Acute lymphoblastic leukemia (ALL) is the most common hematological malignancy in children. 6-Mercaptopurine (6-MP) is a core chemotherapeutic drug for ALL, but its clinical application is limited by poor solubility, low biological availability, and significant side effects. To address these limitations and to investigate the impact of developmental differences between children and adults on drug absorption, this study developed 6-MP-loaded poly (lactic-co-glycolic acid) nanoparticles (6-MPNs) using a double emulsion-solvent evaporation method. We comprehensively applied high-performance liquid chromatography-mass spectrometry (HPLC-MS) and label-free quantitative proteomics, along with GO functional annotation via eggnog-mapper (v2.0) and protein-protein interaction analysis using STRING (v10.5), to systematically evaluate the pharmacokinetics, intestinal distribution, and duodenal protein expression differences of 6-MPNs in animal models of different ages. All animal studies were approved by the Animal Ethics Committee of Capital Medical University (Approval No.: AEEI-2020-072) and conducted in accordance with relevant guidelines. The results showed that 6-MPNs significantly improved the biological availability of 6-MP. Rats at 4 weeks of age group exhibited higher AUClast (area under curve from time zero to time of last measurable concentration) and Cmax (maximum concentration), faster intestinal absorption, more rapid propulsion, and higher transport efficiency from the intestinal epithelium to the portal vein compared to the rats at 16 weeks of age group. Proteomic analysis revealed that the rats at 16 weeks of age group had significantly lower expression of proteins related to fat digestion and transport, pancreatic secretion, membrane lipid metabolism, brush border recruitment, and microvillus adhesion. These findings suggest that the higher biological availability of 6-MPNs in younger animals may result from longer relative intestinal length, higher intestinal wall transport efficiency and more dynamic barrier construction.

急性淋巴细胞白血病(acute lymphoblastic leukemia, ALL) 是儿童最常见的血液系统恶性肿瘤, 6-巯基嘌呤(mercaptopurine, 6-MP) 是ALL化疗的核心药物。为改善其溶解性差、生物利用度低及毒副作用强等临床应用局限性, 揭示儿童与成人间发育差异对药物吸收的影响, 本研究采用复乳-溶剂蒸发法开发了基于聚乳酸-乙醇酸共聚物[poly (lactic-co-glycolic acid), PLGA] 的6-MP纳米粒(6-MP nanoparticles, 6-MPNs), 综合运用高效液相色谱-质谱联用技术与label-free定量蛋白质组学, 结合eggnog-mapper (v2.0) 进行基因本体(gene ontology, GO) 功能注释和STRING (v10.5) 蛋白质互作网络分析, 系统评价了6-MPNs在不同年龄模型动物中的药代动力学、肠道分布特征及十二指肠蛋白表达差异。所有动物实验研究均由首都医科大学动物伦理委员会批准(批准号: AEEI-2020-072), 且所有动物实验均按照相关指导原则进行。结果显示, 6-MPNs可显著提高6-MP的生物利用度。4周龄组的药-时曲线下面积和达峰浓度更高、在肠段中吸收更快, 推进更迅速、从肠上皮向门静脉的转运效率更高。16周龄组在胰液分泌及膜脂代谢、刷状缘募集、微绒毛黏附、脂肪消化与转运等相关蛋白的表达均显著低于4周龄组, 提示6-MPNs在幼龄动物中较高的生物利用度可能是较长的相对肠段长度、更高的肠壁转运效率、更动态的肠道屏障构建综合作用的结果。
