Silver nanoparticles (SNPs), owing to their wide range of biomedical applications, have recently attracted remarkable interest for use in cancer nanomedicine. The present research work investigated the anticancer activity of phytosynthesized SNPs against human cancer cell lines. Phytosynthesis of SNPs was achieved by using an aqueous extract of Salacia chinensis (SC) bark as a green source to reduce silver nitrate to silver nanoparticles. Characterization of synthesized nanoparticles demonstrated a UV–visible peak at 443 nm, ζ-potential (zetasizer) of −25.6 ± 0.34 and particle size (transmission electron microscopy analysis) in the range of 40–80 nm, which validates formation of stable silver nanoparticles. The absence of cytotoxicity against normal human fibroblasts and blood erythrocytes confirms the biocompatible nature of green synthesized SNPs. In vitro anticancer assay demonstrated IC50 values of 6.31, 4.002, 5.228, 8.452, 14.37, 7.46, and 6.55 μg/mL against liver (Hep G2), lungs (L-132), pancreas (MIA-Pa-Ca-2), breast (MDA-MB-231), oral (KB cells), prostate (PC-3), and cervical (HeLa) cancer cell lines respectively, which confirms its potent anticancer action. The results of the present study give an experimental proof that the SC mediated green synthesized SNPs could serve as a promising anticancer agent to overcome limitations of existing conventional cancer chemotherapeutics.

银纳米粒子的植物合成:表征,生物相容性研究和抗癌活性。

银纳米颗粒(SNPs)由于其广泛的生物医学应用,最近引起了人们对于在癌症纳米医学中使用的极大兴趣。本研究工作研究了植物合成的SNP对人类癌细胞系的抗癌活性。植物的SNP合成是通过使用中华ala(Salacia chinensis)的水提物来完成的。(SC)树皮作为绿色来源,可将硝酸银还原为纳米银颗粒。合成的纳米颗粒的表征显示在443 nm处有一个可见紫外峰,ζ势(zetasizer)为-25.6±0.34,粒径(透射电子显微镜分析)在40–80 nm范围内,这证明了稳定的银纳米颗粒的形成。 。没有针对正常人成纤维细胞和血液红细胞的细胞毒性,证实了绿色合成SNP的生物相容性。体外抗癌试验证明IC 50对肝脏(Hep G2),肺(L-132),胰腺(MIA-Pa-Ca-2),乳房(MDA-MB- 231),口服(KB细胞),前列腺癌(PC-3)和宫颈癌(HeLa)癌细胞系,这证实了其有效的抗癌作用。本研究的结果提供了实验证明,SC介导的绿色合成SNPs可以作为有望克服现有常规癌症化学治疗方法局限性的抗癌药。
