Due to side-effects and inefficiency of the drugs used in malaria treatment, finding alternative medicine with less side-effects has attracted much attention. In this regard, in the present study, nanocomposite synthesized and its effects on the metabolites of P. falciparum were investigated. Subsequent to synthesis of nanocomposites, characterization was carried out using nuclear magnetic resonance (NMR), liquid chromatography-mass spectrometry (LC-MS), scanning electron microscopy, dynamic light scattering and Fourier-transform infrared tests. Solubility and drug release were measured and its toxicity on Vero cell was assessed using the MTT assay. The antiparasitic effect of the nanocomposite on the metabolites of P. falciparum was investigated by 1H NMR spectroscopy. Among synthesized nanocomposites, the average size of 239 nm showed suitable solubility in water as well as slow drug release. The MTT assay showed no toxicity for Vero cell lines. Concentrations of 2.5 μg mL-1 of nanocomposite eliminated 82.6% of the total parasites. The most effected metabolic cycles were glyoxylate and dicarboxylate metabolism. In this study, 1H NMR spectroscopy was used with untargeted metabolomics to study the effect of the nanocomposite on P. falciparum. Playing an essential role in understanding drug-target interactions and characterization of mechanism of action or resistance exhibited by novel antiprotozoal drugs, can be achieved by targeting metabolic using LC-MS.
由于疟疾治疗药物的副作用和效率低下,寻找副作用较小的替代药物引起了广泛关注。在这方面,本研究合成了纳米复合材料,并研究了其对疟原虫代谢物的影响。在合成纳米复合材料之后,使用核磁共振(NMR)、液相色谱-质谱(LC-MS)、扫描电子显微镜、动态光散射和傅里叶变换红外测试对其进行了表征。测量了其在水中的溶解度和药物释放,并通过 MTT 测定法评估了其对 Vero 细胞的毒性。通过 1H NMR 光谱研究了纳米复合材料对疟原虫代谢物的抗寄生虫作用。在所合成的纳米复合材料中,平均尺寸为 239nm 的纳米复合材料在水中具有合适的溶解度和缓慢的药物释放。MTT 测定法表明 Vero 细胞系没有毒性。浓度为 2.5μg mL-1的纳米复合材料消除了 82.6%的总寄生虫。受影响最大的代谢循环是乙醛酸和二羧酸代谢。在这项研究中,使用非靶向代谢组学的 1H NMR 光谱研究了纳米复合材料对疟原虫的影响。通过靶向 LC-MS 代谢,可以了解药物-靶标相互作用,并对新型抗原生动物药物的作用机制或耐药性进行特征描述,从而发挥重要作用。
