This is beta-release v2.0 of the GtoMPdb. It contains the majority of features and functionality expected in the full public release. However, it remains under development and while it should not contain any critical bugs, some portions are not yet optimised and may lack full functionality or content. Report a bug

halofuginone PfDd2

Plasmodium falciparum Dd2

P. falciparum strain Dd2 (PfDd2) is a clone derived from PfW2, following continuous culture in mefloquine. PfW2 was cloned from the Indochina III/CDC isolate, originally derived from a Laotian patient who failed chloroquine therapy.
PfDd2 can be obtained from the Malaria Research and Reference Reagent Resource Center (MR4) and is reported to be resistant to chloroquine, pyrimethamine and mefloquine.

halofuginone Pf3D7

Plasmodium falciparum 3D7

P. falciparum strain 3D7 (Pf3D7) was derived from isolate NF54 by limiting dilution. The complete genome of Pf3D7 has been sequenced (GenBank: LN999946.1).
Pf3D7 can be obtained from the European Malaria Reagent Repository or the Malaria Research and Reference Reagent Resource Center (MR4) and is sensitive to a panel of antimalarial compounds including chloroquine and pyrimethamine.

Malaria Pharmacology Comments
The aminoacyl-tRNA synthetases are emerging targets for antimalarial agents [4]. Although sharing a common tRNA esterification catalytic activity, these proteins are structurally diverse and physiologically distinct enzymes.
