Eflornithine(DFMO) inhibits polyamine biosynthesis by irreversible inhibition of ornithine decarboxylase(ODC). It is a chemotherapeutic protectant that blocks angiogenesis. Its biological half-life is 8 hours[1-2].

Eflornithine (0.5 mM DFMO;72h) sensitizes homologous recombination (HR)-Competent Ovarian Cancer Cells to Rucaparib [3]. Combination of Eflornithine (1 mM; 48 h) and Thymoquinone (TQ) significantly reduced cell viability and resulted in significant synergistic effects on apoptosis when compared to either Eflornithine or TQ alone in Jurkat cells [4]. Eflornithine (5 mM;72h) treatment leads to the accumulation of the cyclin-dependent kinase inhibitor p27(Kip1) protein and causes p27(Kip1)/Rb-coupled G (1) cell cycle arrest in MYCN-amplified NB tumor cells through a process that involves p27(Kip1) phosphorylation at residues Ser10 and Thr198[5].

Eflornithine (1% w/v in the drinking water; 48-72 h) alone markedly increases survival of pancreatic tumor-bearing mice in contrast with GW5074 across multiple dosing and tumor seeding strategies [6]. The Kras(G12D/+) mice fed Eflornithine at 0.1% and 0.2% in the diet showed a significant inhibition of pancreatic ductal adenocarcinoma (PDAC) incidence compared with mice fed control diet [7].
