Abstract Tamoxifen (TAM) and Sulphoraphane (SFN) are well-known anti-estrogen drugs used for the treatment of breast cancer. Due to their synergistic therapeutic potential, their combination is preferred as it helps to minimize the drug-related toxicities and enhances therapeutic efficacy. A simple, robust and fast simultaneous reversed-phase high-performance liquid chromatography (RP-HPLC) method was developed as well validated for the analysis of both the drugs based on their particular wavelength. The separation was performed on C18 analytical column with dimensions of 4.6 × 250 mm, 5 μm using mobile phase methanol: water (pH 3.5) in the ratio 70:30 and flow rate of 0.8 min/mL. Box-Behnken experimental design was used to optimized these independent variables and analyze their effect on the response variables like retention time (RT), no. of theoretical plates and tailing factor of both analytes. Method validation was carried out for establishing the specificity, linearity range, accuracy, sensitivity, robustness, precision and ruggedness. The method applicability was evaluated on different nanoformulations, i.e., solid lipid nanoparticles (SLNs), liposomes (LIPO), nanostructured lipid carriers (NLCs). The peaks of the analyte were found to be well resolved and two distinct RT were recorded for TAM and SFN. Calibration curves were found to be linear for TAM and SFN over concentration range of 6–24 μg/mL. All method validation criteria were within the range of acceptance. Relative standard deviation (%RSD) was observed to be

RP-HPLC 方法的系统开发和验证,用于同时估计他莫昔芬和萝卜硫素,具体应用于纳米脂质制剂

摘要 他莫昔芬(TAM)和萝卜硫素(SFN)是众所周知的抗雌激素药物,用于治疗乳腺癌。由于它们的协同治疗潜力,它们的组合是首选,因为它有助于最大限度地减少药物相关的毒性并提高治疗效果。开发了一种简单、稳健且快速的同步反相高效液相色谱 (RP-HPLC) 方法,并基于它们的特定波长对这两种药物的分析进行了验证。在尺寸为 4.6 × 250 mm、5 μm 的 C18 分析柱上使用甲醇:水(pH 3.5)的比例为 70:30 和流速为 0.8 min/mL 进行分离。Box-Behnken 实验设计用于优化这些自变量并分析它们对保留时间 (RT) 等响应变量的影响。两种分析物的理论塔板数和拖尾因子。进行方法验证以确定特异性、线性范围、准确度、灵敏度、稳健性、精密度和耐用性。该方法适用于不同的纳米制剂,即固体脂质纳米颗粒 (SLN)、脂质体 (LIPO)、纳米结构脂质载体 (NLC)。发现分析物的峰得到了很好的分离,并且记录了 TAM 和 SFN 的两个不同的 RT。发现 TAM 和 SFN 的校准曲线在 6–24 μg/mL 的浓度范围内呈线性。所有方法验证标准均在可接受范围内。观察到相对标准偏差 (%RSD) 为 坚固性、精度和坚固性。该方法适用于不同的纳米制剂,即固体脂质纳米颗粒 (SLN)、脂质体 (LIPO)、纳米结构脂质载体 (NLC)。发现分析物的峰得到了很好的分离,并且记录了 TAM 和 SFN 的两个不同的 RT。发现 TAM 和 SFN 的校准曲线在 6–24 μg/mL 的浓度范围内呈线性。所有方法验证标准均在可接受范围内。观察到相对标准偏差 (%RSD) 为 坚固性、精度和坚固性。该方法适用于不同的纳米制剂,即固体脂质纳米颗粒 (SLN)、脂质体 (LIPO)、纳米结构脂质载体 (NLC)。发现分析物的峰得到了很好的分离,并且记录了 TAM 和 SFN 的两个不同的 RT。发现 TAM 和 SFN 的校准曲线在 6–24 μg/mL 的浓度范围内呈线性。所有方法验证标准均在可接受范围内。观察到相对标准偏差 (%RSD) 为 发现 TAM 和 SFN 的校准曲线在 6–24 μg/mL 的浓度范围内呈线性。所有方法验证标准均在可接受范围内。观察到相对标准偏差 (%RSD) 为 发现 TAM 和 SFN 的校准曲线在 6–24 μg/mL 的浓度范围内呈线性。所有方法验证标准均在可接受范围内。观察到相对标准偏差 (%RSD) 为
