Biochem Physiol Actions: Furamidine (DB75) binds to strings of AT base pair sequences in DNA's minor groove. Furamidine was originally developed as an anti-parasitic compound for a variety of diseases including Chagas' disease. Furamidine targets AT rich sequences in trypanosome kinetoplast minicircle DNA (kDNA), resulting in subsequent destruction of the kinetoplast and cell death. Furamidine has also been found to inihbit tyrosyl-DNA phosphodiesterase (Tdp1) and act as a selective protein arginine methyltransferase 1 (PRMT1) inhibitor with an IC50 of 9.4µM.
