In recent years, silver nanoparticles have been used as modern chemotherapeutic drugs to treat several cancers such as pancreatic, breast, prostate, and blood cancers. No previous reports demonstrated the in vitro anti-human pancreatic cancer effects of the novel chemotherapeutic drug formulated by silver nanoparticles containing Berberis thunbergii leaf (AgNPs). The synthesized AgNPs were characterized using different techniques including UV-vis. and FT-IR spectroscopy, X-ray diffraction, scanning electron microscopy (SEM), and TEM. All techniques approved the synthesized silver nanoparticles. The SEM and TEM exhibited a uniform spherical morphology and an average size of about 15 nm for the biosynthesized nanoparticles, respectively. The 4-(dimethylamino)benzaldehyde,2,2-diphenyl-1- pikrilhydrazil (DPPH) test revealed similar antioxidant potentials for B. thunbergii leaf aqueous extract, AgNPs, and butylated hydroxytoluene. AgNPs inhibited half of the DPPH molecules in the concentration of 108 μg/mL. To survey the anti-human pancreatic cancer activities of AgNO , B. thunbergii leaf aqueous extract, and AgNPs, 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl-2H-tetrazolium bromide (MTT) assay was used on common human pancreatic cancer cell lines. AgNPs had very low cell viability and anti-human pancreatic cancer effects dose-dependently against PANC-1, AsPC-1, and MIA PaCa-2. The IC50 values of the AgNPs were 259, 268, and 141 μg/mL against PANC-1, AsPC-1, and MIA PaCa-2 cell lines, respectively. It is thought that the AgNPs obtained can be used as an anticancer drug for the diagnosis of pancreatic cancer in humans after acceptance of the above findings in clinical study trials.
近年来,纳米银已被用作治疗多种癌症的现代化疗药物,如胰腺癌、乳腺癌、前列腺癌和血癌。以前没有报道表明,含有小檗叶的新型化疗药物纳米银(AgNPs)对体外人胰腺癌细胞有抑制作用。采用不同技术,包括紫外-可见光谱和傅里叶变换红外光谱、X 射线衍射、扫描电子显微镜(SEM)和透射电子显微镜(TEM)对合成的 AgNPs 进行了表征。所有技术均证实了合成的银纳米颗粒。SEM 和 TEM 分别显示了生物合成纳米颗粒的均匀球形形态和约 15nm 的平均粒径。4-(二甲基氨基)苯甲醛、2,2-二苯基-1-吡啶肼(DPPH)试验表明,小檗叶水提物、AgNPs 和丁基化羟基甲苯具有相似的抗氧化潜力。AgNPs 在 108μg/mL 的浓度下抑制了一半的 DPPH 分子。为了研究 AgNO3、小檗叶水提物和 AgNPs 对人胰腺癌细胞的抗活性,采用 3-(4,5-二甲基噻唑-2-基)-2,5-二苯基-2H-四唑溴盐(MTT)法对常见的人胰腺癌细胞系进行了检测。AgNPs 对 PANC-1、AsPC-1 和 MIA PaCa-2 具有非常低的细胞活力和抗人胰腺癌细胞作用,并呈剂量依赖性。AgNPs 对 PANC-1、AsPC-1 和 MIA PaCa-2 细胞系的 IC50 值分别为 259、268 和 141μg/mL。认为获得的 AgNPs 可以在临床研究试验中接受上述发现后,作为人类胰腺癌的抗癌药物。
