Abstract:
Background:
Mutations in the TP53 gene are the most common among genetic alterations in human cancers, resulting in the formation of mutant p53 protein
(mutp53). Mutp53 promotes proliferation, migration, invasion, and metastasis in cancer cells. Not only does the initiation of oncogenesis ensue due
to mutp53, but resistance towards chemotherapy and radiotherapy in cancer cells also occurs. This review aims to summarise and discuss the
oncogenesis of mutant p53 in cancer cells and introduce the various mutant p53 inhibitors currently being evaluated at the pre-clinical and clinical
stages. Compounds that induce the wild-type conformation on the targeted p53 missense mutation, restore or enhance the DNA binding of mutant
p53, and inhibit cancer cells' growth are highlighted. In addition, the progression and development of the mutant p53 inhibitors in clinical trials are
updated.
Conclusion:
The progress of developing a cancer treatment that may successfully and efficiently target mutant p53 is on the verge of development. Mutant p53
proteins not only initiate oncogenesis but also cause resistance in cancer cells to certain chemo or radiotherapies, further endorse cancer cell
survival and promote migration as well as metastasis of cancerous cells. With this regard, many mutant p53 inhibitors have been developed, some
of which are currently being evaluated at the pre-clinical level and have been identified and discussed. To date, APR-246 is the most prominent
one that has progressed to the Phase III clinical trial.
