PRIMA-1, an acronym standing for p53 reactivation and induction of massive apoptosis, represents a significant advancement in the study of cellular mechanisms and tumor biology. As a small molecule, PRIMA-1′s primary mechanism revolves around its ability to reactivate the tumor suppressor protein p53 in its mutant forms, thereby reinstating its transcriptional activities and its inherent apoptotic functions. This restoration is pivotal in triggering p53-dependent apoptosis, essentially leading to the targeted elimination of tumor cells by reinstating the cell′s natural mechanism for destroying aberrant cells.
