p53 Activators

p53 activators are a class of chemical compounds that have the ability to stimulate or enhance the activity of the p53 protein. The p53 protein, also known as the guardian of the genome, is a crucial regulator of cell cycle progression and plays a pivotal role in the development and progression of cancer. p53 is a transcription factor that is activated in response to various cellular stresses, such as DNA damage, oxidative stress, and oncogene activation. When activated, p53 regulates the expression of a wide range of target genes involved in cell cycle arrest, DNA repair, apoptosis (programmed cell death), and senescence (cellular aging). These processes collectively help to maintain genomic stability and suppress the formation of cancerous cells.However, in many cancer cells, the p53 pathway is disrupted or mutated, leading to the loss of p53 function. As a result, these cancer cells can evade cell cycle arrest, resist apoptosis, and continue proliferating uncontrollably. Restoring or enhancing the activity of p53 in cancer cells has emerged as a possible cancer-fighting strategy in vitro, and p53 activators have been developed to achieve this goal.There are several classes of p53 activators, each with unique mechanisms of action. Some p53 activators work by directly binding to the p53 protein and stabilizing its structure, its degradation. This stabilization allows p53 to accumulate in the cell nucleus and initiate its transcriptional activity. Other activators function indirectly by modulating upstream regulators or downstream effectors of the p53 pathway. By reactivating the p53 pathway, these compounds aim to restore the tumor-suppressive functions of p53, induce cell cycle arrest, promote DNA repair, and trigger apoptosis in cancer cells. Overall, p53 activators represent a promising avenue for fighting cancer cells by targeting and activating one of the most critical tumor suppressor pathways in the human body.

NSC-207895 is a potent small molecule that selectively enhances the stability of the p53 protein, facilitating its interaction with DNA. By promoting the formation of p53 tetramers, it effectively increases the protein's binding affinity to specific promoter regions, thereby amplifying the transcription of target genes involved in apoptosis and cell cycle regulation. Its unique structural features enable efficient cellular uptake, allowing for swift modulation of p53-mediated pathways.

RG-7112

939981-39-2sc-507292
10 mg
$520.00
(0)

RG7112 is a small molecule that inhibits the interaction between MDM2 and p53. MDM2 normally binds to p53 and marks it for degradation. By inhibiting this interaction, RG7112 prevents MDM2 from tagging p53 for degradation, leading to the stabilization and activation of p53, which can then carry out its tumor-suppressing functions.
