Researchers are developing small molecules to restore the tumor-suppressive function of mutant TP53 (p53) protein, a common event in cancer. This review covers recent advances in targeting mutated p53 for cancer therapy.
Area of Science:
- Oncology
- Medicinal Chemistry
- Molecular Biology
Background:
- TP53 is the most frequently mutated gene in human cancers.
- Mutations in TP53 lead to loss of p53 tumor-suppressive functions, promoting tumor progression, metastasis, and therapy resistance.
Purpose of the Study:
- To provide a comprehensive overview of recent advances in small-molecule modulators targeting mutant TP53 (mut p53).
- To focus on diverse mechanisms for mut p53 reactivation and discuss therapeutic potential.
Main Methods:
- Literature review of small-molecule mut p53 modulators reported between 2020 and 2025.
- Categorization of modulators based on their mechanisms of action (covalent electrophiles, metal-based coordinators, non-covalent modulators, chemical inducers of proximity).
Main Results:
- Significant progress in developing small molecules to restore p53 tumor suppressor activity.
- Highlighting key clinical candidates and emerging compounds with different modulation mechanisms.
- Discussion of mechanisms of action and therapeutic potential of these compounds.
Conclusions:
- Small-molecule modulators offer promising therapeutic strategies for restoring p53's tumor-suppressor function in cancer.
- Continued research and development in this area hold potential for novel cancer treatments.
