Cat. No. 1267
Chemical Name: 1-(4-Methylphenyl)-2-(4,5,6,7-tetra
Biological ActivityInhibitor of p53; reversibly blocks p53-dependent transcriptional activation and apoptosis. Protects against neuronal death in models of stroke and neurodegenerative disorders. Active in vivo; protects mice from the side-effects of cancer therapy associated with p53 induction. Supresses self-renewal of embryonic stem cells. Also aryl hydrocarbon receptor (AHR) agonist, causes upregulation of AHR target gene CYP1A1 (EC50 = 1.1 μM). Cyclic analog available (Cat. No. 3843).
