In addition, one of the 9 active compounds, adenosine 5’-monophosphate (A5MP), and also its mimic 5-aminoimidazole-4-carboxamide ribonucleotide (AICAR) 5’ phosphate (ZMP) inhibited RAD52 activity in vivo and exerted synthetic lethality against BRCA1 and BRCA2–mutated carcinomas. Here, RAD52 is linked to carcinoma.
