Abstract:
Pancreatic cancer, especially pancreatic ductal adenocarcinoma, is known for its aggressive nature, late diagnosis, and resistance to standard treatments. This review demonstrates the therapeutic potential of phytochemicals as multitarget agents in pancreatic cancer, emphasizing their molecular mechanisms, pharmacological properties, and translational relevance. Important carcinogenic signaling pathways, such as KRAS/MAPK, PI3K/Akt, NF-κB, STAT3, Hedgehog, and Wnt/β-catenin, are modulated by phytochemicals like curcumin, quercetin, resveratrol, and others. These substances demonstrate anticancer effects by suppressing epithelial-mesenchymal transition, inducing apoptosis, reducing proliferation and angiogenesis, and modulating oxidative stress. Preclinical research indicates consistent multipathway targeting and potential enhanced efficacy with traditional chemotherapeutics, although evidence from clinical studies remains limited and inconsistent. New strategies to improve drug stability, target tumors more effectively, and enhance treatment outcomes involve the use of combination medicines and nanotechnology-based delivery systems. The gap between preclinical effectiveness and clinical translation continues due to insufficient large-scale trials, diverse study designs, and a lack of standardized dosing strategies. Phytochemicals show potential as multitarget treatments for pancreatic cancer, but their clinical application is inhibited by pharmacokinetic challenges and insufficient validation.
Insights
Phytochemicals show promise in fighting pancreatic cancer by targeting multiple pathways. Further research is needed to overcome challenges for effective clinical use of these natural compounds.
Area of Science:
- Oncology
- Pharmacology
- Natural Products Chemistry
Background:
- Pancreatic cancer, particularly pancreatic ductal adenocarcinoma, is aggressive, diagnosed late, and resistant to conventional therapies.
- Phytochemicals, derived from plants, are increasingly investigated for their potential anticancer properties.
- Multitargeting key signaling pathways is a promising strategy for overcoming pancreatic cancer's complexity.
Purpose of the Study:
- To review the therapeutic potential of phytochemicals as multitarget agents against pancreatic cancer.
- To elucidate the molecular mechanisms and pharmacological properties of phytochemicals in pancreatic cancer.
- To assess the translational relevance and clinical applicability of phytochemical-based pancreatic cancer therapies.
Main Methods:
- Literature review of preclinical and clinical studies on phytochemicals in pancreatic cancer.
- Analysis of molecular mechanisms, including modulation of KRAS/MAPK, PI3K/Akt, NF-κB, STAT3, Hedgehog, and Wnt/β-catenin pathways.
- Evaluation of phytochemical effects on cancer hallmarks like proliferation, apoptosis, angiogenesis, and epithelial-mesenchymal transition.
Main Results:
- Phytochemicals like curcumin, quercetin, and resveratrol modulate multiple cancer-related signaling pathways.
- Anticancer effects include suppressed epithelial-mesenchymal transition, induced apoptosis, reduced proliferation and angiogenesis, and modulated oxidative stress.
- Preclinical data suggest synergistic potential with chemotherapeutics, but clinical evidence is limited and inconsistent.
Conclusions:
- Phytochemicals exhibit significant potential as multitarget agents for pancreatic cancer treatment.
- Challenges in clinical translation include pharmacokinetic limitations, insufficient validation, and lack of standardized dosing.
- Combination therapies and nanotechnology-based delivery systems may enhance efficacy and overcome current limitations.
