Abstrakt: Introduction Dopamine is an important neuroregulatory hormone and is secreted during exercise. Its role in physiological regulation is not fully uncovered. Recent studies showed that it suppresses inflammation. Colon cancer is one of the most predominant cancers in the population and is influenced by prolonged inflammation. The anti-inflammatory effect of dopamine using the colon cancer model was analyzed in KB cells. Methods KB cells were cultured using Dulbecco's Modified Eagle Medium   and Inhibitory Concentration- 50 (IC 50 ) was determined by 3-[4,5-dimethylthiazol-2-yl]-2,5 diphenyl tetrazolium bromide assay. BCl-2, tumour necrosis factor-α (TNF-α), nuclear factor kappa- B (​​​​​NF-kB), and interleukin (IL)-6 were assessed using reverse transcription polymerase chain reaction (RT-PCR)(at 50 and 100 µg/ ml < IC 50 ). Schrödinger was used for docking analysis using nuclear factor Kappa B (NF-kB) (Protein Data Bank: 5T8O) and dopamine (CID 681). Results Results were represented as mean ± standard deviation and statistically evaluated. Dopamine showed severe growth inhibition in KB cells (IC 50 - 225±3.1µg/ ml). It downregulated the expression of BCl-2, NF-k, and IL-6, but increased TNF-α expression. Dopamine bonded with NF-kB by two hydrogen bonds with aspartic acid​​-53and alanine-54, respectively). Conclusion The present study revealed that dopamine has a significant anti-cancer potential by blocking NF - kB   pathways in KB cells.
