GtoPdb Ligand ID: 10153

PDB Ligand Antimalarial Ligand
Compound class: Synthetic organic
Comment: Halofuginone is a synthetic derivative of febrifugine, a quinazolinone alkaloid first isolated from the roots of the blue evergreen hydrangea (D. febrifuga) and used as an antimalarial remedy in traditional Chinese medicine. The INN record for halofuginone indicates that it is a racemic mixture. We show the chemical structure without stereochemistry to represent the mixture.
