Anti-inflammatory and cytotoxicity assay of Cardamom-based nutraceuticals in comparison with 1,8 -Cineol

Abstract

Aim: To investigate anti-inflammatory, cytotoxic effects and viability of Recovereez- 51% 1,8-Cineol and 1,8-Cineol (natural), and to determine safety for both of the compounds and its use in new product range of nutraceuticals.
 Methodology: Cell line was divided into two groups; one was treated with Recovereez(R) and another one with 1,8-Cineol(C). The ELISA assay method was used to measure the COX, LOX, MPO, NO, and nitrate levels. Cellular viability was performed by observing cells under the inverted phase contrast microscope, followed by MTT assay.
 Results: R&C showed a reduction in levels of inflammatory markers such as IL-6, IL-1β, TNF-α, LOX, MPO, COX, iNOS, and nitrate levels. The inhibition as observed in the levels of COX and LOX enzymes were 65%±0.1 and 59%±0.3µg/ml, and 72%±0.3 and 67%±0.4µg/ml for R&C, respectively. iNOS production showed inhibition by 70%±0.3 and 65%±0.8µg/ml and NO production were reduced by 193 and 209.5µg/ml by R&C, respectively. Again, there was a decrease in the activity of MPO by 0.35 and 0.39U/ml for R&C, respectively. The results were significant with p<0.001 compared to the Diclofenac sodium. Cell viability of 60% was observed upon treating L929 cells with R&C.
 Conclusion: R&C exerted an anti-inflammatory effect on RAW 264.7 cells without exerting cytotoxicity in a dose-dependent manner. Therefore, Recovereez could be used as an alternative treatment or to prevent inflammatory diseases. Moreover, R&C are expected to treat different types of cancer. The findings could potentially lead to the discovery of safe and effective bioactive compounds that can prevent or cure the occurrence of cancerous cells.
