Interruption of binding of MDM2 and p53 protein and therapeutic application thereof

摘要

A method of identifying a compound which interferes with the binding of MDM2 to human p53 has been determined. This method comprises forming a mixture between MDM2 and a fragment of human p53 consisting of 6 to 28 amino acids comprising TFSDLW (SEQ ID NO:2), adding a test compound to the mixture and determining the quantity of protein bound to the other before and after adding the compound. A compound which decreases the amount of binding of the two proteins to each other is a compound which interferes with the binding of MDM2 to human p53.
