Abstract

Cancer, particularly non-small cell lung cancer (NSCLC), remains a leading cause of cancer-related deaths, with a dismal 5-year survival rate of approximately 15 %. This underscores the urgent need for novel, safe, and effective targeted therapies. In this study, we synthesized compound 1 for lung cancer treatment, considering the challenges in drug delivery. A new three-dimensional (3D) La(III)-based coordination polymer with the chemical composition of {[La(L)(H₂O)₃]Cl·H₂O}_n (1) (H₂L = (4-(pyridyl-N-oxide)methylphosphonic acid), was successfully self-assembled via diffusion method at room temperature and characterized by single-crystal X-ray diffraction, elemental analyses and FT-IR. Following this, we developed a composite drug delivery material, PCL-CB@CP1@1, and assessed its inhibitory effects on NSCLC cell proliferation. The results demonstrated that PCL-CB@CP1@1 effectively inhibited cell growth by modulating the Nrf2/HO-1/GPX4 signaling pathway. Additionally, molecular docking simulations indicated multiple binding interactions between the La(III) complex and receptor sites, further highlighting its significant biological activity. These findings suggest that PCL-CB@CP1@1 holds potential as a targeted therapeutic agent for lung cancer treatment, offering new possibilities for improving patient outcomes.

电化学性能增强的聚合物复合材料及其在非小细胞肺癌治疗中的应用

癌症，特别是非小细胞肺癌（NSCLC），仍然是癌症相关死亡的主要原因，其5年生存率约为15%。这凸显了对新型、安全、有效的靶向治疗的迫切需求。在本研究中，考虑到药物传递方面的挑战，我们合成了用于肺癌治疗的化合物1。采用扩散法制备了一种新的三维（3D） La（III）基配位聚合物，化学成分为{[La(L)(H2O)3]Cl·H2O}n (1) (H2L =（4-（吡啶基- n -氧化物）甲基膦酸），并通过单晶x射线衍射、元素分析和红外光谱对其进行了表征。在此之后，我们开发了一种复合给药材料PCL-CB@CP1@1，并评估了其对NSCLC细胞增殖的抑制作用。结果表明PCL-CB@CP1@1通过调控Nrf2/HO-1/GPX4信号通路有效抑制细胞生长。此外，分子对接模拟表明La（III）复合物与受体位点之间存在多种结合相互作用，进一步突出了其重要的生物活性。这些发现表明PCL-CB@CP1@1具有作为肺癌治疗的靶向治疗剂的潜力，为改善患者预后提供了新的可能性。

期刊介绍： The Journal of Molecular Structure is dedicated to the publication of full-length articles and review papers, providing important new structural information on all types of chemical species including: • Stable and unstable molecules in all types of environments (vapour, molecular beam, liquid, solution, liquid crystal, solid state, matrix-isolated, surface-absorbed etc.) • Chemical intermediates • Molecules in excited states • Biological molecules • Polymers. The methods used may include any combination of spectroscopic and non-spectroscopic techniques, for example: • Infrared spectroscopy (mid, far, near) • Raman spectroscopy and non-linear Raman methods (CARS, etc.) • Electronic absorption spectroscopy • Optical rotatory dispersion and circular dichroism • Fluorescence and phosphorescence techniques • Electron spectroscopies (PES, XPS), EXAFS, etc. • Microwave spectroscopy • Electron diffraction • NMR and ESR spectroscopies • Mössbauer spectroscopy • X-ray crystallography • Charge Density Analyses • Computational Studies (supplementing experimental methods) We encourage publications combining theoretical and experimental approaches. The structural insights gained by the studies should be correlated with the properties, activity and/ or reactivity of the molecule under investigation and the relevance of this molecule and its implications should be discussed.
