DescriptionHalofuginone is a low molecular weight quinazolinone alkaloid, and a potent inhibitor of collagen alpha1(I) and matrix metalloproteinase 2 (MMP-2) gene expression. Halofuginone also effectively suppresses tumor progression and metastasis in mice. Collgard Biopharmaceuticals is developing halofuginone for the treatment of scleroderma and received orphan drug designation from the U.S. Food and Drug Administration in March, 2000.
  • Halofuginone hydrobromide
  • Halofuginone lactate
Brand Names
  • Halocur
  • Stenorol
  • Tempostatin
Affected Organism
  • Humans and other mammals
  • Protozoa
IndicationFor the treatment of scleroderma, cancer, and restenosis.
PharmacologyHalofuginone, a fully synthetic small molecule, is a potent and selective regulator of stromal cell activation, cell migration and Collagen type I synthesis, a process that has been identified as a 'master switch' in the body's tissue repair process.
Mechanism of actionHalofuginone is a potent inhibitor of collagen a1(I) and matrix metalloproteinase 2 (MMP-2) gene expression. Halofuginone also suppresses extracellular matrix deposition and cell proliferation. The profound antitumoral effect of halofuginone is attributed to its combined inhibition of the tumor stromal support, vascularization, invasiveness, and cell proliferation.
