A molecular imprinted polymer (MIP) was computationally designed and synthesized for the selective extraction of salmeterol xinafoate (SLX) from human serum. In this study, semi-empirical PM3 calculations were used to find a suitable functional monomer (FM), the ratio of template (T) to FM, and types of crosslinkers. MIPs were synthesized with 2-hydroxyethyl methacrylate (HEMA) with T:FM mol ratios of 1:6 and 1:4 and ethylene glycol dimethacrylate (EGDMA) or trimethylolpropane trimethacrylate (TRIM) as a crosslinker. On the basis of computational and experimental results, HEMA and TRIM in the mol ratio 1:6 of T-FM (MIP3) were found to be the best choices of FM and crosslinker, respectively. These polymers were then used as a selective sorbent to develop a molecularly imprinted solid-phase extraction procedure followed by high performance liquid chromatography with UV detection for the determination of SLX in serum. The extraction ability of MIP3 was excellent with a recovery of 92.17% ± 2.66% of SLX in spiked serum, and 91.15% ± 1.12% when SLX was spiked as a mixture with another analogous structure. By comparing the performance of the synthesized sorbent with a C-18 cartridge with a recovery of 79.11% ± 2.96%, it was determined that MIP had better performance over the latter. On the basis of these results, the imprinted receptor MIPs, especially MIP 3, can be applied for the direct extraction of SLX in clinical analysis.

通过计算方法合理设计沙美特罗新萘酸印迹聚合物:功能单体和交联剂选择

计算设计并合成了一种分子印迹聚合物 (MIP),用于从人血清中选择性提取沙美特罗新萘酸 (SLX)。在本研究中,半经验 PM3 计算用于寻找合适的功能单体 (FM)、模板 (T) 与 FM 的比率以及交联剂的类型。MIP 是用 T:FM 摩尔比为 1:6 和 1:4 的甲基丙烯酸 2-羟乙酯 (HEMA) 和乙二醇二甲基丙烯酸酯 (EGDMA) 或三羟甲基丙烷三甲基丙烯酸酯 (TRIM) 作为交联剂合成的。根据计算和实验结果,发现 T-FM (MIP3) 摩尔比为 1:6 的 HEMA 和 TRIM 分别是 FM 和交联剂的最佳选择。然后将这些聚合物用作选择性吸附剂,以开发分子印迹固相萃取程序,然后使用紫外检测的高效液相色谱法测定血清中的 SLX。MIP3 的提取能力非常好,在加标血清中的 SLX 回收率为 92.17% ± 2.66%,当 SLX 作为与另一种类似结构的混合物加标时,回收率为 91.15% ± 1.12%。通过将合成吸附剂与回收率为 79.11% ± 2.96% 的 C-18 滤芯的性能进行比较,确定 MIP 的性能优于后者。基于这些结果,印迹受体 MIP,尤其是 MIP 3,可用于临床分析中 SLX 的直接提取。MIP3 的提取能力非常好,在加标血清中的 SLX 回收率为 92.17% ± 2.66%,当 SLX 作为与另一种类似结构的混合物加标时,回收率为 91.15% ± 1.12%。通过将合成吸附剂与回收率为 79.11% ± 2.96% 的 C-18 滤芯的性能进行比较,确定 MIP 的性能优于后者。基于这些结果,印迹受体 MIP,尤其是 MIP 3,可用于临床分析中 SLX 的直接提取。MIP3 的提取能力非常好,在加标血清中的 SLX 回收率为 92.17% ± 2.66%,当 SLX 作为与另一种类似结构的混合物加标时,回收率为 91.15% ± 1.12%。通过将合成吸附剂与回收率为 79.11% ± 2.96% 的 C-18 滤芯的性能进行比较,确定 MIP 的性能优于后者。基于这些结果,印迹受体 MIP,尤其是 MIP 3,可用于临床分析中 SLX 的直接提取。
