Natural products that target p53 for cancer therapy

Area of Science:

• Oncology
• Pharmacology
• Natural Products Chemistry

Background:

• Wild-type p53 is a crucial tumor suppressor, but its frequent mutation and inactivation in cancer drive tumor progression, invasion, and metastasis.
• Reactivating p53 is a promising therapeutic strategy for cancer treatment, with ongoing drug development efforts.
• Natural products, known for their structural diversity and biological activities, are valuable sources for therapeutic agents.

Purpose of the Study:

• To review natural products that inhibit p53 degradation via p53-Mdm2 interaction.
• To discuss natural products promoting p53 reactivation through conformational changes.
• To highlight natural products exhibiting p53-dependent growth inhibition for cancer therapy.

Main Methods:

• Literature review of studies on natural products and p53.
• Analysis of mechanisms involving p53-Mdm2 interaction.
• Investigation of natural product-induced conformational changes in p53.
• Evaluation of p53-dependent growth inhibition assays.

Main Results:

• Several natural products identified that inhibit p53 degradation by targeting the p53-Mdm2 interaction.
• Natural compounds demonstrated the ability to induce conformational changes, leading to p53 reactivation.
• These reactivated p53 molecules exhibited significant p53-dependent inhibition of cancer cell growth.

Conclusions:

• Natural products offer a viable strategy for reactivating the tumor suppressor p53.
• Targeting the p53-Mdm2 interaction and inducing conformational changes are key mechanisms for p53 reactivation by natural compounds.
• These findings support the development of natural product-derived therapeutics for cancer treatment through p53 reactivation.
