General description

Furamidine dihydrochloride is an analog of the aromatic drug pentamidine and a substrate of the organic cation transporter 1 (OCT1). A number of prodrugs of furamidine dihydrochloride are being synthesised and are in clinical trial stages.

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.

Protein arginine methylation is a posttranslational modification critical for a variety of biological processes. Misregulation of protein arginine methyltransferases (PRMTs) has been linked to many pathological conditions. Most current PRMT inhibitors display limited specificity and selectivity, indiscriminately targeting many methyltransferase

The antiparasitic activity of aromatic diamidine drugs, pentamidine and furamidine, depends on their entry into the pathogenic protozoa via membrane transporters. However, no such diamidine transporter has been identified in mammalian cells. The goal of this study is to investigate

By enzymatically hydrolyzing the terminal phosphodiester bond at the 3'-ends of DNA breaks, tyrosyl-DNA phosphodiesterase (Tdp1) repairs topoisomerase-DNA covalent complexes and processes the DNA ends for DNA repair. To identify novel Tdp1 inhibitors, we developed a high-throughput assay that uses
