    Abstract:
    BACKGROUND: Colorectal cancer is among the most common cancers and accounts for nearly 9% of all cancers in the world. Chrysophanol is a naturally occurring anthraquinone exerts a number of pharmacological activities such as anti-inflammation, anti-cancer, anti-bacterial, anti-viral, and anti-oxidant effects. This study aims to produce a novel gemini chrysophanol nanoparticles (Gemini-Chr NPs), and to evaluate its anti-cancer effect on the human colorectal cancer cell lines. METHODS: Gemini-Chr NPs were synthesized through nanoprecipitation method and characterized by dynamic light scattering and scanning electron microscopy, Anti-cancer activities were examined through MTT assay on HCT-116 cancer cells, apoptosis was investigated via Annexin V-FITC/PI dual stain assay. Furthermore, the expression of Bax, Bcl-2 and P53 genes were evaluated using real-time PCR and western blotting assay.  RESULTS: The average particle diameter of the synthesized Gemini-Chr NPs and zeta potential were recorded as 120 nm and 14.4 mV, respectively. In comparison to the normal cells, the cytotoxicity assay confirmed that Gemini-Chr NPs preferentially killed colorectal cancer cells via induction of apoptosis. Moreover, Gemini-Chr NPs could upregulate the expression of Bax in both cancerous and normal cells (p ≤ 0.05) and decreasing the Bcl-2 expression in only tumor cells (p ≤ 0.01), while the expression of P53 is modulated in tumor cells (p ≤ 0.05). CONCLUSIONS: Gemini surfactants could be considered for efficient delivery and improvement of anti-cancer effect of chrysophanol. Gemini-Chr NPs might have the potential for developing novel therapeutic agent against colorectal cancer.
