    • The syntheses of the natural products, avrainvillamide and stephacidin B, are provided. The α,β-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. The compounds of the invention may be used in the treatment of diseases such as cancer, autoimmune diseases, and bacterial infection.
    • 提供了天然产物,维生素A和抗抑郁素B的合成。 显示出丙氨酰胺及其3-亚烷基-3H-吲哚-1-氧化物核心的α,β-不饱和硝酮官能团共价和可逆地键合到基于杂原子的亲核试剂。 这种能力可以允许这些分子结合活性位点亲核试剂,并且可以为设计有效和选择性酶抑制剂提供依据。 已经报道了丙氨酰维他命和其二聚杀生物素蛋白B都具有抗增殖活性,据报道,抗谷氨酰胺具有抗多药耐药细菌的抗微生物活性。 已经发现Avrainvillamide靶向细胞骨架连接膜蛋白(CLIMP-63),从而防止细胞发生有丝分裂。 本发明提供这些天然产物以及这些天然产物及其功能核心的类似物的合成。 本发明的化合物可用于治疗诸如癌症,自身免疫性疾病和细菌感染等疾病。
