The present invention provides halichondrin analogs, such as compounds of Formula (I). The compounds may bind to microtubule sites, thereby inhibiting microtubule dynamics. Also provided are methods of synthesis, pharmaceutical compositions, kits, methods of treatment, and uses that involve the compounds for treatment of a proliferative disease (e.g., cancer). Compounds of the present invention are particularly useful for the treatment of metastatic breast cancer, non-small cell lung cancer, prostate cancer, and sarcoma. The included methods of synthesis are useful for the preparation of compounds of Formula (I)-(III) along with naturally occurring halicondrins (e.g., halichondrin B & C, norhalichondrin A, B, & C, and homohalichondrin A, B, & C). Also included are methods for interconverting between the halichondrins, norhalichondrins, and homohalichondrins and their unnatural epimers at the C38 ketal stereocenter through the use of an acid-mediated equilibration.
本发明提供了半龙胆碱类似物,如化合物的结构式(I)所示。这些化合物可能结合到微管位点,从而抑制微管动力学。还提供了合成方法、药物组合物、试剂盒、治疗方法和利用这些化合物治疗增生性疾病(例如癌症)的用途。本发明的化合物特别适用于转移性乳腺癌、非小细胞肺癌、前列腺癌和肉瘤的治疗。所包括的合成方法适用于制备结构式(I)-(III)化合物以及天然存在的半龙胆碱(例如半龙胆碱B和C、诺半龙胆碱A、B和C以及同半龙胆碱A、B和C)。还包括通过使用酸介导的平衡方法在C38酮缩醛立体中心之间相互转化半龙胆碱、诺半龙胆碱和同半龙胆碱及其不自然对映体的方法。
