Anti-proliferative and immunomodulatory potencies of cinnamon oil on Ehrlich ascites carcinoma bearing mice

• Cinnamon is a well-known natural spice and flavoring substance used worldwide. The objective of the present work is to explore the possible antitumor and immunomodulatory potencies of cinnamon essential oil (Cinn) on Ehrlich ascites carcinoma (EAC). A total of fifty female Swiss albino mice were sub-grouped into five groups (n = 10), namely, normal (a non-tumorized and non-treated) group; EAC-tumorized and non-treated group; Cinn (non-tumorized mice received Cinn, 50 mg/kg per body weight daily) group; a group of EAC-tumorized mice treated with Cinn and the final positive control group of EAC-tumorized mice received cisplatin. Eight compounds were identified from Cinn using UPLC-MS-Qtof and NMR analysis. Compared to EAC untreated group, Cinn successfully (P < 0.05) inhibited tumor growth by reducing tumor cell count (45%), viability (53%) and, proliferation accompanied by the inhibition of tumor growth rate. Moreover, a significant (P < 0.05) arrest in the cell cycle at G0/G1 phase was noticed following Cinn treatments (~ 24.5%) compared to EAC group. Moreover, Cinn markedly evoked an antitumor immune response by elevating the percentage of splenic T helper (CD3+CD4+) and T cytotoxic (CD3+CD8+) cells. It is noteworthy that Cinn treatments significantly restored different hematological alterations as well as liver and kidney functions in EAC-tumorized mice. In conclusion, results suggest that Cinn has a good antitumor and immunostimulatory potencies against Ehrlich ascites carcinoma in vivo. The mechanism underlying its antitumor activity may be attributed to its immunostimulatory effects which increase its potential as a promising anticancer candidate.
