4-Methyl-N'-(3-phenyl-propyl)-benzene-1,2-diamine (JSH-23) is a novel chemically synthetic compound. The aromatic diamine JSH-23 compound exhibited inhibitory effect with an IC50 value of 7.1 muM on nuclear factor (NF)-kappaB transcriptional activity in lipopolysaccharide (LPS)-stimulated macrophages; RAW 264.7, and interfered LPS-induced nuclear translocation of NF-kappaB without affecting IkappaB degradation. This mechanism of action is very rare for controlling NF-kappaB activation. Furthermore, the compound inhibited not only LPS-induced expressions of tumor necrosis factor-alpha, interleukin (IL)-1beta, IL-6 and inducible nitric oxide synthase and cyclooxygenase-2 but also LPS-induced apoptosis of the RAW 264.7 cells.
