JNJ-26854165, also named as Serdemetan, is originally developed as an activator of p53, is now regarded as a novel oral Human Double Minute-2 (HDM-2) ubiquitin ligase antagonist. It can increase the level of HDM-2 client proteins, such as p53, by inhibiting the association of HDM-2-client protein complex with the proteosome. It is demonstrated potent anti-proliferative and apoptosis-inducing activity of JNJ-26854165 in a broad range of p53 wild type and mutant tumor models. In vivo, JNJ-26854165 may induce important differences in EFS distribution when comparing to control in 18 of 37 solid tumors and in 5 of 7 of the evaluable ALL xenografts.
