$N^1$-Benzyl-4-methylbenzene-1,2-diamine (JSH-21) and its analogs were chemically synthesized and their anti-inflammatory potentials investigated. JSH-21 inhibited nitric oxide (NO) production in lipopolysaccharide (LPS)-stimulated macrophages RAW 264.7 in a dose-dependent manner, with an $IC_{50}$ value of 9.2 ${\mu}M$, where pyrrolidine dithiocarbamate and parthenolide as positive controls exhibited $IC_{50}$ values of 29.3 and 3.6 ${\mu}M$, respectively. The inhibitory effect of JSH-21 on the NO production was attributable to its down-regulatory action on LPS-inducible NO synthase (iNOS), which was documented by iNOS promoter activity. In the mechanism of the anti-inflammatory action, JSH-21 exhibited inhibitory effects on LPS-induced DNA binding activity and transcriptional activity of nuclear factor-kappa B (NF-$_KB$). Structural analogs of JSH-21 also inhibited both the LPS-induced NO production and NF-$_KB$). transcriptional activity, where diamine substitution at positions 1 and 2 of JSH-21 seems to play an important role in the anti-inflammatory activity.
