Background : Anemarrhena asphodeloides has efficacy such as anti-fungal, anti-cancerous, anti-inflammatory, anti-diabetic, Anti-UV etc. Metal nanoparticles are used for photo imaging, cancer resection and drug delivery etc in medical field. Therefore A. asphodeloides nanoparticles will be expected better efficacy for therapeutic properties in medical field.
Methods and Results : The water extract of A. asphodeloides mediated the synthesis of Aa-AgNPs and Aa-AuNPs. Their characterized by several physicochemical techniques such as UV-Vis spectrophotometry, FE-TEM, EDX spectroscopy, SAED pattern, DLS size analysis, XRD analysis, and FTIR analysis. Both Aa-Ag/AuNPs were evaluated for cytotoxicity towards 3T3-L1, A549, HT29 and MCF7. Aa-AgNPs and Aa-Au NPs were found to be spherical, face-centered cubic nanocrystals with hydrodynamic diameter of 190 and 258 ㎚. In vitro cytotoxic analysis revealed that up to 50 ㎍/㎖-1 concentration Aa-Au NPs did not exhibit any toxicity on 3T3-L1, HT29 and MCF7 cell lines, while being specifically cytotoxic to A549 cell line. On the contrary, Aa-Ag NPs displayed a significantly higher toxicity in all cell lines specially MCF7 cell line. ROS generation was not affected by Aa-Au NPs, but Aa-AgNPs has a higher potential to induce oxidative stress in A549 cells than HT29 and MCF7 cells. Aa-Au NPs have the potential for anticancer agent during lung cancer treatment. Aa-AgNPs is also exhibited to inhibit cell migration by induce oxidatie stress.
Conclusion : The Aa-Au/AgNPs might have the anticancer potential and might be effective in the lung cancer therapy, however further evaluation is must needed.
