Furamidine (dihydrochloride)

Furamidine dihydrochloride (DB75 dihydrochloride) is a selective protein arginine methyltransferase 1 (PRMT1) inhibitor with an IC50 of 9.4 μM. Furamidine dihydrochloride is selective for PRMT1 over PRMT5, PRMT6, and PRMT4 (CARM1) (IC50s of 166 μM, 283 μM, and >400 μM, respectively) . Furamidine dihydrochloride is a potent, reversible and competitive tyrosyl-DNA phosphodiesterase 1 (TDP-1) inhibitor. Inhibition of TDP-1 by Furamidine dihydrochloride is effective both with single- and double-stranded DNA substrates but is slightly stronger with the duplex DNA. Furamidine dihydrochloride is also an antiparasite agent[1][2][3].
