Daclatasvir dihydrochloride has important roles not only in the management of COVID-19 pandemic symptoms but also in the treatment of chronic hepatitis C infection.
The current research presents four novel and simple platforms including silver-nanoparticles spectrophotometric technique and three electrochemical conductometric ones for daclatasvir analysis in its tablet, biological fluids, and dissolution media.
The spectrophotometric platform involved the synthesis of silvernanoparticles through a redox reaction between the reducing agent (daclatasvir) and the oxidizing agent (silver nitrate) in presence of polyvinylpyrrolidone as a stabilizing agent. The produced silver-nanoparticles have an intense surface plasmon resonance peak at 421 nm where the measured absorbance values were utilized for quantitative spectrophotometric determination of daclatasvir. While the electrochemical conductometric platforms involved the reaction of daclatasvir with three different precipitating reagents (silver nitrate, phosphomolybdic acid, and ammonium reineckate) to form ion associates between these reagents and daclatasvir in the aqueous system.
All proposed platforms were validated in line with recommendations of the international conference on harmonization producing satisfactory outcomes within the agreed boundaries.
The proposed platforms are green alternatives for routine rapid assay of daclatasvir at the cheapest cost because their results were observed to be nearly similar to those of the reported platform. Moreover, the suggested spectrophotometric platform's sensitivity can be employed for investigating daclatasvir bioequivalence.
盐酸达拉他韦不仅在新冠疫情症状管理中发挥重要作用,还在慢性丙型肝炎感染治疗中具有重要作用。
当前研究提出了四种新颖且简单的平台,包括银纳米颗粒分光光度法技术和三种电化学电导法技术,用于分析片剂、生物流体及溶出介质中的达拉他韦。
分光光度平台涉及在聚乙烯吡咯烷酮作为稳定剂存在的情况下,通过还原剂(达拉他韦)与氧化剂(硝酸银)之间的氧化还原反应合成银纳米颗粒。所产生的银纳米颗粒在421nm处有一个强烈的表面等离子体共振峰,利用测得的吸光度值对达拉他韦进行定量分光光度测定。而电化学电导平台则涉及达拉他韦与三种不同的沉淀剂(硝酸银、磷钼酸和雷氏铵盐)反应,在水体系中形成这些试剂与达拉他韦之间的离子缔合物。
所有提出的平台均按照国际协调会议的建议进行了验证,在商定的范围内产生了令人满意的结果。
所提出的平台是以最低成本对达拉他韦进行常规快速检测的绿色替代方法,因为观察到它们的结果与报道的平台几乎相似。此外,所建议的分光光度平台的灵敏度可用于研究达拉他韦的生物等效性。
