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

In Vitro

Furamidine (compound 1; 20 μM; 72 hours; leukemia cell lines) inhibits cell growth for most of the leukemia cell lines except HEL cells which have JAK2V617F mutations^[1].
Furamidine (compound 1; 20 μM; 15 hours; 293T cells) treatment significantly reduces the expression level of the methylated GFP-ALY protein in 293T cells^[1].
Furamidine binds duplex DNA in the DNA minor groove selectively at AT rich sites [(A/T)4]. Furamidine can also intercalate between GC base pairs of duplex DNA. Furamidine could therefore interfere with DNA processing enzymes such as TDP-1^[2].

The combination treatment does not change the levels of anti-dsDNA antibodies^[3].

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
