(+)-Avrainvillamide, a naturally occurring alkaloid with antiproliferative activity, is shown to bind to the oncoprotein nucleophosmin. Nucleophosmin is known to regulate the tumor suppressor protein p53 and is overexpressed in many different human tumors. The invention provides methods of modulating nucleophosmin and p53 using (+)-avrainvillamide and analogues thereof. These compounds may provide leads for the development of novel anti-cancer therapies that target nucleophosmin.
