Acridine form IX

Acta Crystallographica Section E: Crystallographic Communications, 2019
We report a new polymorph of acridine, C13H9N, denoted form IX, obtained as thin needles by slow evaporation of a toluene solution. The structure was solved and refined from powder X-ray data. The structures of five unsolvated forms were previously known,

Synthesis, DNA-Binding and Antiproliferative Properties of Acridine and 5-Methylacridine Derivatives

Molecules, 2012
Several acridine derivatives were synthesized and their anti-proliferative activity was determined. The most active molecules were derivatives of 5-methylacridine-4-carboxylic acid. The DNA binding properties of the synthesized acridines were analyzed by

c‐Rel–dependent Chk2 signaling regulates the DNA damage response limiting hepatocarcinogenesis

Hepatology, EarlyView., 2022
In response to genotoxic injury, c‐Rel upregulates ATM‐Chk2‐p53 pathway DNA damage proteins to limiting hepatocarcinogenesis. Abstract Background and Aims Hepatocellular carcinoma (HCC) is a leading cause of cancer‐related death. The NF‐κB transcription factor family subunit c‐Rel is typically protumorigenic; however, it has recently been reported as a
