PRMT1-IN-1, a PRMT1 inhibitor, selectively targets the protein arginine methyltransferase 1 enzyme, which plays a pivotal role in various cellular processes, such as gene regulation and signal transduction [1].

Bisubstrate inhibitor 78 is an inhibitor of nicotinamide N-methyltransferase (NNMT; IC50= 1.41 μM).1It binds the NNMT active site in the binding pockets for the NNMT substrates S-adenosyl-L-methionine (SAM) and nicotinamide . Bisubstrate inhibitor 78 is selective for NNMT over histone-lysine N-methytransferase NSD2 and protein arginine methyltransferase 1 (PRMT1; IC50s = >50 μM for both). It reduces levels of 1-methylnicotinamide in, and inhibits proliferation of, HSC-2 oral cancer cells when used at a concentration of 100 μM.This compound is unstable in powder form and other related salt forms are recommended.

CARM1-IN-1 (CARM1-IN-7G) is a selective inhibitor of CARM1 with IC50 of 8.6 μM. CARM1-IN-1 shows weak activity against PRMT1 and SET7 with IC50 > 600 μM.

DCLX069 is a selective protein arginine methyltransferase 1 (PRMT1) inhibitor with an IC50 value of 17.9 µM, occupying the SAM binding pocket to exert its inhibitory effect. It effectively blocks cell proliferation in breast cancer, liver cancer, and acute myeloid leukemia cell lines.

Furamidine is a cell-permeable, selective inhibitor of protein arginine methyltransferase 1 (PRMT1). Furamidine binds to strings of AT base pair sequences in DNA′s minor groove. Furamidine targets the enzyme active site and is primarily competitive with t

CARM1-IN-1 hydrochloride is a potent and selective inhibitor of CARM1 (IC50: 8.6 μM) with minimal inhibition of PRMT1 and SET7.

PRMT4-IN-2 (compound 55) acts as a pan-inhibitor across various protein arginine methyltransferase (PRMT) isoforms, exhibiting inhibitory potencies with IC50 values of 92 nM for PRMT4, 436 nM for PRMT6, 460 nM for PRMT1, 823 nM for PRMT8, and 1.386 μM for PRMT3 [1].

CARM1-IN-4 (compound 11f) serves as a potent inhibitor of CARM1, exhibiting IC50 values of 9 nM for CARM1 and 56 nM for PRMT1. This compound significantly inhibits the proliferation of colorectal cancer cell lines and curtails the methyltransferase activity of CARM1, blocking the methylation of downstream proteins. Moreover, CARM1-IN-4 induces apoptosis and demonstrates notable antitumor activity [1].
