  • Publication number: 20110166170
    Abstract: The syntheses of the natural products, avrainvillamide and stephacidin B, are provided. The ?,?-unsaturated nitrone functionality of avrainvillamide and its 3-alkylidene-3H-indole 1-oxide core is shown to covalently and reversibly bond to heteroatom-based nucleophiles. This capability may allow these molecules to bind active site nucleophiles and may provide the basis for designing potent and selective enzyme inhibitors. Both avrainvillamide and its dimer stephacidin B have been reported to exhibit antiproliferative activity, and avrainvillamide has been reported to exhibit antimicrobial activity against multi-drug resistant bacteria. Avrainvillamide has been found to target cytoskeleton-linking membrane protein (CLIMP-63) thereby preventing cells from undergoing mitosis. The invention provides syntheses of these natural products as well as analogs of these natural products and their functional cores.

  • Publication number: 20110105515
    Abstract: (+)-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.
