S-Nitroso-N-acetylcysteine inhibits proliferation and survival of multiple MM cells. It acts by the S-nitrosylation-dependent inhibition of STAT3 and NF-κB.
Folcysteine is a cysteine derivative with potential antitumor agent. It's a vitamin that used to synthesize DNA, conduct DNA repair and methylate DNA. It also acts as a cofactor in biological reactions involving folate.
Lysylcysteine is a dipeptide composed of lysine and cysteine. It is an incomplete breakdown product of protein digestion or protein catabolism. Some dipeptides are known to have physiological or cell-signaling effects although most are simply short-lived
Farnesylcysteine (FC) serves as a competitive inhibitor of ICMT and is associated with an ABA hypersensitive phenotype in Arabidopsis thaliana. The fcly mutant exhibits reduced farnesylcysteine (FC) lyase activity and shows an increased response to ABA [1].
