Resumo: | Abstract Chronic inflammation is a common indication of several diseases, e.g. asthma, chronic obstructive pulmonary disease (COPD), atherosclerosis, etc. Benzimidazole derivatives are preferable compounds to design new analgesic and anti-inflammatory substances due to their unique biological features. We aimed to investigate the effect of a newly synthesized benzimidazole derivative, ORT-83, on A549 human lung adenocarcinoma cell line. ORT-83 was synthesized, and a non-cytotoxic concentration of ORT-83 on A549 cells was detected with MTT assay. To analyze the anti-inflammatory effect of ORT-83, an inflammatory cell culture model was established by stimulating A549 cell line with IL1-β (10 ng/ml). After 2 hours of treatment with IL1-β to induce inflammation, A549 cells were exposed to ORT-83 (0.78 µg/ml) for 24 hours. Thereafter gene expression analyses were performed with qRT-PCR. We found that ORT-83 significantly suppressed the gene expression levels of the proinflammatory cytokines; IL-6, NFkB, and TNF-α. However, the increased levels of IL-10 (2.8 folds) by IL-1β induction did not change after ORT-83 and/or dexamethasone (Dex: positive control) treatments. While Dex; a COX-2 inhibitor, reduced the COX-2 expression level in inflammatory cells from 10.03 folds to 0.71 folds, ORT-83 reduced its level to 4.37 folds. iNOS expression levels did not change in any experimental groups. In conclusion, we showed that ORT-83 exerted its anti-inflammatory effects by repressing the gene expression of proinflammatory cytokines in the inflammation-induced A549 cell line. Although ORT-83 had a weaker COX-2 inhibitory effect compared to Dex, it was shown to be still a strong anti-inflammatory compound. |
