What is Eprenetapopt?

Eprenetapopt is a methylated analogue of PRIMA-1 that covalently modifies mutated p53 through alkylation of thiol groups in its core domain. This is intended to restore wild-type conformation and function to the mutant protein, leading to cell cycle arrest and apoptosis in tumor cells. It is studied in myelodysplastic syndrome, acute myeloid leukemia, and several solid tumors and lymphomas.
