超分子主体分子姜黄素类化合物包合作用及其抗肿瘤活性的研究
摘要：
姜黄素是一种来自姜黄植物根茎的天然化合物，具有广泛的生物活性，包括抗肿瘤活性。然而，由于其生物利用度的限制以及低溶解度，姜黄素在体内的药物浓度很难维持稳定，从而限制了其抗肿瘤活性。为了克服这些问题，研究人员利用超分子化学的原理来设计一系列的姜黄素类化合物包合体，以提高姜黄素的生物利用度和溶解度，并增强其抗肿瘤活性。
本文主要综述了超分子主体分子包合姜黄素类化合物的研究进展，并讨论了其抗肿瘤活性的机制。研究表明，超分子包合体能够提高姜黄素的稳定性和生物利用度，并在体内释放出姜黄素，从而增强了姜黄素的抗肿瘤活性。此外，超分子主体分子内部的空腔结构可以容纳不同的功能分子，从而赋予包合体附加的抗肿瘤活性，如抗氧化、抗炎和免疫调节活性等。
超分子主体分子包合体的制备方法主要包括溶剂热法、溶剂扩散法、共沉淀法和凝胶滤膜法等。研究人员还利用各种物理和化学性质的表征方法对超分子包合体进行表征，如核磁共振、质谱、动态光散射和差示扫描量热等。这些方法可以用于研究超分子包合体的结构、稳定性和药物释放动力学等方面。
在抗肿瘤活性方面，超分子包合体在体外和体内实验证明其显著的抗肿瘤活性。研究表明，超分子包合体能够抑制肿瘤细胞的增殖和侵袭，并诱导肿瘤细胞凋亡。此外，超分子包合体还可以通过调节细胞信号传导通路、抗氧化和抗炎等机制来发挥抗肿瘤活性。
总结起来，超分子主体分子姜黄素类化合物包合体具有良好的生物利用度和溶解度，并表现出明显的抗肿瘤活性。这些研究结果为开发更有效的抗肿瘤药物提供了重要的理论和实践依据。

Abstract:
Curcumin, a natural compound derived from the rhizome of Curcuma longa, possesses a wide range of biological activities, including anti-tumor activity. However, due to its low bioavailability and poor solubility, maintaining a stable drug concentration of curcumin in the body is challenging, which limits its anti-tumor activity. In order to overcome these limitations, researchers have utilized the principles of supramolecular chemistry to design a series of curcumin-based inclusion complexes to improve its bioavailability and solubility, and enhance its anti-tumor activity.
This paper reviews the research progress of supramolecular host-guest inclusion of curcumin-based compounds and discusses the mechanisms of their anti-tumor activity. Studies have shown that supramolecular inclusion complexes can improve the stability and bioavailability of curcumin, and release curcumin in vivo, thereby enhancing its anti-tumor activity. In addition, the internal cavity structure of supramolecular host molecules can accommodate various functional molecules, endowing the inclusion complexes with additional anti-tumor activities, such as antioxidant, anti-inflammatory, and immune-modulating activities.
Methods for preparing supramolecular host-guest inclusion complexes mainly include solvent thermal method, solvent diffusion method, co-precipitation method, and gel filtration membrane method. Researchers have also used various physical and chemical characterization methods to characterize the supramolecular complexes, such as nuclear magnetic resonance, mass spectrometry, dynamic light scattering, and differential scanning calorimetry. These methods can be used to study the structure, stability, and drug release kinetics of supramolecular inclusion complexes.
In terms of anti-tumor activity, in vitro and in vivo studies have demonstrated the significant anti-tumor activity of supramolecular inclusion complexes. Studies have shown that supramolecular inclusion complexes can inhibit the proliferation and invasion of tumor cells, and induce apoptosis in tumor cells. In addition, supramolecular inclusion complexes can exert anti-tumor activity through mechanisms such as modulation of cell signaling pathways, antioxidant, and anti-inflammatory effects.
In conclusion, supramolecular host-guest inclusion complexes of curcumin-based compounds show improved bioavailability and solubility, as well as significant anti-tumor activity. These findings provide important theoretical and practical basis for the development of more effective anti-tumor drugs.
