Application

DL-α-Difluoromethylornithine hydrochloride hydrate has been used to reduce the effects of arginine on cell proliferation. It has also been used to investigate the effect of bisphenol A (BPA) on the migration of an established ovine trophectoderm (oTr1) cell line.

Biochem/physiol Actions

Difluoromethylornithine (Eflornithine) inhibits polyamine biosynthesis by the selective, irreversible inhibition of ornithine decarboxylase (ODC). A chemoprotective agent that blocks angiogenesis.
Inhibits polyamine biosynthesis by selective, irreversible inhibition of ornithine decarboxylase. Chemoprotective agent that blocks angiogenesis.

General description

Difluoromethylornithine is a fluorinated ornithine analog, which acts as a rate-limiting enzyme of polyamine biosynthesis. It is used to treat female facial hirsutism and human African trypanosomiasis. Difluoromethylornithine functions as a chemopreventive and chemotherapeutic agent against neuroblastoma and colorectal cancer. It exhibits cytostatic effects on mammalian cells and tissues.
