    Abstract: 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.

    Abstract translation: 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,氟代吡啶或氟代硝基苯部分引入或添加到结构中。 这些衍生物可以用作抗有丝分裂剂,可以认为是微管蛋白的共价修饰剂。 针对每种化合物开发的策略是:i)将氟化亲电试剂(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)添加至天然产物中的现有官能团,ii)将 天然产物中的芳香环与氟化亲电试剂,或iii)将氟化亲电子试剂连接至分子的一部分中的开放化合价,其不会干扰对微管蛋白位点的识别和结合。 基于秋水仙碱,硬脂酸甘油酯,鬼臼毒素,诺考达唑,考布他汀,curacin A,长春碱,长春新碱,多拉司他汀,2-甲氧基雌二醇,二羟基 - 五甲氧基黄烷酮等提供衍生物。
