Abstract

Malaria is a mosquito-borne infectious disease that is caused by the parasite. Most of the available medication are losing their efficacy. Therefore, it is crucial to create fresh leads to combat malaria. Green silver nanoparticles (AgNPs) have recently attracted a lot of attention in biomedical research. As a result, green mediated AgNPs from leaves of , a medicinal plant with purported antimalarial effects, were used in this investigation. Initially, cysteine-rich proteins from species were studied as potential therapeutic targets. With docking scores between -9.93 and -11.25 kcal/mol, four leaf constituents of were identified. The green mediated silver nanoparticles were afterward produced using leaf extract and were further examined using UV-vis spectrophotometer, DLS, Zeta potential, FTIR, XRD, and FESEM. The size of synthesized TBL-AgNPs was validated by the FESEM results; the average size of TBL-AgNPs was around 44.05 nm. The zeta potential study also supported green mediated AgNPs stability. Additionally, (3D7) cultures were used to assess the antimalarial efficacy, and green mediated AgNPs could effectively inhibit the parasitized red blood cells (pRBCs). In conclusion, this novel class of AgNPs may be used as a potential therapeutic replacement for the treatment of malaria.

摘要

疟疾是一种由寄生虫引起的蚊媒传染病。大多数现有的药物正在失去其疗效。因此,开发新的抗疟线索至关重要。绿色银纳米颗粒(AgNPs)最近在生物医学研究中引起了广泛关注。因此,本研究使用了具有抗疟作用的药用植物的叶子通过绿色介导合成的AgNPs。最初,研究了该物种中富含半胱氨酸的蛋白质作为潜在的治疗靶点。通过对接分数在-9.93至-11.25千卡/摩尔之间,鉴定出该植物的四种叶成分。随后使用叶提取物制备绿色介导的银纳米颗粒,并使用紫外可见分光光度计、动态光散射仪、zeta电位仪、傅里叶变换红外光谱仪、X射线衍射仪和场发射扫描电子显微镜进行进一步检测。场发射扫描电子显微镜结果验证了合成的TBL-AgNPs的尺寸;TBL-AgNPs的平均尺寸约为44.05纳米。zeta电位研究也支持绿色介导的AgNPs的稳定性。此外,使用恶性疟原虫(3D7)培养物评估抗疟效果,绿色介导的AgNPs可以有效抑制被寄生的红细胞(pRBCs)。总之,这类新型的AgNPs可作为治疗疟疾的潜在治疗替代品。
