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.
本文介绍了自然产物avrainvillamide和stephacidin B的合成方法。其中,avrainvillamide的α,β-不饱和亚硝基功能团和其3-烷基亚甲基-3H-吲哚1-氧化物核心被证明能够与杂原子型亲核试剂共价、可逆结合。这种能力可能使这些分子能够结合活性位点的亲核试剂,并为设计有效且选择性的酶抑制剂提供基础。avrainvillamide和其二聚体stephacidin B均已被报道具有抗增殖活性,而avrainvillamide还被报道对多重耐药菌具有抗菌活性。研究发现,avrainvillamide能够靶向细胞骨架连接膜蛋白(CLIMP-63),从而防止细胞进行有丝分裂。本发明提供了这些天然产物以及它们的类似物和功能核心的合成方法。这些化合物可以用于治疗癌症、自身免疫性疾病和细菌感染等疾病。
