Colon cancer is one of the major prevailing types of cancer worldwide. It has been the most important public health difficulty. Thus, we planned phytoconstituents arbitrated synthesis of gold nanoparticles (AuNPs) and examined their curative efficacy against the colon cancer (HCT-116) cells. In this current study, we formulated the AuNPs by using (AL) aqueous leaf extract by the green method and synthesized AL-AuNPs were distinguished by UV-visible spectroscopy (UV-vis), energy dispersive X-ray diffraction (XRD), selected area (electron) diffraction (SAED) pattern, Fourier transform infrared spectroscopy (FTIR) and high-resolution transmission electron microscopy (HR-TEM). Synthesized AL-AuNPs confirmed by the UV absorption highest at 535 nm and the crystal structure of AL-AuNPs was additionally established by XRD and SAED pattern. HR-TEM images explained the size and morphology allocation of nanoparticles. FTIR analysis confirmed the presence of alkynes, aromatic compounds, and alkenes of biomolecules in AL-AuNPs. Furthermore, AL-AuNPs induced cytotoxicity at the IC concentration 48 µg/ml and also induced apoptosis by enhanced ROS production, decreased ΔΨm, apoptotic morphological changes by AO/EtBr and altering pro and anti-apoptotic protein expressions were analyzed in HCT-116 colon cancer cells. The findings of this investigation proved that the AL-AuNPs were revealed the potential anticancer activity against colon cancer (HCT-116) cells.
结肠癌是全球主要的流行癌症类型之一。它一直是最重要的公共卫生难题。因此,我们计划通过植物成分介导合成金纳米颗粒(AuNPs),并研究它们对结肠癌(HCT-116)细胞的治疗效果。在本研究中,我们采用绿色方法利用(AL)叶水提取物制备了AuNPs,并通过紫外可见光谱(UV-vis)、能量色散X射线衍射(XRD)、选区(电子)衍射(SAED)图谱、傅里叶变换红外光谱(FTIR)和高分辨率透射电子显微镜(HR-TEM)对合成的AL-AuNPs进行了表征。合成的AL-AuNPs在535nm处的紫外吸收最高,通过XRD和SAED图谱进一步确定了AL-AuNPs的晶体结构。HR-TEM图像解释了纳米颗粒的尺寸和形态分布。FTIR分析证实了AL-AuNPs中存在生物分子的炔烃、芳香化合物和烯烃。此外,在HCT-116结肠癌细胞中分析了AL-AuNPs在48μg/ml的IC浓度下诱导细胞毒性,还通过增强ROS产生、降低ΔΨm、AO/EtBr诱导的凋亡形态变化以及改变促凋亡和抗凋亡蛋白表达诱导凋亡。本研究结果证明,AL-AuNPs对结肠癌(HCT-116)细胞具有潜在的抗癌活性。
