TP53 and hepatocellular carcinoma: It is interesting in this regard to mention that a triphenyl derivative with N-tert-butoxycarbonyl-L-ornithine, previously synthesized and characterized in our laboratory, induced apoptosis in human hepatoma HepG2 cells associated with an increase of p53 levels [46], suggesting that the induction pathway of the oncoprotein is influenced by the Ph3Sn-moiety.
