Furamidine dihydrochloride (DB75 dihydrochloride) is a cell-permeable, selective small molecule inhibitor of protein arginine methyltransferase 1 (PRMT1) that also binds preferentially to strings of AT base pair sequences within the minor groove of DNA; it targets the PRMT1 enzyme active site primarily through a competitive mechanism with the protein substrate and is noncompetitive toward the cofactor, ultimately leading to the blockade of cell proliferation in various leukemia cell lines irrespective of their genetic lesions.

| Targets&IC50 | PRMT4:>400 µM (IC50), PRMT5:166 µM (IC50), PRMT6:283 µM (IC50), Protein arginine methyltransferase 1 (PRMT1):9.4 μM (IC50) |
| In vitro | Furamidine dihydrochloride (20 μM, 72 hours) treatment of leukemia cell lines inhibited cell growth in most leukemia cell lines except HEL cells harboring the JAK2V617F mutation.[6] |
| In vivo | Furamidine dihydrochloride (1 mg/kg, intraperitoneal injection, 3 times a week, repeated every 4 weeks for 34 weeks) was used to treat female NZB/NZW mice and was found to suppress proteinuria and prolong the survival of lupus-prone NZB/NZW mice when combined with irinotecan. [5] |
