摘要

Cancer remains a major global health challenge. Natural compounds, such as curcumin, resveratrol, genistein, thymoquinone, and paclitaxel, show chemopreventive activity by modulating signaling pathways, including PI3K/Akt, NF-κB, and p53. These agents also promote apoptosis, autophagy, and DNA repair. However, their clinical use is restricted by poor solubility, instability, and low bioavailability. Nanotechnology offers solutions by improving stability, enhancing pharmacokinetics, and enabling targeted delivery. Liposomes, polymeric nanoparticles, dendrimers, and albumin-bound systems amplify the anticancer effects of natural compounds. Preclinical studies confirm improved efficacy, while early clinical trials reveal both promise and barriers. The key translational challenges include immune clearance, large-scale reproducibility, and regulatory approval. This review highlights the synergy between nanotechnology and natural compounds in cancer chemoprevention and outlines opportunities for future research.
