirage
Division of Experimental Therapeutics, Walter Reed Army Institute of Research, Silver Spring, MD 20910, USA
Mol Biochem Parasitol 172:9-18. 2010..Collectively, these data suggest a role for Pfmrk in the nucleus of the parasite presumably in regulation of the DNA replication machinery...
