    • Derivatives of known tubulin-binding compounds are provided in which a (poly)fluorobenzene, a fluoropyridine, or a fluoronitrobenzene moiety is incorporated or added to the structure. These derivatives can be used as antimitotic agents and can be considered covalent modifiers of tubulin. The strategy developed for each of the compounds is to i) append a fluorinated electrophile (e.g., pentafluorophenylsulfonamido, 2-fluoropyridyl, or 3,5-dinitro-4-fluorophenyl) to an existing functional group in a natural product, ii) replace an aromatic ring in a natural product with a fluorinated electrophile, or iii) attach a fluorinated electrophile to an open valence in a portion of the molecule that will not interfere with recognition and binding to the tubulin site. Derivatives are provided based on colchicine, steganacin, podophyllotoxin, nocodazole, combretastatin, curacin A, vinblastine, vincristine, dolastatin, 2-methoxyestradiol, dihydroxy-pentamethoxyflavanone and others.
    • 提供了已知的微管蛋白结合化合物的衍生物,其中将(聚)氟苯,氟代吡啶或氟硝基苯部分掺入或添加到该结构中。 这些衍生物可用作抗有丝分裂剂并且可以被认为是微管蛋白的共价修饰剂。 为每种化合物制定的策略是i)将天然产物中的现有官能团上的氟化亲电体(例如五氟苯基磺酰胺基,2-氟吡啶基或3,5-二硝基-4-氟苯基) 具有氟化亲电体的天然产物中的芳香环,或iii)在分子的一部分中将氟化亲电体连接至开放价态,其不会干扰识别和结合微管蛋白位点。 衍生物基于秋水仙碱,steganacin,鬼臼毒素,诺考达唑,考布他汀,curacin A,长春花碱,长春新碱,多卡他汀,2-甲氧基雌二醇,二羟基 - 五甲氧基黄酮等。
